That's one of those "How high is up" kinds of questions. If a cow is in good condition without excesive supplements it doesn't much matter if she's young or old. And young and old are pretty subjective terms. I'm young at 60 plus, I was old at 50. As has been pointed out, a broken mouth cow has a harder time staying in condition, especially if she's feeding a calf. Now the catch. If the forage is lush the ld girl may fool you and stay in condition for several years even while feeding a calf. Gritty forage wears teeth much faster then then gritty forage. But it won't cause them to loose teeth. If a cow is 6-7 and has lost teeth I would look first to genetics. In the desert where the forage is wirey cheatgrass liberaly dosed with sand, it's not all that uncommon for a 3 yr old to be a short and solid. She may not go broken mouth for another 5-6-7 who knows how many years. But the badely worn teeth are as bad, or almost anyway, as broken mouth. More then you wanted I know
