In Jan. I had my upper front six teeth crowned, all at once. I have been having a feeling of my teeth loosening, especially in the morning, they don't exactly hurt, they are just very sensitive, not only the teeth that are crowned but all my teeth. Is this normal after so many crowns, if so how long will this feeling last? My gums feel puffy, but not discolored, when flossing I do have bleeding around some of my new crowns. Any advice?

Yes. Go back to the Dentist or go to another Dentist. I've had crowns, but never six at once. This could be a problem, including infection.

You need to be seen and treated.

Why Mexico?
