Why can new Invisalign aligners cause pressure and tenderness?

Clear aligners move teeth by applying controlled pressure through the plastic tray, so pressure, tenderness when biting, or a sore spot can occur. A sharp edge can also rub the cheek or gum.

How can you tell normal pressure from a tray problem?

Normal movement discomfort is usually dull and pressure-like, while a single sharp area often points to a rough edge, poor fit, or an attachment irritating tissue. Severe pain is not a target of orthodontic treatment.

When should severe Invisalign pain be checked?

Ask the orthodontic team to check pain that is severe, localized, worsening, or still present between tray changes. Swelling, a loose tooth, or a damaged tray also warrants contact.

What should you ask about the cause of aligner discomfort?

Is the discomfort from tooth movement, an attachment, or a tray edge, and should the current aligner be adjusted or replaced?
