Dental Treatment Under General Anesthesia

Dental Treatment Under General Anesthesia

Most dental treatments can be carried out under local anesthesia while the patient is awake . However, in some children and adults, severe fear of the dentist, a strong gag reflex, difficulty cooperating with treatment, special healthcare needs or the need for extensive dental treatment can make it difficult to continue treatment in a standard dental chair. In these situations, different approaches may be considered depending on the patient's individual characteristics. Dental treatment under general anesthesia is one of these options.

General anesthesia, often referred to informally as “sleep dentistry” , is not necessary or suitable for every patient. When planning treatment, alternatives are considered first, such as local anesthesia, communication and behavior guidance techniques, dividing treatment into shorter sessions and, for suitable patients, sedation.

The decision to use general anesthesia is not based solely on the number of dental procedures required. The patient's age, general health, ability to cooperate with treatment, the scope of the planned procedures and the feasibility of alternative methods should all be evaluated together. Current pediatric dentistry guidance also recommends that behavior guidance techniques be tailored to the individual, particularly in children, and that sedation and general anesthesia be regarded as advanced options that require careful evaluation. (AAPD)

What Is General Anesthesia?

General anesthesia is a controlled state of unconsciousness induced with medications and reversed when their administration is stopped. During the procedure, the patient is not aware of what is happening around them.

General anesthesia does not simply mean “putting the patient to sleep.” A major part of the anesthesia process involves assessing and managing the airway, breathing, circulation and other essential vital functions.

The anesthetic medications and the technique used are determined by factors such as the patient's age, weight, existing medical conditions, current medications, airway characteristics and the scope of the planned procedures.

While the dentist carries out the oral and dental treatment, the Specialist in Anesthesiology and Reanimation is responsible for the patient's anesthesia assessment and anesthesia management. Dental treatment under general anesthesia is therefore a multidisciplinary process in which dental treatment and anesthesia management take place simultaneously.

Who May Be Considered for Dental Treatment Under General Anesthesia?

The need for general anesthesia varies from person to person. Being afraid of the dentist or needing more than one dental treatment does not, on its own, mean that general anesthesia will be used.

Nevertheless, general anesthesia may become an option in certain situations.

Some patients with severe dental anxiety or dental phobia may have difficulty sitting in the dental chair, keeping their mouth open long enough or continuing with treatment. When short appointments, adjustments in communication and, where appropriate, sedation are not sufficient, general anesthesia may additionally be considered.

Some people with a strong gag reflex may be unable to tolerate an impression tray, an X-ray sensor or dental instruments being placed in the mouth. For suitable patients in whom necessary dental procedures cannot be performed under standard conditions because of gagging, nausea or vomiting, different anesthesia options may be considered.

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

In some patients, the need for extensive dental treatment may be combined with difficulty cooperating with treatment. In such cases, dividing treatment into separate sessions, sedation or general anesthesia are evaluated on an individual basis.

General Anesthesia for Children's Dental Treatment

When planning dental treatment for children, clinicians consider not only the number of cavities but also the child's age, developmental stage, dental treatment needs, the presence of pain or infection and their capacity to cooperate with treatment.

Young children in particular may not always be able to understand a lengthy dental procedure, keep their mouth open for a long time or stay still. On the other hand, many children can gradually adapt to dental treatment with appropriate communication and behavior guidance techniques.

For this reason, general anesthesia is not necessary for every anxious child or for every child with multiple cavities.

The approaches that can be used in children are considered in a stepwise manner, from simple to more advanced methods. Familiarization with the clinical environment, explanation, behavior guidance and local anesthesia may be sufficient for some children. Sedation may be considered for suitable patients. In some children for whom the necessary treatment cannot be carried out with these methods, or who have other clinical needs, general anesthesia may become an option.

The AAPD's current approach also recommends evaluating the child's medical history, developmental characteristics, previous treatment experiences, the urgency of treatment and alternative methods together. (AAPD)

General Anesthesia for Patients with Special Healthcare Needs

Dental treatment for patients with special healthcare needs should be planned on an individual basis.

