Nitrous oxide, more commonly referred to as “laughing gas” is an excellent sedation method to help fearful and anxious patients relax during dental treatment. We offer this option for a nominal fee. It is colorless and odorless. Nitrous oxide's usefulness also stems from how quickly it works and that its effects are reversible. Within seconds of removing the nitrous oxide, the gas is released from your system allowing you to be able to return to work or drive right after your appointment.
