Thanks so much for your videos. I’ve been binge watching because I’ve had multiple issues that have required different treatments. I started having sensitivity to cold on the backside of a tooth immediately after a filing was done on the front side. Do you think having the cavity filled caused this?

A while ago I noticed some kind of darkish line on my top tooth (looks like there’s some kind of shadow under it?) I’ve also had a filling here previously.
After this I had tooth pain in that tooth and the top side of my teeth, this pain has been on and off for around 2 weeks, some days pain some days none at all. The tooth pain usually comes with a headache as well.
After I went to the dentist they took 2 X-rays and said she saw nothing and gave me some toothpaste for sensitive teeth. (Said something about it being a possible pressure overload?)
Problem is I still have pain after using the toothpaste for a week but shouldn’t these cavities be visible on the X-ray?

Hi Fanta. Sorry to hear about your toothache. The answer to your question is that no, not all toothaches are visible on X-rays. In fact, several times a year I have to treat a tooth that appears perfectly fine on the X-ray. This could be either due to a crack, which is not visible on most X-rays, or a small decay that goes unnoticed on X-rays (think of a little dot like melanoma that goes deep into the nerve). Pain is the determining factor in these situations. Your doctor needs to do a few tests (cold, tapping, etc.) to see if he or she can narrow down the pain. If so, then you may need a root canal, or even have to pull the offending tooth. I recommend you get a second opinion. The type of pain you're describing is not a sensitivity pain can be treated with Sensodyne. You most likely need a root canal or tooth removal.
