How to Use the Tooth Decay Risk Checker
Tooth decay happens when bacteria in your mouth break down sugars into acid that slowly dissolves tooth enamel, and diet and oral care habits play a major role in that risk. This checker covers 6 factors — sugar intake frequency, brushing frequency, fluoride use, flossing, dry mouth, and recent cavity history — and calculates a risk score from 0 to 12 along with a risk level.
Frequent sugary food or drinks keep your mouth in an acidic state longer, raising decay risk, while brushing too little or skipping fluoride toothpaste weakens enamel's natural defenses. A dry mouth reduces saliva's ability to rinse away bacteria and acid, raising risk further, and a recent history of multiple cavities may suggest your current routine still needs improvement.
This result is a reference self-check only and does not replace medical diagnosis — an actual cavity diagnosis requires a visual exam and X-rays at a dental office. If your risk is high, start by reviewing your diet and brushing habits, and keep up with regular dental checkups and cleanings.
Frequently Asked Questions
Yes, fluoride strengthens tooth enamel, reducing acid erosion and slowing early decay — this effect is well established. Skipping fluoride toothpaste can raise your cavity risk.
If your risk is high, checkups and cleanings every 3-6 months are a good idea. Even with low risk, at least one checkup a year is recommended.
Even sugar-free, highly acidic drinks like soda or fruit juice can erode tooth enamel. Prefer water when possible, and rinse with water rather than brushing right after an acidic drink.
