Dr. Raghavendra S Medikeri · 16 February 2026 · 2 min read
What Are Tooth Cavities?
Tooth cavities, also known as dental caries, develop when bacteria in the mouth produce acids that damage tooth enamel. Left untreated, they can cause pain, sensitivity, infection, and eventual tooth loss.
Daily Oral Hygiene Tips to Prevent Cavities
- Brush for 2 minutes, twice daily, with fluoride toothpaste and a soft-bristled brush
- Replace your toothbrush every 3–4 months
- Floss gently once a day to remove plaque between teeth
- Use a fluoride mouthwash to strengthen enamel and reduce cavity-causing bacteria
Diet Tips to Prevent Tooth Decay
- Limit sugary and acidic foods and drinks, and avoid frequent snacking
- Choose water or milk over soft drinks
- Eat a balanced diet including dairy, leafy greens, nuts, seeds, and fish
- Drink plenty of water to wash away food particles and support saliva production
The Importance of Regular Check-Ups
Visit your dentist every six months. Professional cleaning removes plaque and tartar that brushing alone can't, and early detection prevents small issues from becoming serious ones — ask about fluoride treatments and dental sealants for extra protection.
The 2-2-2 Rule for Healthy Teeth

Prevention Is Better Than Cure
Preventing cavities isn't just about avoiding pain or dental bills — it's about maintaining your overall health and confidence. Consistent oral hygiene, a healthy diet, and regular dental visits go a long way toward strong, cavity-free teeth.
