When can i use waterpik after lanap?

Waterpick -LANAP use: The purpose of lanap is to heal the periodontal pockets. Disruption of the clot formed by the laser is detrimental to long term healing. Therefore, the best you can do is let the area heal without disturbing it for the first few weeks. I don't suggest that therapy until the gingival fibers are matured and well-established.

4 weeks: You need to give about 4 weeks for the gums to attach to the teeth.
