20 ml Oral Care Serum

Tooth Armor is a 20 ml toothpaste serum that combines six active ingredients in one formula. It is intended for adults seeking enamel repair, sensitivity relief, whitening and cavity protection during daily brushing.

Fits Standard Bathroom Storage

The tube measures 4.5 in by 4.5 in by 12.0 in and weighs 70 grams, so it fits on most bathroom shelves or in travel bags without special accommodation. It replaces separate whitening, sensitivity and enamel products, freeing up counter space.

For Users Wanting Multi-Benefit Serum

Suits buyers who want a single serum covering enamel support, gum hydration and stain removal. Not for shoppers who need a larger volume than 20 ml or who prefer a traditional paste texture over a serum consistency.
