What you need to know about Invisalign
With Invisalign, you are given a series of clear aligners that move the teeth over time. You switch to a new clear aligner approximately every two weeks. Every time you switch to a new aligner, you will feel some pressure on some of the teeth and the teeth may feel slightly tender for the first few days, but the tenderness goes away quite quickly. Most people would say that Invisalign is not painful, but it does cause slight tenderness of the teeth initially.
