Restorative Dentistry deals with the branch of dental science that is responsible for filings, crowns and implants. This is a bit different from the other dentist jobs, where you are supposed to help your patients get better from tooth aches. Here, the patients will have teeth conditions that are severely sore and that requires a prosthetic help to bring back the original conditions of the tooth. For that reason, you need to have knowledge of the latest implant technologies. You must know about the cost-effective technologies available in India, as a lot of people coming to the dentists here cannot afford such high costs of surgeries. You will be able to learn about such numerous technologies in this course, both incurring high or low costs on the patients. One of the popular colleges offering this certificate course is Sikkim Manipal college of Dental Sciences. This is generally a one year professional course. Some colleges offer this course online, while some others offer this as regular but part time course. Choose the course according to your suitability.
