Ask the experts: The effects of soda water on your teeth
Q: “I’ve read in your magazine that soda water is bad for our teeth. I care madly for my teeth, so would trading in my soda water for sparkling mineral water be better?”

A: Accredited Practising Dietitian Zoe Wilson responds:
“Any drink that is carbonated is slightly more acidic, so it may affect your tooth enamel and increase your risk of cavities.
Sparkling mineral water would be a better choice, as a study in 2001 actually found that with mineral water, the effect of the acid is very minimal.
This is thought to be due to the minerals like calcium that are found in sparkling mineral water. Scientists believe these form a buffer and protect your teeth from the acid that is formed during carbonation.
Remember though, tap water is your number one choice as it also contains fluoride ñ which is important in helping to strengthen your tooth enamel.
If you’re not keen on drinking water as is, try making it a bit more exciting by keeping it chilled, then adding a squeeze of lemon or lime, or some mint sprigs for extra flavour.”
