Crowded or tilted teeth are harder to clean. Wherever brush and floss cannot reach, plaque remains – and that is exactly what encourages inflammation of the periodontium.
So when the gums have already receded, the order matters: first we treat the periodontitis and settle the inflammation. Aligner treatment only starts once the gums are stable.
In this situation aligners have a practical advantage: they are removable. You keep brushing as usual, with no brackets or wires to clean around. With an already weakened periodontium, that is a noticeable difference.
We deliberately plan gentle forces. The aim is to move the teeth into a position where they are easier to care for and more evenly loaded.
Whether aligner treatment makes sense in your case can only be determined after an examination, which always includes an assessment of the periodontium.
