<s>[INST] My son has a big bump on gum on top of his front tooth . It s grown even bigger today and shows a little white dot. My son is 3 with no teeth lost yet but his teeth are rotting. What is this? I went ahead and try to push in it. Gross it was gushing liquid. Put some dental relief on it. It looks better but it s still big! U think the surgery to take it out is necessary? It s going cost me $2000 with my insurance. That s alot. [/INST] Hello and thank you for your questions. The bump you are describing is an abscess.  You need to have your child brought in to a dental clinic to have the infection removed via extraction of the teeth or root canal therapy and possible antibiotic therapy.  Are you brushing and flossing your children teeth?  His oral health today will affect his oral health tomorrow.  You may be putting him to bed with other fluids besides water.  Water should be the only thing that a child goes to bed with.  Anything else will rot their teeth (baby bottle rot). If your dentist is costing you $2000.00 on top of insurance coverage for a tooth extraction, I highly recommend getting a consult by another dentist.  This sounds extremely high. Do not sit on this problem with your child.  Since his condition and age, not seeking immediate attention can be considered child neglect and state services can get involved. Best wishes! </s>
