A dentist is similar to a doctor. Unlike a doctor, a dentist is going to get far more non-urgent calls as patients will want to know when they can pick up various orders, as well as to book follow-up appointments. The key here is prioritizing so the dentist can respond promptly to the patients who need emergency dental work and other urgent consultations.
People have short attention spans these days, and you should always craft your communications for the lowest common denominator with something as universal as your voicemail.

For phone greetings to be successful, they need to be: Crisp. A crisp, clear voice goes a long way. The message needs to be clearer than glass. No shuffling papers or dogs barking in the background. **Professional. **Your phone greeting needs to sound like you're a real company, not a random person answering their cell phone. Thought-out.
Funny voicemail greetings are just that. These types of greetings have no rules whatsoever. They’re just for funsies, so make those you care for the laugh. Most of the time, they are personal, but certain businesses can use them as well. Perhaps you operate a theatrical costume company that specializes in clown memorabilia, or perhaps you run a business that sells pranks, such as plastic puppy poo, and whoopee cushions.
