Teeth that are crowded or too widely spaced can create unhealthy conditions, including swollen gums, redness and pocketing, all of which are signs of periodontal disease. As Invisalign invisibly straightens your teeth, it can also do great things for the health of your mouth.
Clinical studies have shown that gum health may improve with the use of Invisalign during orthodontic treatment¹. Properly aligned teeth can help gums "fit" tighter around each tooth², which may lead to better periodontal health. Unlike braces, with Invisalign, you can brush and floss normally, which can help prevent tooth decay and periodontal disease.
Unlike traditional orthodontics or braces, Invisalign has no metal bands or wires to trap food and plaque. Maintaining a good oral hygiene program will also reduce chances of plaque buildup, tooth decay and periodontal disease.
For some people, incorrectly positioned teeth and jaws can exacerbate speech difficulties and chewing problems. Correcting your bite by straightening your teeth can help improve both.
Properly aligned teeth can be less stressful on supporting bone and jaw joints.
