Can Invisalign make your teeth feel sore or pressured?
Invisalign can make teeth feel tender or pressured, especially after a new tray, because the aligner applies force to move teeth.
How do clear aligners apply force to move your teeth?
Invisalign is a series of custom thermoplastic trays that press selected teeth toward new positions. Pain may also come from a sharp tray edge, an attachment rubbing the cheek, decay, or a gum problem rather than tooth movement itself.
What can you do when new aligners make chewing tender?
Wear the tray as prescribed, use a soft diet briefly if chewing is tender, and inspect the plastic for a rough edge or crack. Do not trim the tray or stop treatment for repeated discomfort without contacting the treating orthodontic team.
Which tooth pain symptoms need an orthodontic review?
Arrange dental review if pain is severe, localised to one tooth, associated with swelling, fever, a loose attachment, a tray that does not seat, or a sharp edge that keeps injuring tissue. Urgent care is needed for facial swelling or trouble swallowing or breathing.
What should you ask about pressure and how your tray fits?
Ask whether the pressure matches the planned movement, whether the tray is seating fully, and whether an attachment or tooth needs examination. Also ask what adjustment or pain-relief option fits your medical history.
