The brush heads also have specialized tips that actually fade with use. This feature allows you to know when to replace the heads because one look and you’ll see how far into their life you’ve gone and how much time you have left with them. This is managed with the special indicator bristles that can be found at the very tip of these brushes. These brush heads work well with dental work. They are designed to clean around implants, bridges, and crowns so even if you have had dental work done, you can expect a thorough brushing experience from them. These brush heads have been proven to be 25% more effective at cleaning plaque than normal toothbrushes. They are also manufactured in such a way that they are able to reach those tiny, hard to reach places that are normally not accessible with a normal brush. That makes them superior at cleaning between gaps and small areas giving you a more potent brushing experience.
