What is the direct answer?
Invisalign aligners can cause pressure or tenderness when a new tray moves teeth, but significant or persistent pain should be reported.
What does this question mean?
Clear thermoplastic trays apply controlled force through the periodontal ligament; sharp edges, poor fit, or tooth disease can cause a different pain.
What can you do next?
The orthodontist checks bite, movement, gum health, attachments, and fit; treatment cost depends on complexity, stages, refinements, retainers, and follow-up.
When should you seek dental care?
Wear aligners as prescribed, remove them for eating and cleaning, and do not cut or reshape a tray without advice.
What should you ask the dentist?
Contact the orthodontic team for severe pain, a tray that will not seat, a sore from an edge, swelling, fever, or unusual looseness.
