There are multiple things that should be considered when looking for a great dentist for you and your family.
1. Look at Google reviews mainly: Make sure the dentist has more than 15-20 reviews and make sure the reviews are somehwhat recent (within 6 months to 1 year old)
2. Ask family, friends, and people in your local community: many times word of mouth can be a great way to determine reputation and legitimacy
3. Listen to your gut: Once you feel like you have done some research and feel confident about an office or place, make a consultation appointment and see how you feel after the consult
