Plaque is a sticky film of bacteria that forms on your teeth. If not removed, it can harden into tartar, which can lead to gum infections and other dental issues. The best way to remove plaque and prevent tartar is to maintain good oral hygiene. Brush your teeth twice a day with fluoride toothpaste, floss daily, and use an antiseptic mouthwash. Electric toothbrushes may be more effective than manual ones. Regular dental check-ups and cleanings are essential, as only a dental professional can remove tartar once it has formed. Avoid sugary and starchy foods, and don't smoke, as these can contribute to plaque and tartar buildup.
