- Increase your calcium intake by consuming dairy products such as milk, cheese, and yogurt.
- Drink unsweetened beverages like water, unsweetened tea, or fruit smoothies, rather than sugary drinks, which can harm your teeth.
4. Try kaolin clay for whitening your teeth
Applying kaolin clay to your teeth and brushing gently can help whiten them. Just ensure you don’t scrub too hard, and rinse thoroughly with water afterward.
5. Include vitamins and supplements in your diet

In addition to cutting out sweets, incorporating certain vitamins and supplements can support healthy saliva production, which helps fight plaque.
- Whole grains provide iron and vitamin B, and they also contain magnesium, which helps your body absorb calcium for stronger teeth.
- Eating more seafood, such as salmon or tuna, can provide vitamin D, which is essential for strong teeth.
6. Choose low-abrasive toothpaste

Toothpaste needs to be abrasive enough to clean effectively, but too much abrasion can damage enamel. You can test your toothpaste’s abrasiveness by applying a bit on foil, rinsing it with water, and checking for any scratches. More scratches indicate a higher abrasiveness.
7. Chewing sugar-free gum is beneficial for your teeth
It may sound surprising, but chewing sugar-free gum can help prevent cavities. It stimulates saliva production, which helps wash away food particles, neutralize acids, and strengthen enamel.
8. Hold your toothbrush with three fingers
Holding your toothbrush like a pen gives you better control over the pressure you apply. Gripping it too tightly can cause you to over-brush, which can damage your gums and enamel. It’s not the pressure that cleans your teeth, but the bristles working to remove plaque and bacteria effectively.
