I have been having severe toothache from past two days.I don't have any cavities.The tooth is the left incisor from front incisor in the upper jaw.I couldn't properly sleep in night because of it.I visited dentist yesterday and he said that I might have any sort of injury due to eating hard things or playing 2 years back.I had hit the upper jaw and had pain in the same tooth.The dentist has given medicines and has suggested to wait and watch or otherwise if no relief ,RCT will be performed.
