The dentist told me I have torus palatinus, and I'm just wondering if it's dangerous?

Torus Palatinus. A torus is merely a localized overgrown of bone, completely benign, and definitely not dangerous. Since it is more pronounced than adjoining tissues and covered with a thin layer of mucosa, it may be more easily abraded by food. The main concern only occurs if one needs a removable prosthetic replacement for missing teeth and even then, it can easily be resolved.
Are not dangerous. The torus is a bony outgrowth in the mouth. Torus palatinus does not need to be treated since its essential features appear to be normal. If concerned, ask your dentist for more information.
Not dangerous. Your dentist should have told you that.
