I believe for a long time already, that for any serious medical question it's better to hear at least 3 doctors. Visited several dentists recently, all gave me different diagnosis and recommendations. My mother also visited four dentists recently, all gave her different recommendations. When I say different, there is overlap between them. But also a significant difference. That's not only dentists. I have several examples in my family when non-dentist doctors give directly opposite opinions. Also a well known fact: surgeons always recommend to cut.
