Invisalign treatment can still be done if there is a missing tooth/teeth. The treatment plan usually involves closing the space or even opening or maintaining the space for a future implant or bridge placement. This will ensure the size and shape of the implant, crown or bridge is as ideal as possible.
During the treatment, a tooth coloured material can be placed into your aligner to conceal the empty space such that there are no obvious gaps while you are wearing your aligner.
However prior to starting your Invisalign treatment, it is important to consult your attending dentist to identify the cause of your missing teeth - is it due to gum disease or extensive decay? All issues should be addressed before starting your Invisalign journey to ensure a successful outcome.
