Finally happy too know I’m not alone just like one of the guest on here my itching is in my two front bottom teeth. I have to dig my nails into them to subside the itching, a great sigh of relief. I even use my tongue to try and starch the spot this has been going on since I’ve been in elementary school and I’m 20 now. I have never told my dentist because I thought it was just me even though my teeth are healthy. I will be overwhelmed when somebody finally figures out what causes this. For now I’m going to take the advice on not bothering them and see how that works out.
