Deep fissures can develop in teeth. If bacteria continue to make their way under the gums, they expand. Toothbrushes don’t have the capacity to clean these cracks because they’re so tiny. As the hole grows deeper in time, and become harder to clean. If left untreated long enough, cavities can form. One way to stop cavities from forming is to seal up the fissure. This is the place where dental sealants are used. The fissure can be lined and sealed so bacteria can’t get down there. i9qqphd5e2.
