As a Wearer of Invisalign over Age 60, What Problems Would One Have As I Age?

You mentioned that you see your dentist on a regular basis every six months.  If you need to have dental work done ,such as an extraction or crown down the road, your dentist will watch the teeth for movement and make adjustments to your retainer or create a new retainer to fit the changes in your teeth.  As long as you see your dentist on a regular basis and wear your invisalign retainer as much as possible, your teeth will always look great!

Since you visit your dentist every 6 months, I assume you and your dentist are keeping things really healthy.  If you are free from periodontal disease (gum disease, bone loss), and your teeth are healthy, then there is no reason not to do Invisalign.  In fact, if your teeth are crowded, Invisalign will actually help the health of your gums - making them easier to clean as you get older when your manual agility may decline.  If you use Invisalign retainers, you will get a new set every 4 months (to keep your teeth in the ideal position) - and you pay for them yearly (usually under $400 per year)...so if you get a new porcelain onlay or filling, you can have new impressions made so that a new retainer can be made under this program.
