To be pissed off with old dentist?

[ImLadybird]

AIBU to be really upset this wasn't picked up on years ago? DD19 went to dentist (who we've not seen before) for check up this week and was told she has a cross bite. It would need braces and possibly extractions and surgery to correct it. What pisses me off is that we specifically asked last year and the year before if her jaw is ok because it has looked crooked since her wisdom teeth started to come through, and we were told it was fine. This week's dentist said it should have been done at 14/15 and that she's now 19 is why surgery is more likely. He said it wasn't essential for her dental health but I'm worried there will be problems down the line if we don't correct it now. He's referring her to an orthodontist so we should get a better idea of what's needed and can make an informed decision.
Almost all her friends had braces at 15 so she wouldn't have minded then and it would have been easier to fix. At 19 she doesn't want braces for two years and she's horrified at the thought of surgery. But she'd have a lovely non-crooked smile in two years and now she knows it's as bad as it is, it's bothering her more than ever.
I feel so bad I didn't realise there was something wrong sooner. It's her bloody smile ffs. And how much of a fuss should I make with the dentist who failed to detect it previously?
WWYD?

It's not the best photo but gives you an idea...

As you 've said it wouldn't impact on her dental health it may be wasn't a clear cut decision.

If it was deemed cosmetic it nay not have met criteria for referral at the time.

If it's on the NHS then it would only be referred to the orthodontist if it was going to affect bite/eating, not just cosmetic issues. So it was probably one of those situations where it was a close call whether it counted or not. Or perhaps the dentist knows the ortho they refer to would have kicked it back because they're very strict on NHS work. (I used to work in this area)

You often get differences between medical professionals - I was told by one German doctor that my iron levels were catastrophically low, and my cholesterol so high I should be on statins, only to be told in the UK that both were safely within normal limits!

Braces as an adult aren't too bad. You can pay to get clear ones. I had braces (coloured ones) for 7 years, including the entirety of college and uni, they were removed the day before graduation. Not one person ever commented on them.

Thanks. I appreciate your input. I would have considered paying for it so if it wouldn't have met NHS criteria that's fair enough but we should still have been informed that there was a cross bite and it could be corrected.

That's reassuring Herbie, thank you. I feel a bit better!
