OK to Get Invisalign out of State While in College?

Its best to get your treatment done in the area where you'll be living for at least 12 months. Retainers can be mailed to any location.

Since you have many visits you should see a dentist close to where you will spend most of your time.  Also prepare for 4-8 visits about every 6 weeks until the treatment is done.  You won't be able to start until about a month after your impressions, so you will have to plan on how much time the treatment will take and how long you may be gone during summer vacations.

Personally I would say don't start it unless you can finish it with the same person who begins it.

The process is not immediate, and is impossible to start on the first visit (wearing trays).  The initial consultation is when records can be taken, but those must be sent to Invisalign.  After a few weeks, the computer rendition is ready and roughly 4 weeks later the aligners are done.  Usually 3 aligners are dispensed at a time, wearing each for 2 weeks.  Appointments 6 weeks apart are scheduled until completion of care, and total time varies from case to case, IF Invisalign is possible.
