I went to the dentist yesterday convinced that I had a few pretty bad cavities due to the fact that it's been 6 years since my last visit. My teeth have also been very sensitive to sweets and cold temperatures...specifically 2 teeth. I had X-rays taken of my teeth and according to those, I only had 4 very small cavities in between teeth. I mentioned the issues I've been having with my teeth to my dentist but she didn't seemed too concerned. After my appointment I also realized that my dentist never actually looked at my teeth...just the X-Ray. And the Hygenist didn't even bother looking/cleaning in the pits of my molars. Is it possible for cavities to not show up in an X-Ray? I've attached pictures of what I believe are cavities in my teeth. If someone could look at them and give me their opinion, that would be great! Thanks!
