Why does the while wait() loop only run one time?

function SaveData(character)
	local Data = {}
	local DaPlayer = Players:GetPlayerFromCharacter(character)
	character.Humanoid:UnequipTools()
	for i, v in pairs(DaPlayer.Backpack:GetChildren()) do
		if v:IsA("Tool") or v:IsA("LocalScript") then
			table.insert(Data, v.Name)
			print(v.Name)
		end
	end
	local UserId = "Player_"..DaPlayer.UserId
	local succ, err = pcall(function()
		DS:SetAsync(UserId, Data)
	end)
	if succ then
		print("Data Saved Sucessfully to"..DaPlayer.Name)
	else
		warn(err)
		print("Problem saving "..DaPlayer.Name.."'s Data")
	end
end

function teleport(Array)
	local ReserveCode = TS:ReserveServer(6981160086)
	TS:TeleportToPrivateServer(6981160086, ReserveCode, Array)
end

while wait() do
	for i, v in pairs(workspace:GetChildren()) do
		if v:FindFirstChild("Bending Sense") and v:FindFirstChild("MatchMaker") then
			table.insert(Potentials, v.Name)
			print("Added A Potential 1v1 Contester")
		end
	end
	if Potentials[2] ~= nil then
		print("Found Players to Teleport To Arena")
		local Chooser = math.random(1, #Potentials)
		local Character2Name = Potentials[Chooser]
		local Character2 = game.Workspace:FindFirstChild(Character2Name)
		repeat wait()
			local Chooser = math.random(1, #Potentials)		
			Character1Name = Potentials[Chooser]
		until Character1Name ~= Character2Name
		local Character1 = game.Workspace:FindFirstChild(Character1Name)
		SaveData(Character1)
		SaveData(Character2)
		wait(3)
		--wait(100)
	    Player1 = Players:GetPlayerFromCharacter(Character1)
		Player2 = Players:GetPlayerFromCharacter(Character2)
		local Array = {Player1, Player2}
		teleport(Array)
		Player2 = nil
		Player1 = nil
		Potentials = {}
	else
		Potentials = {}
	end
end

use

while true do
	wait()
	--stuff here
end

While wait() do does not work because you need a condition which returns true or false to either keep the look running or end it.
