I am not an expert but this happened to a good friend of mine. Her son was 3 when it happened & it did bleed ALOT and became swollen but I know they did not take him to the ER or doctor. They iced it & gave him pureed and/or soft foods. He was grumpy for a few days and did not eat as much but he returned to normal. Sometimes it looks worse than it is. If you are worried you could always call your doctors emergency line & see what they say. Good luck!
