Sour sweets can be very damaging to tooth enamel.

Eating lots of sour sweets is like bathing teeth in battery acid, one US dentist has claimed.

Dr John Ruby at the University of Alabama School of Dentistry noted when eaten, the pH of some sour sweets can be as low as 2.2.

Considering that neutral is 7.0 and battery acid would have a pH of 1.0, it is plain to see the damage these sweets can cause to teeth.

However, he noted that eating them in moderation should not be too bad and for people who want to limit the damage they cause their tooth enamel after eating these sweets, Dr Ruby had a few tips.

He noted: “You can drink milk. Swish your mouth with water. Eat cheese. So you want to do something to neutralise that acid attack. But don’t go and brush your teeth right away.”

Elsewhere, the Coloradoan recently reported developing bad breath could be one of the first signs that a person has poor oral health and could be a symptom of a more serious problem.
