I am 62 years old. I just went to the dentist and was told that I needed to replace all my fillings since they are old and have some problems. The dentist said that since many of the fillings are very big, they will probably need to be replaced with crowns. I am willing to do the work but I need it to be spaced since I don't have insurance and my budget is very limited. I am new in the country and don't know if it would be appropriate to tell the doctor that I need the treatments spaced, so I can have the time to save for them. Any advice in how to deal with this situation. I am very worried.
