What matters for this question
- Check both bristle wording and head size. A small or rounded head may change access, but the manufacturer’s fit list still controls whether it attaches.
- If gums remain sore or bleed, do not use a product tag as a diagnosis. Ask your dentist about technique and the underlying cause.
