You should go for RCT of the tooth, and get a crown. Since it is an anterior tooth, I would suggest you to opt for an E-Max crown, as it has the best aesthetics. An RCT will cost around 2k-5k, while the crown will cost around 6k-8k (depending on your dentist)

Consult an Endodontist
Health Tips
Do not linger the treatment. If you cannot afford the E-Max crown, you can still get a normal Ceramic crown, which will cost around 2k-3k
