Hi, 

You can opt for BDS (Bachelor of Dental Surgery) course if you cannot do MBBS.

As a student of BDS, you will receive training and education related to prevention, diagnosis and treatment of all diseases, malformations and injuries related to the mouth and its components. A person with a BDS degree can practice dentistry. After completion of the degree, many opt to join a government hospital to get hands-on experience. 

You can find more information regarding BDS Course on the following link.
