According to CBS Miami, John Collazos was arrested last week over the incident, which is said to have taken place in 2010.
A female patient reportedly complained to police when 47-year-old Collazos administered paste to soothe her toothache and, when it didn't work, injected her behind to reduce the pain, in the process kissing her buttocks and touching her genitalia.
Collazos was arrested two months ago in Davie, Florida for carrying out unlicensed dentistry in a warehouse. He is also said to have fitted a Hollywood apartment with dental equipment.
The suspect targeted immigrants for his allegedly dodgy dental services, claims WSVN.
Collazos has been charged with practising medicine without a licence and battery, with four victims identified.
