At the University of Birmingham, Catriona Brown put extracted human teeth without signs of erosion into jars for 30 minutes with different kinds of flavoured sparkling water to see what happened. The teeth had been coated in varnish, apart from a half-a-centimetre-diameter test area which was left unvarnished. They found the effect of the drinks on the teeth was the same and sometimes greater than the effect of orange juice, a drink which is already known to soften tooth enamel.
Lemon and lime, and grapefruit were the most acidic flavours, probably because they use citric acid to give the nice taste. Studies on this are few and far between. But in , the Birmingham team examined seven different brands of mineral water, again pouring them over extracted teeth to see what happened. They found sparkling waters had a pH of between 5 and 6 so not as acidic as some cola drinks which can be as high as 2.
In other words, they are a weak acid, as suspected. But when it came to the erosive potential of that weak acid on the teeth, the effect was times less than that of some other kinds of fizzy drinks.

The healthfulness of flavored water depends heavily on the types and amounts of ingredients it contains.
Flavored waters vary, but most consist of water, natural or artificial flavorings, and sugar or artificial sweeteners. Some also contain caffeine or added nutrients, such as vitamin C. Read the nutrition labels carefully to determine the ingredients of individual brands. If you are choosing flavored water to replace a high-calorie, sugary beverage, then it may be the healthier choice.
Sodas, for example, typically contain many calories due to their high sugar content. But some flavored waters also contain sugar and associated calories, so you must read the product label closely to determine if a particular brand is an effective low-calorie option. If the flavored water is replacing a nutritious drink, then it is a relatively unhealthy choice. Put in lemons, limes, berries, whatever you like.
Same goes for carbonated water. If you want flavor in your bubbles, add fruit to plain seltzer water. If you give up the artificial sweeteners for 7 to 10 days, fruit will start to taste sweeter — and your water with strawberries will taste even better. In some cases, Linge says, sparkling water may even help you stay better hydrated than you might with still water.
In one study of flavored sparkling waters, researchers found that the fizzy stuff can weaken the enamel on your teeth, likely due to citric acid contained in the fruit flavoring. If you do experience any digestion issues, though, consider flavoring still water instead to get the best of both worlds.
Linge suggests adding frozen fruit, herbs or a splash of juice to regular drinking water to create your own infused flavors.
