Has anybody ever had root canal retreatment on the NHS? My dentist just informed me there are no NHS dentists in my county (Northamptonshire) that can do it under the NHS, previous referrals to MHS dental hospitals have failed apparently. My only option is to pay for it privately (different dental practice) which can cost up to £1000 or have the tooth out. Had toothache 3 weeks ago when I had covid and an abcess formed :(
