How bad does invisalign hurt
Clear aligners commonly cause pressure and tenderness when a new tray moves teeth, but sharp or persistent pain is not expected.
The short answer
An aligner applies controlled force through the periodontal ligament, the tissue between each tooth root and its socket. Tenderness is often most noticeable after changing trays, while rubbing usually comes from an edge or attachment.

How should you manage tenderness or rubbing while wearing it?
Wear the aligner as prescribed, use orthodontic wax over a rubbing edge, and choose softer foods if chewing is tender. Keep the trays clean and do not force an ill-fitting tray into place.
Which aligner symptoms mean you should contact the team?
Contact the orthodontic team for sharp pain, a loose attachment, a cracked tray, a tray that cannot seat, facial swelling, or pain that does not settle. Urgent care is needed for trauma or breathing and swallowing difficulty.
When should aligner pain receive dental or urgent review?
Ask whether the fit is correct, which tooth is causing the pain, whether an attachment needs repair, and whether the next tray should be delayed.
