2 months ago i decided to have 2 new crowns for my front teeth for cosmetic reasons (#8 already post crown with RCT 15 years back). I am 39 years old. Following the crown procedure (2 weeks after) i experienced intermittent pain in the previously healthy tooth (#9) and had to embark on 3 weeks of treatment / draining etc. due to abscess formation. The tooth was left 'open' for 2 weeks during this time to to the infection which eventually subsided. The RCT on this tooth was finally completed 3 weeks ago and has been fine since then. However the past week i have started the feel the tooth 'pulsing' ie i can intermittently feel my heart pulse through it and it feels strange. I have no pain whatsoever just this 'pulsing'. Has anyone experienced this post - RCT? I am unsure whether i should return to my dentist to get this checked out.
