Could a waterpik cause gum recession?

Pressure adjustment: Only if turned up too high. Talk to your dentist or hygienist for appropriate setting.

Waterpik: Waterpiks are used to treat gum infections. When infected, the gum tissue swells. When it's healthy, it shrinks. If the waterpik is used properly ( have your dentist or hygienist demonstrate the proper techniques) it will not cause recession, though the healthy tissue will be lower than before.
