Dallas Invisalign doctors

If you move out of the area and need a new dentist or orthodontist to complete your treatment, your current dentist can transfer the aligners and contact Invisalign about the "changeing of the guard."  At the end of your treatment period it is common to want to order refinement aligners to further improve your smile.  It is important that an invisalign trained professional remove the "buttons" bonded onto your teeth and makes retainers at the end of your treatment. 

Although all aligners are made and delivered to the dentst at  once, it is best to have the dentist monitor the fit and movement of the teeth during the treatment time.  It is common to order refinement aligners to enhance the final appearance of your smile.  If you are leaving the area of the dentist with whom you started, it is possible for him/her to release your case to another dentist who can follow up on your case and ensure great results.

You seem to understand the concept of Express well.  The financial arrangement of $2750 is below the cost of Express in all the offices that I'm aware.  Your dentist seems to be really trying to make the cost as low as possible - although his/her cost are higher with the 11 tray lower arch.  They are paying Invisalign (Full) the higher cost for your case.

Congratulations on finding a great deal for your orthodontics.  You should always openly discuss anything with your dentist!
