D9975

Take-home teeth whitening (custom trays)

Code Summary

D9975 is the CDT code for external teeth whitening for home application, including the materials and custom-made trays. You whiten gradually at home using dentist-provided trays and gel. Like all whitening, it's cosmetic and not covered by insurance.

What D9975 means

D9975 covers external bleaching for home application, per arch, including the whitening materials and the fabrication of custom trays. "D" is dental, "99" is the adjunctive general services group, and "75" is take-home whitening. The dentist takes impressions or a scan to make trays that fit your teeth precisely, then provides professional whitening gel to use in them at home over a series of days.

The custom-tray approach is more gradual than in-office whitening but very controlled: the trays hold the gel evenly against the teeth and limit contact with the gums. Many people find it convenient and effective, and the trays can be reused for touch-ups later with new gel.

Its companion is D9972, in-office (chairside) whitening, which is faster but usually costs more. Both are cosmetic. The custom-tray system is also more effective than over-the-counter strips because the trays are made to fit and the gel is professional strength.

When it's typically used

D9975 is reported when the dentist provides custom whitening trays and professional gel for the patient to whiten their teeth gradually at home, for cosmetic lightening of tooth color.

How much does D9975 cost?

Take-home whitening with custom trays is a cosmetic fee, often roughly 200 to 500 USD depending on region and office, usually less than in-office whitening. Replacement gel for later touch-ups is typically an added cost.

Is D9975 covered by insurance?

Whitening is cosmetic and essentially never covered by dental insurance, so D9975 is an out-of-pocket expense. A dental office can quote the exact price, including the custom trays and gel, in advance.
