How Long Does Dental Anesthesia Last

anesthesia

Inefficient and long-lasting formulations

In the dental direction for a long time there are drugs that block the signal of pain. To the previous generation include Novocaine, Lidocaine. After their introduction, patients do not have to ask the question, how much is the dental anesthesia. The duration of action is very short from 15 minutes to half an hour. Although Lidocaine can maintain its effect for up to an hour. They are ineffective and sometimes cause an undesirable reaction (Allergy).

How much does anesthesia work on the tooth, if modern drugs are used

A new generation of local drugs includes vasoconstrictor compounds, which is necessary for the duration of their action.

How much does anesthesia work in the treatment of teeth of this type? The drug allows you to achieve the result of anesthesia with the rapid onset of blocking nerve impulses. Due to the vasoconstrictive effect of the new generation of drugs allows not minutes to calculate the time of action, and in hours. To do this, the composition (Articaine) is additionally added adrenaline or the drug itself (Mepivacaine) has the ability to have a narrowing effect on the vessels.

How long depart from the anesthesia after treatment of the tooth

If we talk about how many hours departs tooth anesthesia after a very strong connection (Biluochun), then this term will be for a few hours. Ultrakain, Ubistesin can operate 3 to 4 hours. They are most often preferred in dentistry. All drugs with adrenaline have different content and are selected according to need

How long does the anesthesia of the tooth

Before visiting the dentist, we are concerned about how long the anesthesia of the tooth passes due to fear of feeling pain. Especially if we are talking about the removal of the nerve. And when it comes to the extraction of the retention structures of the mastication, then how much is the anesthesia after tooth extraction we are interested in without a doubt.

Of course, with the same result to say how long the anesthesia of the tooth at all at once can not.
All depends on:

The selected tool.

State of soft tissue at the time of administration. Inflammation with an acidic environment will neutralize the alkaline composition of the anesthetic, and it may not have a high effect.
The selected route of administration (infiltration, apical, application, and wiring, intraligamentary).

In addition, the General state of the human system affects how much the anesthesia of the tooth passes through. How much the anesthesia of the tooth leaves even after the anesthetic for the usual treatment of hard tissues by the drill and the residual effects will also be different for everyone. Someone will change the proportionality of the face, with the curvature of the smile or to be felt as numbness of one side of the lips. And someone will be hard to chew. It depends on the place of injection, that is, the type of anesthesia.

The injection site for intraligamentary effects on soft structures (area of one masticatory element)

The introduction of a special solution, what is the effect

Analgesia, which is felt in the first few minutes after the injection of the solution, gives numbness of the point of pricking. The effect is never the same.

Affect the penetration of the drug features of the mucous, blood vessels of the patient. So accurately and the opposite time of excretion of the body has its own nuances. It happens that the anesthesia does not depart after tooth extraction even for two days. This is extremely rare, but it happens.

Usually the period after which the anesthesia of the tooth leaves is from 3 to 5 hours. The amount of the injected drug is also taken into account. The more he entered, the longer term how much does the anesthesia after removal of the tooth.

Freezing of the treatment site is selected with a shorter duration of pharmaceutical substances. And it is different from how much anesthesia passes after tooth extraction. So as to extract chewable element selected drugs as long as possible in action.

How much does the anesthesia of the tooth go away

Most dental treatments include pain relief. The reason for this is the extreme sensitivity of the teeth to pain. Without addressing the pain of the susceptibility can be performed only treatment of the carious lesions of the tooth at the initial stage when we still hadn’t started the inflammatory process in polovoy the camera.

But when the inflammation began, as a rule, the tooth hurts by itself, even without any effects on it. If the masticatory organ is subjected to temperature (for example, from chilled water or even just from a jet of cool air) or mechanical action, the pain is magnified and can even become unbearable.
In dentistry, there are three main approaches to eliminate the feeling of pain in medical manipulations on the teeth:

• killing pulp with arsenic compounds and other chemicals of similar action;
• local anesthesia with novocaine, lidocaine and other anesthetics;
• general anesthesia.

The first approach is now considered outdated and is used mainly either in the presence of contraindications to anesthesia or inexperienced and insufficiently qualified doctors. General anesthesia is rarely used-in special situations where appropriate indications are available-for example, in long and complex operations, such as the installation of transosal implants.

Local anesthesia today is the most widespread method of anesthesia. In this case, with the help of appropriate medicines, the area of the oral cavity where medical procedures are carried out is deprived of pain susceptibility.

