What Is Sleep Dentistry?

What You Need to Know About Dental Treatment Under Sedation and General Anesthesia

“Sleep dentistry” is an everyday expression used to describe dental treatment carried out with the support of sedation or general anesthesia. From a medical perspective, however, sedation and general anesthesia are not the same procedure. The patient's level of consciousness, how their breathing is managed, the medications used and the monitoring required throughout the procedure can vary depending on the method.

Most dental treatments can be carried out under local anesthesia while the patient is awake. Nevertheless, different approaches may be considered because of severe dental anxiety, difficulty cooperating with treatment, a severe gag reflex, certain special healthcare needs or extensive dental procedures.

At this point, the real question is not “Should the patient be put to sleep?”; rather, “Which method is more appropriate for this person's dental needs and general health?” is the question that should be asked.

The decision on sleep dentistry is shaped by considering the dentist's treatment plan together with the anesthesiologist's medical evaluation.

Is Sleep Dentistry Sedation or General Anesthesia?

One of the things patients most often confuse is the difference between sedation and general anesthesia.

Sedation is a medication-based method used to reduce a person's anxiety, help them relax and make it easier for them to cooperate with the dental procedure. Sedation can be mild, moderate or deeper. The level of consciousness and of communication with the surroundings varies with the depth of sedation administered.

For this reason, it is not always correct to say that “the patient is completely asleep” under sedation.

Under general anesthesia, by contrast, the patient is unconscious and unaware of their surroundings during the procedure. The anesthesiologist monitors breathing, circulation and other vital functions and provides airway and breathing support when needed. During general anesthesia, physiological parameters such as heart rate, blood pressure, breathing and oxygenation are monitored.

So although both procedures are commonly referred to as “sleep dentistry,” it is important to understand clearly which method will be used.

Who May Be Considered for Sleep Dentistry?

Not everyone who has dental anxiety or is scheduled for lengthy dental treatment needs sedation or general anesthesia.

For some patients, communicating with the dentist, dividing treatment into stages, behavior guidance techniques and local anesthesia may be sufficient.

Nevertheless, in people with severe dental anxiety, sedation or general anesthesia options may be considered in some situations where treatment cannot be carried out in the dental chair.

Similarly, a severe gag reflex can make intraoral procedures considerably more difficult for some patients. Here too, different methods may be considered depending on the severity of the gag reflex and the nature of the planned treatment.

In patients with special healthcare needs, communication, movement control or sensory sensitivities may affect treatment planning. However, having special healthcare needs does not, on its own, mean that general anesthesia is required.

The approach is similar for children. Age, developmental stage, the scope of treatment needs, previous experiences and other available behavior guidance options should be evaluated together. Current pediatric dentistry guidelines also regard sedation and general anesthesia as more advanced behavior guidance methods and recommend that the decision be made following an evaluation specific to the child .

Is General Anesthesia Necessary If You Have Dental Phobia?

The degree of dental anxiety varies from person to person.

Some patients feel apprehensive only before a procedure, while others may experience marked anxiety at the mere thought of dental treatment. More severe dental fear can make it difficult for the patient to cooperate with an examination or treatment.

However, the presence of dental fear is not, on its own, an indication for general anesthesia.

First, the degree of fear, the treatment required, the patient's past experiences and whether treatment could be carried out with simpler methods are evaluated.

Some patients can cope with treatment through detailed explanation and short sessions. For others, sedation options may be considered. In different clinical circumstances, general anesthesia may become an option.

The aim, therefore, is not to put the patient to sleep in order to “eliminate” the fear, but to determine the appropriate approach by assessing how the person can tolerate treatment.

Is General Anesthesia Necessary for Lengthy Dental Treatments?

Implant procedures, surgical procedures or full-mouth rehabilitation can sometimes take a long time. However, a long procedure does not, on its own, mean that general anesthesia is required.

Many lengthy dental procedures can be carried out under local anesthesia.

When considering general anesthesia or sedation, the patient's general health, anxiety level, ability to stay still, the nature of the procedures to be performed and the patient's preference, as well as the length of treatment, may be taken into account.

In some cases, several procedures may be planned for the same session. However, the purpose of general anesthesia is not to perform as many procedures as possible.

From a dental perspective, the main goal is to plan the treatment that is genuinely necessary in an appropriate way.

How Do You Prepare for Sleep Dentistry?

If sedation or general anesthesia is being considered, it is important to evaluate the patient's medical history before the procedure.

The anesthesiologist may ask about the patient's existing medical conditions, regular medications, known allergies and previous experiences with surgery or anesthesia.

Cardiovascular disease, respiratory disease, diabetes, hypertension, sleep apnea and certain neurological conditions are among the health problems that may be taken into account in anesthesia planning. However, having one of these does not automatically mean that general anesthesia cannot be performed; an individual risk assessment is required.

It may also not be necessary to request the same blood tests or investigations from every patient. The necessary investigations can be determined according to the patient's health status and the planned procedure.

