Hello!
It depends on the length of the remaining tooth, whether it can rebuilt or not, otherwise, we can do root canal of the broken tooth, put a post and build a crown over it. It will cost from Rs. 2000 if it is normal build up and with everything including the cost can go upto Rs. 10,000 - 12,000.
Next Steps
Go for an X-Ray and see weather pulp is damaged or not.
Health Tips
Do not bite from the fractured tooth.
