After Invisalign Treatment Will My Teeth Revert Back To Pre-Tx?

When we move teeth either with Invisalign or with normal braces, the teeth have a tendency to want to move back to their original position.  This is why long term retention is very important.  You must discuss the retention options with your doctor before starting the treatment.

As mentioned by all the doctors,  some type of retainer is needed  to prevent relapse of tooth movements.  There are many types of retainers including wires that can be attached to the back of the anterior teeth to hold them in place.  Also all types of plastic retainers can be worn at night to hold the teeth in place and these include very thin vivera retainers from Invisalign that must be replaced every so often.  Discuss this well with your dentist before you start and as you are getting ready to finish.  I tell all my patients that the only way to keep their teeth from moving sometime in their life is to wear some type of retainer for the rest of their life. 

While teeth likely will not revert all the way back to where they started, if a person does not wear a retainer after orthodontics (Invisalign or brackets and wires) teeth will not stay put.  Once teeth are straight, the improved alignment should result in better chewing, so you should be able to eat as usual.

Chance of being worse that before?  Not likely.
