NAD Recommends Oral Essentials Discontinue Claim for Lumineux Whitening Strips

Following a reopened inquiry, BBB National Programs’ National Advertising Division recommended that Oral Essentials, Inc. (OEI) discontinue its “30 minutes to whiter teeth” claim for Lumineux Whitening Strips.

The case was reported in Happi last year, as seen here.

In the underlying challenge brought by the Procter & Gamble Company (P&G) (Case #7235), the National Advertising Division (NAD) determined that OEI provided a reasonable basis for its on-pack claim that Lumineux Whitening Strips “whitens without the sensitivity,” but recommended that OEI discontinue the claim “30 minutes to whiter teeth” or modify it to avoid conveying the message that consumers will experience whiter teeth after using the Lumineux product once for 30 minutes.

OEI discontinued the “30 minutes to whiter teeth” claim. In December 2025, OEI petitioned to reopen the proceeding and provided three new studies to support its claim. NAD determined that two of the studies were fatally flawed because they did not include a negative control, making it impossible for NAD to determine whether the whitening could be attributed to the Lumineux product or another variable.

Although the third study was randomized, double-blinded, and placebo-controlled, NAD determined that data discrepancies called its reliability into question. NAD found that the study included tooth color measurements that should have been “impossible and unusually high standard deviations.”

NAD therefore concluded that the PWS Study was also “fatally flawed.”

Accordingly, NAD recommended that Oral Essentials continue to discontinue the claim “30 minutes to whiter teeth.”

In its advertiser statement, Oral Essentials stated that its advertising “will comply with NAD’s recommendations.”
