What matters for this question
- The ADA’s general advice favors soft bristles because they reduce the risk of gum abrasion. A manufacturer may use medium-soft as a separate product description.
- Do not infer that a medium or firm option cleans better for a particular person. Confirm the package wording and technique advice for your situation.
