I think you guys are seriously underestimating Bruce's resourcefulness.
I believe that Mr. Condello is standing with the worlds first "Auto-Dentist", which Bruce has developed to allow him to continue to generate a decent living while devoting 100% of his time to his true passion.
I base this on several specific features.
First, note the pleasant but rather blank expression. Certainly Bruce's patients will recognize this as his familiar "I'd rather be at my pond" look.
Second, the attire. Classic for the "Master of My Own Domain" casual professional.
Note also the gloves. I suspect this proprietary device has yet to be patented, so he doesn't want to give anything away.
