You cannot restore the old match, chat, or messages. Tinder says an unmatch is permanent. The Help Center pages on unmatching and Discovery do not say whether the same two people can match again later, even if she appears in Discovery.
The old match does not come back
Tinder says an unmatch removes both people from each other's match lists. The person is not notified, though she may notice that the chat is gone. Tinder also says the action is permanent, including when you tap it by accident. The Help Center says it cannot be reversed, so the old match cannot be restored.
That answers whether you can undo the old connection. The unmatching page does not settle whether the app might show the same person again at some point. The Discovery pages describe separate cases where profiles may appear again.
A card can appear again for another reason
Tinder says someone whose account disappeared may show up in Discovery if she deleted her account and later returned. It also says a profile you already tapped through may appear again. Tinder gives two reasons: the person deleted her account and came back, or your connection was poor while you were swiping.
Those notes explain why a profile might appear again. The Help Center pages about profile reappearance do not say that every person you unmatched will return to Discovery or set a wait. They also do not say that a returned profile brings back the old chat. A card appearing on your screen is not the same thing as the old match being restored.
Tinder leaves the later-rematch question open
The Help Center page about unmatching says the action is permanent. The Discovery pages describe account deletion and a poor connection. Those Help Center pages do not say whether someone you unmatched might appear again. They do not explain whether an unmatch works like a person you simply tapped past.
So the accurate answer has a limit. The Help Center page calls an unmatch permanent and says it cannot be reversed. The Discovery pages do not promise that the same person will reappear or settle whether a separate match can happen later. Saying yes or no with certainty would go beyond what those pages explain.
A later match would be a separate connection
Tinder says a Match happens when you Like someone and they Like you back. If you see her in Discovery and you both Like each other, that would be a separate match. This follows Tinder's general rule. It is not a special rule for two people who have unmatched.
A later match would not restore the old chat or its messages. You would be starting with a separate match, and the Help Center pages checked do not say whether either person will see the other again. If you see her, do not read that as proof she wants to reconnect. It only means the app has shown you her profile.
Search and blocks do not create a way back
Tinder's Search page says Search is for shared interests and is not designed to locate one person by name or social handle. The Help Center pages checked do not describe deleting or restarting an account as a way to restore an unmatch. Do not change your account to force someone's profile to appear.
A block is different from an ordinary unmatch. Tinder says its Block Profile feature prevents the two profiles from seeing each other and cannot be undone. If someone blocked you, or unmatched you and chose to block your profile, do not look for a way around that choice. If she ended the match, leave it there.
The practical answer
Tinder's Help Center says an unmatch is permanent and cannot be reversed. The Help Center pages checked do not say whether a person who returns to Discovery after deleting an account can form a separate match with someone who unmatched them. If you happen to see her through normal Discovery, any mutual Like would be a separate match. Do not count on it, and do not try to make it happen.
