How To Change An Electric Toothbrush Head

Turn off the handle, follow the manufacturer’s removal direction, clean the shaft and attach the correct head.

What matters for this question

Switch the handle off and follow its manual: some heads pull straight off, while others use a different release motion. Never force an unfamiliar connector.
Rinse and dry the shaft, then seat the correct new head as instructed. A small designed gap can be normal on certain products.

How to apply it

Use the manual’s movement, not a guessed twist. After removal, look for a broken plastic sleeve or buildup on the shaft; both can make a correct new head seem incompatible. A new head should seat as the maker describes without extra force or improvised tools.
