If you're considering braces or Invisalign to straighten your teeth, you may wonder if you can still get treatment if you have missing teeth. The good news is that Invisalign can be used with missing teeth. However, there are a few things to keep in mind. First, if you're missing any back teeth, your dentist or orthodontist will need to place spacers in the empty spaces to ensure that your braces or Invisalign aligners fit correctly. Second, if you're missing any front teeth, Invisalign will temporarily replace the missing teeth with a moulded tooth attached to the inside of your aligners so nobody can see the gaps.
