According to authorities, the owner of the convenience store, Maria Magdalena Guaman-Castro, rented a room in the back of the store to Juan Hermida Munoz, where he provided dental services, including tooth extractions, anesthetics and cleanings -- all without a license.

Munoz, 64, is facing charges for unauthorized practice of​ dentistry and unauthorized practice of​ medicine.

"This practice puts the lives of patients in danger by unsanctioned and unsanitary conditions in receiving medical treatments," Milford police said in a statement.

Authorities say they also charged Guaman-Castro with conspiracy for renting the room to Muñoz.

An employee at the store tells NBC10 Boston that Munoz has been a longtime dentist in Ecuador where he also teaches at a university. He says Munoz was only trying to help people in the community who needed it.
