The cost ceramic or any cap, depends on lab, and the dentist
. Nowadays, with advancement of technology in dentistry, some lab provide CAD CAM crown/ cap, which are precise and much better than conventional one. The cost of CADCAM cap more than conventional one. You can go for that as they come with warranty period. Again as I said cost of cap still depend on dentist lab and city. It better you visit your dentist. Thank you.
