Pain from aligners
Aligners can cause pressure tenderness and rubbing while teeth move, but sharp or persistent pain may indicate a poor fit or another dental problem.
Is pain from aligners normal or a sign of a problem?
Aligners can cause pressure tenderness and rubbing while teeth move, but sharp or persistent pain may indicate a poor fit or another dental problem.
Why can moving teeth make them feel tender?
Pressure comes from the periodontal ligament and surrounding bone responding to tooth movement. A rough edge can irritate mucosa, and a loose filling, cavity, gum problem, or crack can cause pain unrelated to orthodontic movement.
How can you wear and care for painful aligners?
Wear the tray according to the orthodontic plan, use orthodontic wax over a rubbing edge, and keep the appliance clean. Do not cut, heat, or force the plastic, because altering its shape can change the intended force.
When should aligner pain or a poor fit be checked?
Contact the orthodontic team if pain is intense, lasts beyond the early adjustment period, a tooth becomes very sensitive, or the tray is cracked, distorted, or repeatedly lifting. Facial swelling or fever requires urgent assessment.
Does the pain mean the tray needs adjustment or delay?
Ask whether the pain matches expected tooth movement, whether an edge needs smoothing, and whether the next tray should be delayed while the tooth or appliance is checked.
