This invention relates to a toothbrush that utilizes a replaceable brush head having rubber gum guard on its top surface and a triangular shaped rubber pad on its bottom surface. The rubber gum guard is shorter than the height of the bristles and is positioned on the peripheral edge of a brush head for functioning as a sensor for providing feedback to prevent brushing at excessive pressures and improper angles as well as for massaging the gumlines without the risk of gum damages. The triangular shaped rubber pad is for conforming to and massaging gumlines at the back of teeth. The replaceable brush head having the rubber gum guard and massaging pad features is economically used in conjunction with a permanent handle that dispenses dentifrice material to the top of bristles. The handle has a resilient contractible connector for secure mounting of the replaceable brush head.

A method of endovenous laser treatment in disclosed.
