If you're wearing Invisalign clear braces and experience an emergency, there are a few steps you can take to help alleviate the situation. If you have an ulcer inside your mouth due to the aligners, rinse the area with warm salt water to clean the sore and prevent it from getting worse. You can also use a clean nail file to apply it a little to the sharp area, but be careful not to file the aligners too much or you could distort their shape and make them less effective. Additionally, if you're experiencing gum and cheek discomfort or irritation due to the aligners having a slightly sharp or serrated piece of plastic or acrylic along the edge, you can use a clean nail file to correct small sharp spots on the aligners. If you've gotten used to wearing your traditional orthodontic appliances or transparent aligners, it's important to take all necessary precautions to avoid any potential problems.
Taking these steps can help ensure that your braces remain effective and that any emergency situations are quickly resolved.
