Does it hurt to have braces or Invisalign?

As someone who’s had both braces and Invisalign, I can tell you honestly that with both there is some discomfort, mostly at the start of treatment.

Invisalign is a little more gentle (in my experience).

Moving teeth is a bit like push starting a car – it takes a fair amount of force to get things going, but once they’re moving, things move fairly easily.

It is generally not “painful”, but things can feel a bit bruised or uncomfortable for short periods of time.

Sometimes the brackets from your braces can put pressure on or scratch your lips and tongue a bit. Sometimes you can get some ulcers or “blisters”, like when you wear a new pair of shoes, and just like shoes, this generally settles down after a week or so.
