Two employees of a Bryn Mawr dental practice have been charged with masquerading as a dentist and her assistant while performing cut-rate procedures in the office after hours.

According to the Montgomery County District Attorney's Office, the women - a receptionist and a dental assistant - pulled teeth, took X-rays, applied braces and crowns, and dispensed medications.

Cheryl Laing and Jessica Gullickson, both of Broomall, have been charged with running a corrupt organization, criminal conspiracy, multiple counts of theft by deception, unauthorized practice of dentistry, and recklessly endangering another person, according to the District Attorney's Office.

The women worked at the Smilz 4 Life dental office on Old Lancaster Avenue, which is owned by a licensed dentist, according to officials. Prosecutors said the employer was unaware of the illegal activities and has cooperated with investigators.

After hours, Laing, a dental assistant, allegedly played the role of a dentist while Gullickson, a receptionist, served as her assistant. According to prosecutors, they performed a variety of procedures on uninsured patients who were attracted by word of mouth. Laing claimed she could perform virtually all procedures for reduced costs, authorities said.

In one case, according to the District Attorney's Office, a patient reported that while undergoing root-canal treatment, Laing left the room and told Gullickson to "find the root." Another patient said he was in "excruciating pain" when it took Laing 45 minutes to pull a tooth.

The two accepted only cash and did not keep any records, take any medical or dental histories, or ask about drug allergies.

Investigators interviewed three patients but believe there may be dozens more. They are asking anyone with information to contact detective John Mick of the Lower Merion Township police at 610-645-6229.
