Today I consulted with my dentist. Need wisdom teeth removed but seemed pleased with the health of my teeth (I don't use tooth paste or fluoridated anything for the past few years, go figure). He also recommended 6 month braces to fix crossbite in my molars and straighten front teeth but it can require wearing retainer for life.

Now I know crooked teeth can be result of poor diet I had growing up. I'm wondering that with my improved nutrition my teeth will stay straighter without the need of a retainer.

Thoughts?
