What A Toothbrush Head Cannot Clean

A brush head cleans accessible tooth surfaces; it does not replace flossing or professional care.

What matters for this question

Tight spaces between teeth are not effectively reached by ordinary brush bristles. The ADA discusses floss and other interdental cleaners separately.
A replacement head also cannot remove hardened tartar or diagnose pain, bleeding or a failing restoration.

How to apply it

Ordinary bristles clean the surfaces they can touch. They do not reliably clean tight interproximal contacts, remove hardened deposits, or inspect a painful area for disease. A pointed head may improve access to one spot but still does not replace professional assessment.
