Hi..
Thanks for the query..
As per your complain it seems like there is formation of
dental abscess due to deep Infection in tooth leading to accumulation of pus below the root tips of the tooth causing swelling and pain..
At times the pus perforates the bone and gets accumulated under the soft tissues leading to swollen lump and when the inflammation and infection increases there can be swelling over the face/ cheek in the area adjacent to the infected tooth..
It should be confirmed by getting an
x ray of the tooth done under supervision of an Endodontist....
In case if it is an abscess and tooth is in a condition to be saved then
Root Canal Treatment of tooth followed by antibiotics and painkillers will help..
In case of deep decay extraction of tooth will help in complete resolution..
As of now consult an Emergency room and get evaluated and a prescription of antibiotics like
Augmentin and anti-inflammatory painkillers like
Ibuprofen along with Serratiopeptidases will help in reducing pain and swelling..
Do cool compresses over the swelling..
Hope this helps..
Regards..
