dentist checkup

So i went to the dentist today to get my teeth cleaned. i waited for about an hour, even though it wasn't that busy, like not a lot of people, so i don't why. Well when the doctor came she looked at my teeth and i have TWO CAVITIES, one is big and the other is a little one. Then she found out that i haven't had a x-ray in six years, and she said i'm supposed to do it every three years. So we did that just to see if i had any deep cavities, which i didn't, and my bone structure was good. The only concern were my wisdom teeth, none of them have been exposed to the surface yet, they're still under the gums so my left side has a chance of growing out and if it does I have to get surgery to remove it since it'll just create a pocket and get infected easily, but the doctor said there' a low chance especially since it's been like that for over a year now. I have to get my cavities filled in two weeks, but it's no big deal since they are just surface fillings and I already have had like five fillings. Just have to watch out for how much sweets I eat and floss more often, then everything will be okay, at least I hope...
