Hi . Good evening. As you mentioned the RCT was done 5 years back and you didn’t have any issue till of late, it’s my opinion that there should not be any issue with the RCT or the crown. The gums surrounding the next live tooth may have receded down exposing the fresh root surface which may be causing the sensitivity. However as nothing much can be done during the lockdown period, it would be advisable to use a desensitisation tooth paste like sensodyne tooth paste and avoid cold and too hot beverages and food till you find any dentist for help.
