We often make use of nitrous gas, or laughing gas, because it is a safe and effective way to help alleviate some of a child’s dental anxiety. The child has the gas placed on his or her nose using a special nose piece. The nitrous gas itself decreases their gag reflex, keeping the child from wanting to throw up during treatment, and enhances the numb feeling they have, so the child feels more comfortable. After a treatment, it may look like nitrous oxide is still being administered to your child, but the gas switches to oxygen, reversing the effects of the nitrous gas. Nitrous gas is completely adjustable, so that the right dose is given for every child. These features make it an ideal sedative for any patient, especially anxious children.
