### What is Tooth Plaque? Tooth plaque is a sticky, colorless film of bacteria that forms on your teeth. It can make your teeth feel fuzzy and is most noticeable when you haven't brushed your teeth. ### Why is Plaque Harmful? Plaque buildup can lead to gum disease and gingivitis, which are conditions that cause your gums to become tender, swollen, and sometimes bleed. Over time, severe gum disease can develop, causing the gum tissue to pull away from the teeth and allowing bacteria to destroy the bone supporting your teeth. ### Health Risks Beyond the Mouth Research has shown that bacteria and inflammation in your mouth are linked to other health problems, including heart disease, dementia, and rheumatoid arthritis. Inflammation is a common factor in these conditions, and oral bacteria can enter the bloodstream and affect major organs. ### How Does Plaque Form? Plaque develops when foods containing sugars and starches, like milk, soft drinks, cakes, and candy, are left on the teeth. Bacteria in the mouth thrive on these foods and produce acids that can destroy tooth enamel over time, leading to tooth decay. ### Preventing Plaque Buildup To prevent plaque buildup, brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Pay special attention to the space where your gums and teeth meet. Floss between your teeth at least once a day to remove food particles and bacteria. Avoid sugary and acidic foods, and drink plenty of water to wash away food particles. ### Proper Brushing Technique Hold your toothbrush at a 45-degree angle to your gums and use gentle, circular strokes. Cover all surfaces of your teeth, including the outer, inner, and tops. Don't forget to brush your tongue to remove bacteria and freshen your breath. Spend at least 2 minutes brushing your teeth each time.
