How long before lost tooth will start to cause premature ageing?

[SugarFiend]

A lost tooth can cause premature ageing and or changes to jawbone/facial structure.

Once a tooth is lost, how long before this premature ageing starts.

Besides implants, what other ways can this ageing be prevented?

You are going to age whether you have teeth or not. The loss of teeth does not lead to premature ageing. If you take out a lot of teeth all at once and don't replace immediately, then sure, it will cause some facial changes to appear earlier. But not one or two teeth. Prevention? maybe Botox, dermal fillers, end up looking like a Barbie doll!
