What is a missing tooth clause?

A plain-words definition with the carriers' own wording, how often plans carry it, and why the employer group predicts the answer better than the carrier does.

A missing tooth clause is a provision in a dental plan that refuses to pay for the first prosthesis replacing a tooth the patient had already lost on the day coverage started — the initial bridge (D6240, D6740–D6752), implant (D6010), removable partial (D5211/D5213) or complete denture (D5110/D5120). It is not about how the tooth was lost or whether the treatment is necessary; it is a date test, comparing the extraction date against the coverage effective date. As of September 2026, of 10,873 plan verifications Kaylie ran in a single week of July 2026, 1,611 (14.8%) said the clause applies. It was the stored denial reason on 87 of about 65,500 denied claim lines — 0.1% — a rare denial reason, and one that by definition falls on prosthetic cases.

Say the polarity out loud every time, because the two answers contain each other as a phrase. "The missing tooth clause applies" means the plan will not pay. "No missing tooth clause" means it will.

What we measured

The first row counts plan verifications — one patient's benefit check each, so a plan can appear more than once — where the plan answered either way, across all carriers. The second counts claim lines paid at zero with a reason recorded on the remittance, measured September 2026; for comparison, procedure not covered is 22.3% of denials, frequency limits 14.4% and age limits 9.1%. The third and fourth rows measure how well the group and the carrier each predict the answer. These are Kaylie's own verification and remittance data, aggregated so that no practice, employer or patient is identifiable — there is no published industry statistic for how many dental plans carry the clause.

What the carriers' own policies say

Delta's federal brochure names it and defines it in one heading: "Tooth Missing but Not Replaced Rule — The installation of complete or partial removable dentures, fixed partial dentures (bridges), implants and other prosthodontic services will be covered when replacing or repairing a pre-existing, failed prosthodontic appliance/device that was in existence prior to your coverage effective date… Initial prosthodontic services to replace natural teeth that were missing prior to your … date of coverage are not covered." (Delta Dental FEDVIP 2024 brochure, Section 4.)

Anthem gives the tightest statement of the trigger: "The missing tooth clause applies to teeth extracted and not replaced prior to plan coverage." (Anthem Dental Clinical Policy 06-701, Abutment Crowns and Fixed Partial Dentures.) The two conditions in that sentence — extracted, and not replaced — are what a reviewer checks.

Renaissance writes the strictest version, on its own public policy page, identically across every plan tier: "We will not make payment for (a) procedures to replace a missing tooth or teeth that were lost prior to the date that a Covered Person was covered under this Policy; or (b) the replacement of teeth beyond the normal complement of teeth; or (c) services associated with overdentures; or (d) posterior bridges in conjunction with partial dentures in the same arch." (Renaissance Dental Plan Exclusions and Limitations policy page.)

And here is the sentence that reaches the patient when it fires: "The replacement of a tooth extracted prior to the patient's effective date of coverage is not a covered benefit of the enrollee's program. Therefore, the patient is responsible for the amount indicated as 'Patient Pays.'" (Delta Dental policy ID mapping for CARC and RARC health care policy codes, policy 634.) The balance becomes patient responsibility rather than a contractual write-off.

Why it depends on the plan

The clause is bought or declined in the contract, and for most patients that means the employer decided it. That is what the group and carrier numbers above measure: knowing the employer group predicts the answer 97.9% of the time, knowing only the carrier 84.2% of the time. A carrier-level rule of thumb is wrong about one time in six.

The shape varies as much as the answer. Some Cigna DPPO plans reduce the benefit to 50% for 12 months rather than excluding it. Anthem's usual version is a 24-month or 12-month wait. One Delta federal program pays 30% for 24 months and 60% after. Blue Cross Blue Shield of Alabama's federal plan stops applying after 24 consecutive months. So "does the plan have a missing tooth clause" is only the first question; "for how long, and at what percentage" is the second.

What to do

Ask for the clause by name at verification, and record the answer against the employer group in the practice management system, not against the patient — the next patient from that group will nearly always have the same answer. Ask two follow-ups: does it expire, and does it lift if the appliance also replaces a tooth extracted after coverage began.

Then get the dental history the clause turns on before you quote: which tooth is being replaced, when it came out, and the patient's coverage effective date. Where the extraction predates coverage on a plan with the clause, quote the case as self-pay until the plan document says otherwise, and quote the pontic separately from the retainer crowns — several carriers review the crowns on their own merit and often allow them when the pontic is denied, though that review can still end in a denial.
