What will the dentist replace the two teeth he pulled with?

You have (possibly) 4 options

1. do nothing, leave a space, and don't replace the teeth

2. possibly a "bridge" or a "fixed partial denture" (FPD)

3. possibly a "plate" or a removable partial denture (RPD)

4. possibly an implant(s) with a crown

The answer depends on a variety of factors and will need to be discussed with your dentist. Not all options work in all circumstances.
