I had root canal treatment yesterday, and whilst the treatment went well i have a temperary filling and crown and need to have it finished next week. This is because my dentist said the roots are very long, she actually shown me the Xray and they practically come to the bottom of my jaw line. So more prep is needed.

Now to my concern: after the treatment everything was fine with no pain, however this moring i have woke up with quite a sensitive tooth, it’s not painful in general, just when i bite down. Is this normal, And can having such long roots cause more serious problems in the future? My dentist seemed quite….not concerned but well a little bemused!! Don’t get me wrong i like my dentist she is very patient with me as im a very nervous patient, i would just like a specialist opinion.
