Hello Sir,
The radiographs reveals an impacted wisdom tooth i.e not completely erupted and positioned in a manner to cause food lodgement.
Extraction for the third molar would be advisable, but regarding the risk of paresthesia, it would be wise to comment only after an additional CBCT radiographs (3D X ray). As the present X ray could be a misleading one being a 2D X- ray.
Regarding treatment plan for 7 i.e the second molar we would want to comment only after a clinical check up.
Kindly visit the clinic for further evaluation and queries.
Next Steps
CBCT for the third molar for evaluation of proximity to the nerve.
Clinical check up for treatment plan with 47.
Health Tips
The problem of food lodgement will only propagate the cavity with 47 i.e lower right second molar. Kindly get it addressed at the earliest.
