Does Aetna have a missing tooth clause?
Aetna calls it the Tooth Missing But Not Replaced Rule — a positive requirement that the tooth came out while the policy was in force, plus a 5 or 8 year abutment condition.
Aetna carries the rule on most plans but does not call it a missing tooth clause. Its name is the "Tooth Missing But Not Replaced Rule", and it is written as a positive requirement rather than an exclusion: the first installation of a removable denture (D5110/D5120), fixed bridgework (D6240, D6740–D6752), partial (D5211/D5213) or other prosthetic service is covered only if it replaces a natural tooth that was removed while the policy was in force. It carries a second condition most offices miss — the appliance must not be an abutment to a prosthesis installed in the prior 5 years under the DMO plan or the prior 8 years under the PPO plan. And it is switched off for California and Texas residents on the DMO plan. Kaylie has not measured how many Aetna plans carry it, so no share is published here.
What Aetna's own policy says
The rule, in the carrier's own words: "Tooth Missing But Not Replaced Rule … Coverage for the first installation of removable dentures; fixed bridgework and other prosthetic services is subject to the requirements that such … are (i) needed to replace one or more natural teeth that were removed while this policy was in force for the covered person". (Aetna California DMO Voluntary Option 4A benefit summary.)
The second condition, from the same summary: the appliance must "(ii) … not [be] abutments to a partial denture; removable bridge; or fixed bridge installed during the prior 5 years under the Dental DMO plan and 8 years under the Dental PPO plan."
The state exemption is written into the rule's own heading: "(This item does not apply to California or Texas residents under the DMO plan)". Aetna states the same carve-out at carrier level for the DMO: the pre-existing services exclusion and the Tooth Missing But Not Replaced rule do not apply to Texas DMO members.
Aetna's federal plan kept its version into 2026, and it measures the look-back differently: "Not covered: Partial or full removable denture, fixed bridgework or other covered prosthetic services (including implant abutments/crowns) if it includes replacement of one or more natural teeth missing prior to you being covered under a participating FEDVIP plan or the prior TRDP plan." (Aetna Dental FEDVIP 2026 Brochure, Office of Personnel Management; the same wording is in the 2025 brochure.) FEDVIP is the Federal Employees Dental and Vision Insurance Program and TRDP was the TRICARE Retiree Dental Program that preceded it. The clock therefore runs from the enrollee's first coverage under any participating federal dental plan, not from the day they joined Aetna. The brochure then gives the carve-out: the exclusion "does not apply if it also includes replacement of a natural tooth that is removed while you are covered and was not an abutment to a prosthetic appliance installed during the prior five years".
Note that Aetna kept its federal missing tooth exclusion in 2026 while Delta Dental removed its own from the same program in 2025 — two carriers, one federal program, opposite answers.
Why it depends on the plan
The employer group's contract decides whether the rule is in the plan at all, and a state regulator can switch it off for a product. Across 4,990 employer groups in Kaylie's verified answers in August 2026, all plans within one group gave the same missing-tooth answer 97.9% of the time, against 84.2% for the carrier name alone. On Aetna specifically there are three variables, not one: whether the rule is in the plan, whether the member is a California or Texas DMO member, and whether the appliance trips the 5 or 8 year abutment condition.
What to do
Ask for the rule by Aetna's own name — "Does this plan have the Tooth Missing But Not Replaced rule?" — because asking for a "missing tooth clause" can get a no from someone reading a benefit summary that never uses that phrase. Then ask whether the member is on a DMO or a PPO product and in which state, and record it.
Collect the two dates the rule turns on before quoting: when each tooth in the span was removed, and the patient's coverage effective date. On a federal plan, ask instead when the patient first had any FEDVIP dental coverage or TRICARE retiree dental coverage — an earlier date than the Aetna start date usually helps the patient.
Check the abutment condition separately. If the new appliance would serve as an abutment to a bridge or partial placed within the last 5 years on a DMO or 8 years on a PPO, it can fail this rule even when the tooth came out while covered. Write the answer, the product type and the state into the plan record.
