I understand your frustration. We, as dentists, need to give patients more information on what they can expect from dental work.
1. The quality of the car. A Honda is expected to last about 200,000 miles, but a Kia will only last 163,000.
This means the quality of your dental work makes a difference! The dentist has control over this part. So please don’t get upset when we send crowns back to the lab or redo something! Most dentists want to do quality work and they take pride in their work. Choose a dentist that you trust, pay them a fair fee, and allow them to do their best.
This means people who grind their teeth, drink soda regularly, and/or chew on ice will wear their dental work out faster than people who don’t do those things.
I hope I helped you figure out why the crown only lasted 6 years. BTW, that is not a terrible length of time. Keep in mind that even your dental insurance company will cover for the replacement of a crown every five years. My personal goal is to make sure my work lasts as long as possible. However, I only have control over the quality of the work I put in – the rest is up to the patient.
