Brush Head Wobbles Or Does Not Fit

Stop forcing the head. Check connector, leftover plastic and toothpaste buildup.

What matters for this question

Compare the exact connector family first. A wrong head can look close but fail to seat, and forcing it can damage the shaft.
If a known-correct replacement fails, inspect for hardened paste or leftover plastic from the old head and follow manufacturer troubleshooting.

How to apply it

A designed small gap can be normal on some Sonicare or Philips One handles, whereas rocking, detachment or the need to force a head is different. Compare the manufacturer’s fitting instructions for your exact model. If a correct replacement still behaves oddly, inspect the shaft rather than trying unrelated heads.
