Is a dental bridge covered by insurance?
Usually yes, as a major service at around 50%, unless the tooth was lost before the plan started. The replacement tooth in a fixed bridge (code D6240, porcelain over a precious metal base) is the piece that floats over the gap, held up by crowns on the teeth on either side. Each piece of the bridge is billed as its own unit.
50%
Major, billed per bridge unit
3 units, 1 visit
A typical bridge is one replacement tooth plus two anchor crowns (D6750), each its own claim line at 50%. Half of three units usually clears the annual maximum.
Lost before = no
The missing tooth clause hits bridges hard. If the gap existed before the plan's effective date, the pontic can deny even when the anchor crowns pay.
Metal downgrade
Many plans pay the base-metal pontic fee (D6241) as an alternate benefit, no matter what the lab used. The difference is the patient's.
Estimate first
Bridges are the classic pre-treatment estimate case. The eligibility check gives you the major percentage, waiting period and remaining maximum before the estimate even goes out.

When D6240 is the right code
- A gap between two natural teeth being crowned
- The replacement tooth is fixed, not removable
- Porcelain outside, precious metal underneath
- Held by natural teeth, not by implants
Documentation payers expect
X-rays showing the gap and the anchor teeth, the date the tooth was lost, and a pre-treatment estimate. Most plans want each unit listed on its own claim line.
Why bridges get denied
What happens after the bridge
A bridge usually empties the annual maximum in one visit: three units at 50% is more than most plans allow for the year. Every other major claim on that patient, a crown (D2750) or a partial, moves to the next plan year. Then the bridge starts its own 5 to 10 year replacement clock, and a recent crown on one of the anchor teeth carries over as history. The desk that pulls the remaining maximum and the major percentage before the estimate can tell the patient what waits until January.
D6240, quick answers
Does insurance cover a dental bridge?
Most plans cover the pontic (D6240) and the anchor crowns as major work at around 50%, subject to the deductible, waiting period, annual maximum and missing tooth clause.
What is the missing tooth clause on a bridge?
If the tooth was lost before the plan's effective date, many plans will not pay to replace it, even though the anchor crowns may still be covered.
How is a bridge billed?
Unit by unit. A three-unit bridge is one D6240 pontic and two D6750 retainer crowns, each on its own line with its own tooth number.
Does a bridge need a pre-treatment estimate?
Most plans recommend it for major work and some require it. Send it once you know the major percentage and remaining maximum from the eligibility check.
How often will a plan replace a bridge?
Typically once every 5 to 10 years, and a crown placed recently on an anchor tooth can block the retainer for that tooth.
