6. Green Tea

Green tea contains catechins—antioxidants that reduce inflammation and inhibit bacterial growth. It’s a natural cavity-fighter that also supports healthy gums.
How to Add It: Drink 1–2 cups of unsweetened green tea daily. Avoid adding sugar to retain its protective benefits.
5. Fatty Fish (Salmon, Sardines, Mackerel)
Fatty fish are rich in vitamin D, which helps your body absorb calcium. They also contain omega-3 fatty acids, which reduce inflammation and support gum health.
How to Add It: Bake or grill salmon weekly. Try canned sardines on whole-grain toast for a quick, nutrient-dense lunch.
4. Nuts and Seeds (Almonds, Sesame, Pumpkin Seeds)

Packed with calcium, protein, and phosphorus, nuts help fortify tooth enamel and reduce acid wear.
How to Add It: Enjoy a handful of almonds or sunflower seeds as a snack. Sprinkle sesame seeds over stir-fries or roasted veggies.
3. Crunchy Fruits and Vegetables (Carrots, Apples, Celery)
Crunchy produce acts as natural toothbrushes—scrubbing away plaque and food particles. They’re also high in water and fiber, which stimulate saliva production.
How to Add It: Snack on raw apple slices or carrot sticks between meals. Add celery to salads or dips.
2. Leafy Green Vegetables (Spinach, Kale, Swiss Chard)

Leafy greens are loaded with calcium, folic acid, and magnesium. These nutrients support enamel regeneration and healthy gum tissue.
How to Add It: Blend into smoothies, toss into salads, or steam with olive oil and garlic for a mineral-rich side dish.
1. Dairy Products (Milk, Cheese, Yogurt)
Dairy is a powerhouse of calcium and phosphorus—two minerals that are essential for strong enamel. Cheese also helps neutralize mouth acid and promotes saliva production, which protects against tooth decay.
How to Add It: Choose low-sugar Greek yogurt or hard cheeses like cheddar. A glass of milk or a slice of cheese after meals can help remineralizer enamel.
