A female patient has a single Miller’s Class 2 gingival recession on the maxillary canine. She has a short and sharp pain at the upper jaw with ice-cold food and drinks. There are two options for treatment:
(1) a non-surgical approach using topical desensitizing agents or laser onto the root surface
(2) a surgical approach using root coverage techniques.

Is a surgical approach a better option than a non surgical approach for treating hypersensitivity in Miller’ class 1 and 2 gingival recession?
