Nip did a 5-10-minute exam and told me I had "serious" gum disease and needed several hundreds of dollars worth of work. I consulted two other dentists for their opinions, my former primary care dentist and a periodontist. Both said my gums were fine, there was no disease, and all I needed was a good cleaning. I never returned to Nip. He is completely untrustworthy. He talked more about money than about dental care. Beware!
