Most of us know the basics: brush and floss daily to keep tooth decay away. But cavities are still one of the most common dental problems worldwide. Luckily, there are some simple habits you can adopt to keep your teeth strong and healthy. Here are 8 practical tips you can start using right now:

---

1. Rethink your diet

What you eat plays a big role in oral health. A study in The British Medical Journal showed that changing your diet can help prevent or even reverse early tooth decay.

• Load up on calcium: dairy products like milk, cheese, and yogurt strengthen bones and teeth.

• Choose unsweetened drinks: swap soda and juice for water, smoothies, or unsweetened tea. Water also boosts saliva flow and keeps your mouth hydrated.

2. Chew sugar-free gum

Chewing gum without sugar stimulates saliva production, which naturally rinses away food particles, neutralizes acids, and strengthens enamel. It also adds calcium and phosphate to your teeth. For people with dry mouth due to medication, sugar-free gum is especially beneficial.

3. Keep your toothbrush fresh

Your toothbrush is your number one tool against cavities — but only if it’s clean and in good shape.

• Pick a small or medium brush to reach every corner of your mouth.

• Skip toothbrush covers, which can trap bacteria. Instead, rinse and air dry your brush.

• Replace your toothbrush regularly since worn bristles clean poorly.

4. Stick to a solid dental care routine

Many people skip flossing or mouthwash, but they’re essential for complete oral care.

• Brush twice a day for two minutes.

• Floss to remove hidden food particles and bacteria under your gums.

• Rinse with mouthwash to kill extra bacteria and keep freshness longer.

5. Visit your dentist regularly

Even the best brushing can’t reach every spot. Professional cleanings remove plaque and tartar, especially around the gum line. Aim for at least one visit a year — your teeth will feel smoother and healthier afterward. If needed, your dentist may use X-rays to detect deeper issues.

6. Add vitamins and minerals

Nutrition supports oral health too.

• Whole grains provide vitamin B, iron, and magnesium — all important for strong teeth.

• Seafood such as salmon, tuna, and mackerel is rich in vitamin D, which helps your body absorb calcium.

• Minimize sugary, sticky foods like candy or jelly, and brush soon after eating sweets.

7. Try coconut oil pulling

Swishing a spoonful of coconut oil for 15–20 minutes draws out bacteria and freshens your mouth. While it won’t reverse cavities, it’s an excellent way to reduce harmful bacteria when combined with brushing and flossing.

8. Make your own natural toothpaste

If you prefer DIY solutions, try mixing these ingredients into a simple remineralizing paste:

• 2 tbsp calcium powder

• ½ cup baking soda

• ½ cup coconut oil

• 1 tbsp salt

• 1 tbsp peppermint extract

• ½ tsp liquid stevia

Blend until smooth and use in place of store-bought toothpaste. It’s natural, antibacterial, and helps restore minerals to your teeth.
