Do Invisalign braces hurt?

Teeth move in response to forces placed upon them. Constant force pushes a tooth against adjacent ligaments and creates inflammation. This is kind of like a "Charlie-horse" next to the tooth. This inflammation causes your mouth to respond by changing the shape of the bone in the area of the inflammation. After the bone remodels and circulation is restored, your soreness will go away. Teeth cannot tell the difference between force caused by metal braces or plastic aligners. Your teeth will be equally as sore using braces or Invisalign.

Invisalign braces are just another type of orthodontic appliance used to create a constant force on the teeth in order to move them. When worn correctly they will move the teeth. Anytime teeth are moved the body produces chemicals to help the teeth move and the bone remodel around the teeth. These chemicals, while helping the body move the teeth will also produce soreness and sensitivity around the teeth.
