Some people experience mild discomfort or soreness when they first start wearing Invisalign aligners. This is normal and can be caused by the pressure that the aligners exert on your teeth as they gradually shift them into the desired position. This discomfort can be managed with over-the-counter pain relievers or by applying orthodontic wax to the aligners to reduce friction.
Most people find that the initial discomfort subsides after a few days to a week, as they get used to wearing the aligners and their teeth adjust to the pressure. Some people experience no discomfort at all during their Invisalign treatment.
It’s also worth noting that Invisalign is typically considered to be less uncomfortable than traditional braces, which can cause mouth irritation and soreness, especially when the braces are tightened during regular adjustments.
