This is why the Collis-Curve Toothbrush works better:

Curved Bristles The Sulcus is the space between the tooth and gum where bacteria breed causing cavities and bad breath. Your dentist uses curved instruments such as a scaler to clean your teeth in the sulcus.

The cleaning action of the Collis-Curve Toothbrush approximates that of 100 scalers working at once to clean your teeth all over, including in the sulcus!

Collis Curve's Unique Design:

The curved design of the bristles allows you to clean all 3 sides of your teeth at the same while eliminating the danger of poking the bristles into your gums. The unique bristle shape and design makes full use of the time the average person spends on their tooth brushing routine and is ideal for everyone.
