Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems the due to traumatic
injury there has been injury to the labial
frenulum that is a mucosa fold that connects the inside of lip with the gums..
As the blood supply of the oral cavity is very profuse you can get it the healing tends to take place very faster..
In case if there is a cut inside mouth or the mucosa or frenulum seems to be hanging you can consult an Oral Physician and get evaluated and get treated accordingly..
As of now if there is pain you can give him
tylenol or
Ibuprofen for relief..
Application of Lignocaine gel can help in numbing the area and provide relief..
Doing cool compresses can also help in reducing inflammation..
Apply antimicrobial ointment for preventing infection..
Hope this information helps..
Thanks and regards.
