What does sugar do to teeth?

Most people know that eating lots of sugar is bad for your teeth, but do you know why?! A lot of our patients tell us that sugar makes holes in your teeth but there’s more to it.


We all have bacteria in our mouths, some of the bacteria that live in our mouths are able to metabolise sugars to form acids. These acids break down the mineral content of our tooth enamel which can cause decay. Initially this starts as a reversible demineralisation process but if it progresses results in cavitation (decay) of your tooth structure which require restorations (fillings).


By reducing sugars in your diet, you prevent the bacteria from forming acids hence reducing your risk of decay. Of course, there are many other decay preventing strategies such as regular tooth brushing and flossing, use of fluoridated toothpaste and drinking fluoridated water.


Remember it’s not just sugary foods to limit, there are lots of hidden sugars in drinks too.

If you’ve indulged in a few too many sweets recently it’s a good idea to have a dental check up and ensure you haven’t developed any decay. If we catch it early, we can put some strategies in place to reverse your early decay!
