Your Safety is Our Highest Priority

Study Finds Dental Offices Among Safest, Most Essential Businesses Amid COVID-19 Pandemic

Fast Company (6/15, Cohen)

Here at Providence Prosthodontics Dental Group we care deeply about each of you and have worked diligently to ensure that our office and staff have been properly outfitted and trained so that you and your family will remain safe when visiting our office. Under the guidance of the California Department of Public Health, a letter to California Dental Healthcare Personnel was delivered on May 7th, 2020. The letter provided guidance for resuming deferred and preventive dental care. Although we have always met or exceeded guidelines published by OSHA and the CDC the new guidelines have required that we adopt newer standards for the prevention of transmissible disease. 

We have procured Personal Protective Equipment (PPE) including N95 masks, surgical scrubs, disposable paper gowns, and have installed physical barriers for your safety. Additionally, we further trained our staff on the standardized use of this equipment including the use of sanitization fogger protocols that add an additional layer of cleanliness and security.

Again, your health and well-being continue to be our highest priority. The measures we will be taking to provide a safe dental treatment experience include, but are not limited to, the following:

Upon Your Arrival at the Office

  • Patients and staff will be screened while entering the office. Temperatures will be checked. Any patients or staff showing signs of a fever or other symptoms of illness will be asked to reschedule their appointment.
  • Only patients will be allowed entry into the office unless an accompanying companion is required. Accompanying members not required for assistance will be asked to wait outside whenever possible to help maintain social distancing.
  •  Patients are asked to wait outside the office until their scheduled appointment time.
  • The reception area chairs will be spaced apart to allow for 6 feet of distancing. 
  • We will ask that you continue to practice social distancing measures in common areas of the office, including the front desk.
  • The doors between the waiting area and treatment rooms will be propped open all day.
  • Masks are required to be worn at all times in the office except for treatment.
  • We have hand sanitizer stations throughout our office.

During Treatment

  • All rooms will be entirely sanitized before and after each patient is seated, and public areas will be cleaned frequently throughout the day.
  • All treatment rooms have high-volume air filtration and air purification units. The units can remove particles smaller than COVID-19 viruses.
  • The office will be treated each day with an atomizer fogger which administers hypochlorous acid to disinfect office surfaces.
  •  Our team will continue to follow guidelines set forth by the American Dental Association (ADA), California Dental Association (CDA), CDC and OSHA regarding personal protective equipment (PPE) and office sterilization.
  • Our staff will be wearing masks, full garments and dedicated shoes which are sanitized and laundered daily. 
  • During patient care requiring generation of aerosols our clinical staff will be wearing N95 masks, goggles, face shields, gloves and full garments which are disposable, changed, or sanitized.
  • All surfaces that met the patient will be wiped with disinfectant including the patient chair and the accessory chair where the patient placed their personal items and/or coat hanger.
  • We will place instruments after each use into an autoclave (a high-pressure steam oven) to kill infectious organism, including coronavirus.
  • We will wash our hands thoroughly and apply antibacterial disinfectant between each patient.

In addition to these standard measures, we will be exercising a higher than normal level of infection-control and social distancing for the foreseeable future. While we adore and value each of our patients, handshakes and hugs are no longer appropriate and may be replaced with a bow, wave, or possibly an “elbow bump” for the time being.

While we are doing everything in our power to protect you, we also ask for your cooperation in making our office environment a safe one when you visit us. If you have a cough, fever, or chills, please call our office to discuss when you should reschedule. We will be checking temperatures on all patients as they enter the office and anyone with a reading over 99.9 degrees will be asked to reschedule at least three weeks later as a precaution. 

Should you wish to discuss your future dental care or have any questions about treatment and whether you should schedule an appointment, please do not hesitate to call us at 714-771-7555. We will provide personalized conversations regarding your individual dental needs and will review with you in detail our infectious disease/COVID 19 control procedures.

COVID-19 Update

Covid-19 update 

March 25, 2020

Dear Patients and Friends of Providence Dental Group. 

We hope this finds you healthy, happy and safe. This is an update of our activities in response to the Covid-19 concerns. We appreciate that this is the time of uncertainty and anxiousness for everybody. There is no precedent in history that we can use as a model to predict our future. We hope you’re staying indoors and remain safe. 

There is good news that the Senate today approved a $2 trillion dollar emergency relief package that should benefit hospitals, individuals, and small business.

Governor Newsome’s California quarantine will likely be extended until April 6th. As you may know we closed operations March 16 with the intention of starting back March 30. Now we are looking at retuning April 6th but it might be April 13th. We will not open our offices for patient care, other than for critical emergencies, until we are certain that our patients and staff are totally protected in a safe environment. 

Rest assured we are here for you should you have an emergency. Our doctors are on call 24 hour/ 7 day a week and can be reached through the answering service at (714) 771-7555. In regards to starting operations back up, we are committed to your safety and health. 

-We will take patient’s temperatures prior to treatment and screen for travel, symptoms, or exposure prior to scheduling.

-We will not see patients without proper PPE’s for everyone in direct patient care. As you are aware these may not be available for quite some time until the hospital shortage is alleviated. That has the obvious priority. This will be the principle factor determining our return to safely providing patient care.

-We continue to monitor the Center of Disease Control and California Dental Association guidelines as they are changing frequently.

-Upon return we will continue to use universal standard precautions and will sterilize all instruments, and cover disinfect all room surfaces between visits.

At this point in time it is premature to plan exact dates of a return. You will receive text, email, or call to cancel or reschedule if you have an appointment prior to April 6th. We are looking forward to resuming normal activities as soon as possible.

