    Hi

    My dentist discovered I had a craze line on lower molar towards end of last year (had a fractured tooth opposite side same tooth discovered eventually earlier that year - long story resulted in infection wouldn't clear, root canal attempt wouldn't clear and then it cracked through another attempt when clearing the canals, so tooth extracted, resulted in a lot of bone loss). Now with that history I asked if this tooth could be crowned now due to previous experience, was told no wait and see craze lines are common.

    8 weeks later back to dentist with that tooth tender and earache and insisted on xray - confirmed early stages of infection. I pushed for a crown to protect tooth.
    Antibiotics cleared infection then was booked in for crown. 1st visit no infection present so tooth was prepared, filed down and shaped, visible crack across tooth so was told this was the best option. Took impression and said I could go and rebook for 2 weeks. I asked was I not getting a temporary cover to protect tooth and was told no, it's in a better position now as the tooth sits lower than other teeth so won't get knocked it'll be fine. Was told to be careful and eat soft food nothing too hot or cold on opposite side.

    Had crown fitted 2 weeks later. Had to polish off upper teeth to accommodate the bite. This in itself has left upper teeth feeling weird and sometimes achey.

    Anyway have had trouble on and off with crowned tooth being sore and one point loose. Went back several times to check the crown and was told it can take up to 6 months to settle. When it became lose went to an emergency clinic as couldn't see my dentist and xray showed nothing. It settled and became solid again. Waves of ok no pain no problems to not ok during this period

    Had a mouth guard made 3 weeks after crown to protect from clenching.

    At 6 month point I had a lump appear side of gum of crowned tooth. Went back and dentist said likely the mouth guard rubbing doesn't see it looking like infection. (prior to all of this my teeth were in perfect shape, no fillings, cavities, decay etc. It was a bout of high levels of stress and grinding teeth which caused the cracks in teeth). Guard checked and said yeap there is the rubbing and cut it to shape. I asked for xray and had one but dentist felt it unnecessary. Xray showed advanced infection. Two rounds of Antiobiotics did not clear, told root canal won't work so extracted tooth.

    Question, I was infection free before crown prep, the procedure for crown, should a temp cap/cover be fitted as standard to protect tooth, especially knowing my history with other tooth and there was a visible crack across the tooth when he wore it down? I did question couple times at the time are you sure and dentist convinced me I would be fine. Not being a dentist and unfamiliar with procedures accepted what i was being told.
    Is it likely that the bacteria got in whilst exposed for those 2 weeks and caused this infection which has now results in this loss?

    Not particularly happy as thought crown would prevent infections and further damage.

    Based in UK.

    Thanks

    If you had infection at that stage, then that's when the RCT should've been done (or an extraction). It doesn't make sense to take antibiotics to settle the infection (they didn't clear it), then progress to crown. The fact that you could go without a temp crown but no pain shows that the tooth was probably dead and infected already.

    Thanks for reply

    Antibiotics for 5 days following extraction and going back because still badly infected.

    I feel this could have all been avoided if the tooth was crowned when I asked last year.

    Maybe, maybe not. A crown preparation can cause nerve death in 5-10% of cases anyway. On one patient, I had all 3 teeth die after crown preparations, and I was being as conservative as possible. That could also have happened to you. The dentist is also to be judged by their peers, not by the patients. So if he had done a crown for a tooth that didn't show a clear need, he could be criticised by the dental authorities for any adverse consequences. I would probably not have done a crown for you either. You are unlucky, and sometimes s*** happens to both patient and dentist.
