During Invisalign treatment, my tooth moves after clenching. Is it normal?

Hi, Welcome to icliniq.com. Clenching of tooth is not an uncommon habit and 75 percent of world population do it. I am glad to hear that you are aware of clenching your tooth. There are some best non-pharmacological ways to manage it. Do not clench hard as it deteriorates your jaw joints in a long run. Kindly note the triggering factor that makes you clench and try to solve it by doing meditation or simply open your jaw and wiggle when you clench your tooth. Invisalign is designed to move your tooth. I think that you have mixed both clenching and grinding. Clenching gives muscle pain and grinding makes teeth flat. Apparently, all teeth move a little bit every time but definitely, they do not cause loosening of tooth. This is referred to as physiological migration. Do not be stressed. Consult your dentist for further examination.
