I have a bridge with a cavity under one of the crowns. Dentist wants to do a root canal . I said how does that fix the cavity. He just wants to do the root canal. And not fix the cavity. Going for second opinion.
Drill out the cavity past the nerves and add wicks in place of the nerves then seal the hole and replace the crown.
I've had two root canals and both are the result of compromised fillings from many years ago. One was a molar and the orthodontist drilled through leaving it in place until after the procedure was complete. Most recommend the Cubic Zirconia because it's one piece and does not show past the gum line and are stronger. Rear out of sight replacement can be porcelain with a metal base. As we age the gums recede and show more of the tooth's base.
The 2nd tooth is a front one, so that is Zirconia, drilled, ground and crowned.