However, the effect of the drug is not limited to the tooth and adjacent tissues. After the injection, the patient feels numb cheek and lip. The result is a difficult speech, and it still continues for some time after leaving the office. In this regard, the patient may have a legitimate question about how long this condition can last. Sometimes in life, such a question can be of fundamental importance. In fact,can teeth be treated with anesthesia on the same day as a public appearance?

On the other hand, medical errors during the injection of the drug, as well as factors related to the characteristics of the patient’s body and General health, can cause complications. Therefore, the patient may be concerned about too long duration of anesthesia. How much normally should be the duration of the drug, and in some cases there is reason for concern. So,

How long does tooth anesthesia take

During many medical procedures, analgesia is performed on the teeth, which can be both local and General. General anesthesia, which is an artificial deprivation of the patient’s consciousness, is rarely used in the treatment of teeth – usually with special indications. So, General anesthesia is applied:

  • if the patient has certain mental disorders;
  • in epilepsy;

during the treatment of teeth in children in the presence of their insurmountable fear of dentists and dental office.
with a long duration and complexity of surgery.

Local anesthesia is widely used in dentistry and today it more and more displaces the old method of dental treatment with the devitalization of the nerve with arsenic. The basis of local anesthesia is the property of a number of chemicals to suppress the conductivity and reduce the excitability of nerves that transmit pain signals to the brain.

The impact on the nerves in order to suppress their pain sensitivity can be carried out in two ways. In the first case, the drug is injected directly into the area where dental manipulations are carried out. This is called infiltration anesthesia.

In the second case, the conductive ability of one of the main nerves transmitting signals from certain areas of the face and mouth is suppressed. In this case, pain sensitivity loses not one tooth, and an entire section of your jaw and face.

Conductive analgesia is more difficult and risky than infiltration, and also requires high qualification of the doctor. However, it provides a stronger and longer lasting effect and allows performing dental procedures directly on the whole group of teeth.

Regardless of the method of anesthesia, some time after the injection, the anesthetic diffuses through the tissues from the area of its impact. Thus, the analgesic effect gradually weakens, and then disappears altogether. In the future, the drug is metabolized and excreted from the body.

The duration of the analgesic effect depends on the following factors:

  • the chemical nature of the anesthetic;
  • method of anesthesia;
  • the introduction of the drug;
  • individual characteristics of the patient.

How much is the anesthesia of the tooth, depending on the nature of the anesthetic

Various chemicals, which are the main active components of drugs for anesthesia, can produce an anesthetic effect of different duration. The duration of anesthesia is also influenced by the individual ability of the patient’s body to deactivate the anesthetic — some anesthetic metabolism is faster, others slower. If you do not consider this factor and consider the duration of the average, then this parameter can be divided into the following categories of anesthetics:

  1. Anesthetics with a short duration of exposure, which include, in particular, novocaine, acting about a quarter of an hour.
  2. Anesthetics that have an average duration of analgesic effect – these include lidocaine and trimecaine, acting for about half an hour.
  3. Drugs for long-term pain relief, such as bupivacaine, which eliminates pain sensitivity for two hours or more.

Factors affecting the duration of anesthesia

The duration of the absence of pain sensitivity is influenced by various factors. These include:

The presence of inflammatory processes in the area of analgesic injection. In inflamed tissues, an acidic environment is formed. Anesthetics are substances whose solutions have an alkaline reaction. Therefore, in the area of the inflammatory process, acid and alkali are neutralized, and therefore the duration of anesthesia is small. Sometimes the anesthetic may not produce the desired effect at all.

The presence in the preparation of substances having a vasoconstrictive effect, such as adrenaline or norepinephrine. Due to the narrowing of the vessels, the diffusion of the anesthetic from the area of exposure slows down, which increases the duration of anesthesia. In the presence of a vasoconstrictor in the drug, the patient feels numbness stronger and longer.

The duration of the analgesic effect increases as the content in the anesthetic vasoconstrictor.
The age of the person – the statistical data indicate that in elderly patients anesthetics are weaker than the young. The duration of anesthesia in older patients is also less.

The presence of chronic hepatic and renal pathologies. The liver is responsible for the deactivation of painkillers, and the kidneys – for their removal from the body. Because, under appropriate diseases anesthesia more prolonged.
The quality of the procedure.

If the anesthetic injection is done correctly, the effect will have the desired duration. If the injection was made mistakes, for example, in choosing the injection site, the drug will not have the proper effect on the nerves, because the analgesic effect will be weaker and shorter in duration – until the preservation of pain during treatment.
Method of anesthesia-conductive anesthesia is characterized by a longer effect than infiltration.

