This is a safe option for your child and very effective in many cases during dental procedures. We put a comfortable mask that fits over your child’s nose so they can smell a sweet-smelling gas, getting the child more relaxed and awake at the same time. The effects of the gas wear off after a few breaths of regular air, so your child can continue with their regular activities of the day. The American Academy of Pediatric Dentistry (AAPD) recognizes nitrous oxide/oxygen inhalation as a safe and effective technique to reduce anxiety, produce analgesia, and enhance effective communication between the patient and the pediatric dentist.
