Invisalign aligners are removable so you can play sports without worrying about causing damage to your aligners.
However, keep in mind that Invisalign aligners must be kept in your mouth for a minimum of 22 hours a day, so you will need to plan your time carefully.
Since orthodontic treatment can cause your teeth to loosen slightly as they shift into their new positions, your teeth can susceptible to damage. Therefore, you may also want to invest in a sports mouth guard to protect your teeth.
