Sun Life Dental Phone Number: The 2026 Contact Directory for Members, Dentists, Claims & DentaQuest

Dental Practice Growth| Dental Practice Growth – Insurance Directories
October 11, 2026•12 min read

There is no single Sun Life dental phone number, because Sun Life runs dental through two separate operations. Sun Life U.S. handles commercial group dental sold through employers (PPO and prepaid plans), while DentaQuest, a Sun Life company since 2022, administers government dental such as Medicaid, CHIP, Medicare Advantage, and marketplace plans. Each side has its own numbers, websites, and logins. This directory pulls every verified Sun Life dental contact into one place, organized by who you are and what you need, so a front desk, a billing coordinator, or a patient can reach the right line fast. Every number and link below was taken from an official Sun Life or DentaQuest source.

Key Takeaways

  • Two operations, not one. Sun Life U.S. commercial group dental and DentaQuest government dental have different numbers, sites, and logins, so match the plan first.
  • 800-442-7742 is the Sun Life commercial dental Client Services line for PPO plans; 800-443-2995 is for prepaid and DHMO plans.
  • Dentists call Provider Relations at 800-434-2638 to join a network, for credentialing, or for fee-profile questions.
  • Commercial claims use payer ID 70408, and paper claims mail to Sun Life, PO Box 311, Milwaukee WI 53201-0311 (Florida group #A896 and New York have their own boxes).
  • DentaQuest member services is 888-278-7310 and provider services is 800-294-9650 for government and public plans.
  • Always start with the member ID card: both sides route many plans through group- or state-specific numbers printed there.

What's in This Directory

The Sun Life Dental Split: Commercial vs DentaQuest

The first thing to know is which Sun Life you are dealing with. "Sun Life dental" covers two different businesses under one parent, and calling the wrong one means a transfer at best and a dead end at worst.

  • Sun Life U.S. commercial group dental. This is the dental coverage sold to employers as a workplace benefit, in PPO form (the Sun Life Dental Network and Sun Life Focus Network) and prepaid or DHMO form. It is administered by Sun Life and its affiliate Dental Health Alliance, L.L.C. (DHA). Member and provider contacts live at sunlife.com/us.
  • DentaQuest government dental. DentaQuest, which Sun Life acquired in 2022, administers public and government dental programs: state Medicaid, CHIP, Medicare Advantage, and Affordable Care Act marketplace plans. It keeps its own brand, phone numbers, websites, and portals at dentaquest.com.

Which Sun Life Dental Is Yours?

The fastest way to reach the right office is to identify the plan type before you dial. Three steps get you there every time.

  1. Read the ID card. A card branded Sun Life for an employer plan points to Sun Life U.S. commercial dental. A card branded DentaQuest, or tied to a Medicaid, CHIP, Medicare Advantage, or marketplace plan, points to DentaQuest. The card almost always prints the exact customer service number to call.
  2. Match the number to the operation. Commercial dental lines are in the Sun Life U.S. tables below; government dental lines are in the DentaQuest table. The two do not share a call center.
  3. Pick the right line. Members call customer service; dental offices use a separate Provider Relations line and a provider portal. Use the department and login sections further down.

The myth of the "one Sun Life dental number"

Thin contact pages often publish a single 800 number and call it "the Sun Life dental customer service line." That is misleading. A Sun Life U.S. commercial PPO line cannot look up a DentaQuest Medicaid plan, and within commercial dental many employer groups route to their own number printed on the ID card. Chasing one universal number wastes time on hold and still ends in a transfer. Match the operation and the plan first, every time.

By Department: Claims, Enrollment & Credentialing

Sun Life U.S. commercial dental routes most eligibility and claim questions through the Client Services lines above, but claims submission, credentialing, and disputes have their own channels worth saving.

Claims: the quick rule

For Sun Life U.S. commercial dental, submit electronically with payer ID 70408 and your usual fees (not the network fee), include the tax ID, and confirm eligibility first through Client Services or the provider portal. Mail paper ADA claim forms to the member's matching PO Box above. DentaQuest government plans use separate addresses and payer IDs printed on the member's ID card, never the commercial addresses here.

Websites & Member / Provider Logins

Both Sun Life operations run everything through their own portals. Start from the correct brand, since a Sun Life login will not open a DentaQuest account and vice versa.

DentaQuest Government Dental Numbers

If the plan is Medicaid, CHIP, Medicare Advantage, or a marketplace plan, it is administered by DentaQuest. These are the national DentaQuest lines; because DentaQuest runs dozens of state programs, the number on the member ID card is usually the most direct, and the right state plan can be selected at dentaquest.com.

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 Sun Life or DentaQuest 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. Flawless charting and clean compliance are what stand between a routine audit and a costly dispute.

