What is Sedation Dentistry?
Sedation dentistry involves receiving dental treatment while sedated, often referred to as "sleep dentistry" because many patients rest during the procedure. It should not be confused with treatments for sleep disorders, which is also sometimes called "sleep dentistry." This technique helps patients feel relaxed and at ease during dental procedures by either inducing sleep or minimizing awareness. Sedation often causes mild amnesia, meaning that even if patients don't fully sleep, they usually don't remember the time spent in the dental chair.
What Are the Different Types of Sedation?
There are various types of sedation used in dentistry, each requiring specific certifications and licenses. Below are the most common types, along with their benefits and drawbacks.
-
Nitrous Oxide: Often called "laughing gas," nitrous oxide is not a true sedative but helps patients relax, making it easier for some to fall asleep. It is classified as an anxiolytic, meaning it reduces anxiety. Many patients feel that their appointment passes more quickly while using nitrous oxide, as it dulls awareness of sights, sounds, and sensations during the procedure. One key advantage is that it is quickly cleared from the body after breathing oxygen for about five minutes, leaving no lingering effects and eliminating the need for a driver.
-
Oral Sedation: Oral sedation involves taking a sedative pill before the appointment, typically inducing deep sleep during the procedure. Even if patients remain somewhat aware, they usually have little to no memory afterward. Oral sedation carries a higher risk of complications compared to nitrous oxide, requiring additional training and certification for the dentist. Due to lingering effects, patients must have a responsible adult accompany them and provide transportation to and from the appointment.
Who Should Consider Sedation Dentistry?
Sedation dentistry is an excellent option for individuals whose fear or anxiety about dental procedures prevent them from getting the care they need. It’s also ideal for patients requiring extensive dental work who prefer to complete it in one longer session. Additionally, those with physical or mental challenges that make it difficult to stay calm in the dental chair may benefit from sedation.
However, not everyone is a suitable candidate for sedation dentistry. Factors such as medical conditions, current medications, and other considerations must be evaluated to ensure sedation is safe and appropriate for each patient.
Precautions Regarding Sedation Dentistry
Since sedation involves prescription medications that affect your body, especially your breathing, it's important to share your complete medical history with your dentist. Some medications may interact with the sedative, or you might have a lung condition that could impact the effectiveness of nitrous oxide. If you have developed a tolerance to opioid narcotics or medications like Valium, sedation may have a different effect on you.
To ensure your safety and comfort, it’s essential to disclose all medical conditions and any prescription, over-the-counter, or recreational substances you use.
