Welcome to our Periodontal Practice in Mission Viejo

Our Disinfecting Policies to Protect You During the Coronavirus Season

We have always made sterilization and disinfection of our office a priority. That in itself protects you from possible disease transmission during this outbreak as well as any viral season. Here are the policies that we have in place:

1. We are asking every patient to wash his or her hands in our presence in the treatment room. That is for at least 20 seconds using soap and water.

2. Our staff and doctors wash their hands in the presence of the patient at the beginning of every visit.

3. We are cleaning our instruments in two areas after treatment. One is by the assistants in the treatment room. The second is by our sterilization assistant in the sterilization room. That is done under 2.5X magnification.

4. We are disinfecting all common areas such as door handles, knobs, public surfaces both in the treatment rooms and the reception room and front desk area, bathroom faucets, toilet handles, seats, etc. on a frequent basis throughout the day.

5. We use new masks and gloves for every patient.

6. We cover all surfaces, hoses, and electronics with plastic wrap. The plastic wrap is changed between patients.

7. We encourage you as well as our staff to avoid touching our faces.

8. If you are ill, please reschedule your appointment with us. We are sending any patient or staff member home who has symptoms of illness.

We are happy to answer any questions regarding our disinfection and sterilization policies and look forward to making every visit to our office safe, comfortable, and effective.

Minimally Invasive Gum Recession Treatment

For patients with gum recession, we perform minimally invasive gum grafting procedures and restore your natural gum line. A restored gum line not only enhances the beauty of your smile, it preserves the health of your teeth by protecting them from damage and decay.

Our doctors use micro-surgical instrumentation and advanced gum grafting procedures. This makes the treatment much more comfortable and healing time much faster than with traditional methods.
