Do invisalign hurt your gums
Clear aligners can irritate the gum edge when they do not fit, but persistent bleeding or swelling needs an examination.
The short answer
Invisalign aligners should not routinely injure your gums, although a rough edge, trapped plaque, or excessive pressure can irritate the gum margin.
What gum tissues can an aligner affect?
The gums are the soft tissues surrounding the necks of the teeth. A clear thermoplastic aligner rests over the teeth and can rub the gingival margin or hold plaque against it when its edge, fit, or cleaning is inadequate.
How can you protect irritated gums while wearing aligners?
Remove only the obvious sharp plastic with an aligner file supplied by the treating clinician, clean the tray and teeth, and wear the aligner as directed. Do not keep using a tray that rocks, cracks, or repeatedly cuts the gum; the orthodontist can inspect the fit and smooth or replace it.
When do sore or bleeding gums need dental care?
Arrange dental or orthodontic care if bleeding, a sore ulcer, swelling, bad taste, or pain persists after the tray is cleaned or removed. Seek urgent care for rapidly increasing facial swelling, fever, difficulty swallowing, or difficulty breathing.
What could be causing irritation beneath the aligner?
Ask whether the irritation comes from the aligner edge, tooth movement, plaque-related gingivitis, or an unrelated gum condition, and whether the tray needs adjustment, replacement, or a revised wear schedule.
Frequently asked questions
Can I put wax on the tray?
Orthodontic wax may temporarily cover a rubbing edge, but it does not correct a poor fit. Contact the treating clinic for an adjustment.
Should I stop wearing the aligner?
Remove it if it is cutting the gum, then contact the orthodontic team promptly for instructions and a fit check.
