hello and welcome to HCM
The symptoms that you have mentioned are more suggetive of an erupting wisdom tooth.
The age, site and charater of pain favor a wisdom tooth.
Vist your dentist
for a x-ray. The X-ray will help the dentist to know whether the tooth is erupting straight or is twisted or turned.
The wisdom tooth is known to be impacted or erupting is different directions.
In case it is impacted it will have to be extracted surgically.
You can take saline gargles for relief of the symptoms and avoid chewing from that side.
Thanks and take care
