"Oh it's just sensitive, brush with this expensive toothpaste."
Front teeth have some damage from drinking acidic drinks? You can get a custom mouth guard so you don't grind your teeth.
There are toothpastes that help with sensitivity but they shouldn't be that much more expensive. At least here they're not over 1.5x normal toothpaste or so. (If I remember correctly)
The acidic drink stuff could be, but you shouldn't be drinking sodas in general, they are bad for you indeed.
The mouth guard thing, they have the exact same line here too! Hah! I never bought it.
I don't think I've had new cavities in 15-20 years. Pretty much since I was a retarded fat ass teenager eating too much sugary crap.
Btw, it sounds kind of weird to just go to the dentist because "you were summoned". I mean, go for some yearly plaque removal and checkups sure, but other than that, if you don't have any issue it's kind of weird to go for no reason. My regular place would call me sometimes if I hadn't gone in too long, but usually I'd say I'm busy and not schedule an appointment.
PS, you don't need xrays to see cavities. They're on the surface. Although it's hard to check your own teeth without mirrors and such, but any dentist should be able to identify them at a glance.
EDIT: I just remembered something very important:
