Pressure
Mild tooth pressure is expected as a new stage begins, but intense localized pain or a tray trapped by an attachment should be reported.

Your first week with Invisalign
The first week is mainly about learning technique and routine. Pressure, extra saliva, minor speech change and attachment awareness are common, while severe pain or a tray that cannot seat deserves attention.
The plain answer
The goal is not zero sensation; it is a manageable adjustment with correctly fitting aligners.
Learn removal from the back teeth, use the case every time, practice seating the trays fully and plan softer foods if teeth feel tender. Speech usually adapts with normal talking and reading aloud. The aligner edges should not create persistent cuts.
Before leaving the delivery visit, demonstrate insertion and removal, confirm the first change date, know how to use chewies if prescribed and save the office's after-hours instructions.
What matters
Three things to evaluate before acting
Technique
Removing from the inside of the back teeth and working forward usually reduces strain on attachments and the tray.
Routine
The first week is the right time to fix meal timing, cleaning supplies and safe tray storage before habits become inconsistent.

Where this fits
Make treatment work in ordinary daily life.
The Live it stage is where outcomes are protected by routine. Aligners must be worn as directed, removed safely, cleaned sensibly and kept away from heat. Tracking problems, lost trays or unexpected discomfort should be reported rather than hidden until the next scheduled visit.
Do not repeatedly remove aligners just because they feel tight. Frequent removal reduces wear and can make insertion feel more difficult. Do not file or heat a tray unless the treating office instructs you.
Questions people ask
Useful answers before a consultation
Will Invisalign affect speech?
A slight lisp can occur initially and usually improves as the tongue adapts. Persistent or severe problems should be discussed.
Can I use pain medication?
Ask your treating clinician or pharmacist about what is appropriate for you, especially if you have medical conditions or take other medication.
What if the aligner edge is sharp?
Contact the office for guidance. Orthodontic wax or careful professional adjustment may help, but do not reshape the tray aggressively yourself.
