If a player has orthodontic braces would it be possible for their dreamself to not have them? Also if they ascended to God tier then would the braces disappear too?

Depends? Wounds and other such things seem to disappear upon ascension, but think of Terezi’s Blindness- It’s technically a disability, but she heavily regrets seeing after getting healed by Aranea, I don’t think going God Tier would let her see again. Like… Someone who’s shy and doesn’t like their braces may get their teeth fixed, but if they’re confident about the look or don’t quite care, they may not.
