Dental Treatment Under General Anesthesia

What Is General Anesthesia?

 When Is It Considered in Dental Treatment?

General anesthesia is a controlled state of unconsciousness induced by medications and reversed when their administration is stopped. During general anesthesia, the patient is not aware of what is happening around them and does not respond consciously to painful stimuli during surgical or dental procedures. Breathing, circulation and other essential vital functions are assessed throughout the procedure and supported when necessary by the Specialist in Anesthesiology and Reanimation.

In dentistry, general anesthesia is not a routine method used for every patient or every dental procedure. A large proportion of dental treatments can be carried out under local anesthesia while the patient is awake. However, for some children and adults, other anesthesia options may be considered because of severe dental fear, a strong gag reflex, difficulty cooperating with treatment, certain special healthcare needs or the need for extensive dental treatment.

For this reason, the main purpose of general anesthesia is not simply to put the patient “to sleep”. What matters is assessing the patient's medical condition together with the dental treatment required, so that the procedure can be carried out under appropriate anesthesia conditions.

How Does General Anesthesia Work?

The medications used during general anesthesia act on the central nervous system to produce controlled unconsciousness. This state is different from normal sleep. During general anesthesia, the patient cannot be woken in the usual way by being spoken to or by painful stimuli.

Anesthetic medications can also affect muscle tone, breathing and some of the reflexes that protect the airway. For this reason, keeping the airway open and supporting breathing when necessary are key parts of managing general anesthesia.

The anesthesiologist's role is not limited to giving medications. Throughout the procedure, the patient's heart rhythm, blood pressure, oxygenation, breathing and other necessary physiological parameters are monitored. The anesthetic technique and medications are chosen according to the patient's age, weight, general health, current medications and the nature of the planned procedures.

The Royal College of Anaesthetists states that general anesthesia produces a state of unconsciousness similar to deep sleep and that the risks of anesthesia can vary depending on the person's health and the procedure being performed.

How Is Dental Treatment Under General Anesthesia Carried Out?

When dental treatment under general anesthesia is planned, the process begins with a dental assessment and an anesthesia assessment.

The dentist identifies the existing problems in the mouth, the treatments needed and the alternatives available. Where necessary, methods such as panoramic radiography, intraoral imaging or dental CT (tomography) may be used.

The Specialist in Anesthesiology and Reanimation assesses the patient's general health. Existing illnesses, current medications, known allergies, previous surgeries and past experiences with anesthesia are reviewed.

While the dentist plans the dental treatment, the Specialist in Anesthesiology and Reanimation carries out the patient's anesthesia assessment and anesthesia management.

On the day of the procedure, general anesthesia is started once the necessary checks have been completed. Monitoring appropriate to the patient's clinical condition is applied and the airway is managed. While the dental team carries out the planned procedures, the anesthesia team monitors the patient's physiological condition.

When treatment is complete, the anesthetic medications are stopped and the patient is taken through a controlled recovery process. The decision to discharge is based not on a fixed amount of time having passed, but on the patient having recovered sufficiently from a clinical point of view.

What Is Assessed Before General Anesthesia?

Pre-procedure assessment is one of the most important parts of the general anesthesia process.

Not only the patient's oral and dental health but also their general health must be taken into account. In the anesthesia assessment, heart and respiratory conditions, current medications, allergies and previous experiences with anesthesia are important.

If the patient has previously had a difficult airway, severe nausea and vomiting, an allergic reaction or any other problem during anesthesia, this information should be shared with the healthcare team.

Not every patient needs the same laboratory tests. The investigations required are determined according to the patient's age, health status and the nature of the planned procedures.

In children, any changes in health before the procedure, such as fever, cough or a respiratory tract infection, should also be reported to the anesthesia team.

Why Is Fasting Important Before General Anesthesia?

Before general anesthesia, patients are given individual instructions about eating and drinking.

The purpose of this preparation is to reduce the risk associated with stomach contents entering the airway during anesthesia. However, it is not appropriate to give every patient the same fasting period.

The individual fasting and fluid instructions given by the anesthesia team should be followed, rather than general time frames found on the internet.

Regularly used medications should not be stopped or their doses changed without consulting a physician. If the preparation instructions cannot be followed, the healthcare team should be informed before the procedure.

Who May Be Considered for General Anesthesia in Dental Treatment?

General anesthesia is not necessary for every patient. In deciding whether it is appropriate, not only the number of procedures required but also how the patient tolerates treatment is important.

Some people with severe dental fear may postpone dental treatment for a long time or experience marked panic during treatment. At first, options such as communication, gradual familiarization, local anesthesia and, in suitable patients, sedation may be considered. If the necessary treatment still cannot be carried out, general anesthesia may be considered.

Some people with a strong gag reflex may be unable to tolerate an oral examination, impressions, X-rays or longer dental procedures. In suitable patients whose necessary dental treatment cannot be carried out because of gagging, nausea or vomiting, other anesthesia options may be considered.

In patients with special healthcare needs, characteristics related to communication, sensory sensitivity or movement control can make dental treatment more difficult. However, having special healthcare needs or a particular diagnosis does not, on its own, mean that general anesthesia is required.

Some patients may need extensive dental treatment and also have difficulty cooperating with treatment. In these cases too, the need for general anesthesia should be assessed on an individual basis.

General Anesthesia for Children's Dental Treatment

The decision to use general anesthesia in children must be made on a particularly individual basis.

The child's age, developmental level, dental treatment needs, the presence of pain or infection, previous dental experiences and ability to cooperate with treatment are assessed.

General anesthesia is not necessary for every fearful child or for every child with multiple cavities.

For some children, becoming familiar with the clinical environment, explanation, behavior guidance and local anesthesia may be sufficient. Sedation may be considered in suitable patients. For some children in whom the necessary treatment cannot be carried out with these methods, general anesthesia may be an option.

