Are ‘healthy’ foods and drinks damaging your teeth?

  • By Regenerate Enamel Science

Many foods and drinks have healthy associations, from the Vitamin C content of oranges to an apple a day keeping the doctor away. Many people also swear by their morning lemon water fix as a digestive aid. However, it’s worth thinking about your dental health too. Read on to find out how ‘healthy foods’ and drinks could have a negative effect on your oral health, and what are the best alternatives.

Is lemon water bad for your teeth?

Lemons (and limes) are the sourest taste most of us will experience since they’re the most acidic fruit. And this is precisely why lemon water is bad for teeth.

Acid attacks the hard enamel surface of the teeth, making it wear down. This is known as acid erosion, and the enamel erosion it creates is one of the leading causes of tooth sensitivity. 


Is lemon juice bad for your teeth? In large quantities, yes, so you’ll definitely want to consume this fruit in moderation. However, starting your day with a glass of still water and drinking plenty of liquids throughout the day is a good habit for keeping your body hydrated.

Fruit and juice, and oral heath

Fruit juice seems like a healthy drink, but is juice bad for your teeth? Certain acidic fruits fall under the category of foods that damage teeth, and their juices are damaging too, for the same reasons that lemons are. Cranberry juice has an acidic pH value, as do grapes, pomegranates, grapefruits, oranges, and pineapples. Even apples, peaches, mangos, and blueberries are on the acidic end of the scale.


There are many ways to combat the acidic effects of fruit on your teeth:
  • Consume acidic fruit and juice in moderation. 
  • Try switching between eating acidic healthy food that could be harmful for teeth and their less acidic alternatives, such as bananas, watermelons, cantaloupe and honeydew melons. A balanced diet is key for healthy teeth and body.
  • Drink fruit juice all in one go, rather than sipping at intervals. 
  • Drink juice with a straw to avoid direct contact with teeth.
  • Rinse your mouth with water or drink a glass of water afterwards to dilute the acid.
  • Avoid brushing for at least 30 minutes after eating or drinking to minimise the potential for enamel erosion.

Are sugar-free drinks bad for your teeth? 

Fruit juice can be bad for oral health, and the same can be said about sugar free drinks. Many of these ‘healthy’ drinks actually contain citric acid, phosphoric acid, and tartaric acid, all of which can damage teeth.


Switch to drinks that don’t contain as much acid, like milk if you tolerate it well and, of course, water.

Red wine and oral health

Much has been made of some of the health benefits of a small glass of red wine. However, if you sip wine to make it last, you’ll experience the same issues as with lemon water, because wine is acidic. Nevertheless, it’s important to consume any alcoholic beverages in moderation.


To counteract the acid when you drink a glass of wine, drink water with it. There’s also a dental benefit to that popular wine accompaniment, cheese – it can help lessen the acid by raising the pH level and increasing the saliva in your mouth.

Consumption of acidic foods and drinks, like the ones mentioned above, can lead to enamel erosion, which in turn causes 80% of common dental problems like tooth sensitivity and eventual damage.
