How safe is nitrous oxide? Very safe.
Nitrous oxide/oxygen is perhaps the safest sedative in dentistry. It is non-addictive. It is mild, easily taken, and quickly eliminated from the body. Your child remains fully conscious and keeps all natural reflexes when breathing nitrous oxide/oxygen. If nitrous oxide/oxygen will be used at a visit, we ask that you give your child little or no food before the visit. Nausea or vomiting may occur when a child has a full stomach.
