UpWhiten Editorial Policy: Every Study Checked on PubMed

Every whitening site carries numbers, and almost nobody says who checked them. One audit bought whitening gels online. Every listing, 100% of them, had an incomplete or missing ingredient list, and one delivered sample had no active ingredient at all.[2]

You can check every number here without taking our word for it. Each one has to appear in a PubMed abstract, and the phrase it came from is checked before the page goes live. One miss fails the page, and the author does not get a vote.

A box of whitening strips prints a promise on the front and never prints a reading. So it cannot tell you where you started, or when you are done. You buy another box every few months, for years, and nobody writes the number down.

Who writes each type of page

Wahid Baitul, co-founder of UpWhiten, is the author of record on every page here, and every page argues a case for the studio. He runs the sessions and keeps the records. No page publishes until he has signed off on every sentence.

Dr. Hafsa Cherid, DMD, reviews the health statements. She reads every sentence about enamel, sensitivity, gums or safety against the study it cites, and says when it claims more than the study found. UpWhiten is a studio, not a dental clinic, and her review does not make it one.

She works with the studio and is paid for the review. She cannot approve a page, only refuse a sentence.

Which pages have had clinical review

A page has had clinical review when a reviewer line sits under the byline, with her name and the date of the revision she read. No line means no review, and we would rather show no line than imply one.

Pages about safety, sensitivity, enamel or gums carry the line, and so does every page that says what whitening does inside a tooth. Pages about price, a neighbourhood, or this policy make no health statement, so they carry none.

A review is tied to one revision of one page. A changed health sentence goes back to her before the new wording publishes, and the printed date moves to that revision.

How evidence and conflicts are disclosed

Every study we cite is a real PubMed record. A script fetches that abstract before the page publishes and looks for one short phrase we copied out of it. A missing phrase fails the build, and the page does not go live.

Our teeth whitening page says whitening strips needed nearly thirty-two treatment cycles to reach six grades of whitening, and the chair arm needed just over three.[1] Both figures are printed the way the abstract prints them.

An UpWhiten figure comes from the studio’s own records, never from a trial, and carries its date the first time it appears. The median client goes from first visit to final reading in about five weeks, on the studio’s own records to 12 September 2026.

Buyer quotes are verbatim, first name and last initial, grammar untouched. The two kinds of number never share a sentence.

We sell whitening, and every page here argues for a visit to the studio. We print the findings that cut against us too. One trial read a chair course four and a half years later, and the colour had drifted back by just over two shade-guide units.[4]

One Cochrane review pooled seventy-one trials of take-home whitening, the dentist’s own trays included, and rated that evidence low to very low.[3] Nothing on the shelf has been shown better than anything else on it.

What an UpWhiten article will not print

No article here prints a star rating or a review count, and none will until a third party we do not pay has verified them. We do not print the strength of our own gel; the page says professional strength and stops.

No article here prints a shade number as a promise, because your teeth were never read when the promise was written. The NanoChroma™ scale runs thirty-eight steps, from S40, the most yellow, to S2, the whitest. Where you stop inside them is your genetic limit, not a number we picked for you.

We do not print a dentist’s price, because we did not set it. At a dental office the number arrives after a paid exam, per session or per tray, and it moves again every time you need more. The chair visit is the opener; the tray you take home, a fortnight of nights, is the real product.[7]

No article here prints a dollar figure, ours included. UpWhiten sells one Ideal Shade Package: unlimited sessions until you reach your ideal shade or your genetic limit, at no extra cost. You hear the one number at the free Complimentary Shade Consultation, after the reading.

We do not hide the method behind a vaguer word. Predictive Whitening™ is how UpWhiten whitens. NanoChroma™ reads your starting shade on an instrument, in the chair, before any gel is opened, and reads it again at the end.

At a dental office someone holds a plastic tab beside your tooth and decides by eye. One systematic review compared shade readings taken by instrument against readings taken by eye, and found the instrument significantly more accurate than visual matching.[5]

How readers request a correction

Ask through the contact details in the footer, and name the page and the sentence. A correction request goes to the author first and, when the sentence is a health statement, to Dr. Cherid as well.

We never delete a request, and one of three things happens. The sentence is right, and we reply with the record it rests on. The sentence is wrong, and we change it, and the page shows a new updated date.

Or the sentence says more than its study says, and we cut it back to what the abstract prints.

The same rule binds what we say about a rival. The 22% oral irritation we report in 148 strip users, pooled from seven trials, comes off a meta-analysis whose own conclusion calls the strips safe.[6]

Where this page stops

This page stops at how the pages are written and checked. The people who run the studio are on the about upwhiten page, and what clients say is on the upwhiten reviews page.

The health question, whether whitening is safe for your teeth, sits on its own page and carries the reviewer line. What happens at a session, and what the reading decides, sits on the Ottawa studio page.
