I saw this on a previous question you answered, and have a further question about it:
"there can be other reasons for sensitivity other than decay. one is simple gum recession. it will cause sweet and cold sensitivity. a crack will produce cold and chewing pain. decay is usually cold and sweet pain. a nerve issue is usually heat pain and spontaneous pain"
What if someone has sweet and chewing sensitivity, but not cold/hot or spontaneous pain? Went in for a tooth cleaning (and got a clean bill of dental health from the dentist) less than 2 weeks ago, and now a little bit of pain is popping up. Once with something sweet, and twice with chewing. He did say that I grind and have some wear, so I wonder if it's from that. I need to get with my orthodontist about a night guard to replace my overnight retainer.
grinding can cause some chewing sensitivity...kind of a soreness when you chew, not a sharp pain. the sweet sensitivity can be some exposed dentin or root surface. i would look into the night guard to help take some of the stress away. and maybe try a desensitizing toothpaste like sensodyne to help out with the sweet sensitivity. good luck
