Toothbrush App Shows Wrong Device Name? What to Do
Short answer: Open your toothbrush app's device settings and rename the handle, or remove it and pair it again from Bluetooth. For shared brushes, select the correct profile when it reconnects. If the old name stays, forget the device from the phone's Bluetooth list and, if needed, reset the brush before pairing. Your brushing history should then sync under the right name.
Why the wrong name appears
A connected toothbrush has two identities: the Bluetooth name the handle broadcasts and the device name the app saves. The screen usually shows the saved name, not the live broadcast, so that label can stay behind if you pair a different handle to the same phone or if a previous name remains in the app. This is most common when two brushes from the same brand use the same app.
A wrong displayed name is rarely a hardware failure. It is a pairing or profile issue, and it can usually be fixed in the app without replacing the brush. If you are shopping for a new brush and want less of this confusion, start with the app or Bluetooth toothbrushes guide, then compare smart toothbrushes for profile controls.
Rename the brush in the app first
Open the toothbrush app before touching your phone's general Bluetooth settings. Most apps have a device page or a settings menu that lists the connected handle. Look for an edit icon, a pencil icon, or a menu item named rename. The exact wording changes from app to app, but the place to change the displayed name is almost always in the device or accessories section.
Choose a name that tells you which physical brush this is. A person's name works well; so does a location such as upstairs or travel bag. Avoid using the same name for two handles. If you cannot find the setting, review toothbrush app features and the guidance on how to get most from your toothbrush app.
- Open the app and tap the paired toothbrush.
- Look for rename, edit, or device settings.
- Enter a unique, recognizable name.
- Save, then go back to the home screen to confirm.
Remove the old pairing and pair again
If the rename option does not work, the old name may be stored in the phone's Bluetooth list. Forget the toothbrush from the app first, then open the phone's Bluetooth settings and remove the saved toothbrush. Next, put the handle back into pairing mode according to its manual and add it in the app again.
When you pair again, make sure the correct user is active. If you do not, the app may assign the handle to the wrong profile. For step-by-step setup, see connect a Bluetooth toothbrush to the app and for troubleshooting see toothbrush Bluetooth pairing fails.
| Symptom | What to do |
|---|---|
| The app shows an old name after a rename | Forget the device in the phone's Bluetooth list, then pair it again. |
| The app pairs to a different handle in the house | Remove the wrong handle from the app's device list and reselect the correct brush. |
| The old name returns every time | Reset the toothbrush, then add it as a new device. |
Reset the brush when the name is stuck
A factory reset should be your next step if the name will not update after you forget and re-pair. Resetting clears the handle's saved Bluetooth link and returns the device to a new-brush state. Check the manual for the correct button sequence, because it differs by model.
After a reset, pair the toothbrush again before changing the name. If the app offers a firmware update, install it as well. Updates often improve how the handle and phone remember names. Use reset smart toothbrush and update smart toothbrush firmware for more detail.
Check your brushing history after the fix
After the displayed name is correct, open the brushing history and confirm the most recent session appears under the intended profile. A cosmetic name error does not always mean the data is lost. The app may have recorded the session correctly even when the label looked wrong.
If sessions still appear under another profile or at the wrong time, look at the session log before you export anything. Resolving those labels now makes later tracking more reliable. See toothbrush app shows wrong brushing time and export toothbrush brushing data.
Keep the app useful after the name is fixed
Once the name is fixed, the app can support a simple routine. The ADA recommends brushing twice a day for two minutes with a fluoride toothpaste, and the app's timer and progress screen can help you keep that habit. A correctly named device makes the history easier to trust.
The same app is also a convenient place for a brush-head replacement reminder. The ADA advises replacing the toothbrush every three to four months or sooner if the bristles are frayed. If you would rather not pair a brush at all, a timer-only model can still guide the two-minute session. The buying guides show which models include the features you want.

Questions
Why does my toothbrush app show the wrong device name?
It usually means the app saved the old Bluetooth name or paired while another user was active. Rename the handle in the app first; if that does not work, forget the device and pair it again while selecting the correct profile.
Will forgetting the toothbrush delete my brushing history?
Usually not. History is stored in the app or in the user's account, not on the handle. To be safe, review the app's settings and sync or export your data before removing the device.
Can I rename my toothbrush in the app?
Yes. Open the device or settings page, look for rename or edit, enter a unique name, and save. The exact menu wording depends on the app.
What should I do if the old name keeps coming back?
Forget the brush in both the app and the phone's Bluetooth list, reset the handle if needed, then pair it as a new device. Also update the app and toothbrush firmware.
Does a wrong device name affect my brushing data?
It may if the app logs sessions under the wrong profile. Check the history after you rename the brush. If sessions landed in another profile, export or review that data before editing.
Do I need a new toothbrush because of a name problem?
No. A wrong displayed name is a software and pairing issue, not a motor or brush-head problem. Try the app settings and pairing steps before considering a new handle.
