What would the process be to fix my cracked fake front tooth? What has caused this to happen?

I would agree with Dr Borowski overall--I tell my patients if God's dentistry doesn't last forever mine will not either--that said, a porcelain crown if that is what you have should give you years of service unless there is severe clenching or grinding causing it to flex and crack--hope this helps--Dr Merrill

Your question is difficult to answer without a picture. One thing I would say is that nothing in dentistry will last forever. I wouold return to your dentist and share your concerns about the fractures appearing in your new restorations.
