Nitrous Oxide Sedation

Massachusetts rates for HCPCS D9230

Breathing in a mild sedative gas, often called laughing gas, mixed with oxygen through a small mask over the nose during a dental visit. It helps you relax and feel more comfortable during treatment, and its effects wear off quickly once the mask is removed.
