Teeth that were straight at twenty-five and are crowded at fifty-five are not a sign that your orthodontics failed. This happens to people who never had orthodontics at all.
Late lower crowding is close to universal
The lower front teeth drift together over decades in most people. It happens with or without previous treatment, with or without wisdom teeth, and it is one of the most consistent findings in long-term studies.
It is a normal ageing change rather than something that went wrong.
What makes it worse
Loss of a back tooth that was never replaced, allowing everything to drift. Gum disease reducing the support that holds teeth in position. Grinding, which flattens the guidance that keeps teeth apart during jaw movement.
Those are worth identifying, because they are treatable and the crowding will otherwise recur after correction.
Whether to do anything
If it is stable, cleanable and not causing wear, monitoring is a legitimate choice. Not everything needs correcting.
It becomes worth treating when crowding makes cleaning genuinely difficult, when it is producing wear on specific teeth, or when it precedes restorative work that would otherwise be compromised.
If you do treat it
Adult cases are frequently short. Six to ten months with aligners handles a lot of late lower crowding, and treatment is far less visible than it was when many patients last considered it.
Retention afterwards is indefinite, and that is not negotiable. Teeth that drifted once will drift again, and a bonded retainer is the reason people who had treatment at twenty still have straight teeth now.
Have it assessed rather than assumed. Some late crowding needs nothing, some is a symptom of something else, and the distinction is worth establishing.
