What Our Patients Say

Dr.John Mobilia and his staff are always very nice and helpful. I needed root canal for pain in tooth and they got me scheduled very quickly and took excellent care of me. Shout out to Dr. Ng she is great at implants and root canals. I experienced no pain even from the initial shot to numb. Thank you to all the staff in office and dental assists. I highly recommend them. I have been going to them for years!

There are Always Questions; and We Got The Answers

Welcome to our Frequently Asked Questions (FAQs) section, designed to address common queries and provide helpful information about Rancho Bernardo Cosmetic & Family Dentistry. If you have additional questions or need further clarification, feel free to reach out to our friendly team.

Which type of toothbrush should I use?

The brand of the toothbrush is not as critical as the type of bristle and the size of the head. A soft toothbrush with a small head is recommended because medium and hard brushes tend to cause irritation and contribute to recession of the gums, and a small head allows you to get around each tooth more completely and is less likely to injure your gums. It's unnecessary to "scrub" the teeth as long as you are brushing at least twice a day and visiting your dentist at least twice a year for cleanings.

Which toothpaste to use from any with Fluoride?

Your dentist or Hygienists are best educated to diagnose gum disease,  enamel erosion or sensitivity and make a recommendation as to which toothpaste is best for you.

How often should I floss?

Flossing of the teeth once per day helps to prevent cavities from forming between the teeth where your toothbrush can't reach. Flossing also helps to keep your gums healthy.

What's the difference between a "crown" and a "cap"?

These are restorations to repair a severely broken tooth by covering all or most of the tooth after removing old fillings, fractured tooth structure, and all decay. The restoration material is made of gold, porcelain, composites, or even stainless steel. Dentists refer to all of these restorations as "crowns". However, patients often refer to the tooth-colored ones as "caps" and the gold or stainless steel ones as "crowns".

What's the difference between a "bridge" and a "partial denture"?

Both bridges and partial dentures replace missing teeth. A bridge is permanently attached to abutment teeth or, in some cases, implants. A partial denture is attached by clasps to the teeth and is easily removed by the patient. Patients are usually more satisfied with bridges than with partial dentures.

What about "silver" fillings versus "white" fillings?

Although the U.S. Public Health Service issued a report in 1993 stating there is no health reason not to use amalgam (silver fillings), more patients today are requesting "white" or tooth-colored composite fillings. We also prefer tooth-colored fillings because they "bond" to the tooth structure and therefore help strengthen a tooth weakened by decay. While fillings are also usually less sensitive to temperature, and they also look better. However, "white" fillings cannot be used in every situation, and if a tooth is very badly broken-down, a crown will usually be necessary and provide better overall satisfaction for the patient.

Do I need to have a root canal just because I have to have a crown?

No. While most teeth which have had root canal treatments do need crowns to strengthen the teeth and to return the teeth to normal form and function, not every tooth needing a crown also needs to have a root canal. 

What forms of payment do we accept?

We accept all PPO's, Dental -Cal active duty and all major credit cards. We honor discounts for cash patients. 

Please call us at 858-385-1838 for all of your payment inquiries.

Dr. John Mobilia, DMD 

Dr John, with over 30 years of experience. I went to the University of San Diego (USD) and received a bachelor's in chemistry. I earned my DMD graduating in the top 10% of my class from Boston University. I then continued on to a residency program in advanced education in general dentistry (AEDG) earning a certificate of advanced Dentistry (CAGS). I joined the Navy a year after finishing my residency. My Advanced degrees placed me in positions of higher responsibility and Leadership. After my honorable discharge , I practiced in the private sector in Tierrasanta for 13 years. Primarily caring to Navy families and their children.

 I then opened my own practice 13 years ago in Rancho Bernardo acquiring the most modern equipment available, while retaining that small town sense of individual attention, that seems to be lost in the corporate dental offices.
