Its just like someone asking the price of a computer. There are so many types and a clinical examination is required to choose something that meets your requirement. Rct in childhood might not be rct. An xray is mandatory

Hi dear, felt very sorry for your broken front tooth. And thanks to you for saving your natural tooth by doing a root canal treatment. Now you are only concern whether the cap will affect your daily eating or not?? Rather you should be more concerned, as this is front tooth  which adds value to your face and personality. And more over you are in your youth age and a software engineer by profession, so you should have the best quality of cap rather than going for the cost effective one just for the sake of the cap. And very sorry to say that, this is not a forum to discuss the cost as it varies depending on the quality of the material, sterilisation of the clinic and the services and the follow up service you get from the clinic. You deserve the best quality cap. And to your knowledge, that cap won't affect your daily eating if done properly. Thank you

Starts from Rs.1000/ tooth

Please consult dentist first with proper X-ray and clinical examination Since it's your front tooth it will need careful esthetic and functional planning