Why Do You Need to Fast Before General Anesthesia?

There are specific rules about eating and drinking before general anesthesia and some forms of sedation.

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

However, it is not appropriate for patients to set their own fasting period. The instructions given may differ depending on the anesthesia method and the patient's age and health status.

For this reason, the eating and drinking instructions given by the anesthesia team must be followed before the procedure.

If the patient has accidentally eaten or drunk anything within the recommended period, it is important to let the healthcare team know.

How Is Sleep Dentistry Performed?

On the day of treatment, the patient's information and the planned procedures are reviewed first.

If general anesthesia is to be used, the anesthesiologist administers the necessary medications and the patient becomes unconscious. During this process, the patient's physiological functions are monitored by the anesthesia team.

The dentist, in turn, carries out the previously prepared dental treatment plan.

The responsibilities of the anesthesiologist and the dentist are distinct: the anesthesiologist is responsible for anesthesia management and monitoring vital functions, while the dentist carries out the oral and dental treatment.

In some cases, a condition that could not be seen during the pre-procedure examination may become apparent after a more detailed assessment during treatment. In such situations, the dental treatment plan may need to be reassessed.

How Is the Patient Monitored During Anesthesia?

Monitoring is one of the fundamental elements of any anesthesia procedure.

During general anesthesia, vital parameters such as heart rate and rhythm, blood pressure, oxygenation and breathing are monitored. The monitoring methods used may be expanded depending on the patient's condition and the anesthesia method.

The setting in which the procedure is performed must also be appropriate for the planned type of anesthesia. In addition to the equipment needed for anesthesia and airway management, it is important to have equipment for managing unexpected situations and a suitable post-anesthesia monitoring area.

Safety does not depend on a single device or a single person; patient assessment, the team, monitoring, the setting and post-procedure follow-up are all considered together.

Is General Anesthesia Safe?

It would not be correct to give a single “yes” or “no” answer that applies to everyone when patients ask, “Is sleep dentistry safe?”

Every anesthesia procedure carries certain risks, and the level of individual risk can vary.

Age, existing health problems, medications and the characteristics of the procedure to be performed all play a role in the risk assessment.

After general anesthesia, some people may experience temporary effects such as nausea, vomiting, shivering, drowsiness or throat discomfort . More serious complications are also medically possible, but individual likelihoods differ depending on the patient's characteristics.

This is why the pre-procedure consultation with the anesthesiologist is important. It is helpful for patients to ask during this consultation about the risks that are relevant to them and the possible alternatives.

What Happens After Sleep Dentistry?

Once the dental procedures are complete, the general anesthesia is discontinued and the patient begins to wake up.

During this period, the level of consciousness, breathing and circulation are monitored. Some people come round quickly, while in others temporary drowsiness or grogginess may last longer.

The time of discharge may not be the same for every patient. It is decided according to the anesthesia method used, the dental treatment performed and the patient's general condition.

After general anesthesia or some forms of sedation, the instructions given by the anesthesia team regarding driving, going home alone and when to resume daily activities should be followed. It has been reported that reflexes and decision-making ability may be affected for a period after general anesthesia.

Sedation or General Anesthesia: Which Is More Appropriate?

It is not appropriate to compare these two methods in terms of “which is better?”

For some patients, local anesthesia is sufficient. For others, sedation can make it easier to cooperate with treatment. In different dental and medical circumstances, dental treatment under general anesthesia may be considered.

The most appropriate method is determined by evaluating the patient's general health, age, the scope of treatment, anxiety level, ability to cooperate and the feasibility of alternative methods together.

It may be helpful for the patient or their family to get answers to the following questions before making a decision: Why is sedation or general anesthesia being considered? Is treatment possible under local anesthesia? Which procedures are planned? What are the individual anesthesia risks? What will the post-procedure process involve?

Conclusion

Sleep dentistry is a general expression commonly used to describe dental procedures carried out with the support of sedation and general anesthesia. Medically, however, these methods are different from each other and are not applied in the same way to every patient.

A large proportion of dental treatments can be carried out under local anesthesia. In some clinical situations where this is not sufficient or is difficult to apply, sedation or general anesthesia options may be considered.

In the decision-making process, the necessity of dental treatment, the patient's general health, their level of anxiety and cooperation, alternative methods and the individual risks related to anesthesia should all be considered together.

While the dentist evaluates the scope of the dental treatment to be performed, the anesthesiologist evaluates the anesthesia method and the patient's specific medical conditions. In this way, the treatment plan can be tailored to the individual.

Therefore, questions such as “Is sleep dentistry safe?” or “Is general anesthesia right for me?” should be answered not just on the basis of general information, but following an individual dental and anesthesia evaluation.

This article has been prepared for general information purposes. Decisions on sedation, general anesthesia or dental treatment should be evaluated individually by the relevant healthcare professionals according to the person's health status and treatment needs.
