I don't have great teeth, primarily because of a horrible fear of going to the dentist. I had a root canal done about 13 years ago, but I couldn't afford the crown at the time (I could barely afford the root canal) so I just let it be with a filling. Well, that was not a good idea - the filling fell out but I still didn't go to the dentist. About 4 years later I found who I thought was a wonderful dentist. The tooth had a huge cavity now (shocker!), but he still tried to save the tooth. He cleaned out all of the decay and what was left of the tooth was almost paper thin. He put a crown on it anyway, using a brand new procedure in his own office (before, he would do impressions and order the crown through a different company). It didn't save me any money, and my insurance at the time would only cover about 10% of crowns, if even that I can't remember exactly, I just remember it cost me about $2,000. I should have questioned what he was doing and asked for a discount or something, because I completely blame him for what happened next (at this point he should have told me to get it pulled IMHO)...
Less than 3 month later my DD and I were at the Olive Garden and I bit into a breadstick. The tooth broke off just above the gum line and took the crown with it. Luckily I noticed right away and didn't swallow anything. There was nothing else that could be done after that but get the tooth pulled. They put me under, and after the procedure the oral surgeon told me he was glad they put me under because he had to dig pieces of the tooth out it was so damaged. Eek. Before I even got the tooth pulled my dentist was telling me that he was looking at doing dental implants in the near future and to have the oral surgeon prep me for an implant, but to go back to him for the actual implant. I found that shady and never went back to him. I didn't like the constant trying to make big bucks off his patients, especially being I was a divorced mother not making a lot of money at the time.
I started seeing a new dentist right away and she explained to me my options (implant, bridge), and warned me what might happen if I do nothing with the empty space (teeth on top may lower, teeth on bottom may shift), and never mentioned anything about it again (in the 5 years I've been seeing her).
It took awhile to get used to the missing tooth - I almost choked on food that wasn't chewed enough many times. But now I barely notice it's missing. I can chew on that side of my mouth like normal and none of my other teeth have started moving.
$2,500 is a lot of money, and had my original dentist warned me that it could fail I would have never gotten the crown. I know, dentists want to save teeth, but there comes a point when it's not the best choice for the patient.
