My son has a very loose tooth. He also has extreme anxiety over losing teeth. Somehow this thing has been hanging on for over a week now & is going on almost a week of being totally sideways. Just curious what the red tissue is that's developed above the tooth? It wasn't always there. Could it be like a little blood blister or just simply some swollen tissue? Not really concerned, just curious!

Thank you!
