- Phosphorus – Works with calcium to rebuild tooth structure. Found in lean proteins (chicken, turkey, fish), eggs, nuts, and seeds.
- Vitamin D – Helps absorb calcium. Sources include fatty fish, eggs, mushrooms, and fortified foods Smile.
- Vitamin C – Supports gum health and collagen formation. Found in citrus fruits, strawberries, broccoli.
- Vitamin A – Maintains soft tissues in the mouth.
- Omega-3 fatty acids – Reduce gum inflammation; found in fatty fish like salmon.