Additional adjustments may be needed during dental treatment for individuals with sensory characteristics associated with the autism spectrum, Down syndrome, developmental or cognitive differences, difficulties with movement control or different communication needs.

However, two people with the same diagnosis will not necessarily have the same dental treatment needs or respond to treatment in the same way.

Some individuals can be treated under local anesthesia, while others may need shorter appointments or adjustments to the environment. Sedation may be considered for some patients. In selected cases where the necessary dental procedures cannot be carried out despite other methods, general anesthesia may be an option.

The core approach is not to plan general anesthesia directly on the basis of a person's diagnosis, but to determine a feasible method according to the individual's needs and a clinical evaluation.

Fear of the Dentist and General Anesthesia

For some people, fear of the dentist takes the form of mild anxiety, while for others it can be severe enough to cause them to postpone treatment altogether.

Negative past experiences, fear of needles, worry about pain, the sound of dental equipment or a feeling of losing control during treatment can all increase dental anxiety.

In such cases, general anesthesia is not always the first approach. It is important to understand which stage of treatment the patient fears and to create a plan accordingly.

For a patient with fear of the dentist, treatment can be planned using options such as communication, short appointments, gradual desensitization, local anesthesia and, where appropriate, sedation. General anesthesia may additionally be considered for some patients in whom the necessary treatment cannot be carried out with these methods.

What If a Strong Gag Reflex Prevents Dental Treatment?

Some patients report that they cannot tolerate an impression tray in their mouth, cannot bear an X-ray sensor or gag intensely when dental instruments approach the back of the mouth.

Although this is often informally described as “nausea reflex” , in most cases it is actually a strong gag reflex.

First, the procedures that trigger the reflex can be identified. Methods such as smaller dental instruments, shorter working intervals, adequate suction or, for some treatments, digital impressions may help.

Sedation may be considered for suitable patients in whom anxiety markedly intensifies the gag reflex.

For some patients in whom the necessary dental treatment cannot be carried out by other methods because of gagging, nausea or vomiting, dental treatment under general anesthesia may be considered as an alternative.

It should also be understood that general anesthesia does not permanently treat the underlying cause of the gag reflex.

How Is a Patient Evaluated Before General Anesthesia?

One of the key stages of the general anesthesia process is the pre-procedure medical evaluation.

The Specialist in Anesthesiology and Reanimation evaluates the patient's existing medical conditions, regular medications, allergies, previous surgery and anesthesia experiences, and airway characteristics.

Any significant event during a previous anesthetic must be reported. In addition to regularly used prescription medications, information should also be provided, where relevant, about over-the-counter products and supplements.

Not every patient needs the same tests. The need for tests is determined by the patient's health status and the planned procedure.

For children, it is also important to inform the anesthesia team before the procedure about recent changes such as a febrile illness, cough or respiratory tract infection.

The Royal College of Anaesthetists also emphasizes the importance of discussing the person's health status, medications, previous anesthesia experiences and anesthesia options with the patient before anesthesia. (The Royal College of Anaesthetists)

Why Is Fasting Important Before General Anesthesia?

Before general anesthesia, the patient is given specific instructions about eating and drinking.

This period may not be the same for everyone. The type of food or fluid, the patient's age and their medical condition can all affect the preparation plan.

Therefore, the individual instructions given by the anesthesia team should be followed rather than general fasting times found on the internet.

Regular medications should also not be stopped or have their doses changed without a physician's advice.

If the preparation instructions cannot be followed, the healthcare team should be informed.

How Is Dental Treatment Under General Anesthesia Performed?

On the day of the procedure, the patient's identity, health information, preparation status, dental treatment plan and required consents are checked first.

Once anesthesia has been induced, monitoring appropriate to the patient's clinical condition is carried out. Heart rhythm, blood pressure, oxygenation, breathing and other necessary physiological parameters are assessed throughout the procedure.

While the anesthesia team continues to manage the patient's anesthesia and vital functions, the dentist carries out the planned dental procedures.

