Honestly, I think it's all a racket. I went 24 years without having my teeth cleaned, because when I was a kid, dentists didn't clean teeth; it was unheard-of. THey just didn't do it. I do have quite a few fillings, but my guess is that everyone in my age group has far more fillings than younger folks, because dental hygiene has its place. However, twice a year at $300 each is extreme, I think. I have dental insurance, but all it really covers is two cleanings a year, and a small portion of other things (yes, it's Delta). It only covers me. It would be about $2000 a year to put DD and DH on it, and it'd still only cover a portion of things after a one-year waiting period. Our compromise on dental care is insurance only for me (because premiums are free through work), cleanings for everyone once a year, and wait until you get a toothache to have something done. So far, DD has needed only three trips to the dentist in her life (she is 20)- once for sealants, once for a filling, once for a toothache that resulted in having a baby tooth taken out. DH needs to have a crown replaced; work was originally done 20 years ago in San Francisco for $50 (he had good insurance), he had it replaced about 3 years ago at Aspen Dental and they botched it, and he needs it taken care of now. I think he's just going to have it pulled; it's a lower molar, he has another behind it, and his lower jaw is crammed with teeth (no braces). He could have a root canal and crown for about $4000, or have it pulled for about $400. THere's plenty of teeth down there and he figures if things shift after the extraction, he won't have crooked teeth anymore!
We are actually very happy with our dentist. He understands that dental work is expensive and didn't balk when we took DD for cleanings at the local dental hygiene program, where it was $30 and you got a student AND a hygienist to do the cleaning. On my last trip, I asked about my 40+ year old silver fillings, thinking they'd need replacing soon. He hemmed and hawed and poked around, and pronounced them sound and not needing replacement unless I really wanted them done! He also said that my chipped crown is going to be really difficult to fix, but that it, too, is sound, and if I didn't mind, he'd prefer to file it a bit to smooth one edge instead of replace it. Yes, I am a happy girl, because with Delta insurance, I'd pay about $85% of all this if I had a dentist who believed in treatment plans! I guess we are lucky that we've found a dentist we like and trust, because I know the shysters are out there (ASPEN DENTAL)!!
