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.

Good oral hygiene is vital to the prevention of periodontal (gum) disease

Gum Disease of San Francisco dentist


It is important to brush your teeth twice daily for at least two minutes each time. Use a small head toothbrush with soft, round tip bristles. It is important to brush every surface of every tooth, so choose a system that is easy to remember. For example, you may start brushing at the back tooth on the left side of the upper arch, working around to the right cleaning each surface of each tooth carefully. Repeat the procedure with the bottom arch, making sure to remember the back surface of the very back teeth. This method ensures that no teeth will be missed. Hold the toothbrush at a 45-degree angle to the teeth with the edge of the bristles directed toward the gumline and brush in small gentle strokes. Make sure to “sweep” the loosened debris away from the gumline so it can be rinsed out of the mouth. The toothbrush should be replaced every two to three months, as it can become a bacteria breeding ground. It should be replaced sooner than that if it becomes worn.


Flossing between teeth daily is critical to clean the areas that a brush cannot reach. If flossing is skipped, then 35% of the surfaces of the teeth have not been cleaned. There are a variety of dental flosses available. Avoid choosing very fine floss, as it can cut the gums. There are a number of flossing aids available. Very fine interdental brushes can be worked between natural teeth and around restorations effectively cleaning the surfaces. For those who have a dental bridge, a floss threader facilitates cleaning under the bridge. Oral irrigators, such as Waterpiks can be extremely helpful for those who wear braces.

Use good quality fluoride toothpaste that isn’t too abrasive. Many of the brands advertised for whitening are highly abrasive. A small amount, about the size of a pea is all that is needed. For small children a light smear of toothpaste is sufficient. The toothpaste may also contain triclosan, which is an antibacterial agent that may be helpful in reducing mild gingivitis.


Antimicrobial mouthwashes, such as Listerine, Periogard, or Peridex, may help reduce plaque, and therefore facilitate the prevention of gingivitis.

Dental Care

Maintaining regular dental checkups and professional cleanings by a hygienist is crucial to the prevention of periodontal disease. The hygienist can clean the areas that brushing and flossing cannot reach. Regular exams enable diagnosis and early treatment of any oral conditions that do arise.

Call 415-881-4343 and schedule an appointment with Dr. Leo Arellano for a comprehensive dental exam and cleaning today. It is the first step down the path to lifetime optimal oral health.

What our patients are saying...

We’ve gone to Dr Arellano for many years and have never been disappointed with any of the work he’s done. Recently my husband broke a tooth and Leo got him in and had the tooth repaired within a few short hours. Service like that is very hard to finds these days. His office staff is fantastic. Nice people you are always glad to see. I would highly recommend Dr Arellano to anyone who is searching for an honest, competent, well trained dentist.
