You can search for the dentist in your vicinity using Practo. There is no fixed cost for any treatment, whether it is root canal treatment or crown. The cost of treatment for RCT varies according to the experience of the dentist as well as the materials and techniques used. This can range from 1500 to 8000 rupees. Similarly there are different caps ranging from the least priced metal caps to the best Zirconia caps. Their price can also very from 1000 to 25000 rupees. I have my practice in Sector 9 Faridabad. You can contact me if you wish. Regards.
