Have a dentist visit tomorrow. I will ask him.
Not using would be the biggest thing. 10K of dental work and continue useing could be throwing 10K away in my opinion.
I have 4 caps (not from drugs) and they serve me very well. The cost is the biggest issue but well worth it. Broken teeth repaired did wonders to help my smile and my selfesteem. More then I ever thought it would...yes well worth the $$ in my opinion.
