Invisalign discomfort is usually mild and temporary. Most people feel pressure when they start or switch aligners, but this settles within a few days.
Invisalign is popular for straightening teeth without metal braces. It uses clear, removable aligners that gently shift your teeth into place. Many patients ask whether Invisalign hurts, especially at the beginning of treatment. This guide explains what discomfort to expect, why it happens, and how to manage it easily.
