Fructose is sugar. Bacteria use these, and form acid. Acid erodes teeth.
I'm not talking about the surface so much as the living inside of the teeth. Fructose is only going to be a danger to teeth if they are weakened by an acidic metabolic state, which is what happens if eat acid-forming food from morning to evening.
Teeth rot ( faster) if the body is constantly acidic, because the ( alkaline) calcium which keeps them strong/resistant to surface acid gets taken away by the body to balance up the acid.
Cutting white sugar out completely is also good cheap dental care. But if it is already too late, and caries/rot has started, and teeth are aching, eat nothing acid-forming before midday, and as little as possible ( acid-forming ) the rest of the time until are better. Fasting for a couple of days does wonders.
