Replace a toothbrush roughly every three to four months, sooner if the bristles are frayed or matted. Alongside a calendar reminder, check whether your storage arrangement lets the rinsed brush dry.
- Inspect bristles
- Rinse after use
- Air-dry upright
- Record replacement reminder
Check condition and date together
The ADA recommends that interval and earlier replacement for worn bristles. A newer date or higher purchase price does not override visible wear. For an electric brush, check compatible replacement heads and manufacturer care instructions.
| Check | Next action |
|---|---|
| Frayed or matted bristles | Replace sooner |
| New brush started | Record date and reminder |
| Replaceable head | Check compatibility |

Rinse, then let it dry
The ADA advises rinsing after use, storing upright to air-dry and not sharing brushes. Avoid keeping a wet brush in a closed container. A travel cover and a drying place at home need not serve the same purpose.

Change the setup before shopping
If a tight holder keeps your brush wet, first create an upright drying position. Check any sanitizer’s validated conditions separately. A sanitizer purchase is not presented here as a necessary step.
A worked example
Write the start date when you open a new brush and set a reminder a few months ahead. Replace earlier for fraying. After rinsing, check drying space rather than automatically closing a cover.
