Tooth and Mouth Problems

Noticed from few days while brushing my teeth blood comes out from it. Not exactly from where but blood comes out from mouth. There is no pain currently. Worried is it serious or not.

I wish to get veneers for three of my front teeth. I would like to know how much it would cost me and what will be the procedure.

I were to get the RCT done but lockdown happened. It pained once but I took enzoflam for 3 days and since then it has been fine. The tooth is little sensitive at times but no pain. I am conscious of loosing the tooth as it has become hollow. I stay in Pune and I am scared of going out for a procedure. Please advise what can I do. Attached are pictures of current state of tooth.
