Tracking one thing
Track When You Last Changed Your Toothbrush
A toothbrush replacement tracker answers one easy-to-forget question: when did I last change it? The American Dental Association says toothbrushes should be replaced approximately every three to four months, or sooner when bristles become matted or frayed. Wen records what happened. It does not inspect a brush or provide dental advice.
Set up a record your household can recognize
Keep one record per person or brush when the distinction matters. The mark should describe a completed replacement, not promise that a future replacement happened.
- Name the person, bathroom, or brush head clearly.
- Mark the record immediately after replacing the brush or head.
- Keep separate records for household members when replacement dates differ.
- Optionally use a reminder as a prompt to inspect or replace, separate from the factual history.
Why the date is easy to lose
A toothbrush changes gradually, and the packaging is usually discarded. Without a receipt, message, or written date, the last replacement can be surprisingly hard to reconstruct. A single timestamp preserves the answer without adding a broader household checklist.
This is especially useful when one person buys replacement heads for several people or manages brushes in more than one bathroom. Each record can stay independent.
What the sourced guidance says
The American Dental Association says toothbrushes should be replaced approximately every three to four months, or more often when the bristles become visibly matted or frayed. It also notes that brush effectiveness decreases as bristles wear.
That guidance explains why people search for the last replacement date. It is not a rule enforced by Wen. Visible wear, product instructions, individual needs, and advice from a dental professional remain outside the app's judgment.

Track the completed change, not an estimate
A useful mark means “this toothbrush was replaced now.” If you are unsure about an older date, start the record with the next confirmed change instead of inventing history.
Optional reminders can prompt a future check, but they remain separate from the factual mark. Skipping or changing a reminder must never rewrite the date on which the brush was actually replaced.
Wen
How Wen helps with toothbrush replacements
Wen keeps a last-tracked time and history for each plainly named toothbrush Sticker. A household member can record a replacement once and let the people who share that Timeline see the same answer.
- Create a Sticker for the specific brush or person.
- Mark it when the toothbrush or brush head is replaced.
- Check Last Tracked instead of guessing from memory.
A replacement record, not dental advice
Wen does not inspect bristles, assess oral health, select a toothbrush, or decide when a particular person should replace one. Use the product instructions and advice from an appropriate dental professional for individual questions.
