I got a porcelain crown 3 weeks ago and the back broke off 3 days ago. The damage cannot be seen. I have had a root canal and am in no pain. There is a dentist I can see in Kabul but I am not sure that he has the necessary resources to order a good crown. I have the part of the crown that broke off. Someone offered to get a dentist to come to see me to glue it back on. I can only leave to get this fixed in 6 weeks. Can I wait until then if I use mouthwash after every meal?Thank you
