When's It DueHow often
How often should you replace electric toothbrush heads?
Every 3 months
Oral-B, Sonicare and similar heads follow the same three-month rule as a manual brush. The handle lasts years; the head is the bit that wears out.

Why replace it
The bristle field packs down with daily use. A fresh head restores the clean you paid for when you bought the handle.