We are committed to your personal safety and health and hope you are practicing social distancing. Remember that transmission of the Coronavirus requires human interaction with a person or infected surface. Wash your hands and don’t touch surfaces. Remember, unless you have been tested and are told that you are negative for the virus, you can’t presume you don’t have it. Not all people who have contracted Coronavirus experience symptoms. In fact, many who do show symptoms don’t exhibit them for days after being exposed and are unknowingly contagious.

Yes, these are trying times and we hope that you and your families all get through these times.

Our warmest regards and concerns,

David Guichet DDS

Prevention is your best investment!

Regular dental checkups allow you and your dentist to stay ahead of dental problems, like tooth decay, periodontal (gum) disease and even oral cancer. The earlier your dentist diagnoses a problem the easier and less expensive it is to treat.

A professional dental cleaning is essential! As it is the only way to effectively remove tartar (hardened plaque). Tartar contains cavity-causing bacteria.  Although, brushing and flossing regularly is mandatory to maintain a healthy smile, it is not sufficient alone. Tartar grips to your teeth and requires a professional to remove it.

Perhaps one of the most important reasons to invest in regular dental exams and cleanings is that it has a positive impact on your overall health. Recent studies have shown that there’s a link between periodontal disease and heart disease; when the former is present, the latter is twice as likely.

According to the American Academy of Periodontology, gum disease can have a domino effect on your health. The bacteria caused by periodontal disease can enter your bloodstream and attach to your heart’s blood vessels, causing them to swell. Inflammation, or swelling leads to atherosclerosis or hardening of the arteries and places you at a greater risk of blood clots, heart attack and stroke.

Regular checkups and cleanings are not only preventative, they are an investment in your health and well-being.

And that’s priceless…

Dr. Guichet speaks on Digital Dentistry at World Summit Tour 2017

This summer Dr. David Guichet from Providence Prosthodontics spoke about Digital Dentistry at the World Summit Tour 2017 in San Diego to the worlds leading dental professionals. The World Summit Tour is a dynamic, scientific congress on the latest in state of the art dentistry focusing on dental implantation. On The World Summit Tour, dental professionals share with their colleagues the latest innovations and scientific knowledge in dentistry as well as inspiration and passion for the field.









As a leader in his field, Dr. Guichet was asked to speak about innovations in Digital Dentistry and it’s future. His commitment to education and understanding of groundbreaking innovation in implant dentistry inspired his platform.









Digital Dentistry refers to a large scope of dental technology that uses computer-controlled devices rather than mechanical. For implant dentistry, this can include the design and creation of surgical guides, digital radiography, laser dentistry, digital x-rays and much more. It can provide improved proficiency and accuracy as well as give more definitive outcomes.









As scientific research progresses, digital dentistry will only rapidly expand in its use in dental offices everywhere making Dr. Guichet’s presentation extremely vital and informational for the dental community.

If you have any questions about digital dentistry and how it can be utilized in your next dental procedure, please contact Providence Prosthodontics Dental Group for more information at (714) 771-7555.

What are the Main Causes of Teeth Grinding

Most people occasionally clench or grind their teeth (medically known as Bruxism) due to stress, but extensive teeth grinding or clenching can have major effects on your dental health.


But what causes a pattern of teeth grinding?




The number one cause of teeth grinding is severe stress and anxiety. When dealing with high stress, people tend to clench their jaws or grind their teeth without realizing it as a way of coping. This commonly occurs while driving in a precarious situation, or similar situations. People with this issue tend to experience stress during sleep also so they end up putting their jaw muscles in an over-active mode of mastication.


Medical Conditions and Medications


Teeth grinding can also be a side-effect of certain medications. It is most common among someone who uses antidepressants, antipsychotic and psychotic drugs. If you find yourself having this issue, ask your doctor about what your options are before you cause irreversible damage to your teeth.


Issues with Sleep


If you have any sleep issues or sleep disorders, it can be related to teeth grinding also. Someone who doesn’t sleep well can become more prone to developing this habit.




Excessive smoking, drinking a lot of caffeinated drinks, alcoholism, and the use of recreational drugs can also create a habit of teeth grinding or clenching.

Bite Misalignment and Malocclusion


When a person loses a tooth or few of them, some changes occur in the bite and mouth. Other teeth migrate toward this empty space in the mouth and causes bite misalignments. Because of that, joints of the jaw loses its control of the movements and it is believed that it causes teeth grinding. Or the constant moving of your jaw, as your tongue feels the new changes can mimic teeth grinding and cause dental health issues such as an inflamed jaw.


Other Medical Conditions


If you suffer from Dementia, Parkinson Syndrome, Mental Diseases, Epilepsy, Sleep Apnea, Gastroesophageal Reflux Disorder or Attention-Deficit Hyperactivity Disorder, there is a high possibility that you will suffer from teeth grinding also.

If Bruxism is left untreated


With time, if the teeth grinding is left untreated, it can result in tooth loss, teeth loosening, and fracturing. You will also experience pain or inflammation. Teeth can also wear down and lose their vertical height, so you might require additional restorations like dentures, crowns, bridges or dental implants. Moreover, it can cause TMJ/TMD. In that case, some changes in your face might appear also. What is more, it is not unusual that you will experience severe jaw and facial pain and have tension-type headaches.


Getting to know the root of the problem allows you to get better results in eliminating the problem. Visit us at Providence Prosthodontics Dental Group to get your consultation with our highly-qualified specialists, who will help you to get rid of this teeth-damaging habit using various methods and techniques. Call us: (714) 759-2169.
