As far as I've always understood it -
If they've got all of their baby teeth, they're no older than a certain age. If they're missing a few and have some adult teeth, they're a different age. If they've got all of their adult teeth and they look sparkling clean, they're usually still young (like under 2 years or so) and then usually use the amount of tarter or decay to judge older cats.
Of course it can be tough in cats who have really bad teeth or really good teeth regardless of age, but just a general guideline.
Size can also help, but cats can very greatly in size so its usually not a good way to judge.
