My lower right first molar was canalled about a year ago. I couldn’t get a post and crown put in because it was fractured. The dentist bonded the tooth instead. I looked closely at the tooth in the mirror and I saw a line underneath the biting surface. Last week, the dentist filled a small area of the tooth. I was really wondering how long a tooth “bonding” would last. I have heard it chips and peels and should be redone after 2-3 years. Will my tooth fall off? It was fractured but it ‘s not bothering me with any pain or discomfort. Has anyone else had bonded tooth? How long did it take before it has to be redone? I would be thankful for any input.
