I started orthodontic treatment in my mid-20s, but because I started late, my gums became weaker than before and I had chronic periodontitis, especially the nasolabial folds... Even before orthodontic treatment, I wasnt in the mood to look at it that way. It was a pity, 5 years after orthodontic treatment was completed, and I still wear retainers. I wear retainers every day, but my teeth are apart. At the hospital, it is important not to open as much as possible, so I only tighten the retainers. or dont do it
