Overview

We keep Listerine Advanced Defence Gum Treatment Mouthwash (500ml), Clinically on our dental care shelf alongside 49 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Listerine is the #1 mouthwash brand in the UK*, Listerine Advanced Defence Gum Treatment Mouthwash is clinically proven to treat gum disease and prevent it from recurring. Bleeding gums can be a sign of gingivitis, an inflammation of the gums caused by plaque bacteria sticking to your gums. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.6 out of 5 from 7,800 ratings. We work out below what that is worth against everything else on the shelf.

How it compares on the dental care shelf

We track 50 rated dental care products, and the middle of that pack scores 4.6 out of 5. This one is on 4.6. That sits mid-table. Ratings this close together don't decide anything on their own, so weigh pack size, price per unit and the specifics below instead.

7,800 people rated it, where the shelf median is 5,287. Enough reviews to trust the direction, not enough to close the question.

The shelf runs from £1.18 to £56.00 and the midpoint is about £4.48. On price, this one is in the middle third. Which is where most sensible buys end up: not the cheapest on the shelf, and not the one you pay a name for.
