Invisalign is the CLEAR way to STRAIGHTEN teeth. Invisalign gradually moves teeth through a series of custom made, removable, nearly invisible aligners. Straighter teeth can lead to: healthier gums, easier cleanings, improved chewing & speech, decreased risk of dental trauma & more beautiful smiles. The benefit of Invisalign over traditional orthodontics is that it can be removed for eating and cleaning teeth. They are removable.
