Teeth problem

I had a root canal done . I was told i cant get it filled until the dentist said so . I kept going back to the same dentist for cleanings and what not , and every time i asked when i can get it done . He said not now . We have to wait a while . Well , i just checked my tooth and its cracked . Which i was told what would happen if i waited but i did what the dentist told me . Now i will have to remove it and shit . i am beyond pissed . i tried to prevent thus . Not like i'm trying to but can i sue for this ? Or cause a problem being like "i tried to get something done and now i cant because YOU guys told me not to get it filled" . I am so angry . I cant even explain . and i also saw a couple hole/type cracks really tiny in a couple other teeth . What should i do ? What can i do ?
