Initial claims
No public number
Sun Life publishes claims addresses and a dispute channel but no filing windows. Its provider FAQ sends PPO dentists to The Dentist Guide at Dental Health Alliance (DHA, “a member of the Sun Life group of companies”), which is gated behind the DHA dentist login.

No Sun Life filing window is published, so there is no preset for it — enter the number from your participation contract.
Date of service plus the payer's filing window, in calendar days. Estimate only — the payer's contract wording controls.
Enter a date of service to compute the deadline.
Deadline = date of service + the filing window in calendar days; days left counts from your device's date today. This tool counts calendar days. Payer contracts may count differently — some windows run in months, from the end of the month of service, or from the date the payer received the claim — so treat the result as a planning estimate and confirm the payer's own contract wording. Windows outside 30–730 days are clamped, and a date of service more than a year ahead is rejected as a likely typo. Payer windows in the list carry the payer's published figure; the cited source appears on that payer's page.
Nothing you type here leaves your browser — the results are computed locally on this page.
