Hello
I would like to inform you that based on your history and radiograph it seems like ur 3rd molar is impacted, and will not erupt normally. That is the main culprit for pain, so better to remove that ASAP. meanwhile u can have salt water saline gargles to reduce pain over gums.
Bcoz of 3rd molar only , u might not be able to keep ur backside clean so 2nd molar has developed cavity and quite deep. So better to go for root canal treatment of same.
Next Steps
extraction of 3rd molar
RCT of 2nd molar
Health Tips
