There is one I created for braces. Not very active but available

I would like to go there too, please!

I found the following one:
Orthodontics Worldwide: https://dereferer.me/?https://discord.gg/69zhqqgQ

FYI from the rules:

Note that the "Orthodontics" area is an area where we EXPECT to see under-18s, so no 'naked women' images. The 'Enthusiasts area is 'over-18's', put the naked women in there - by preference, they should have braces, of course! Use the NSFW area for anything... well, NOT suitable for general viewing.

To get the enthusiast role, you need to go to "select_roles" in the lobby and make your choices accordingly.
