Logo for new dental company

I need a logo for new dental business. It will be directed initially at dentists and then later to the public. The product is a new way to make dentures, for people with no teeth. **No toothbrushes or teeth or cartoons. No apples with bites out of them.** It will be for USA for now but going globally in 1-2 years. It must be professional, clean and not more than three colors, standard CMYK It must be a little conservative but appeal to the general population as well, mostly older people. Simple, clean, modern without being gimmicky. It must not go out of style in a few years but last for many years
