Brief Summary

The aim is to test the effect of low level laser therapy on the relief of symptoms after wisdom tooth removal.

Detailed Description

Each Patient will get all four wisdom teeth removed, left and right side separately. After the operation, low level laser therapy is applied intra- and extraorally. Two different lasers are used, one for each side. The two lasers look identical. Only one of the lasers has therapeutic light, the other one shows just non-therapeutic red light. The effect of the low level laser is measured by several parameters and they are compared with the other side. These parameters are pain, swelling and mouth opening. The selection of the lasers to the sides is double-blind and randomized.
