I need to have a dental bridge replaced.is it true that the 3rd time a crown is worked on, there is a greater change of ascess dental bridge was not made correctly. however, one of the crowns (abutment) previously had a crown and was replaced with bridge

Not : Not particularly. If your dentist carefully removes the bridge by sectioning it into pieces and gently removing it as to not traumatize the abutments, there is no reason for the nerve in that tooth to die, resulting in an infection and abscess. If the abutment already had root canal therapy, then don't give it a second thought. Hope this info helps.

Agree : Agree with dr. Davantzis. What you may be referring to is that each time a tooth has to be cut, for removal of decay or refining a crown preparation, the greater the risk that the nerve can be disturbed potentially leading to the death of the nerve. If the crown is removed atraumatically the tooth is not at greater risk for developing a nerve problems provided the tooth is protected by a well made temporary restoration while you are awaiting the permanent bridge.

It : It is true that the more work that is done on a tooth, the better the chance is that the pulp (nerve) may die. You may not necessarily develop an abscess, but you may need endodontics (root canal) to save the tooth.

Depends.: It depends on whether the supporting teeth have nay decay issues and how lon gathered last bridge was in place. Each time a tooth is drilled on it is controlled trauma. Therefore there is a chance of a root canal which is what you view as an abscess. Ignoring the issues with your current bridge will result in the same problems. Seek a second opinion to make you more comfortable with your decision.

Same dentist?: Each time a bridge is remade more tooth substance may be lost. Look for a specialist in crowns and bridges this time. That's a prosthodontist.

Maybe: It stands to reason that the cumulative dental history of a tooth results in more often and more complicated procedures.

Not necesarry: Depend on how much tooth structure remains. Of couse the more you prep the tooth the better the chances of needing root canal treatment.

A Chance: Every time a dentist drills a tooth the nerve gets aggravated to some degree. While it is not likely that the nerve may die, it is not likely.

Yes: The more you work on a tooth, the more trauma is delivered to it, increasing the chances for tooth nerve problems.Irreversible pulpitis (nerve inflammation) can happen leading to nerve death. This will eventually lead to a dental abscess. This should not discourage you, it does not always happens.

Possibly: Every time a vital tooth is cut on, there is an increase in risk of the nerve becoming inflamed to the point where a root canal is necessary.
