Hi,
Thank you for your query.
The X ray shows a previous restoration on the tooth which is marked. Even attempting to redo the filling will lead to pulpal exposure, so this tooth (46) has to be treated with root canal followed by a crown.
Alternatively, You can visit Oralia Dental Clinics, Sahakar Nagar for a consult with our specialist endodontist.
Next Steps
Being Proactive here helps a lot. Kindly visit your dentist and complete the RCT and Crown.