The duration of anesthesia depends on which jaw anesthesia is performed. So, in the case of the upper jaw, the duration of the effect can be about two and a half hours. During anesthesia in the lower jaw match other nuances of the anesthesia will last four hours or more, as in this case, a deeper injection of the drug.

How long does the anesthesia of the tooth take depending on its type

The duration of anesthesia is very dependent on the technique used. Depending on the tasks facing the dentist, different ways of eliminating pain susceptibility, characterized by different duration of the effect, can be used.

The shortest duration of action in the application of anesthesia produced without injection. The method consists in applying a special anesthetic gel to the oral mucosa. The anesthetic contained in the gel penetrates the mucosa and produces its effect. This anesthesia works for about a quarter of an hour.

Methods of application anesthesia. On a cotton swab, the doctor applies a gel form of anesthetic and rubs it into the mucous membrane of the oral cavity.

When using infiltration anesthesia – injection of anesthetic directly into the area where dental manipulations are carried out-the effect is less prolonged than in the case of the conductor method. For the duration of lack of feeling pain considerable influence of the applied drug.

The greatest duration of anesthesia takes place in the case of conductive anesthesia. This method consists in the injection of anesthetic into the exit points of the main nerve lines. In this case, under the influence of anesthesia is the whole area of the jaw and face. In some cases, pain relief using the conductor method can last six hours. It is a conductive technique of anesthesia used in long and complex operations.

What to do if the anesthesia of the tooth does not go away for a long time

In some cases, anesthesia and the numbness that accompanies it last longer than necessary. In this case, you can independently increase the speed of the process of withdrawal of anesthesia. To do this, apply a warm but not hot compress to the numbness area or just massage the appropriate area.

In this case, there will be vasodilation, and therefore increase the rate of diffusion of the drug from the injection zone. However, before applying such procedures, it is necessary to consult a doctor. In addition, the compress and massage can not be used after tooth extraction.

To numbness was not too long, before going to the dentist should not drink alcohol and eat products containing a large amount of fat. Alcohol and fatty foods lead to an increase in the load on the liver, which complicates the metabolism of the drug. Do not take alcohol after anesthesia of the tooth.

However, in some cases, too long numbness can be a sign of complications, in particular, nerve damage. However, if, from the patient’s point of view, the numbness does not go away for too long, this is not a reason to sound the alarm. The norm is when the analgesia on the upper jaw effect lasts no more than two and a half hours, and in the case of the lower jaw – four and a half. In case of too long numbness, it is necessary to consult a doctor.

If numbness does not go away for too long, it may indicate nerve damage. In this situation, you may need to participate in solving the problem not only the dentist, but also the neurologist. In some cases, to eliminate numbness requires the use of physiotherapy.

How long it takes a tooth anesthesia

Today, quality dental treatment is almost always carried out with anesthesia. Doctors have a variety of tools that are characterized by different strength and duration of the effect. The main issue of concern to patients who came to the dentist is how long the anesthesia lasts. Some drugs have such a powerful effect that a person’s face is modified and a smile is distorted. Today we will understand how much anesthesia and freezing of the tooth leaves.

Anesthesia in dentistry

Anesthesia today is done not only with a hysterectomy. Local influence helps to work calmly dentist with the patient, because he will be sure that the person once again does not move from discomfort.

Anesthesia in dentistry

The person himself will feel much better, because he will not feel much pain. As a rule, anesthesia is carried out with gingivitis, periodontal disease and many other pathologies. Many people do not tolerate even the noise of the boron machine, so when filling the channels, anesthesia is also often done.

Thus, anesthesia in the dental field is one of the most important components, without which quality patient care is simply impossible.

Types of anesthesia

No matter what kind of pain medication you choose, they operate on the same principle. The substance has an effect on the nerve impulse responsible for pain. After a certain period of time, the drug begins to dissolve. In this case, the patient may feel pain, which with proper treatment should take place very quickly.

In dentistry there are the following types of anesthesia:

application. It is characterized by a short duration of action. Sold in the form of sprays or gels, used exclusively for short-term treatment, can be used as an additional anesthesia, so as not to introduce more serious drugs, infiltration. In infiltration anesthesia, the drug is administered to the mucous part of the gums by injection, it is used in the process of cleaning the channels of the tooth.

The effect of this manipulation lasts about an hour conductive anesthesia is injected by injection into the area of the trigeminal nerve. In the process of this manipulation, a person can feel severe pain. this should immediately tell the doctor. The specialist decides to make another injection from the effects of anesthesia.

