They may make your lips pucker, but sour candies can do more than surprise your taste buds - they can seriously damage your teeth, experts warn.

"These candies combine two factors that increase mouth acidity and accelerate enamel erosion," said Nadine Tassabehji, an assistant professor at Tufts University School of Dental Medicine in Boston.

While all candy can harm teeth, sour candies are especially destructive because of their high acid content. Common ingredients like citric, malic, tartaric and fumaric acids make these treats extra lip-puckering and extra harsh on tooth enamel.

When you eat sugary foods, the pH in your mouth drops and becomes more acidic, Tassabehji explained.
