Hope someone can offer some advice regarding my dental crown and post fitted into root canal.\nIt’s come loose yet again and I’ve been told the tooth is fractured below and I need an implant. SEE ATTACHED PIC\nI’d like to avoid an implant and persevere with the crown and post.\n\nHow did it become fractured? I do not know for sure except to say it may have been fractured from the very start due to the whack in my mouth.20 years ago.\n\nI’ve been warned of bacteria entering where the fracture is and it causing problems, but if the fracture happened 20 years ago over that period bacteria has not caused a problem yet so am ignoring the “be afraid of bacteria so you better get an implant” argument. Even so, the fracture is well below the gum line and it has not been explained to me how bacteria can be an issue other than the argument just , well, simply sounding right. After all, can’t bacteria enter down into where implants are installed anyway?\n\nDentists have cleaned out the canal before re-cementing on previous repairs. I guess this makes the canal that little bit worse-of-a-fit each time this happens. The last two times the crown and post have loosened after 8 and 4 months. Previously it lasted many years before coming loose. Even with the fracture , if the canal is the right fit and the right glue is used it should stay stuck. One dentist I asked couldn’t tell me how the fracture relates to the post coming out.\n\nSo, what to do? A dentist simply cleaning out the canal and re-cementing will most likely result in a loose crown again. Unless they use a different type of glue? Or,\n\nI can recommend other techniques. Perhaps use a filler down the canal and re-drill a nice fitting hole to refit the post . Or drill out a slightly bigger hole and remake a new post for the crown that fits better.\nCan anyone recommend another method to make the crown and post stay in? PIC ATTACHED.
