How Your Child’s Nutrition Affects Their Oral Health

by Dr. Steve Whittemore, D.D.S. | Published August 15, 2022

Encouraging good oral health practices in your children begins with good oral hygiene practices—brushing at least twice a day and daily flossing. But what you allow your children to eat also plays an important role in good oral health. By selecting foods that provide the proper nutrients you can help strengthen your children’s teeth with every bite.

Selecting the Right Foods

Teeth need a variety of minerals and vitamins to help sustain oral health. While you can supplement these requirements by taking daily vitamins, it is important to eat foods that are rich in these vitamins and minerals. See the table provided below for a list of the important nutrients, how they support your child’s health, and which foods provide a rich source for each nutrient.

Vitamin B3 (niacin)B3 deficiency can lead to bad breath and canker soresChicken and fish
Vitamin B2 (riboflavin) and B12B12 and/or B2 deficiency can lead to canker soresB2: pasta, bagels, spinach, and almonds

Snacks Between Meals

It’s best to avoid snacks between meals if at all possible. Your mouth produces less saliva during snack times which allows more food and bacteria to stay lodged in your mouth. This, in turn, can lead to tooth decay and other oral hygiene problems.

If snacking between meals cannot be avoided, it is best to choose snacks which promote oral health over options which are more likely to cause cavities. Good snack options include: raw vegetables, nuts and seeds, cheese, yogurt, milk, meat, and eggs. You should avoid food made from fermentable carbohydrates such as bananas, potatoes, rice, corn and wheat flour.

Sugar-free chewing gum can be a great alternative to a snack because it promotes the production of saliva which works to flush your mouth of plaque and bacteria. 


When it comes to beverages, water is the clear winner! Water is pH neutral and does an excellent job at washing food, bacteria, and plaque out of your mouth. Additionally, proper hydration is essential for the production of saliva.

Other tooth-friendly beverages include milk and green tea. Milk contains Vitamin D and Calcium which are both essential for healthy teeth. Green tea contains polyphenols, which reduce bacteria, and fluoride which strengthens teeth. Cranberry juice, if not sweetened with sugar, can also be a healthy choice. Cranberries are rich in anthocyanins which act to prevent the growth of bacteria.

You should avoid drinking fruit juices, carbonated soft drinks, and sports or energy drinks. These beverages are highly acidic, which erodes your teeth’s enamel,  and often contain high levels of sugar, which promotes plaque and bacteria growth.
