No dentist licensed under the provisions of this chapter or members of the same profession licensed to practice in other states of the United States, who voluntarily and gratuitously and other than in the ordinary course of his or her employment or practice, renders emergency medical assistance to a person in need of assistance, is liable for civil damages for any personal injuries that result from acts or omissions by those persons in rendering the emergency care that constitute ordinary negligence. The immunity granted by this section does not apply to acts or omissions constituting gross, willful, or wanton negligence, or when the medical assistance is rendered at any hospital, dentist’s office, or clinic where the services are normally rendered.
