Lavany Water Flosser, $38 with code ML5S4BNG

It’s not a Waterpik, but this Lavany water flosser has color-coded nozzles for the whole family, a UV light to kill germs, and is just $38 today (with code ML5S4BNG).

Some dentist argue using a water flosser is more effective than traditional flossing. Plus, $38 is way cheaper than paying to fill a cavity.
