Do fruits cause tooth cavities?

Not usually: Most fruit sugars, in their natural whole form, are offset by the fiber present. Simple sugars are much more prone to cause cavities.

Possibly: Hi! simply, the bacteria within the plaque on your teeth use sugars (including fructose) in a metabolism process called glycolysis, to get energy. The end product of this process is acid , which can breakdown the calcium phosphate in your tooth to start a cavity. This is why it is so important to remove the plaque on your teeth daily. Some fruits are acidic too which the damaging bacteria loves.
