Tom's Antiplaque plus Whitening Gel Toothpaste helps control plaque buildup and whiten teeth, every time you brush, without artificial ingredients or harsh abrasives that can damage enamel. Plaque is a sticky deposit that accumulates on teeth, and is the first stage of cavity development, tartar formation, and tooth staining. Tom's of Maine Antiplaque plus Whitening Gel Toothpaste cleans teeth and helps prevent plaque, when used as a part of a complete oral hygiene program. We've added silica to improve cleaning and remove stains that form on our teeth over time, making your teeth whiter. Fluoride - free formula. Some people do not want fluoride in their toothpaste. We produce fluoride - free toothpaste because we respect our customers' diverse needs and interests.
