Our community has been through a lot due to the ongoing pandemic, and all of us are looking forward to resuming our normal habits and routines. While many things have changed, one thing has remained the same: our commitment to your health and safety.

Infection control has always been a top priority of our dental practice, and you may have seen that we take great pride in this. Our infection control processes are made so that when you receive care, it’s both safe and comfortable. We want to tell you about the infection control procedures we follow in our practice to keep the patients, staff, and the ones we come in contact with in our daily lives safe.

Our office follows infection control recommendations made by the American Dental Association (ADA), the U.S. Centers for Disease Control and Prevention (CDC), and the Occupational Safety and Health Administration (OSHA). We follow the activities of these agencies so that we are up-to-date on any new rulings or guidance that may be issued.

Upon the emergence of COVID-19, here are some additional measures we take to ensure your safety:
  • Our office will communicate with you beforehand to ask some screening questions. You’ll be asked those same questions again when you are in the office, and we will be taking your temperature. Based on your answers and if your temperature is 100.4°F or higher, we will need to reschedule your appointment.
  • We have hand sanitizer that we will ask you to use when you enter the office. You will also find some in other places in the office for you to use as needed.
  • You may see that our waiting room will no longer offer magazines, children’s toys and so forth, since those items are difficult to clean and disinfect. Similarly, please limit the personal belongings that you bring inside to your appointment.
  • Appointments will be managed to allow for social distancing between patients when possible. That might mean that you’re offered fewer options for scheduling your appointment. Please respect the social distancing requirement of 6 feet where practical.
  • We will do our best to allow greater time between patients to reduce waiting times for you, as well as to reduce the number of patients in the reception area at any one time. To that end, please consider calling from your car to check on the status of the reception area and be on time. Also, please come alone to your appointments. If needed, one guardian/caretaker is permitted, but they must remain in the reception area.
  • Please arrive with face masks/coverings for they will be required at all times for both patients and staff when appropriate.
  • An antiseptic mouth rinse will be used just prior to treatment for the health and safety of all. Where possible, expect changes in how we do certain procedures to eliminate or reduce the spread of aerosols and splatter during treatment. For example, for now we will be temporarily eliminating ultrasonic tools and teeth polishing during your teeth cleaning appointments until further notice.
  • Clear sneeze guard barriers between you and our front desk personnel will be used to aid in social distancing, and we ask that we all limit our conversations to what’s necessary to limit contact time. More regular and frequent sanitizing of high touch areas and items will be done for your health and safety. This includes door and other handles, light switches, countertops, etc.
We look forward to seeing you again and are happy to answer any questions you may have about the steps we take to keep you, and every patient, safe in our practice. To make an appointment, please call our office at 415-752-8311 .

Thank you for being our patient. We value your trust and loyalty and look forward to welcoming back our patients, neighbors, and friends.

Options for tooth whitening in San Francisco

Dr. Leo Arellano at Leo Arellano DDS PC Explaining Teeth Whitening Options

People have appreciated the beauty of a brilliant white smile throughout history. Evidence has been found of primitive teeth whitening procedures used in ancient Greece and Rome thousands of years ago. These ancient societies used ingredients such as wine or urine. Thankfully, modern science discovered the benefits of peroxide based bleaching formulas.

In today’s image conscious society, a beautiful white smile is valued more than ever. There are also more formulas and methods for whitening than ever. Over the counter products, such as toothpastes and mouth rinses, yield unsatisfactory, if any, results. Commercially available strips and trays are slightly more effective, though they are much weaker than professional strength formulas. There is also a significant risk of burning soft tissues or causing tooth sensitivity when treatment is not supervised by a dental professional.

In office bleaching procedures, or custom trays from a dentist, are considered superior in safety, speed, effectiveness, and lasting results. There are many brands of professional teeth whitening. Dr. Leo Arellano offers several options, selected for their exquisite results and high level of customer satisfaction. Each has unique advantages, and the best choice is different for every individual.


The unique formula of Opalescence includes fluoride and potassium nitrate, which improves the health, as well as appearance, of teeth. These ingredients strengthen the enamel, and help prevent decay. In-office Opalescence treatment takes about an hour, and does not require the use of lights.

A take home version of Opalescence whitening is also available. It is gentle and effective, containing potassium fluoride to minimize sensitivity. Three strengths are available to meet the individual needs of each patient.
