When you start to wear a new set of aligners, it’s common to feel a bit of discomfort or minor pain for the first few days. Remember that your teeth are moving and shifting into a new position. Continue to wear the aligners and you will find that the discomfort resolves after a few days. People often find that invisible aligners are less painful and more comfortable than traditional braces because you don’t have brackets and wires that cause sore spots on the inside of the lips and cheeks.
