Don’t get me started on Mouth Mechanics. My wife had to see 1 dentist and 2 oral surgeons to finally determine she needed an implant. All the dentist could do was drill and fill. The first oral surgeon said he did root canals but not extractions. The second could do the extraction and implant base, but the dentist had to set the implant. Each dentist/oral surgeon needed new x-rays. Apparently, they could not share pics. Scammers! My dad always said that dentistry could be completed with a 1 year correspondence course.
The flip side is that dentistry is now good at treating and repairing actual cavities and other issues. Soon, special mouthwashes will become widely available that implant and foster the growth of genetically modified bacteria that displace the acid generating species of bacteria that cause cavities and gum disease.
