The Laser Irradiatro is the world’s first laser toothbrush that uses low level laser therapy to treat dentin hypersensitivity (sensitive teeth). The purpose of Dental. M® is to treat hypersensitivity by reducing the enlarged diameter of the affected dentine tubules. How long does it take for the treatment? Each treatment takes five minutes while brushing your teeth.

• Component: laser toothbrush, 2 replacement brush heads, 1 x 1.5V AA battery, case, manual.
• What is Dental. M®?  Dental. 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.
• What causes 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.
• How does Dental. M® cure the 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.
• For the best results, it is recommended to use Dental. M® on problem area two to three times per day over a period of four to six weeks.
