An article featured in the Daily Mail this month gave insight into how researchers and dentists have recently started to fear that bottles water could be harming our teeth.

We have been warned for years about the effects of fizzy and dark coloured beverages such as red wine and coffee, on our teeth. But for the first time, research is showing that even bottles water could affect our teeth due to its pH levels

For the purpose of the article, scientists tested pH levels from 9 of the top selling water brands.

The pH scale ranges from 0 to 14 with 7 being neutral, under 7 alkaline and above 7 is acidic.

Tooth enamel can start to erode at pH level 5.5 and lower.

Surprisingly, popular brands Aquafina and Smartwater had pH levels of 4.

Volvic and Fiji water came in at 7.5 and 8 respectively.

To avoid enamel erosion because of constantly drinking low pH level bottles water, try drinking more tap water as this has regulated amounts of fluoride in it which is good for our teeth.
