Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that as you have a large hole in the tooth along with pain and swelling over the gum and has became severe and spread over the face along with
radiating pain in head and eye pressure.
Well, all of the symptoms are indicating towards
dental abscess that occurs when the infection from tooth spreads deep to the root canals and below the root tips of tooth and forming pus..
The pus perforated the bone and gets accumulated in the soft tissues leading to swelling..
Taking antibiotics in such cases can reduce infection and swelling to some extent only..
For permanent resolution you need to get the tooth treated..
You should consult an
Endocrinologist and get evaluated and a thorough clinical evaluation and investigations like xray can help in diagnosis..
In case if tooth can be saved
root canal treatment of tooth followed by a course of antibiotics and painkillers will help..
In case of extensive decay extraction of tooth will be the last option..
Hope this information helps..
Thanks and regards.
