Those with mild dentophobia will find nitrous oxide a beneficial supplement to their routine dental appointments. Whether you need to complete a routine exam and cleaning, restorative treatment, or cosmetic enhancement, nitrous oxide keeps you calm and relaxed during your visit. To receive the sedative, we ask you to wear a non-invasive nasal mask and gently breath normally. As you inhale the sedative, you’ll feel a warm sensation throughout your body. Once the mask comes off, you should be able to resume your regular activities.
