The eleven biggest names in oral care hold less than half of their own shelf.
Why these three lead the shelf
1. Colgatechosen 36× / 7.8% / 4/4 models
The only brand that is both everywhere and chosen. Named in twelve of the fifteen questions, and the first answer on whitening across all four models and on everyday care in three of them. Breadth is common here; breadth that converts is not.
2. Crestchosen 34× / 7.4% / 4/4 models
Almost exactly as visible as Colgate and almost never picked. Named in eleven of fifteen questions, but the first answer in only three of sixty. It is the reliable second name on whitening, sensitivity and enamel alike.
3. Sensodynechosen 24× / 5.2% / 4/4 models
The narrowest of the three and the most decisive. It appears in nine questions, not twelve, but owns sensitive teeth across every model and enamel in three. One job, claimed the same way for decades.
About the AI Shelf
The AI Shelf is the short list of names an AI assistant gives when someone asks what to buy. ChatGPT, Claude, Gemini and Perplexity answer the questions a real buyer asks, and every brand they name lands on the shelf. Your customer sees it before they see yours, and nobody can pay for position on it.
Each time a model chooses a brand over every other brand it could have named, that counts once. 462 choices were made here. Slice size is share of all of them.
41.6%held by the 11 audited brands

33.6%audited share of the newer buying questions
The takeaway
The household names still lead this shelf, but they no longer hold it. Ask the classic questions and the eleven audited brands hold roughly half the answers. Ask the newer ones a buyer actually asks now — kids, bad breath, what is worth paying more for, what belongs in your bathroom — and their share falls to a third. The ground the majors have not claimed is not empty. It is occupied by brands most of their executives could not name.

ARA / ALGORITHM READINESS ANALYSIS / ARACO.AI — 4 models x 15 shopper questions, every brand named per answer. MEASURING AI TRUST IN BRANDS. Naming variants merged before counting: Apagard / Aquafresh / BURST / Bite / Close-Up / Davids / Dr. Tung's / OJOOK / Pro-Sys / RiseWell / SURI / Selahatin / Waterpik. Query counts for merged brands are upper bounds. Movement (Δ) is measured on share of the eight questions carried word for word from Q2, in percentage points. Answers ran deeper this quarter (7.8 brands named per answer against 6.4) so raw counts do not compare, and this is the first oral care reading where every model searched the live web, which favours brands with recent third-party coverage. Share, not counts, and read the direction not the decimal — a different basis from the placement counts beside it, which cover every question in the quarter.
