With sedation, the dentist administers a drug before or during the dental procedure. Only one type — general anesthesia — renders the patient completely unconscious. The other forms will relax you, but won’t knock you out completely.
- Nitrous oxide: A gas that relaxes you during the procedure. It wears off quickly, so your dentist might let you drive yourself home after the appointment.
- Oral sedatives: Oral sedatives, such as diazepam, also help relax patients during dental procedures. You typically take them an hour or so before your appointment. You’re fully awake but less anxious, and you might feel a little sleepy until it wears off.
- Intravenous sedatives: Intravenous, or IV, sedatives can put you in varying stages of consciousness. This is also known as general anesthesia and, as mentioned above, will put you into a deep sleep until it wears off. Other IV drugs, however, can put you into a “twilight sleep.” You’re less aware of your surroundings, you might feel sleepy, and you might not remember much of the procedure once it’s over.
Some patients assume that general anesthesia offers the best solution. However, it also comes with
more potential side effects than the other methods, so you might want to consider a lesser form of sedation dentistry. If your dental care provider mentions sleep dentistry, he or she likely means general anesthesia.
You might prefer dental sedation or sleep dentistry, but talk to your dentist about it first. Mention any allergic reactions you’ve experienced in the past, especially to anesthesia, so your dental professional can make safe, educated recommendations.
Additionally, you can discuss local anesthetics. These drugs numb your mouth during a dental procedure so you don’t experience pain. Dentists usually administer local anesthetics with a short needle in several places along the gum line. If you don’t fear the dentist, local anesthetic might be the only thing you need.
