Dentist Questions Dental Bridges

How long does a dental bridge last?

If I decide to get a dental bridge, would I have to replace it very soon? I don't have it yet, but my dentist asked me to consider it.

The sooner you can replace a missing tooth the better for your bite function and health of the teeth.
Generally speaking, an anterior bridge lasts longer than a posterior because the biting forces on it are less strong. But the biggest determinant is how strong the supporting teeth are that support the bridge. If the support teeth do not have a lot of filling material and have not had root canal treatment, they are stronger and will last longer. On strong supporting teeth and a bridge that is only replacing one missing tooth, I would expect a lifespan of about ten years.
