Separate Dentists and Dental Labs. I only want dentists not labs.#43

I am not sure why these two businesses are connected. Can you please give me a way to separate to get just dentists? Also would it be possible to segregate the dentists into specialties, such as “general dentist” “cosmetic dentist” “orthodontist” “periodontist” “endodontist” “pediatric dentist” etc.?
