I have cracked teeth due to deep filling in molar. Sensitivity and pain 6 weeks later. Bonding or crown?

The best way to go is with a crown , a filling would not work , its not as strong and molars are the strongest position for masticatory forces.a crown can be made in 1 visit , and will give you a good solution , and you would not present sensitivity no more.

I would encourage you to go ahead and get a crown on that tooth, if indeed, it is cracked.  If you go with bonding (to save money), you can risk fracturing the tooth more, then needing to have the tooth extracted and replaced with a 3-unit bridge or an implant.  I know that crown may seem expensive, but it is your least expensive fix in the long term.  Good luck and I hope this helps.

A permanent crown is the answer to your question. It is the most predictable answer to your question. . This will have you chewing at a 100%. It sounds like a filling will not be enough for that tooth. You may also need a Root canal on the tooth depending on the extension of the fracture.
