Do you think Dentistry is saturated? No.... It isn't. Remember Henry Ford's words - A market never gets saturated with a good product, but very quickly with a bad product.
Ask me again....Is dentistry saturated? No...Dentistry is changing and changing for good, and faster than ever before. Opportunities are more than they were ever before. It's up to you to seize the opportunity and make the most of it. It depends on how big you think, rather than how conventional your thoughts are.
Will it ever get saturated?... Huh?...No... It was an imperfect world one thousand years ago and it will remain so even after thousand years from now. There will always be a need in all segments, creating opportunities for talented professionals.
