Sleep dentistry, also known as sedation dentistry, uses medication to help patients relax during dental procedures. While the name implies that patients will be asleep, they are usually awake, except for those under general anaesthesia. Conscious sedation is a method of relieving dental anxiety through the use of sedative drugs. Midazolam, a derivative of the class of drugs called benzodiazepines, is commonly used in dental sedation. Other commonly used drugs include ketamine, propofol, dexmedetomidine, fentanyl, verced, precedex, and triazolam.

Midazolam: a benzodiazepine that induces amnesia
Sleep dentistry, also known as sedation dentistry, uses medication to help patients relax during dental procedures. Conscious sedation is a method of relieving dental anxiety through the use of sedative drugs. While the patient remains awake, they are less aware of the procedure and may not remember what happened afterward.
Midazolam, also known as Verced, is a benzodiazepine commonly used in dental sedation. It is generally considered very safe, inducing only a mild form of sedation. Midazolam is unique in its ability to produce retrograde amnesia, ensuring patients are unlikely to remember the procedure. This makes it ideal for sleep dentistry. The amnesia-inducing effects of midazolam are complemented by its hypnotic qualities, which further aid in the sedation process.
Midazolam is administered orally and takes effect within two to three minutes. The sedation typically lasts between 60 and 120 minutes. It is important to note that midazolam has a higher impact on the respiratory tract than the circulatory system. As a precaution, patients with respiratory infections on the day of the procedure should reschedule.
Midazolam is particularly useful in sleep dentistry due to its ability to induce amnesia and its minimal effect on the functioning of the heart and lungs. This drug helps patients feel more comfortable and relaxed during dental visits, making it a valuable tool for dentists to ensure patient well-being and cooperation.

Propofol: fast-acting, may be continuously administered
Sleep dentistry, or sedation dentistry, is a method of relieving dental anxiety through the use of sedative drugs. Patients are usually awake during the procedure, except for those under general anaesthesia. Sedative drugs can be administered orally or intravenously (IV).
Propofol is a fast-acting sedative drug used in sleep dentistry. It is administered via injection into a vein. The effects of propofol can be felt in as little as 90 to 100 seconds. As the body clears the medication quickly, it may be continuously administered throughout the procedure. Propofol can be given to both adults and children, but patients should be carefully monitored as a drop in blood pressure is a known side effect. The Food and Drug Administration (FDA) states that propofol should not be given to patients with known allergies to the drug or its components, such as egg or soybean products.
Oral sedatives are also commonly used in sleep dentistry. Triazolam is a popular choice for oral sedation as it provides good mild to moderate sedation lasting 1-2.5 hours. Valium, diazepam, and Xanax are typically used for lighter oral sedation and usually do not require patient monitoring. Midazolam is another commonly used oral sedative, inducing only a mild form of sedation. It is generally considered safe and can be used for both adult and paediatric patients, although those with respiratory infections should not take it due to its impact on the respiratory tract.
IV sedation is often used for longer procedures, high anxiety, difficulty getting numb, or severe gag reflexes. Drugs used for IV sedation include fentanyl, verced (midazolam), and precedex.

Ketamine: suitable for short procedures, often used with other drugs
Sleep dentistry, or sedation dentistry, is used to help patients relax during dental procedures. Conscious sedation is a method of relieving dental anxiety through the use of sedative drugs. The patient is awake but less aware of the procedure and may not remember what happened afterward. Ketamine is a drug that can be used for conscious sedation and is suitable for short procedures. It is a derivative of the psychedelic drug phencyclidine and is usually injected into a vein. The effects of ketamine begin to manifest about a minute after administration and last between five and ten minutes. It is also often used in combination with other drugs.
Ketamine is a fast-acting drug, with effects felt in as little as 90 to 100 seconds. It is cleared quickly by the body, so it may be continuously administered throughout the procedure. The Food and Drug Administration (FDA) considers ketamine safe and effective for patients under 16 years old. However, it is not suitable for patients who are sensitive to the drug or who may experience adverse reactions to elevated blood pressure.
There are a variety of other sedative drugs used in sleep dentistry, including oral and intravenous (IV) medications. Oral sedatives include triazolam, valium, diazepam, and xanax. These drugs can range from mild to moderate sedation, depending on the dose. IV sedatives include midazolam, propofol, and fentanyl. Midazolam is a commonly used drug in sleep dentistry and is generally considered very safe, inducing only a mild form of sedation. Propofol also acts fast and can be continuously administered, but it is not recommended due to the risk of overdose. Fentanyl provides sedation and a sense of euphoria.
Nitrous oxide, or "laughing gas," is another form of sedation used in dentistry. It is a minimal sedation method where the gas is breathed in through a mask, helping the patient relax. It is safe for children and can be administered by most dentists.

