Pronunciation

Now, I have my teeth straightened. I think Japanese (include Asian) doesn't have the habit wearing braces.
Firstable, I wore an orthodontic appliance above and behind a row on my teeth for extending.
After that, I couldn't pronounce many words.
But yesterday, it was happend after 8 months, the dentist took of it!
I thought the world is really wonderfull! I can pronounce any words!
Hip, hip, hurray!
Definitely I need to wear two orthodontic appliance over my teeth at least 1 year.
Gee...
