Hi..
Thanks for the query
As per your complain
sore throat can be seen associated with wisdom tooth related infection and inflammation as the area of wisdom teeth is very close to throat and inflammation from wisdom tooth can even make the throat sore and painful..
But runny nose is not commonly seen with sore throat if it is related to wisdom tooth and can be due to other causes like
Sinus Infection or
upper respiratory infection..
So for this you can consult a Physician and get evaluated..
For tender gum around wisdom tooth that seems to be due to
Pericoronitis which is inflammation of gum flap due to food accumulation and Infection between gum flap and tooth..
Whether tooth is impacted or not can be ruled out with x-ray..
For this consult an Oral Physician and get evaluated and an x-ray of the tooth will be done..
First of all to reduce infection the area will be irrigated with antiseptic solution followed by a course of antibiotics like
Augmentin and anti-inflammatory painkillers like
Ibuprofen..
Warm saline gargle will also help..
Once the inflammation reduce then if the wisdom tooth is not impacted then it will be left to erupt..
In case if the tenderness recurs then the gum flap will be removed to prevent recurrence..
If the tooth is impacted then extraction is the best line of treatment..
Hope this helps..
Regards..
