Re: Going To The Dentist - First Time In Ages...
Most likely they will extract your wisdom teeth before doing braces, and the baby teeth. My son is going for braces soon, and they took out his remaining baby teeth, so the permanent ones would be coming in around the 6 months for braces. I myself, had teeth extracted before braces, and my wisdom teeth extracted after my braces (for the fact they were impacted and causing crooked teeth on my bottom jaw after years of braces *sigh*)
The bad breath I agree with ysco, can be due to an infection, periodontal disease of the gums and gingivitis. Same for the whitening, especially since you have quit smoking.
