Look at the bristles
Include a quick visual check in your routine. Bristles that are visibly worn, spread, or damaged are a reason to consult the head’s replacement guidance.
A calendar reminder can help you keep track of the manufacturer’s suggested replacement interval.
The American Dental Association's general toothbrush guidance suggests replacement about every three to four months, with earlier replacement when bristles become worn or spread. For a powered-brush head, also follow the replacement instructions for your exact model.
When should you replace a manual toothbrush?
With a manual toothbrush, replace the whole brush rather than a removable head. The ADA recommends replacement about every three to four months, or sooner when bristles look matted or frayed.
Use a reminder to check the bristles, rather than waiting for the next calendar date when they are already worn. Cleaning and careful storage remain useful between replacements.
Check the fit before buying
The product name, compatible handle models, and head type should all match your needs. Do not rely only on a similar-looking connector or a photograph.

Choose for everyday comfort
Compare the head descriptions and bristle options available for your handle. If you have a particular concern about sensitivity or dental work, ask your dental professional for guidance.
Careful technique still matters whichever compatible head you choose.
Care for the head between uses
Clean the head according to the instructions and store it so it can dry appropriately. Keep individual brush heads separate and replace a damaged head rather than trying to repair it.
