Hello !
Most likely you could have an impacted /partially erupted wisdom tooth.
Incase of severe pain I'd advise you to visit the dentist for a x-ray and medicinal prescription.
On Xray if it is impacted , you would need to get it extracted soon to avoid pain and damage to adjacent tooth.
Next Steps
maintain good oral hygiene around the erupting wisdom tooth
