Nighttime snacking could harm teeth

June 2, 2010

Researchers at the University of Copenhagen blame the problem on changes in saliva flow, which tends to dry up at night.

Adequate saliva is needed to help remove food particles found in the mouth. If food sticks around, it can cause damage, and experts say a drier mouth tends to accentuate the impact of sugary and acidic foods and drinks.

According to findings in the Journal of Eating Behaviors, nocturnal eaters ended up losing more teeth than those who stopped eating earlier in the day.
