I have a cracked molar (fractured cusp) along with a vertical crack running down the middle. Crack is from having a large filling. Dentist says my roots are healthy, but is unsure of treatment. He suggests a crown, but because of the way my tooth is cracked, he can't guarantee I won't have issues with it down the road. I am now experiencing bad breath, so I am assuming there is decay within the crack. Should I have it pulled? Get the crown and hope it works? Money is also an issue.
