Hello,
Mesio angular teeth usually cause problems like pain, food lodgement issues, decay not only in the wisdom teeth and the tooth in the front, it may also cause alignment issues due to the pressure it exerts on the other teeth.
So it may be asymptomatic now but may cause symptoms in the future, you may need to get it extracted.
Keep an eye on other symptoms mentioned and not just pain.
The procedure is done under local anaesthesia so it doesn't hurt during the extraction, you may feel a little pressure and tingling sensation.
After the procedure there may be a little discomfort, pain and swelling but manageable with medication.
Next Steps
Get an OPG and consult with your dentist whether waiting is an option for now.
