Hi, may I answer your health queries right now ?  Please type your query here...my 7 year old has a red bump that has gotten larger and looks to be filled with fluid and blood- under his top lip on his gum above a tooth. i thought a popcorn kernal might be trapped but no and now it has doubled in size over the week.
Hi. Welcome to Chat Doctor . I have gone through your query and can understand. As per your complaint it seems that there is an abscess formation on the gum above the tooth and can be either due to deep infection in the gum leading to formation of a gum abscess while can also be due to decayed tooth due to which infection has reached below the root tips of the tooth leading to pus formation. At times the pus perforated the bone and get accumulated in the soft tissues leading to formation of a painful lump. Consult a Periodontist and get him evaluated, and he can do an x-ray to check for the exact cause of the lump. In case if it is due to gum infection then deep scaling followed by antibiotics can help. In case of tooth infection root canal treatment will be done. If the lump is large then Incision and Chat Doctor. . Hope this information helps. Thanks and regards.
