How Long After Invisalign Do I Need a Retainer?

Retain only the teeth you want to keep straight.  This statement reminds me of the bad dental joke "You only have to floss the teeth you want to keep!"  Although there is a lot of truth to these statements, wearing of an Invisalign retainer should not be a big issue as a big advantage of Invisalign treatment over braces is their great comfort. Usually the first couple years, you wear your aligners each night and then can taper down to one to two nights a week.  I personally have worn both braces and Invisalign at different times and there is no comparison in comfort levels.  So if you are a candidate for Invisalign (not all are), the see your orthodontist and get it going. 

First, you are a very pretty women just as you are.  If you do want to improve your smile I suggest instead of moving teeth you consider orthopedically growing your jaw using the DNA Appliance and Epigenetic Orthodontics. The DNA is only worn 12-14 hours a day and does not need lifetime retention.It will also help the dark areas under your eyes.It will create a wider fuller smile as well.

The retention phase of treatment comes after tooth
movements using the aligners have been completed.
Due to the tendency of teeth to shift in the human
dentition, you can expect that your teeth will
naturally begin to shift back to their original position
once your prescribed course of clear aligner treatment
is complete. For this reason, retention is a lifelong
commitment and you MUST follow the retention
instructions prescribed by your doctor. some instances call for a lingual bar that is bonded to the back of your front teeth. These are rigid metal
reinforcements placed behind your teeth to prevent
them from moving. In addition, you will need to wear retainers
indefinitely until your doctor tells you that you no
longer need them. Retainers are typically worn full time,
at least 22 hours a day, for the first few weeks to a few months of use.
After that initial retention time, you may, with permission
from your doctor, start to decrease the amount of
time during which you wear your retainers by
approximately two hours a day for each week.
After a few months of gradually wearing the retainers
less frequently throughout the day, you may, with
permission from your doctor, begin wearing your
retainers at night only. Please keep in mind that
decreasing the amount of time during which you
wear your retainers depends on the retainers being
comfortable and loose when placed in the mouth. If
your retainers feel tight or you feel pressure, you
must revert back to and repeat the schedule of the
previous week.
You must wear your retainers every night for the first
year of use. After the first year, you may, with
permission from your doctor, begin wearing them
every other night, provided that they are loose and
fitting well; otherwise, you must continue to wear
them every night. You should bring your retainers to all future followup
appointments so that your doctor can assess their
fit and function and make adjustments as necessary
