Do you need perfect teeth to become a dental hygienist?

No you don't have to have perfect teeth you just need an education. If you really want to do this then I'd say go ahead and maybe you will get to work for a dentist that can help get your teeth fixed. Think about it.

To become a hygienist is more focused on studies post high school. Level of education is more important. You can have work done slowly, bit by bit after you have been accepted. Some schools prefer you to complete dental assisting first.
