Soft drinks and acid erosion

Soft drinks and acid erosion

We all know that soft drinks aren’t good for your health. Some soft drinks are high in sugar, and even the sugar-free versions contain acid that can erode your enamel. In this post, we’ll examine this topic further by answering some of your questions about soft drinks.


Why are soft drinks bad for my teeth?

Soft drinks are bad for your teeth because they are high in sugar and/or acids. Sugar is harmful because it encourages bacteria and plaque, which in turns causes cavities. Acid is harmful as it erodes the enamel (the outer layer of your teeth).


Is diet cola better for my teeth than regular cola?

Diet drinks, such as Diet Coke and Coke Zero, are indeed better for your teeth than regular cola. A can of cola contains a whopping 33 g of sugar, while diet cola is sugar-free. So, yes, the sugar-free version is better for your teeth than regular cola.


So diet cola is okay for my teeth?

No. Although diet drinks are sugar-free, it doesn’t mean they’re good for your teeth. This is because all fizzy drinks contain acids that erode the enamel on your teeth. Even sugar-free drinks contain these acids. Therefore, it’s best to limit your consumption of all fizzy drinks.


Which other drinks are high in acid?

The following drinks are high in acid: carbonated drinks such as fizzy pop, white wine, cider, alcopops, some sports drinks, fruit teas, juices made from citrus fruits (e.g. orange juice and grapefruit juice).

In addition, some foods are acidic. These include citrus fruits, such as lemons, oranges, blackcurrants, and grapefruits. However, the benefit of these healthy citrus fruits for your overall health, outweighs the negative effect of tooth erosion.


So what’s the best thing to drink?

The safest drink for your teeth is still water, whether it’s from the tap or from a bottle. Still water is pH neutral which means it reduces acidity in your mouth.

Though of course it would be a boring life if water was all we drank. Alternatives to water are sugar-free squash, diluted fruit juice, tea (without sugar) and coffee (also without sugar). Although these drinks don’t benefit your teeth, they don’t do much harm either.

Try to avoid drinking large amounts of fruit juice. Even though fruit juice has a reputation as healthy drink, it’s actually quite bad for your teeth as it’s high in acids. A good idea therefore is to dilute your fruit juice with water.


How can I prevent tooth erosion from getting worse?

If you already have enamel erosion, then the bad news is that it isn’t reversible – you can’t get your enamel back. However, you can stop it from getting worse and your dentists may be able to protect your teeth with a protective filling or crown. Here are some tips on how to prevent erosion from progressing further:

  • Limit your intake of acidic drinks and foods
  • Don’t brush your teeth too soon after eating acidic foods. Acid weakens enamel, and if you brush them when your enamel is weakened, you could damage your teeth.
  • Don’t drink acidic drinks before you go to bed. The acid will linger on your teeth during the night and weaken your enamel.
  • Talk to your dentist or doctor for help or treatment.
