Dental anxiety is both very real and very common fear. Sometimes this fear can keep patients out of the dental chair for long periods of time, even years, leaving them with poor oral health. Dr. Guerra is sympathetic to patients with dental anxiety and wants to help. One method he uses is nitrous oxide sedation. Nitrous oxide is a sedative gas, proven to be helpful in relieving any stress you feel during dental procedures. Once your dental work is completed, oxygen is administered to clear your head. The effects of nitrous oxide generally wear off quickly, and you will be functioning normally. Most patients are able to drive home or return to work. Properly administered nitrous oxide sedation is safe and effective.
