What they said

in their own words

Claude Opus 5 · picked Sensodyne

“I'd pick it because it combines fluoride for cavity protection with a lower-abrasivity formula that's gentle on enamel and sensitive teeth — a safe default for most adult mouths.”

Llama 4 Maverick · picked Crest

“I would choose Crest because it's a well-established brand known for its effectiveness in preventing cavities and strengthening tooth enamel, making it a reliable choice for maintaining good oral health.”

Gemini 3.1 Pro · picked Sensodyne

“I would choose Sensodyne because preventing sensitivity seems like the most practical way to protect the delicate "hardware" of human teeth.”

Grok 4.6 · picked Colgate

“It’s a widely available, fluoride-containing brand that most dentists recommend for everyday cavity protection, so it would be the straightforward, no-fuss choice for a typical evening brushing.”
