McKnight & Weaver Dentistry will donate $100 from each case of teeth whitening started in October to Breastcancer.org, a nonprofit organization dedicated to raising breast cancer awareness. Appointments for whitening are required. New patients will need a comprehensive exam and X-rays prior to whitening. The office is at 1869 North Paris Ave. in Port Royal.
