Perform the “squeak test.” Ask your child to wet their finger and rub it quickly across their teeth. If a squeaking sound resonates, your child has “squeaky clean” teeth and has carefully brushed their teeth.

Is it good if your teeth squeak?

In this test you take some floss and rub it back and forth on the surface of your teeth. If you have successfully removed all of the plaque from your teeth, you should hear a squeak sound indicating your teeth are healthy and good to go. Note that unwaxed floss works best to get that “squeaky clean” sound.

Why do my teeth sound squeaky?

Bruxism creates a squeaking noise. As with snoring, the person creating the sound isn't aware of it because it only happens when they're sleeping. Ask your bed partner if squeaking or grinding noises ever disturb their sleep.
