1 Answer

Nitrous oxide can be used to reduce pain sensitivity and/or anxiety during dental procedures. It is administered through a mask combined with the right amount of oxygen. The sedative effects of nitrous oxide usually become effective in a matter of minutes and last until dental work is finished at which time the patient receives pure oxygen to eliminate the sedative in about five minutes. What can be done for sensitive teeth? Are you experiencing occasional tooth pain while brushing, flossing, or even drinking a beverage that is too hot or cold? Apple Dentistry can analyze and help you find a solution for this annoyance. It may be as simple as changing your toothbrush, toothpaste, or diet. We'll be able to identify other causes, such as compromises in the tooth's protective enamel or root exposures. Special fluoride gels, sealers, fillings, or bonding may be employed to stop sensations from making it to the core or roots of your tooth. more
