How can I prevent tooth decay?
Quick answer
Brush twice daily with fluoride toothpaste, clean between teeth each day, and reduce frequent sugary snacks and drinks. Agree dental check-up intervals with your dentist based on your individual risk.

Why does decay develop?
Mouth bacteria produce acids from sugars and starches. Repeated acid exposure can remove minerals from enamel. Early changes may improve with saliva and fluoride, while an established cavity needs dental assessment and treatment.
A practical routine
- Brush and clean between teeth every day, rather than only when something hurts.
- Reduce repeated sugary drinks and snacks throughout the day.
- Ask about additional fluoride if you have higher decay risk, for example from dry mouth.
Do not wait for pain
Early decay can be symptom-free. Seek assessment for pain, sensitivity or a new change in a tooth. An examination helps distinguish decay from other causes.
