Apr 25, 2016 · Should I Be Worried about my Worn Teeth? In this post, I’ll talk about what those risks are and how you can protect your teeth, as well as how teeth get worn down in the first place. How Do Teeth Get Worn Down? There are a number of reasons why teeth become worn over time. Normal function (eating and speaking), and some diets promote 5/5(35). Enamel is the thin outer covering of the tooth. This tough shell is the hardest tissue in the human body. Enamel covers the crown which is the part of the tooth that's visible outside of the gums.
Another phenomenon that's often seen with teeth that have worn down due to tooth grinding is chipping. Enamel is a strong dental tissue but it's also brittle. If it's worn down to a very thin, sharp edge, tiny fragile bits of it will tend to chip off. When you have them regularly, “this exposes your teeth to acid for a longer period of time, which wears down the enamel,” says Sara Hahn, DMD, an assistant professor at the University of Author: Sharon Liao.
2. How teeth can be worn down by other teeth. Attrition is the mechanical wearing down of the biting and chewing surfaces of teeth. The tooth to tooth contact during chewing grinds down the surfaces. The back teeth become flatter, and the front teeth become shorter.
