You are eligible to apply though you will require a higher IELTS band. A 6.5 and above is required for Masters degree applicants. Visit the university websites for specific requirements though. If an university requires a 6.5 they will not consider anything below 6 considering the stringent admission procedures. If you are aiming for the TU universities consider taking the GRE. Visit the daad website for university specific information.

You need to get admission in a university, not college. Check out the link mentioned below:

If you want to live there and work there after your study and want to make connections then my suggestion is to learn at least German A2 level from Goethe. It will also help you to get
admission there. After you get admission, you will be offered to learn German language in your semesters without any fees.
All the best.
Note: Always opt for Goethe institute to learn German language as the embassy only recognize its certificate.

It is not free Aratrika.
Dentistry programs in these countries take up to 6 years for completion. In Germany, they are not split into Bachelors and Masters degrees. Students must clear the State Examination (Staatsexamen) after course completion. So there is no point looking for MDS courses in Germany unless you want to start afresh. This is the same in case of France too however there are exceptions offering post graduate studies. So, please write to the universities for specific requirements.
