Toptheway Toothbrush Replacement Heads Compatible with Philips Sonicare ProtectiveClean DiamondClean C2 G2 W 4100 5100 HX9023 Plaque Control, 10 Pack

Cleans plaque better than other brands I've used and much cheaper too! Gentle on my gums

We love these replacement heads for our electric toothbrushes. The color changing bristles help you keep up when it is time to change the head. Good buy!

As you can see by the attached photos, the model has changed. The current style is on the left, with no white bristles. Notably, there is no metal in the bottom ring now, and the bristle style has also changed. I don’t know if the metal missing will affect the sonic resonance properties/cleaning efficiency. I’ve only used the new head once so far, but it seems slightly smaller than the previous model. I do have an aesthetic preference for the previous style.The gap is the same as previous model, and has not interfered with use. It is a snug fit on my (Costco) Sonicare Protective Clean 5100 model.I repurchased these because they are much cheaper than the replacement heads at Costco, and the last batch worked well.

I have to agree with many other reviews these are better than The brand name. I use a Sonicare and these snap right and the bristles are awesome. Each tooth brush is individually wrapped and has a color change when due for a new one just like the over priced brand name brushes. Highly recommend. You can tell the company has good quality control standards and are not out to rob the consumer.

Fits well on the machine. Works fine
