This is a moderate level of sedation delivered straight into the bloodstream through an IV line, so it kicks in fast. A lot of patients who’ve had it describe the experience as almost like napping through the whole appointment — they’re aware enough to respond if needed, but the procedure itself barely registers. It’s typically reserved for shorter treatments. One thing to plan for: the grogginess doesn’t always wear off right away once the sedative is stopped, so you’ll want someone else behind the wheel for the ride home.
Nitrous oxide, or “laughing gas,” is used as a mild sedative. It is delivered through a nose hood and is administered throughout the entire procedure. Nitrous oxide can cause an overall sense of happiness and relaxation. Patients often say they feel more relaxed, even a little lighthearted, and pain becomes much easier to tolerate. Nitrous oxide is a very safe gas with very few side effects and has been used for decades in dental offices as a go-to option.
Oral conscious sedation is a great option for those who don’t like getting needles. You will take the medication orally, rather than with an injection. You will not be asleep, but you will be much less sensitive after the experience, and many patients have no recollection of the noises, smells or pain that typically make a visit to the dentist an unpleasant experience. If the procedure takes a long time, an extra dose may be administered during the procedure to maintain your comfort.
This is the deepest level of sedation available, combining IV medications with inhaled gases to put you fully under. It’s typically used for more complex or lengthy procedures where being completely unconscious is the safest, most practical option.
