Unum Dental Phone Number: The 2026 Contact Directory for Members, Dentists, Claims & Logins
The Unum Dental phone number most members need is 888-400-9304, the customer service line for the Unum Dental PPO plan. But Unum runs dental benefits through more than one plan and brand, so the right number depends on what you hold: the PPO, the Unum Dental HMO, or a Colonial Life dental policy, and whether you are a member calling about benefits or a dental office calling about claims. This directory pulls every verified Unum Dental contact into one place, organized by role and by department, so a front desk, a billing coordinator, or a patient can reach the correct line in seconds. Every number and link below was taken from an official Unum or Colonial Life source.
Key Takeaways
- 888-400-9304 is the Unum Dental PPO customer service line for members, and the same number reaches the Group Dental Claim Office.
- Dentists use a different line. The Unum Dental PPO provider line is 855-400-9330, with eligibility and claims handled through the AlwaysAssist provider portal.
- The Unum Dental HMO is a separate plan with its own number, 800-937-3400, its own portal (unumdentalhmo.com), and its own claims address.
- Claims route to Baton Rouge. PPO claims go to P.O. Box 80139, Baton Rouge, LA 70898-0139, by mail, fax (855-400-9307), or email ([email protected]).
- Unum Dental is underwritten by Starmount Life Insurance Company, a Unum Group company, and administered on the AlwaysAssist platform.
- Colonial Life dental, a Unum sister brand, shares the same dental contact center and claims office, with its own claim email ([email protected]).
What's in This Directory
National & General Unum Dental Numbers
Unlike a federation of state companies, Unum Dental is a single national program, so there is one main member line per plan rather than one per state. The line most people want is the Unum Dental PPO customer service number, 888-400-9304, which also reaches the Group Dental Claim Office. The Unum Dental HMO is administered separately on its own number, and Unum's all-products support line is a useful fallback if you are not sure which benefit you are calling about.

Not Sure Which Unum Dental Plan Is Yours?
Because Unum delivers dental through more than one plan and brand, the fastest way to reach the right office is to identify the plan first, then pick the line for your role. Three steps get you there every time.
- Read the ID card. It names the plan and brand: Unum Dental PPO, Unum Dental HMO, or Colonial Life dental. The PPO card points to AlwaysAssist and unumdentalcare.com; the HMO card points to unumdentalhmo.com.
- Match the plan to its number. PPO members call 888-400-9304; HMO members call 800-937-3400; Colonial Life dental members call 888-400-9304. If the card is not handy, Unum's general line 866-679-3054 can route you.
- Pick the right line for your role. Members call customer service; dental offices use the provider line (855-400-9330 for the PPO, 800-937-3400 for the HMO) and a provider portal. Use the member and provider tables below.
The myth of the "one Unum Dental number"
It is tempting to treat 888-400-9304 as the number for everything Unum Dental. It is the right line for PPO members and PPO claims, but it will not pull up a Unum Dental HMO plan, and a dentist calling it for eligibility will usually be redirected to the provider line or the AlwaysAssist portal. Confirm the plan and your role before you dial, and you avoid the transfer.

Member Customer Service & Logins
Members call customer service for benefits, claim status, ID cards, and help finding a dentist. The line and the login depend on the plan. Numbers and sites below come from Unum's own dental pages and the plan sites.
| Plan | Member Customer Service | Member Login / Portal |
|---|---|---|
| Unum Dental PPO | 888-400-9304 | unumdentalcare.com / alwaysassist.com / unummwp.skygenusasystems.com (EOBs) |

Find an in-network Unum dentist
Unum's national dental network includes more than 323,000 access points. Members can confirm whether a dentist is in network at alwaysassist.com or through the Unum provider search tool, or by calling customer service at 888-400-9304.

Dentist & Provider Lines and Logins
Dental offices rarely use the member line. Unum publishes a dedicated provider number for eligibility, claims, and network questions, and routes dentists to a provider portal. For the PPO, the provider line is 855-400-9330 and the portal is AlwaysAssist for Providers (or the SKYGEN provider portal); for the HMO, Provider Relations handles eligibility, authorizations, and claims. The table below lists the verified provider contact and login for each plan.
| Plan | Dentist / Provider Phone | Provider Login |
|---|---|---|
| Unum Dental PPO | 855-400-9330; email [email protected] | unumdentalpwp.skygenusasystems.com / AlwaysAssist for Providers |
| Unum Dental HMO (DHMO) | 800-937-3400 (Provider Relations) | unumdentalpwp.skygenusasystems.com (Registration: /Registration) |
| Join the Unum PPO network | Submit the provider form; the Provider Team follows up | acpt.unum.com/dental-providers |
| Group administrators | via employer / broker | unummap.skygenusasystems.com |

By Department: Claims, Enrollment & Credentialing
Unum routes most dental questions through the main customer service line and the AlwaysAssist platform rather than a long list of department numbers. The lines below are the ones worth saving for claims, enrollment, and credentialing. For anything not listed, use the customer service number for the plan and the claims office address on the ID card.
| Plan | Claims | Enrollment / Group | Credentialing / Provider Relations |
|---|---|---|---|
| Unum Dental PPO | P.O. Box 80139, Baton Rouge, LA 70898-0139; fax 855-400-9307; [email protected]; status 888-400-9304 | via employer / broker (alwaysagent.com); general 866-679-3054 | 855-400-9330; join at acpt.unum.com/dental-providers |
| Unum Dental HMO (DHMO) | P.O. Box 318240, Baton Rouge, LA 70831; 800-937-3400; [email protected] | via employer / broker | 800-937-3400 (Provider Relations) |
Claims: the quick rule
Unum Dental has no central dental claims phone menu. Submit electronically through AlwaysAssist whenever possible for faster processing. For the PPO, mail paper claims on form CL-1190 to P.O. Box 80139, Baton Rouge, LA 70898-0139, or fax to 855-400-9307, or email [email protected], and call 888-400-9304 for status. For the HMO, claims route to P.O. Box 318240, Baton Rouge, LA 70831. Out-of-network reimbursements may ask for a pre-treatment estimate on claims over $300.

Colonial Life Dental: The Sister Brand
Colonial Life is a Unum Group company, and its voluntary dental plans run on the same dental administration as Unum Dental. If a patient's card says Colonial Life dental, the contact center, claims office, fax, and platform are the same, with a Colonial Life claim email. One exception: Colonial Life Fee Schedule dental plans are serviced by a separate administrator.

Where Documentation Fits In
For a sedation or oral surgery practice, every one of these calls (eligibility, claims, appeals) rides on documentation. Insurers deny or claw back payment when records are incomplete, and a Unum Dental claim for a sedation case is only as strong as the chart behind it. That is the gap iSedate's SedationVault was built to close.
SedationVault replaces paper sedation records with real-time oral and IV sedation charting, live vitals streamed from any monitor on the market, digital intake and consent, and one-click, audit-ready PDF reports. When a payer or a board asks for the record, the documentation is complete, time-stamped, and defensible, which protects both reimbursement and the practice itself. Clean charting and clear compliance are what stand between a routine audit and a costly dispute.
