I'm quite puzzled.
I went to 4 dentist lately.

1: It's all right! Cool!
Then I come home and upon close looking I find a small cavity which he
then agreed to treat.
2: Oh, well, there's an infra-dental cavity here, let's treat it!
He saw it by looking at the 180degrees x-ray which also the former
looked at without seeing anything.
3: (after treatment) Ok, but we mush extract both wisdom tooth.
4: We must extract 1 wisdom tooth, see, there's a cavity there (showing
it to me with a probe camera.

So, I'm a bit underwhelmed by this lack of consistency.
In the future, how can I rely on someone to see any cavities if everyone
missed one at least?

Then maybe is be best to rely on myself: but is there a way i can check
myself for intra-dental cavity?

Please note that the 2nd one saw a cavity on the x-ray which I'd never
imagined to be there. Still I can't see it on the 180deg x-rays. But it
was quite apparent on the small x-ray he made for confirmation.

Thanks.
