Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain as you have recurring excruciating pain in wisdom tooth and the pain is severe enough along with filling in the canine, there is a possibility that there is secondary decay in the tooth and it has reached the nerves of the tooth along with reaching below the root tips and causing pus formation, that is a
dental abscess..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and
x ray can help in diagnosis and treated accordingly..
In case of deeper decay you can be advised to get
root canal treatment of tooth done followed by antibiotics and painkillers..
As of now you can take painkiller like
Ibuprofen to relieve pain..
Do cool compresses over the area of nose..
Take a
soft diet and avoid very hot or very cold foods..
Hope this information helps..
Thanks and regards.
