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.

Daly City obstructive sleep apnea sufferers can turn to their dentist for relief

Daly City obstructive sleep apnea sufferers can turn to their dentist for relief

Millions of Americans suffer from a serious, potentially life-threatening condition known as obstructive sleep apnea (OSA). It is characterized by episodes during which breathing stops entirely for 10 seconds or longer when a person is sleeping. These episodes can occur from 30 to hundreds of times per night. Many people in Daly City and across the nation are surprised to learn that their dentist may be able to provide comfortable, effective treatment for this disorder.

Signs of sleep apnea

  • Loud snoring that is interrupted repeatedly by pauses in breathing followed by gasping for breath or choking is the primary and most significant indicator of obstructive sleep apnea
  • General lethargy or fatigue
  • Daytime sleepiness, unintentionally dozing off during the day
  • Morning headaches, sore throat, or dry mouth
  • Irritability or depression and difficulty concentrating
  • High blood pressure

Although many people do not consider snoring as anything more than an annoyance, if it is accompanied by any of the above, it may be a sign of a serious condition. A medical professional should be consulted for an accurate diagnosis.

Potential complications arising from sleep apnea

Cardiovascular – The sudden drop in oxygen levels in the blood that occurs during an episode raises blood pressure each time it happens and puts stress on the cardiovascular system.

Medications – Narcotic analgesics and sedatives cause the upper airway to relax, which can make obstructive sleep apnea worse.

Surgery – After lying on their back while sedated, sleep apnea sufferers might have worse problems breathing and could be at an increased risk of post-surgical complications.

Eye problems – Some studies have found a link between sleep apnea and specific eye conditions, including glaucoma.


The most common treatment prescribed for obstructive sleep apnea is CPAP (continuous positive airway pressure), a device that keeps the airway open by delivering constant air through a mask. Although effective, patient compliance with this system is low due to discomfort and inconvenience.

Fortunately, many patients with mild to moderate obstructive sleep apnea can find relief through a comfortable, convenient dental appliance similar to a retainer that positions the jaw or tongue to keep the airway open.

Dr. Arellano and his team help many patients in Daly City and the surrounding areas sleep well at night with some suggestions for lifestyle changes and a simple oral appliance.
