Cheese and unsweetened milk can be friends of your teeth, but sweetened milk is another story.
- Cheese and milk provide calcium and phosphorus that support enamel.
- Sweetened milk can still cause cavities.
- Do not let children fall asleep with a milk bottle.
- Choose unsweetened dairy and eat cheese in moderation.
Milk and dairy foods such as cheese and yoghurt are often mentioned when people talk about calcium for teeth. But not every product is the same. This article helps you choose wisely to protect your teeth, and also points out a few everyday habits that can quietly lead to cavities.
Why cheese and milk help teeth
Cheese and milk contain calcium and phosphorus, two minerals that build tooth enamel. Cheese increases the flow of saliva and helps neutralise acid in the mouth after a meal. In addition, the protein in cheese forms a thin protective layer on the tooth surface, which helps limit damage from acid.
Things to watch for
- Sweetened milk, flavoured milk and sweetened yoghurt can still cause cavities.
- Children who drink milk before sleep without brushing are prone to decay.
- Salty or processed cheese contains a lot of salt and should not be eaten in large amounts.
- People who cannot take lactose can choose lactose free milk or plant milk fortified with calcium.
In short, the benefit comes from the calcium and protein, while the harm comes mainly from added sugar and from the timing of when dairy is taken.
How to use dairy correctly
Choose unsweetened milk and yoghurt, and eat a moderate amount of cheese with main meals instead of snacking on it all day. For young children, do not let them fall asleep with a bottle in the mouth, and always clean the mouth or brush before bed.
