Dental Treatment Under General Anesthesia

Is Dental Treatment Under General Anesthesia Safe?

What You Need to Know, From an Anesthesiologist’s Perspective

When it comes to dental treatment, the main problem for some people is not so much pain as fear of the dentist, a sense of losing control, or difficulty cooperating with treatment. Previous negative dental experiences, fear of needles, the sound of dental instruments, a severe gag reflex or the thought of a lengthy procedure can lead some patients to postpone their dental treatment.

Postponing treatment for a long time can allow existing tooth and gum problems to progress and, over time, lead to the need for more extensive treatment. For this reason, it is important to consider dental anxiety as part of the treatment plan as well.

The popular term “sleep dentistry” may be used for both sedation and general anesthesia. However, the two are not medically the same. With sedation, the patient’s level of consciousness varies depending on how deep the sedation is, whereas general anesthesia uses medication to produce a controlled loss of consciousness.

That is why there is no single answer to the question “Is sleep dentistry safe?” that applies to every patient. Anesthesia-related risk should be assessed according to the patient’s general health, the method to be used, the procedures to be performed and individual characteristics. General anesthesia and sedation are not completely risk-free; however, appropriate patient assessment, the necessary medical equipment, monitoring throughout the procedure and follow-up by the anesthesia team play a key role in managing these risks. The Royal College of Anaesthetists also states that the risks of general anesthesia can vary from person to person and that each person’s own risks should be discussed with an anesthesiologist.

What Is “Sleep Dentistry”?

“Sleep dentistry” is not the name of a medical procedure. Patients mostly use this expression to describe dental treatment carried out under sedation or general anesthesia .

Sedation can reduce the patient’s anxiety and awareness of their surroundings. Under mild 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.

Under general anesthesia, the patient is unconscious and is not aware of what is happening around them during the procedure. The anesthesia team manages the anesthesia by monitoring the patient’s airway, breathing, circulation and other necessary physiological parameters.

Sedation and general anesthesia also do not replace pain control. Where needed during dental procedures, local anesthesia may additionally be used to numb the teeth and surrounding tissues.

Therefore, a patient saying “I want to be asleep” does not by itself determine which method will be used. The difficulty the patient is experiencing, the scope of the dental treatment and their medical condition must be assessed first.

The Most Important Stage for an Anesthesiologist: Pre-Procedure Assessment

From the standpoint of general anesthesia, the safety approach does not begin in the operating room. A major part of the anesthesia process is the proper assessment of the patient before the procedure.

The Specialist in Anesthesiology and Reanimation reviews the patient’s existing medical conditions, current medications, known allergies, previous surgeries and past experiences with anesthesia.

In particular, if a difficult airway, severe nausea and vomiting, an allergic reaction or any other significant problem occurred during a previous anesthetic, this must be shared.

Heart, lung or other systemic conditions, the medications being used and the scope of the planned dental procedure can all affect the anesthesia plan.

Not every patient needs the same tests. Blood tests or consultations with other specialties are planned according to the individual’s medical condition.

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

How Is the Patient Monitored During General Anesthesia?

General anesthesia does not simply mean putting the patient to sleep.

Throughout the procedure, the anesthesia team monitors the patient’s heart rhythm, blood pressure, oxygenation, breathing and other necessary physiological parameters . The depth of anesthesia and the medications used are also managed according to the patient’s clinical condition.

Because relaxation of the muscles around the throat and chest during general anesthesia can affect breathing, airway management is one of the fundamental elements of anesthesia. The appropriate airway technique for each patient is determined by the anesthesia team. The Royal College of Anaesthetists states that keeping the airway open and providing breathing support when necessary during general anesthesia are among the core components of anesthetic management.

Meanwhile, the dentist carries out the planned dental treatment during the same session.

The dentist is responsible for the dental treatment, while the Specialist in Anesthesiology and Reanimation is responsible for assessing and managing the anesthesia.

This division of roles is particularly important in dental procedures, because the anesthesia team and the dentist work simultaneously in the same anatomical area — around the mouth and airway.

Who May Be Considered for Dental Treatment Under Sedation or General Anesthesia?

General anesthesia or sedation is not necessary for every dental patient.

A large proportion of dental procedures can be carried out under local anesthesia. Nevertheless, different methods may need to be considered for some patients.

For people with intense fear of the dentist, the first step may be to assess whether treatment is possible with approaches such as communication, short appointments, gradual familiarization or local anesthesia. For some patients for whom these are not sufficient, sedation or general anesthesia may be considered.

People with a severe gag reflexmay not be able to tolerate dental instruments, impression trays or X-ray sensors being placed in the mouth. If necessary treatment cannot be carried out because of gagging, nausea or vomiting, anesthesia options may be considered in suitable patients.

In patients with special healthcare needs, difficulties related to communication, sensory sensitivity or movement control can make dental treatment more challenging. However, having special needs does not in itself mean that general anesthesia is required.

The anesthesia approach may also be considered separately for some people who need extensive dental treatment and have difficulty tolerating long procedures.

Is Dental Treatment Under General Anesthesia Safe for Children?

The decision to use general anesthesia in children requires particularly careful and individual assessment.

Being young or having many cavities is not in itself a reason for general anesthesia. The child’s age, developmental level, oral and dental health needs, the urgency of treatment, general health and response to behavior management techniques are all considered together.

Some children can have their dental treatment under local anesthesia with the help of familiarization with the clinical environment, communication and appropriate behavior management techniques.

However, for some children who need extensive dental treatment and in whom the necessary procedures cannot be carried out despite appropriate approaches, general anesthesia may be considered as an option.

That is why it is not right to answer parents’ question “Is general anesthesia safe for my child?” based only on the child’s age. The child’s medical condition and the planned treatment must be assessed.

