Hi name is chad I have a broken wisdom tooth and have had no problems with it I just noticed on the outside of my jaw in line with the broken tooth there is a hard kinda lump that runs down and under my jaw its tender when I push on it hard but not painful in any other way there is no paid. When I eat or put pressure on the tooth I am just wondering what this could be and if I should think of it as a life threat
Hello there, Thanks for writing your query, According to your history I can suspect your broken wisdom tooth has undergone bacterial infection due to food lodgment or improper oral hygiene. The infection has gone worse, and you have developed a periodontal abscess due to spread of infection to the underlying tissues.  The hard lump under the jaw is nothing but the spread of infection to the jaw bone. You need to get an x-ray done the affected area to confirm the presence of infection, approach a dentist for the treatment.  I would suggest you to start with an antibiotic and analgesic course consulting your dentist, which helps in subsiding the swelling and relives pain.  I hope this helps, take care.
