Short answer: Sedation is a controlled state of relaxation created with calming medications to reduce the patient's anxiety and make them more comfortable during dental treatment. Under conscious sedation the patient breathes on their own and can respond when spoken to; under general anesthesia consciousness is completely switched off. Sedation is used together with local anesthesia, and suitability is determined after a health assessment.
Sitting in the dentist's chair is a serious source of anxiety for some people. This anxiety can lead to necessary treatment being postponed for years and small problems growing larger. Sedation in dental treatment is one of the methods used in such cases to help the patient undergo treatment in a calmer and more comfortable way. In this article we look at what sedation is, its types, how it differs from general anesthesia, who it is suitable for, preparation before the procedure and safety issues.
What is sedation?
Sedation is a controlled state of consciousness in which, with the help of calming medications, the patient's anxiety is reduced, they relax and they cooperate with treatment more comfortably. A patient under sedation is usually in a calm and relaxed state somewhere between sleep and wakefulness. Many patients remember little or none of most of the procedure afterwards.
It is important to know that sedation does not eliminate pain on its own. Pain control during dental treatment is provided by local anesthesia, which is given together with sedation. Sedation helps the patient tolerate the local anesthetic injection and the treatment itself more comfortably. For this reason, sedation does not replace local anesthesia but complements it.
What are the types of sedation?
Sedation is divided into different types according to its depth and route of administration. Which type is chosen depends on the patient's level of anxiety, the length and scope of the procedure, their general health and the dentist's assessment.
- Minimal sedation: The patient is fully awake but more relaxed and calm. It is usually preferred for patients with mild anxiety.
- Conscious (moderate) sedation: This is the most commonly used type of sedation in dentistry. The patient is relaxed and drowsy, breathes on their own and can respond when spoken to or lightly touched. It is usually achieved with medications given intravenously, and its effect can be adjusted throughout the procedure.
- Inhalation sedation: It is given by breathing in a calming gas mixed with oxygen through a mask. Its effect starts quickly and wears off shortly after the mask is removed. It can be used especially in children and in mild to moderate anxiety.
- Oral sedatives: In some cases the aim is to reduce anxiety with a medication prescribed by the doctor and taken before the procedure. Because the onset time and depth of the effect vary from person to person, control is more limited than with the intravenous route.
- Deep sedation: This is a deeper state in which the patient cannot be easily woken, and it has features close to general anesthesia. It is only carried out under suitable conditions and with a specialist team.
Intravenous sedation and deeper forms of sedation should be administered by an anesthesiologist in a setting where the patient can be continuously monitored and emergency equipment is available.
How does sedation differ from general anesthesia?
The main difference between sedation and general anesthesia is the level of consciousness: under conscious sedation the patient breathes on their own and can respond to stimuli, whereas under general anesthesia consciousness is completely switched off and the patient does not respond to any stimulus.
Under general anesthesia the patient's breathing is often supported by equipment, and the procedure is usually performed in an operating room. Preparation and recovery take longer. Under sedation, breathing is usually maintained by the patients themselves, recovery is faster and the patient can often go home the same day with a companion.
General anesthesia may be preferred for very extensive surgical procedures, young children who cannot cooperate or some individuals with special needs. Which method is more suitable is decided jointly by the dentist and the anesthesiologist, taking into account the patient's needs and health status.
Who is sedation suitable for?
Sedation can be used for patients who are expected to have difficulty getting through dental treatment comfortably and who are found suitable in the health assessment. The main situations are:
- Patients with marked fear or anxiety about the dentist
- People with a strong gag reflex when something is placed in the mouth
- Patients undergoing long or extensive surgical procedures such as wisdom tooth extraction or multiple implants
- Patients who find it hard to keep their mouth open for a long time
- Some children and individuals with special needs who cannot cooperate with treatment
- Patients who experience excessive tension during the procedure despite local anesthesia
In some cases sedation may not be suitable or may require additional precautions. These include advanced respiratory and heart disease, sleep apnea, allergy to the medications to be used, pregnancy and certain neurological conditions. That is why a detailed health assessment is carried out before sedation.
What should you pay attention to before sedation?
For sedation to go safely and smoothly, the instructions given before the procedure must be followed fully. In general, the following points are important:
- Share your health information in full: Tell your dentist about your chronic illnesses, all medications and herbal products you use, your allergies and any previous experiences with anesthesia.
- Follow the fasting period: Do not eat or drink for the period specified by the anesthesiologist. The fasting rule is important to reduce the risk of stomach contents entering the airway during the procedure.
- Do not stop your medications without consulting your doctor: Ask your doctor whether you should take your regular medications on the day of the procedure.
- Come with a companion: An adult needs to be available to take you home after the procedure and stay with you for a while.
- Wear comfortable clothes: Choose clothes with sleeves that can be easily rolled up. Avoid nail polish and heavy makeup; they can affect the oxygen measurement taken from the fingertip.
- Plan for afterwards: For the rest of the day of the procedure, do not drive, operate machinery or make important decisions.
If you have symptoms of illness, especially fever, cough or nasal congestion, let your dentist know before the procedure; in these cases the appointment may need to be postponed.
Safety and side effects of sedation
Sedation is considered a safe method when patients are selected appropriately, an experienced team is present and the necessary monitoring conditions are in place. Throughout the procedure, the patient's oxygen level, pulse and blood pressure are continuously monitored. Equipment and medications for intervening when necessary are kept ready.
Common and usually temporary effects that may occur after sedation include:
- Drowsiness and fatigue
- Dizziness or slight loss of balance
- Nausea
- Headache
- Not remembering the procedure
- Slight bruising at the injection site
These effects usually subside within a few hours. Although rare, more serious situations such as slowed breathing or an allergic reaction can occur; continuous monitoring and an experienced team allow a rapid response to such situations. If you notice an unexpected symptom after the procedure, contact your dentist. You can find answers to other questions about dental treatment on our frequently asked questions page.
If you have been avoiding dental treatment
If you have been putting off dental treatment for a long time because of anxiety, talking openly about it with your dentist is often the first and most important step; for many patients, even step-by-step explanations and short appointments make a significant difference. At our polyclinic in Park Oran Ofis in Oran, Çankaya, your anxiety and treatment needs are assessed together, and after the examination we explain whether sedation is suitable for you and how it could be planned.
Frequently asked questions
Will I sleep under sedation?
Under conscious sedation the patient usually experiences deep relaxation and drowsiness, but is not completely unconscious and can respond when spoken to. Many patients do not remember most of the procedure afterwards. Under general anesthesia, by contrast, consciousness is completely switched off.
When can I drive after sedation?
The medications used for sedation can affect attention and reflexes for a while. For this reason it is recommended not to drive for the rest of the day of the procedure. You need to go home with a companion after the procedure.
Can children be sedated?
For some children who cannot cooperate with treatment, sedation or general anesthesia options may be considered after a health assessment. The decision is made according to the child's age, health status and the scope of the treatment. It must always be carried out by a specialist team with appropriate equipment.
Will I feel pain during sedation?
Sedation reduces anxiety and helps the patient relax; pain control is provided by local anesthesia given together with sedation. Using the two together increases comfort during treatment. The patient's condition is monitored continuously throughout the procedure.
