I recently got my braces off, June 30, 2014. One of my teeth at the top isn't flush with the rest like it was the day I got my braces off. Dentist told me I have to wear my retainer all day ever day for 6 weeks straight. Then I can switch to only wearing it at night and by the time the 6 weeks are over my tooth should go back to being flush. However, Ive been wearing all-day like the dentist said I should. But when I wake up in the morning it appears I had spit my retainer out and it's always tight on my teeth. This has happened 3 times already. Should I ask my dentist about getting a permanent retainer?
