“Perio traps,” or microscopic gaps between teeth caused by loose contacts during orthodontic retention, can lead to food debris accumulation, bad breath, and potential periodontal disease [1]. Dr. Amanda of StraightSmile Solutions advises that if floss lacks a “snap” or produces an odor, these gaps must be addressed immediately to avoid severe gum tissue and bone loss [1]. Early intervention often involves fabricating new active retainers or using limited aligners to close the spaces [1].
