My four year old son has two bump things you supposed to bust on his gum line and after you bust them they bleed.it's above his two front teeth that happens to have cavities they need to be removed but my husband said don't take the kid to the dentist because they will come out naturally but every time I bust them little things they bleed a little the puss come out and then I clean his mouth with peroxide and mouthwash then a week later it comes back what do I do
