Police released the arrest affidavit in the case of the Plano man accused of practicing dentistry without a license.
Officers arrested Jose Santiago Delao, 63, and confiscated all of his equipment that he used in his business Thursday morning.
An arrest affidavit details what the patient, who reported the home-based dentistry, claims happened to her.
The patient, whose identity has not been released, went to Delao’s home for a filling on Jan. 14.
The woman went to the home after receiving a business card at church. The business card offers an array of dental services including full and partial dentures.
She tried to leave the home because it did not look like a proper dentist’s office, according to the document.
The affidavit states "Delao would not let her leave, saying that she had already cost him time and money."
The latest news from around North Texas.
The affidavit continues to say that she was taken to a back room of the house and wound up in a dental chair. She received two injections, but when Delao started drilling, she started waiving her arms due to the pain.
Records say Delao "..pushed her hand back down and told her to stop complaining."
The document says the patient was still in so much pain eight days after her visit that she could not open her mouth.
"This guy has been operating probably for at least four years," Plano Police Officer David Tilley said.
Plano police worked with the Texas State Board of Dental Examiners, the state licensing agency for dentists, to confirm that Delao does not have a license to practice dentistry within the state.
Texas A&M Baylor College of Dentistry expert, Dean Hudson, said many aspects of the allegations are very egregious.
"I would be very concerned about not only the quality of care and any prescription drugs that he prescribed but also infection control and general patient safety,” Hudson said.
Hudson added that patients should never accept care unless proper licenses to practice and prescribe drugs are posted in dental offices, as required.
Dental schools offers discounted services and other lower cost options to help patients, Hudson said.
"We believe that most of his clients were uninsured," Tilley said.
Delao is still in Collin County Jail as of Friday evening. He is being held on $25,000 bond.
