There are several options that you have posted and I don't know which one to go for, which of all the ones you have posted is the best dental clinic?, I need to go to one, a tooth has been bothering me and I know I need to get that checked out soon.

I have also heard about the salt method, I will try it on my work clothes to see if it really works, if my clothes from going to work every day don't fade, then I will be sure that it works.
