Severe toothache upper left molar. Food!

First query is : is it a particular tooth or all the teeth in general ? 1. If it is a particular tooth - probably the nerve of the tooth (pulp) is exposed and involved so the treatment will be either root canal or extraction depending upon the case 2. If its teeth in general - there is a high possibility according to your age that abrasion has taken place i.e teeth have worn off resulting in exposed dentin and pulps of several tooth . Treatment - take an OPG ( full mouth X-ray) and evaluate which tooth have can be saved with the help of simple restoration(filling) which one have to be removed and which one have to undergo root canal therapy 3 another possible reason is due to grinding over the years all your teeth have got attrited ( become smaller in height) and thus while eating food you are putting excessive force to meet both your upper and lower dentition thus resulting in pain n sentivity Again treatment can be evaluated after taking opg and probably if you are keen one can either go for esthetic and functional treatment option of veneers or if the teeth are sound and solid one can go for overdentures after rc therapy
