Dr. M® is the world’s first laser toothbrush that uses low level laser therapy to treat dentin hypersensitivity (sensitive teeth). Dr. M® is more than just a pain reliever, it cures sensitive teeth. It is clinically proven by leading hospitals and universities. It’s a medical device.

• Sensitivity: As we age several things happen to our teeth. First, a lot of people grind their teeth so they are losing enamel on teeth. However, the biggest one is the recession of gums it can happen from brushing too hard. Do not forget always to use soft toothbrush. It can be as bad as not being able to eat ice cream, not being able to drink cold beverages or even hot water and not even going to get teeth clean because you are so sensitive when you do that.
• The way Dr. M® cures hypersensitivity: Dentin hypersensitivity in most cases is related to exposure of root surface by recession of gums. A tooth with dentin hypersensitivity has dentinal tubules twice the size of a normal tooth’s dentinal tubules.
• The purpose of Dr. M® is to treat hypersensitivity by reducing the enlarged diameter of the affected dentinal tubules.
• The time of each treatment: each treatment takes five minutes while brushing your teeth.
• For the best results, it is recommended to use Dr. M® on problem area two to three times per day over a period of four to six weeks.
