Dear Smiles4OC patients,

Dentists in California have been asked by the California Dental Association to voluntarily suspend nonessential or non-urgent dental care until further notice.

CDA does not make this request lightly and it is being done out of an abundance of caution during this historic public health emergency. At Smiles4OC we have decided to comply with this request to do our part in "flattening the curve” in order to follow sound, scientific public health advice to help limit infections and slow the spread of the virus. CDA also believes that by taking these extraordinary precautions dentists can make a difference in helping to preserve the limited supply of personal protective equipment critical for emergency dental care and frontline health care of personnel responding to the pandemic.

We are uncertain as to when we will be back to work. We are available for emergencies. Patients can call 714-557-0700 or email with any questions or concerns. We are confident we have a very safe environment to treat our patients. However, you must call first as walk-ins will not be seen without an appointment.

Please practice safety, take care of yourselves and your family. And let us know how we can help.

Dr. Rolfes and the Smiles4OC Team
