Answering your questions in the order ,
1. You have mentioned that you want to get the teeth removed , firstly i would suggest you visit your dentist after the lockdown and get an xray done of the 2 teeth , if they can be treated with a root canal then please go ahead with that option as that is not very invasive and also will be a more reasonable option in terms of money . A root canal will cost you between 3-5 thousand rupees and a crown on top of it will be approximately for 3000₹ for a metal and 45000₹ for a tooth coloured with metal inside ie a PFM crown . This treatment duration will be for 2 weeks approximately maybe even less then that depending on your infection and involvement of the decay on the tooth .
2. Secondly if your teeth cannot be saved and doing an extraction is the only option left then extraction will be done of the 2 teeth followed by an implant placement ( Please understand that in your case as this is the last teeth a fixed bridge option is not viable for you and only option of replacing this is with an implant or a removable denture . ) Im taking for granted that you are aware of this and have been advised an implant after discussion . An implant will cost you ₹30000- ₹45000 depending on your bone condition and system you and your doctor choose . An implant once placed integrates and becomes a part of your bone , after 3 months approx a tooth can be fixed on top of the implant . The total treatment duration of this will be a minimum of 3 months .
3. A good dental hospital around you- please go through your practo app of the clinics or hospitals near you. See the reviews and visit . Another way of choosing a dental practice is ask your friends and family for the their reference .
