How can I prevent tooth decay?
Direct answer
To prevent tooth decay, brush twice daily with fluoride toothpaste, clean between teeth, reduce frequent sugar and acid exposure, drink water, support saliva flow and attend dental check-ups based on your risk. Fluoride helps protect enamel and can support repair in the earliest stage of mineral loss. People with dry mouth, many fillings, braces, high sugar intake or previous cavities may need extra preventive care.
Why prevention is about frequency
Tooth decay is driven by repeated acid attacks when bacteria use sugars and starches from food and drinks. The more often teeth are exposed, the less time saliva has to neutralize acids and repair early mineral loss.
Prevention is therefore not only about avoiding sugar completely. It is about reducing frequency, using fluoride consistently and cleaning plaque from the tooth surfaces where decay starts.
Daily prevention habits
- Brush twice daily with fluoride toothpaste.
- Spit out toothpaste after brushing rather than rinsing heavily.
- Clean between teeth with floss or interdental brushes.
- Limit frequent snacking and sugary drinks.
- Drink water between meals.
- Use extra fluoride if recommended by your dentist.
- Treat dry mouth and medication-related saliva problems.
- Attend check-ups at an interval based on your risk.

|---|---|---|
| Fluoride toothpaste | Strengthens enamel and helps stop early decay progression. | Everyone, especially patients with previous cavities. |
| Interdental cleaning | Removes plaque between teeth where brushing misses. | Patients with tight contacts, bridges, implants or food trapping. |
| Reduced sugar frequency | Fewer acid attacks give saliva more time to recover. | Patients with frequent snacks, soda or sweet drinks. |
| Dry mouth management | Saliva protects and repairs enamel. | Patients taking medications or mouth breathing. |
| Professional prevention | Detects risk early and applies targeted advice or fluoride. | Patients with high decay risk or many restorations. |
What happens at Gloss & Floss Dental Care®?
At Gloss & Floss Dental Care® in Stockholm, we assess decay risk by looking at previous cavities, current plaque, diet habits, saliva, dry mouth, X-rays, restorations and oral hygiene.
Prevention may include fluoride advice, dietary guidance, cleaning instruction, sealants in selected cases, professional hygiene visits and early repair of leaking fillings.
When should you ask for extra prevention?
Ask for extra prevention if you often get cavities, have dry mouth, wear aligners, have many fillings, snack frequently or use medications that reduce saliva.
Practical advice: The best prevention plan is personal. High-risk patients often need more than standard brushing advice.
