<s>[INST] Hello, My 5 year old daughter was hit in the mouth.  She was pulling on the dog leash and the collar came off the dog, and the metal part of the collar swung back with a lot of force and hit her on the outside of her mouth and the inside of the mouth.  The outside has a tiny puncture...the size of a pin head....and it is a tiny bit red and swollen.  The inside had a 1/4 inch puncture.  It stopped bleeding so I did not take her to get stitches, but now it has turned completely white...the cut and the area around it.  What should I do? [/INST] Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint it seems that there has been torn in the mucosa due to trauma that can be due to hitting with the teeth leading to a cut. As a quarter inch cut does not need to get stitched and also the blood supply of the oral cavity is profuse that any injury gets healed very quickly. The would when heals continuously changes its color and a pale or whitish appearance is not to be worried about, and it must e a phase of healing. You should apply antiseptic oral ointment over it and do cool compresses. Make her gargle with antiseptic mouthwash suitable for kids. Apply antiseptic ointment over the pin head cut on the outside too to prevent it from getting infected. In case if there is an increase in pain or swelling both inside and outside mouth then you must consult an Oral Physician or a Periodontist to get her checked for infection. Hope this information helps. Thanks and regards. Chat Doctor.  </s>
