Groveport Dental Group can provide Nitrous Oxide Sedation at its Columbus, Ohio office. Nitrous Oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe and allows our patient to breathe easily and remain in control of all bodily functions. Nitrous Oxide works rapidly and is controlled easily to provide relaxation, eliminate or reduce gagging and kill pain within 2-3 minutes. There are no side effects and no lingering effects after treatment.