Dexmedetomidine: induces sleep-like state, administered through a vein
Sleep dentistry, or sedation dentistry, uses medication to help patients relax during dental procedures. Conscious sedation is a method of relieving dental anxiety through the use of sedative drugs. The patient is awake but less aware of the procedure and may not remember what happened afterward.
Dexmedetomidine is a potent sedative drug that puts a patient in a sleep-like state. It is administered continuously through a vein throughout the procedure, and the medical professional can still communicate with the patient. Because it can affect a patient's breathing and heart rate, low doses are usually given.
Dexmedetomidine is a type of IV sedation, which is best for longer cases, high anxiety, people who have difficulty getting numb, or individuals with severe gag reflexes. IV sedation allows the dentist to continually adjust the level of sedation.
There are also oral sedatives, which can range from minimal to moderate. For minimal sedation, patients take a pill, usually Halcion, which is a member of the same drug family as Valium. A larger dose may be given to produce moderate sedation.
Nitrous oxide, or "laughing gas," is another form of minimal sedation. It is inhaled through a mask placed over the nose, and the dentist can control the amount of sedation received.

Nitrous oxide: safe for children, administered through a mask
Sleep dentistry, or sedation dentistry, uses medication to help patients relax during dental procedures. Nitrous oxide, commonly known as "laughing gas", is a safe and effective method of sedation for children. It is a mild sedative that does not affect heart rate and has no ill effects on the heart, lungs, liver, kidneys, or brain. Nitrous oxide is typically administered through a small mask placed over the nose, through which the patient inhales the gas mixed with a large quantity of oxygen. The effects of nitrous oxide are gentle and short-lived, wearing off within minutes of the gas being turned off.
Nitrous oxide is a popular choice for sedation in children due to its safety profile and ease of administration. It has been used in dental procedures for over 100 years and is often preferred over heavier anesthetics because the child remains awake and aware during the procedure. The dentist can control the dosage of nitrous oxide, ensuring that the child feels relaxed, happy, and comfortable without experiencing excessive drowsiness. The child can still understand and respond to instructions and move their arms and legs if needed.
The procedure typically involves placing a soft mask over the child's nose, through which they breathe normally. The gas is usually scented with a Chapstick flavour of the child's choice, ranging from ice cream to fruit flavours. The gas is administered a few minutes before the dental procedure begins and is continuously inhaled until the treatment is complete. The dentist monitors the child's vital signs throughout the procedure to ensure their health and safety.
While nitrous oxide is considered very safe, it is important to be aware of potential side effects. Most side effects are uncommon and occur due to inhaling too much gas or fluctuations in dosage. These side effects may include nausea, vomiting, sweating, shivering, fatigue, or dizziness. However, these effects are generally mild and can be quickly alleviated by providing oxygen and turning off the sedative gas. It is important to note that the risk of side effects is lower with nitrous oxide than with other forms of sedation, such as oral conscious sedation, IV sedation, or general anesthesia.
Nitrous oxide is a safe and effective option for children who are anxious or nervous about visiting the dentist. It helps ease their nerves and makes them feel more comfortable during the procedure. It is important for parents to understand the facts about nitrous oxide and discuss any concerns with the dentist before making an informed decision about their child's sedation during dental procedures.