During treatment, new findings in the mouth that could not be assessed beforehand may emerge. For this reason, some parts of the dental plan may be reassessed according to the clinical findings.

Once the procedures are complete, the anesthesia is discontinued and the patient is monitored during the recovery period.

Which Dental Treatments Can Be Performed Under General Anesthesia?

Depending on the patient's needs, various dental treatments may be planned under general anesthesia.

These may include fillings and restorative treatments, root canal or pulp treatments on suitable teeth, tooth extractions, necessary surgical procedures, periodontal treatments and, in suitable patients, implant surgery.

However, the use of general anesthesia does not mean that all teeth will be extracted or that all procedures will necessarily be carried out in the same session.

Teeth that can be preserved should be evaluated according to their clinical condition.

Implant or prosthetic treatments may also require separate appointments for healing, impressions, try-ins and prosthetic stages.

Can All Dental Treatment Be Completed in a Single Session?

Under general anesthesia, in suitable patients, more than one dental procedure may be planned in the same session.

This approach may form part of the treatment plan, particularly for people who find it difficult to cope with repeated appointments.

However, it cannot be guaranteed that all treatment will be completed in a single session.

The scope of surgical procedures, the patient's general condition, the length of the procedure and treatments that require healing time must all be taken into account.

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

Are General Anesthesia and Sedation the Same Thing?

No.

Sedation and general anesthesia are different procedures.

During sedation, the patient's anxiety and awareness of their surroundings are reduced. Depending on the level of sedation, the patient may be able to respond to verbal instructions.

General anesthesia, on the other hand, involves a controlled loss of consciousness.

Sedation and general anesthesia are also not substitutes for local anesthesia. When dental pain control is needed, local anesthesia may be administered in addition.

The choice of method should be based not on the question “which is better?” but on the question “which approach is more appropriate for this patient and the treatment to be performed?” .

Does General Anesthesia Carry Risks?

General anesthesia is a medical procedure and cannot be described as completely risk-free.

The level of risk is not the same for everyone. The patient's age, general health, coexisting conditions, medications, airway characteristics and the scope of the procedure can all influence the evaluation.

After anesthesia, some patients may experience temporary effects such as nausea, drowsiness, shivering or throat discomfort.

More serious complications are also medically possible. It is therefore not appropriate for a person to judge their own risk based on other patients' experiences or on general information found online alone.

Individual anesthesia risks should be evaluated before the procedure by a Specialist in Anesthesiology and Reanimation.

What Happens After General Anesthesia?

Once dental treatment is complete, the anesthetic medications are discontinued and the patient enters a controlled recovery process.

During this period, the patient's level of consciousness, breathing, circulation and general condition are monitored.

In suitable patients, following the necessary observation and clinical assessment, same-day discharge may be considered. Some patients may require longer observation.

After discharge, the personalized recommendations given regarding eating and drinking, medications, oral care and physical activity should be followed.

For children, supervision by a responsible adult after the procedure is important.

What Questions Can Be Asked When Deciding on General Anesthesia?

During the evaluation, patients or families may discuss the following topics with the healthcare team:

Why is general anesthesia being considered?
Could the treatment be done under local anesthesia or sedation?
Which dental treatments are planned?
Is it expected that all procedures will be done in the same session?
What are the individual anesthesia risks?
What preparations need to be made before the procedure?
What kind of follow-up will be needed after treatment?

Discussing these questions openly can help patients and their families better understand the treatment process.

Conclusion

Dental treatment under general anesthesia is one of the options that may be considered for some children and adults in whom the necessary treatment is difficult to carry out under standard dental conditions.

Severe fear of the dentist, 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 any one of these on its own does not mean that general anesthesia will be used.

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

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

The core approach is not to steer the patient toward a particular anesthesia method, but to create an individualized treatment plan by evaluating dental needs, general health, ability to cooperate with treatment and the available alternatives together.

This article has been prepared for general information purposes. Decisions about general anesthesia, sedation or dental treatment should be made on an individual basis by the relevant healthcare professionals following the person's medical and dental evaluation.
