A man making a surprised face while using a water flosser on his tonsils.

A man is in a kitchen, holding a black water flosser. He demonstrates how to use it, first showing a high-pressure mode, then switching to a gentler mode. He uses the device on his tonsils, making a surprised face. The video cuts to a close-up of a dentist-like figure who explains the different modes of the water flosser.
