Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain and presentation of symptoms if you have only sensitivity in the canine and not pain then it can be due to a condition known as DENTINAL
HYPERSENSITIVITY and it happens due to opening of the nerves leading to sensitivity with even minor stimulation ..
In this condition application of a Desensitizing toothpaste atleast two to three times a day for 15 days can help..
In case if there is no improvement then you should
consult a dentist and get evaluated and get an IOPAR[ X-ray] done to rule out the exact cause like
dental decay and treatment can be planned accordingly..
If the infection is superficial filling of the tooth can relieve..
In case if the infection has involved the nerves then
root canal treatment followed by capping of tooth can help..
Hope this information helps..
Thanks and regards..
