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.

San Francisco dentist treats snoring and obstructive sleep apnea

San Francisco dentist treats snoring and obstructive sleep apnea

A common but serious sleep related breathing disorder frequently goes undiagnosed because many people dismiss it as harmless snoring. Obstructive sleep apnea involves a halt in airflow while sleeping despite ongoing efforts to breathe. These episodes occur when the sleeping person’s muscles relax, allowing soft tissues to block the airway. Most people who have obstructive sleep apnea snore frequently and loudly, with silent pauses of 10 seconds or longer, which is followed by gasping, snorting, or choking sounds as they resume breathing.

Effects of Obstructive sleep apnea

  • Oxygen levels fluctuate
  • Heart rate increases
  • Daytime blood pressure is chronically elevated
  • Increased death rate due to cardiovascular conditions
  • Impaired insulin resistance and glucose tolerance
  • Reduced ability to concentrate or focus
  • Elevated risk of accidents while operating machinery

Risk groups

  • Those who are overweight or obese
  • Men with a neck 17 inches or larger and women with a neck 16 inches or larger
  • Post-menopausal women and middle-aged or older men
  • Ethnic minorities
  • People who have bony or soft tissue abnormalities in the head or neck
  • Heredity – other family members have obstructive sleep apnea
  • Smokers
  • Hypothyroidism
  • People who suffer from nighttime nasal congestion due to rhinitis

About 80 percent of adults with obstructive sleep apnea remain undiagnosed. It is important that those in the high-risk groups remain especially vigilant for signs of this condition. Anyone exhibiting symptoms of obstructive sleep apnea should visit a physician for an accurate diagnosis through a sleep study.


Although some nasal sprays and internal or external nasal dilators may reduce snoring, no evidence suggests they help relieve obstructive sleep apnea. Losing weight, avoiding alcohol, stopping smoking, changing sleeping positions, and elevating the head are some behavioral changes that may help reduce symptoms. A device that provides continuous positive airway pressure via pressurized air through a mask worn while sleeping is the standard treatment for sleep apnea. However, many patients complain of discomfort and fail to comply with this treatment.

A simple, comfortable oral appliance is an effective treatment for mild to moderate sleep apnea. These devices work by stabilizing or repositioning the jaw or tongue.

Dr. Leo Arellano is specially trained in dental sleep medicine and he can help people in San Francisco and across the Bay Area find relief from sleep apnea. Call 415-881-4343 to schedule an appointment today.
