Apparatus for treating dentin sensitivity includes a source of oxidizing gas, a handpiece for delivering the gas to a tooth with dentin sensitivity, a cup attached to the handpiece for receiving the gas and exposing a selected area of the tooth to the gas and means for eliciting a response from the patient in re of the dentin sensitivity.
