REQUIRED FOR ANY PERIODONTAL ISSUE
Originally got a brush from my periodontist's office, which received it as a promotional.  It's the tool for the "brush each tooth" approach to dental hygiene.  At each periodontal cleaning I've had since starting to use this brush the hygienist has mentioned continued improvement in my condition.  The tips appear to be identical; the one for "inside" wears significantly quicker than the one for "outside."  Rather than toss both tips together, you can economize by tossing the worn "inside" tip, transferring the "outside" tip to the "inside" hole of the brush, and putting a new tip in the "outside" hole.  It's a useful tool for anyone, a required tool for anyone with existing gingivitis or periodontal disease.
