Can lip ties grow back?

So my husband and i were the car talking about random stuff when he said you "did you know that I dont have the skin attached under my lip?" I was like huh? He showed me and I was thinking he probably got it clipped when he was a baby? Even though he insists he tore it when he fell as as kid😂 lol so who knows.🤷 His mom had a total of 10 kids and she breastfeed most of them i think. He wasn't born in the states either so im not sure what kinda practice was done. I just think it's kinda funny how he said it. And now I just wonder is the skin supposed to grow back?
