From x ray point of view both tooth & the RCT done is totally fine, there is horizontal bone loss around both teeth, food accumulation interdentaly may cause pain & swelling of gums, if u hav already done scaling u can just maintain good oral hygiene (brush twice,rinse mouth with warm salt water 5-6 times a day for next 3 days. Use interdental brush to clean proximally. Any injury during scaling in 47 may trigger pain. 46 if it was touched unnecessarily i think u need to look at 48 if it exists,extract it if needed since ur case might be referred pain. Mostly u ll do just fine with this 🙂
Next Steps
warm salt water gargling 5 times a day.
rinse mouth after every snack meal.
use interdental brush between teeth & gums.
clinical examination of 48 & extract even if there is lowest level of doubt.
