Signs Your Electric Brush Head Needs Replacing

Frayed, matted or bent bristles warrant earlier replacement. Inspect loose plastic too.

What matters for this question

Check for matted, splayed or bent bristles, cracked plastic and a connector that no longer seats securely.
A faded reminder indicator can be another maker-specific cue. A loose head is also a reason to stop and inspect the handle shaft.

How to apply it

Compare the bristles to a new head if possible: splayed tufts, matting and deformation are easier to see side by side. A reminder light is a useful cue when supported, not proof that the physical head is still sound. Damage at the connector deserves inspection too.
