Nitrous Oxide (N2O) Sedation Dentistry in Waldorf, MD

Not everyone is a fan of visiting the dentist. In fact, some people are so afraid of stepping into a dental office that they simply avoid doing so for years. However, these individuals need to understand that skipping dental appointments is very detrimental to their teeth, since regular dental cleanings are the key to having healthy, cavity-free teeth. Only a dentist can remove the plaque and bacteria that regular brushing and flossing misses, as well as spot the early signs of dental disease. Luckily, for people who are afraid of the dentist or have a severe gag reflex that keeps them from being able to handle tools in their mouth, our Waldorf dentists offer sedation dentistry options that can help them stay calm during dental work.

There are three kinds of sedation dentistry – IV, oral conscious and Nitrous Oxide (N2O). When patients chooses N2O sedation, the dentist will place a mask over their face and administer a non-allergenic, non-irritating gas that will place them in a state of relaxation that will allow them to feel calm and collected during the procedure. As sedation goes, this is one of the safest options available. The goal of N2O sedation is not to put people to sleep, but to allow them to have a more enjoyable experience at the dentist that will keep them from feeling pain and anxiety. Patients will still be able to respond to any requests the dentist, all while remaining comfortable.

It is extremely easy to administer N2O. A dentist will simply tell patients to breathe normally into a mask, and then within three to five minutes they will be able to feel the N2O take effect. There might be some light-headedness or tingling when the N2O is administered, but other than that there is little discomfort associated with this gas. In fact, many people report experiencing well-being, euphoria and/or floating.

The best part is the all a patient has to do is breathe normally following a procedure for the effect of N2O to wear off. This process just takes three to five minutes before a patient is feeling normal again. It’s important for patients to feel comfortable to visit the dentist every six months. This is why people should look into all of the options our Waldorf dentists can offer that will allow them to have a comfortable experience at the dentist.
