The post in my left front tooth broke. The tooth is part of a four-piece bridge, replacing the incisor and canine teeth behind it. I had a 2018 accident 2018 that knocked out some teeth and broke others. My dentist did a root canal on the front tooth to help support the bridge, but my latest x-ray shows the tooth and post broke at the gumline. My dentist said I had a heavy bite. She wants to redo the post and bridge, but I want to do dental implants or an implant bridge. Why keep repeating the procedures? What should I do now? Francisco
You are right. What will prevent a new post from breaking in a tooth so weak? You have several challenges that require the skill of a dentist with advanced training in occlusion, bite, and dental implants. We will discuss them.
Broken Tooth Post
Dentists are limited in the techniques they can use for a tooth post that breaks at the gumline. A dentist must drill away tooth structure to grab, twist, and remove the post. Removing tooth structure would further weaken the tooth, making it challenging to retain a new post. Although some dentists use an ultrasonic scaler to hold the post, it would not work for your case.
Broken Post in a Dental Bridge Tooth
When a post breaks in a tooth part of a dental bridge, a dentist must cut off the bridge to access the tooth. You would need a new bridge. Replacing missing teeth with dental implants is a long-lasting repair that does not affect neighboring teeth.
Heavy Biting Force
If you have a heavy bite that may have contributed to the broken tooth and post, it will likely occur again. We recommend getting an in-person second opinion and exam from an advanced dentist. You will probably need dental implants to replace your missing teeth and the tooth that broke at the gumline.
