Fruit juices could harm tooth enamel.

People should not drink too much fruit juice as it could harm their teeth, it has been claimed.

The Muslim News reported the pH of many fruit juices can be quite low and this can lead to the erosion of tooth enamel, which in turn could result in a problem with cavities or decay.

According to the publication, there are a number of simple rules that can help a person maintain a healthy smile.

These include not drinking too many fizzy, carbonated drinks and being careful about eating acidic foods – such as citrus fruits or sour apples.

They should also wait 40 minutes after eating before brushing their teeth and chew sugar-free chewing gum to help boost saliva production.

Elsewhere, WCCO.com recently reported Dr John Ruby at the University of Alabama School of Dentistry has called for people to reduce the amount of sour candies they eat, as when tested, these sweets can create pH levels in the mouth that are almost the equivalent of battery acid.
