long in the tooth
Unlike humans, guinea pigs don't lose their teeth, ( nor do they brush them) this allows to maintain healthy and strong teeth. eating hard foods and constant chewing help wear down the teeth to keep them at a proper and comfortable length. when a guinea pig breaks a tooth it is able to grow back allowing it to eat.
I don't think they stop growing per se, just that the act of gnawing helps wear down the teeth (i.e. shorten the teeth). They keep growing forever, though.
