Refresh your electric toothbrush by swapping in a replacement toothbrush head by PURSONIC.

 These toothbrush heads are compatible with Sonicare and Philips electric toothbrushes. 

Each toothbrush head has a different colored base so that you can tell them apart. 

The soft bristles are a light green. 

A row of blue bristles will fade as time passes, reminding you to change your toothbrush head.
