0 a dentist who specializes in the treatment of the gums (= the pink flesh in the mouth in which the teeth are fixed) and other tissues around the teeth
The station's interior, occupied by an auto parts store for years, is being renovated and is partially occupied by a periodontist's office.
When he discussed the scene with a periodontist, the periodontist told him that it would be more painful if the torturer drilled into a healthy tooth.
In other cases of endodontic treatment failure, a referral to a periodontist or an oral and maxillofacial surgeon for replacement of the tooth with a dental implant may be indicated.
