How it compares on the dental care shelf

Across the 50 rated dental care products we track, the middle of the pack sits at 4.6 out of 5. This one scores 4.2. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.

4,572 people rated it, where the shelf median is 5,287. That's enough for the score to mean something without being the last word on it.

On money, this sits in the top third of a shelf running from £1.18 to £56.00, with the midpoint around £4.48. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.