Frequently Asked Questions

What is the Sun Life dental customer service phone number?

For Sun Life U.S. commercial (employer) dental, the dental Client Services line for PPO plans is 800-442-7742 (7 a.m. to 5:30 p.m. CT), and prepaid or DHMO questions go to 800-443-2995. Because these plans are sold through employers, the fastest route is the number printed on the member ID card, and the general Sun Life line is 1-800-786-5433. If the plan is Medicaid, CHIP, Medicare Advantage, or marketplace, it is administered by DentaQuest, a Sun Life company, and member services is 888-278-7310.

Why does Sun Life dental have more than one phone number?

Sun Life runs dental through two separate operations. Sun Life U.S. handles commercial group dental sold through employers (PPO and prepaid or DHMO plans), while DentaQuest, acquired by Sun Life in 2022, administers government programs such as Medicaid, CHIP, Medicare Advantage, and marketplace plans. Each has its own numbers, websites, and logins, and within each, numbers are often tied to the employer group or state plan, so the ID card is the most reliable source.

What is the Sun Life dental provider phone number for dentists?

For Sun Life U.S. commercial dental, call Provider Relations at 800-434-2638 (7 a.m. to 4:30 p.m. CT) to join a network, for credentialing, or for fee-profile questions, and call dental Client Services at 800-442-7742 for PPO benefits, eligibility, and claim status, or 800-443-2995 for prepaid or DHMO plans. For DentaQuest government dental, provider services and utilization management is 800-294-9650. State-specific lines may apply, so confirm against the patient's ID card.

Where do Sun Life dental claims get mailed?

For Sun Life U.S. commercial dental, mail paper ADA claim forms to Sun Life, PO Box 311, Milwaukee WI 53201-0311 for all members except State of Florida members on group #A896 (PO Box 1618, Milwaukee WI 53201-1618) and New York members (PO Box 1428, Milwaukee WI 53201-1428). Most offices submit electronically using payer ID 70408. DentaQuest government plans use a separate claims address that varies by state plan and is listed on the member's ID card.

What is the Sun Life dental electronic payer ID?

For Sun Life U.S. commercial dental, the electronic payer ID is 70408. Offices can submit claims and attachments through VYNE/NEA, VYNE/Tesia, or DentalXChange, or through the Sun Life provider portal. DentaQuest government plans use their own payer IDs that vary by state program.

How do dentists log in to Sun Life dental?

For Sun Life U.S. commercial dental, the provider portal is at sunlife.com/providers (the common sign-in is login.sunlifeconnect.com), where offices check eligibility, submit claims, and view explanations of benefits. For DentaQuest government dental, the provider portal is providers.dentaquest.com. Offices that work both sides need an account on each portal.

How do Sun Life dental members log in or get an ID card?

Sun Life U.S. commercial dental members sign in or create an account at login.sunlifeconnect.com to view benefits, track a claim, and get a digital dental ID card, and there is a Sun Life Dental (U.S.) mobile app. A claim can be submitted as a guest at member2.sunlifeconnect.com. DentaQuest government dental members use the member portal at member.dentaquest.com.

Is DentaQuest the same as Sun Life dental?

DentaQuest is a Sun Life company. Sun Life acquired DentaQuest in 2022, and it administers government and public dental benefits (Medicaid, CHIP, Medicare Advantage, and marketplace plans) under the DentaQuest name. Sun Life U.S. commercial group dental and DentaQuest government dental are run as separate operations with their own phone numbers, websites, and logins, so a Sun Life commercial number will not pull up a DentaQuest Medicaid plan and vice versa.

How do dental offices join the Sun Life dental network?

Sun Life's PPO networks are the Sun Life Dental Network and the Sun Life Focus Network, which include dentists contracted with Dental Health Alliance, L.L.C. (DHA). To join, call Provider Relations at 800-434-2638 or email [email protected] for PPO, or [email protected] for prepaid plans. There is no fee to join, and all dentists are credentialed to NCQA standards before being accepted.

What is the DentaQuest member services phone number?

DentaQuest general member services is 888-278-7310, Dental Care Plus Group member services is 800-367-9466, and the hearing-impaired line is 800-466-7566. Because DentaQuest administers state Medicaid, CHIP, Medicare Advantage, and marketplace plans, numbers are often specific to the state plan, so call the number on the member ID card or select your state at dentaquest.com.

How do I file a Sun Life dental grievance or dispute?

For Sun Life U.S. commercial dental, provider payment or administrative disputes go to Sun Life / Grievance Department, PO Box 419596, Kansas City, MO 64179-0155, by fax at 563-242-0184, or by email at [email protected]. Members should start with the dental Client Services line on their ID card before escalating.
