In 2023, I had a three-unit bridge placed on my front teeth to replace my missing right front tooth. The lateral incisor previously had a root canal and didn’t have much form left, so my dentist used a post to help support the bridge. Recently, the lateral incisor broke off at the gumline, right through the post. Now the bridge is supported by one tooth, which worries me.
I’m hoping there is a way to save the lateral incisor and have another post placed. What type of dentist could handle something like this? Will I need a specialist? – Thanks. Bram
Bram,
You’re dealing with multiple technical challenges. A post that breaks at the gumline leaves nothing for the dentist to grasp, which restricts removal methods. Although ultrasonic vibration can sometimes loosen a post, your situation would likely require drilling away additional tooth structure to reach it.
Because this involves the small lateral incisor (#7), removing more tooth structure would weaken the foundation for any replacement post. That makes long-term success less predictable.
Why the Bridge Would Need Replacement
A dentist would need to separate the crown from the bridge to access the post. Once that occurs, replacing the full bridge generally becomes unavoidable. This highlights a known limitation of a dental bridge: failure of one component often affects the entire restoration. Treatment planning shifts from repair to replacement.
How to Choose a Predictable Long-Term Solution
Placing another post does not guarantee better longevity and may shorten the repair’s lifespan. Strong sideways biting pressure on front teeth frequently leads to repeated fractures, which appears consistent with your experience.
Dental implant bridge
When weighing realistic solutions, dentists typically consider two options:
- Replacing the missing tooth and tooth #7 with two implants for independent support.
- Extending to a four-unit bridge from the canine to the opposite central incisor.
A longer bridge increases stress on the supporting teeth, which may be risky when breakage has already occurred. Only an in-person exam can confirm the best plan, but implants often provide greater stability in situations like yours.
