Simple, Clean, Professional, Attractive. I used element spheres to create a tooth. The element spheres represent the technological aspect, as well as the word "Element' in your business name. The tooth of course represents the dental industry. I used the Mauve and Teal to keep consistency with your existing colors, as well as make it a little more on the feminine side, as per your notes. This mark is 100% original. You can trademark.
this was a great first response, but we'd like to emphasize more the benefits to the patient and less a stylized tooth. we emphasize more sophisticated reconstructions, like full smile rehabilitation. i like what you did here, but i ranked it 3rd currently.
