Vitamins and Minerals for Healthy Teeth and Gums
Which nutrients matter for teeth and gums, where to get them from food, and when a supplement makes sense.
This article is general information, not dental or medical advice. If you have symptoms, please see a dentist.
Your teeth and gums are living tissue, and they rely on the same nutrients as the rest of your body. Here are the ones that matter most, and how to get them.
| Nutrient | Why it matters | Food sources |
|---|---|---|
| Calcium | Almost all of the body's calcium is stored in bones and teeth. | Milk, yogurt, cheese, fortified plant drinks, canned fish with bones, leafy greens |
| Phosphorus | Works with calcium in bones and teeth. | Dairy, meat, fish, eggs, nuts, whole grains |
| Vitamin D | Helps the body absorb calcium. | Sunlight on skin, oily fish, egg yolks, fortified foods |
| Vitamin C | Needed to make collagen; severe deficiency (scurvy) affects the gums. | Citrus fruit, peppers, strawberries, broccoli, kiwi |
| Vitamin A | Supports cell growth and the immune system. | Liver, dairy, eggs, carrots, sweet potatoes, leafy greens |
| Vitamin K | Involved in blood clotting and bone metabolism. | Leafy greens (K1); fermented foods and some cheeses (K2) |
| Zinc | Supports immune function and healing. | Meat, shellfish, beans, nuts, seeds |

Do you need a supplement?
Most people who eat a varied diet get enough of these nutrients. A supplement may make sense if your diet is limited, if a blood test shows a deficiency, or if a doctor recommends one.
More is not always better. Vitamin A, vitamin D, calcium and zinc can all cause harm at high intakes, and totals add up across products. Vitamin K can interact with the blood thinner warfarin.
Oral health supplements
Some supplements, such as Dentitox Pro, combine several of these nutrients in one product marketed for teeth and gums. When comparing any product, look for:
- The full Supplement Facts label, with the amount of each ingredient
- Whether the finished product has been tested in published studies
- Independent quality testing, not just seller badges
- A clear refund policy
And remember: no supplement replaces brushing, cleaning between teeth and dental visits.
Frequently asked questions
Can vitamins reverse cavities?
No. Once a cavity has formed it needs treatment from a dentist. Good nutrition and fluoride help protect teeth, but vitamins do not repair cavities.
Which vitamin deficiency causes gum problems?
Severe vitamin C deficiency (scurvy) can cause swollen, bleeding gums. It is rare in people who eat fruit and vegetables.