Such drugs used in the treatment of permanent teeth, surgery gums, deponirovanie of teeth, prolonged dental procedures, intraligamentary anesthesia is used for anesthesia of a single tooth, which in the future holds all sorts of manipulation. For these purposes, the anesthetic is injected into the area of the painful tooth. It is used in the removal of wisdom teeth or more serious interventions. It helps the patient relax and increases the effect of other painkillers.

If you take Valerian before a dental procedure, you will significantly increase the effect of pain relief of other drugs.

There are also some nuances of analgesia of the upper and lower jaws. It depends on the structure of each. Often numbness extends to other parts of the face, such as the tongue, lips, cheeks. Nerves are very close to each other, so it happens.

How long is the freeze of the tooth

The duration of action depends on the type of drug:

those that are applied to the cheeks or gums, are only for a few minutes;
if the patient is injected with an anesthetic into the upper jaw, the effect can last about two and a half hours, based on the individual characteristics of the body, the amount of medication, the depth of the injection, etc.;
when manipulating the lower jaw, the drug is administered more deeply. In this regard, the drug is not so fast, and numbness can last about four hours, sometimes more. It all depends on what kind of tooth was anesthetized.

For each body anesthesia acts differently, but if the effect lasts for days, you need to contact a doctor as soon as possible.

What affects the duration of the procedure

The time of exposure to a particular drug depends on many factors:

inflammatory processes in the injection area. Substances for anesthesia are alkaline, and in the area of inflammation is dominated by acidic environment, which eliminates the action of alkali. It is for this reason that numbness in the presence of an inflammatory process departs instantly, and sometimes does not work at all;
vasoconstrictors in the drug. As a result of the impact of these components, the vessels are narrowed, which in turn reduces the speed of exposure. Due to this, the duration of the analgesic effect increases and the drug departs much more slowly;

People in adulthood is quite difficult to be anesthetized

If a specialist has introduced the drug incorrectly, the substance will not reach all the necessary nerve impulses and the effect will be very weak;
a kind of anesthesia. After infiltration anesthesia numbness is much faster than in all other cases.

What can be the consequences of anesthesia

Often allergic people have intolerance to a particular drug.

  • In other words, there is an allergic reaction that can manifest itself in two ways:
  • dermatitis that occurs directly in the area of injection and is manifested by swelling;
    urticaria and angioedema, which is very rare.

Experienced doctors always do tests on the patient’s reaction. It should not be confused with tachycardia, dizziness and sweating with the reaction to the drug. This Allergy makes itself felt skin manifestations: swelling, rash, itching, redness, irritation. In a particularly difficult situation arises in patients with anaphylactic shock and complication breathing.

Experienced doctors always do tests on the patient’s reaction

If you are allergic, the doctor will choose the right drug for you, which will not harm your body. All Allergy symptoms will disappear after a few minutes.

Other complications

In addition to these consequences, patients often complain of other symptoms that occur as a result of the introduction of an anesthetic injection. Even an experienced doctor is very difficult to predict the reaction to a single drug.

In each dental clinic, there are safety measures that involve the implementation of certain measures, especially if the anesthesia does not pass after the treatment of the tooth for a long time.

The most common side effects:

  • problems with gastrointestinal tract;
  • soreness in the throat and mouth;
  • chills and malaise, accompanied by fragility of bones and loss of strength;
  • loss of concentration;
  • itching and other skin manifestations.

Also, there are more serious phenomena:

  • infection in the lungs;
  • defeat of healthy teeth;
  • discharge the pain relief ahead of time.

If the doctor has calculated the wrong dose of the drug or the rules of administration of pain medication have been violated, the following complications are likely:

  • partial nerve damage
  • tissue necrosis
  • anaphylactic shock
  • Quincke edema;
  • disorders in the brain

In order to prevent the occurrence of such complications, it is necessary to consult a qualified doctor in a timely manner.

A person should know well the characteristics of a particular drug, namely, how much anesthesia affects the tooth and how long it takes after the intervention.

Numbness after anesthesia usually lasts for four hours

How long does the numbness hold?

Usually sensitivity is restored within four hours. Refer to the doctor is necessary if the anesthesia is held after the treatment of the tooth after this time.

The specialist needs to tell you what diseases you suffer from, whether you take any medications and what exactly and more. Based on this information, the doctor will decide on further assistance. Sometimes administered drugs that eliminate the effect of freezing, and sometimes the patient needs hospitalization. If you feel very strong pain after anesthesia, you should also tell your doctor about it.

Within two hours after freezing, you need to refrain from eating. Do not neglect this principle, as in most cases, unpleasant complications are felt through the fault of the person.
