Invisalign makes my teeth hurt
Mild pressure or tenderness can follow a new aligner, but sharp pain, swelling, or a damaged tray needs dental review.
The short answer
Mild pressure or tenderness can follow a new aligner, but sharp pain, swelling, or a damaged tray needs dental review. The discomfort should be checked if it prevents eating, remains severe, or does not improve as the tray change progresses.
What causes tenderness when an aligner moves teeth?
An aligner applies controlled force through its plastic shell to the crowns and roots of teeth through the periodontal ligament. Tenderness can occur when a new tray changes that force, while pain in one tooth can also reflect a sharp edge, poor fit, decay, gum inflammation, or another problem.
What can you check when a new aligner hurts?
Check the tray for cracks, distortion, or a rough edge and use the prescribed seating aid if your orthodontic team supplied one. Follow the treatment schedule, choose softer foods for a short period, and use only pain medicine that is appropriate for your health and prescribed instructions; do not cut, heat, or force the aligner.
When does Invisalign tooth pain need dental review?
Contact the treating orthodontist if pain is sharp, concentrated in one tooth, worsening, or associated with a loose attachment, broken tray, gum injury, swelling, or a change in your bite. Facial swelling, fever, or trouble swallowing requires prompt assessment rather than waiting for the next scheduled tray.
What should you ask about painful teeth during aligner treatment?
Ask whether the tray fits correctly, whether an attachment or tooth needs checking, and whether you should continue, pause, or move back to a previous tray. Ask how to manage the specific pain and whether decay, gum disease, or a bite problem could be contributing.
Frequently asked questions
Should I stop wearing the aligner?
Do not make a prolonged change without guidance from the treating orthodontist, but contact the team promptly if the tray causes significant or sharp pain.
Why does one tooth hurt more than the others?
A single tooth may be receiving concentrated force, or it may have a fitting, attachment, decay, gum, or nerve problem that needs examination.
