The present invention relates to a tooth coating applicator (10), typically inthe form of a strip (11), and a method for applying a dental sealant to asurface of a tooth (T), and specifically to the interproximal surface (S)thereof. The applicator (10) is elongated and is adapted to be typicallyinserted into an interproximal space (I) defined between a pair of adjacentteeth (T, T') and to be gradually slid against a dental surface of one of theteeth. The applicator (10) comprises a series of substrates (12, 14, 16, 18,20, 22, 24, 26, 28, 30, 36, 40, 42) for generally successively removing debrisand deposits from the interproximal dental surface (S), etching (20) thedental surface (S), washing (22) the dental surface (S), drying (24, 26) thedental surface (S), carrying (28) the sealing agent and applying the sealingagent to the dental surface (S), exerting pressure (30) on the dental surface(S) during the hardening of the sealing agent, and polishing (36, 38) thedental surface (S) and its cured sealing agent.
