Bridges
How long does a dental bridge last?
Most bridges last around 5 to 15 years, longer with good care. Clean under the false tooth as well as around it — a floss threader helps — brush and floss daily, and keep your check-ups.
How long a bridge lasts
Most bridges give good service for roughly 5 to 15 years, and often longer when you look after them well. A bridge fills a gap using a false tooth — a pontic — held in place by the teeth or implants on either side, so its lifespan leans heavily on keeping those supports healthy.
That is why care matters so much: a bridge does not decay, but the natural teeth anchoring it certainly can, and that is what usually decides how long the whole thing lasts.
The trick to making it last
The knack is cleaning underneath the false tooth as well as around it — a floss threader or a little interdental brush makes that easy — plus your usual daily brush and floss. Plaque loves to gather in the spot you can't reach with a brush alone, right where the pontic meets the gum.
Go gently with very hard or chewy things, and keep your check-ups so we can watch both the bridge and the teeth quietly doing all the holding. Caught early, a small problem around a support tooth is far easier to sort than a failed bridge.
Common questions
How do I clean under a dental bridge?
Use a floss threader or an interdental brush to clean beneath the false tooth where a normal brush can't reach, alongside your usual daily brushing and flossing.
What makes a bridge fail early?
Usually decay or gum disease in the teeth anchoring it, often from plaque building up under the pontic. Good cleaning and regular check-ups are the best way to get the full lifespan.
