Most people enjoy Invisalign because it is more convenient than ordinary braces:
Over several months, Invisalign can completely resolve many problems with tooth alignment. Invisalign is effective for straightening teeth and correcting their relative position. Only the most serious cases of bite misalignment, such as those caused by bone structure issues, are not affected.
Invisalign doesn’t just improve the look of your smile. By fixing tooth alignment issues, you also strengthen your teeth. Straighter teeth more effectively distribute the force of the bite, which can make chipping, cracking and other tooth trauma less likely in the future.
During the first few days, patients may feel slight discomfort when wearing spacers. After getting used to them, mild irritation to the gums or other soft tissue is the most common issue.
Invisalign may be uncomfortable for a short period after you first start using them. Luckily, the sensation is much less noticeable than with traditional metal braces. Any discomfort should fade within about two weeks of starting treatment. If not, the spacers may be the wrong size for you.
In rare cases, allergic reactions to Invisalign have been reported. Invisalign spacers are made using plastic, and this can cause an unexpected reaction even in people who have not reported any allergies before. Discontinue use and talk to a dentist if you notice severe gum irritation.
