If you have dental braces, you may find that they rub against the insides of your cheeks or lips. Sore spots on the inside of your mouth may develop because of this, especially in the first days or weeks of wearing dental braces. The best way to avoid these sore spots is by simply applying a little dental wax on your braces. The wax helps make a barrier between your braces and your lips, cheeks, tongue, and gums. The wax is very easy to apply! For use on dental braces. Promo: Buy 5packs for SGD 8.00 only!!!
