About Replace the Brush

These guides are for adults who want to brush a little more effectively and are tired of vague advice about toothbrushes. They are written to be read quickly, often on a phone, and to give one clear answer at a time.

The site covers a single everyday question, how often to replace a toothbrush, from the three-month guideline to bristle wear, illness, electric heads and storage. It sticks to conventional, widely shared advice and does not promise results from any product.

The aim is to help readers make sense of everyday oral health topics. It is an independent guide, not a clinic, and it is no substitute for a conversation with your own dentist or dental team.

What you will find here

Replace the Brush publishes 5 guides about how often to replace a toothbrush, among them The Three-Month Rule, Signs of Frayed Bristles, Replacing a Brush After Illness.
