Evergreens such as spruces and pine trees are a rich source of vitamin c, and were valued as such by Native Americans. These sources were assuredly available most the world over where winter occurs, so presumably Europeans knew of them too.

As for sugar:
Tooth decay is caused by acid-producing bacteria in your mouth that feast on carbohydrates, be it sugar from candy or starch from wholesome foods such as bread.

Potato chips and raisins cling to your teeth, giving the bacteria something to savor. But a simple chocolate bar can get washed away naturally with saliva. The faster a food is removed, the less chance it will have to feed bacteria and cause decay

Plenty of preindustrial foods were worse for your teeth than candy
