Hello Sir,
Greetings for the day.
According to the OPG there is deep decay on the upper left first molar nd lower right second molar.
Treatment for upper left first molar would be Root Canal Treatment followed by a crown.
While for the right lower second molar would request you to get a localised X ray which would help us to decide whether to do a Composite Restoration (Sandwich Technique) or a Root canal.
Next Steps
Please visit the dentist nd get the necessary treatment. Do not delay. it might get worse. it might even cause swelling.
Health Tips
Do not eat anything hot/cold, Sour/Sweet nd Hard from that side.