General Anesthesia for Patients with Special Healthcare Needs

Some individuals with autism spectrum characteristics, Down syndrome, cerebral palsy, developmental or cognitive differences, or difficulties with movement control may need additional arrangements for dental treatment to be carried out.

However, having a diagnosis does not in itself constitute an indication for general anesthesia.

Some patients with special healthcare needs can be treated comfortably under local anesthesia. For others, shorter appointments, sensory adaptations or different communication methods may be sufficient. Sedation may be considered in suitable patients.

For some individuals in whom the necessary dental treatment cannot be carried out with these methods, general anesthesia may be one of the options.

In anesthesia services for special care dentistry, close collaboration between the dental team and the anesthesia team, communication adapted to the person’s needs, and perioperative care are important.

General Anesthesia for a Severe Gag Reflex

Some patients may experience marked gagging not only when impressions are taken but even when a simple dental instrument is placed in the mouth.

First, the factors that trigger the reflex need to be understood and simpler methods considered. Appropriately sized dental instruments, short working periods, effective suction, dividing treatment into stages or, in some cases, digital impressions may help.

Sedation may be considered for some patients with significant anxiety.

For suitable patients in whom necessary dental treatment cannot be carried out because of a severe gag reflex, general anesthesia may also be one of the options.

However, general anesthesia does not permanently treat the cause of the gag reflex. The patient may experience similar sensitivity at later check-ups or when wearing dentures.

Is General Anesthesia Required for Extensive Implant or Surgical Procedures?

Having multiple dental implants placed, or planning bone grafting or tooth extractions, does not in itself mean that general anesthesia is required.

A large proportion of these procedures can be performed under local anesthesia in suitable patients.

Nevertheless, sedation or general anesthesia may be considered for some patients who are scheduled for extensive surgery and who also have intense dental anxiety, marked difficulty cooperating with treatment or other clinical needs.

The use of general anesthesia does not guarantee that implants will be more successful or that surgical procedures will necessarily be completed in a single session.

The anesthesia method and the success of surgical treatment are separate matters.

Can All Dental Treatment Be Done in a Single Session?

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

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

Dental implant treatment, prosthetic work, some root canal treatments or surgical procedures that require healing may need separate appointments.

In addition, new dental findings made during the procedure may require changes to the treatment plan prepared in advance.

The aim is not to carry out as many procedures as possible, but to plan the necessary treatment within a scope appropriate to the patient’s medical and dental condition.

What Are the Risks of General Anesthesia?

General anesthesia is not completely risk-free.

After anesthesia, some patients may experience nausea, vomiting, throat discomfort, shivering or drowsiness . How likely these are can vary depending on the patient and the anesthesia method used.

More serious complications are also medically possible. The patient’s coexisting conditions, age, airway characteristics and the scope of the procedure can affect their individual level of risk. The RCoA also notes that an individual’s risks of general anesthesia may be higher or lower than the average figures.

Therefore, the fact that another patient had anesthesia without problems does not indicate your own risk. Likewise, a single negative experience read on the internet does not mean that you are at high risk from anesthesia.

An individual risk assessment should be carried out by a Specialist in Anesthesiology and Reanimation.

Why Is Fasting Important Before General Anesthesia?

Before general anesthesia, the patient is told when to stop eating and drinking.

The purpose of these instructions is to reduce the risk associated with stomach contents entering the airway during anesthesia.

Fasting times may vary depending on the type of food and fluid and on the patient’s characteristics.

For this reason, the individual instructions given by the anesthesia team should be followed rather than general timings found on the internet.

Regularly used medications should also not be stopped, nor their doses changed, without consulting a doctor.

Will I Be in Pain When I Wake Up?

Having general anesthesia does not mean there will be no pain or swelling at all after dental surgery.

Local anesthesia and other pain control methods may be used during the procedure where needed. Pain management after the procedure is planned according to the scope of the dental procedure performed and the patient’s health.

Recovery after more limited procedures such as fillings is not the same as recovery after multiple extractions, implants or bone surgery.

For this reason, the pain, swelling and recovery to be expected after the procedure should be explained to the patient according to the dental treatment to be performed.

Can I Go Home the Same Day After General Anesthesia?

For some suitable patients, after the necessary observation and clinical assessment, same-day discharge may be considered.

However, discharge does not happen automatically once a certain amount of time has passed. The patient’s level of consciousness, breathing and circulation, symptoms such as nausea or pain, and the procedures performed are all assessed together.

Some patients may need a longer period of observation.

After discharge, the instructions given by the anesthesia and dental teams regarding having a companion, eating and drinking, taking medication, driving and returning to daily activities should be followed.

Conclusion: Is Dental Treatment Under General Anesthesia Safe?

Sedation and general anesthesia, popularly referred to as sleep dentistry, are medical methods that may be considered for suitable patients; however, they are not completely risk-free.

It is not medically accurate to describe general anesthesia either as “a very dangerous method” or as “just a simple sleep.”

The core approach to anesthesia involves assessing the patient before the procedure, choosing the appropriate method, providing the necessary medical equipment and monitoring, maintaining anesthetic management throughout the procedure, and observing the patient until they have recovered sufficiently.

Fear of the dentist, a severe gag reflex, certain difficulties encountered by patients with special healthcare needs, or the need for extensive dental treatment may lead to general anesthesia being considered. However, none of these situations on its own means that general anesthesia is mandatory.

While the dentist plans the necessary dental treatment, the Specialist in Anesthesiology and Reanimation assesses the patient from an anesthesia perspective and manages the anesthesia.

So rather than asking “Is general anesthesia safe?”, a more appropriate approach is to consider the question “Which anesthesia method may be suitable for my health condition and the dental treatment to be performed, and what are my individual risks?”

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