Misalgined Bite with Invisalign?

Many times it is entirely normal for your bite to feel completely out of alignment and uncomfortable as you are going through orthodontic tooth movement. Certainly when you start with your first trays of Invisalign, it is not uncommon to feel your bite changing, which might feel awkward and uncomfortable. Give it time. However, since you mentioned being treated with Invisalign Express 5, the degree of your malocclusion must be minimal to be treatable in only 5 aligners. Discuss your discomfort in your bite with your orthodontist so that you can be reassured that it is normal for your situation.

It is not uncommon to feel that your old bite is changed. Your teeth and jaws had gotten use to your bite. The trays are changing both of these elements. Things will feel different. Do not keep trying to find your bite you will just make your teeth sore. In due time you will become comfortable with the bite changes. At the end of treatment you will look great and also feel great. If any questions always talk to your Dr

Don't be alarmed with changes during treatment.  When all is done, you should be pretty close to normal and once you have been out of the aligners for a few months your bite should feel like your own again.