In its current guidance, the American Academy of Pediatric Dentistry defines general anesthesia as one of the advanced behavior guidance techniques and recommends that the decision take into account the child's medical history, developmental characteristics, dental needs, previous behavior, alternative methods, and risks and benefits together.

General Anesthesia for Patients with Special Healthcare Needs

Additional arrangements may be needed for dental care in cases involving autism spectrum–related sensory and communication characteristics, Down syndrome, cerebral palsy, developmental or cognitive differences and certain conditions that affect movement control.

However, having special healthcare needs is not, on its own, an indication for general anesthesia.

Some individuals can be treated under local anesthesia with appropriate communication and environmental adjustments. For some, shorter appointments or sedation may be considered, while general anesthesia may be considered in selected patients whose necessary procedures cannot be carried out by other methods.

The core approach here is not to assign an anesthesia method automatically based on diagnosis, but to choose a feasible treatment method according to the person's needs and clinical condition.

Which Dental Treatments Can Be Performed Under General Anesthesia?

The dental procedures that can be carried out under general anesthesia vary according to the patient's needs.

Fillings and restorative procedures, root canal or pulp treatment on suitable teeth, tooth extractions, gum treatment and some surgical procedures can be planned under general anesthesia. In clinically suitable patients, implant surgery may also be considered within this scope.

However, placing implants, performing bone grafting or extracting several teeth does not in itself require general anesthesia. Many of these procedures can be carried out under local anesthesia in suitable patients.

In addition, the use of general anesthesia does not mean that all treatment will necessarily be completed in the same session.

The aim is not to perform as many procedures as possible, but to carry out clinically necessary treatment to an extent appropriate to the patient's condition.

What Are the Advantages of General Anesthesia?

The “advantages” of general anesthesia are not the same for every patient, and the method should not be regarded as a comfort option.

In some patients for whom standard dental treatment cannot be carried out, general anesthesia may make it possible to perform the necessary dental procedures.

For example, this method may be considered for some patients who cannot continue treatment because of severe dental anxiety, who have marked difficulty with movement control, or who cannot tolerate procedures inside the mouth because of a strong gag reflex.

In suitable patients, more than one dental procedure can be planned for the same session. However, general anesthesia does not automatically increase treatment success, does not necessarily prevent psychological trauma and does not guarantee that all procedures will be completed in a single session.

The anesthesia method and the long-term success of a dental procedure are separate matters. The outcome of dental treatment is affected by many factors, such as the quality of the procedure, biological healing, oral care and regular check-ups.

Is General Anesthesia Safe?

General anesthesia is widely used in modern medicine, but it is not completely risk-free.

Patient assessment, appropriate anesthesia planning, monitoring throughout the procedure and the availability of necessary intervention facilities play an important role in managing risks.

After anesthesia, some people may experience nausea, vomiting, shivering, drowsiness or throat discomfort. Other and more serious complications are also medically possible.

The level of risk is not the same for everyone. General health, age, coexisting conditions, airway characteristics and the extent of the procedure can affect individual risk. In its current patient information, the Royal College of Anaesthetists also emphasizes that the risks associated with general anesthesia can differ between individuals and that each person should discuss their own risks with an anesthesiologist.

For this reason, neither of the two extreme statements, “general anesthesia is extremely safe” or “general anesthesia is very dangerous”, can replace an individual risk assessment.

What Is the Difference Between General Anesthesia and Sedation?

Sedation and general anesthesia are not the same procedure.

Sedation can be given at a light, moderate or deep level. Under light and moderate sedation, the patient can usually respond to verbal instructions. Under deep sedation, responses may be reduced and airway or breathing support may be needed.

General anesthesia, on the other hand, involves controlled unconsciousness.

With either method, local anesthesia may also be given separately for pain control during the dental procedure.

For this reason, the choice of method should not be based on questions such as “which is stronger?” or “which is better?”. The patient's medical characteristics, ability to cooperate with treatment and the extent of the dental procedures should be assessed together.

What Happens After General Anesthesia?

Once dental treatment is complete, the anesthesia is stopped and the patient is monitored in the recovery area.

The patient's level of consciousness, airway, breathing, circulation and general clinical condition are assessed. Necessary follow-up is provided for pain, nausea or other complaints.

In suitable patients, same-day discharge may be considered after the necessary observation and clinical assessment. However, it cannot be guaranteed in advance that every patient will be discharged on the same day.

After discharge, the individual advice given on eating and drinking, medications, oral care, physical activity and being accompanied should be followed.

Regular dental check-ups remain important after dental treatment under general anesthesia as well. General anesthesia is not a treatment that prevents new tooth decay or gum disease from developing in the future.

Conclusion

Dental treatment under general anesthesia is one of the medical options that may be considered for some patients in whom it is difficult to carry out the necessary procedures using standard dental methods.

Severe dental fear, a strong gag reflex, difficulty cooperating with treatment, certain special healthcare needs or the need for extensive dental treatment may lead to general anesthesia being considered. However, the presence of these conditions does not, on its own, mean that general anesthesia must be used.

Alternatives such as local anesthesia, communication and behavior guidance techniques and, in suitable patients, sedation should also be considered.

While the dentist determines the patient's dental treatment needs, the Specialist in Anesthesiology and Reanimation carries out the patient's anesthesia assessment and anesthesia management.

The core approach in general anesthesia is not simply to put the patient “to sleep”, but to plan the entire process, from the pre-procedure assessment through anesthesia management to post-procedure recovery, according to the patient's medical characteristics.

This article has been prepared for general information purposes. Decisions about general anesthesia, sedation or dental treatment should be planned individually by the relevant healthcare professionals based on the person's medical and dental assessment.
