Milk has long been a staple in children’s diets—and there’s good reason to keep it on the menu! Studies show that drinking cow’s milk regularly does not contribute to tooth decay and may actually offer some protection for teeth.

Milk contains calcium and phosphate, which help strengthen and re-mineralize tooth enamel. It also contains a protein called casein that can form a protective layer on the tooth surface, making it more difficult for harmful bacteria to stick to teeth.

The American Academy of Pediatrics (AAP) and the American Academy of Pediatric Dentistry (AAPD) encourage children to drink pasteurized, unsweetened milk and water daily as part of a healthy diet and good dental routine.

What About Milk Alternatives?

Today, there are many milk alternatives to choose from, including oat, almond, and soy milk. These options can also be part of a healthy diet, but their effects on teeth can vary depending on the ingredients and how they are processed.

Some research suggests that soy milk may help protect enamel by reducing the buildup of biofilm, while oat milk may help reduce certain bacterial counts. However, more research is needed to fully understand the dental benefits of different plant-based milks.

If your child enjoys a plant-based milk, choose one that is unsweetened and as natural as possible. Some milk alternatives contain added sugars, which can increase the risk of cavities and offset any potential benefits.

The Bottom Line

Whether your family chooses cow’s milk or a plant-based alternative, check the label and look for unsweetened options. And remember, water is always a great choice for keeping little smiles healthy!

A balanced diet, regular brushing with fluoride toothpaste, and routine dental visits all work together to keep those smiles strong and healthy.
