SAN FRANCISCO, CALIFORNIA- A recent survey states more than 75 percent of Americans suffer from some form of gum disease, ranging from mild gingivitis to severe periodontitis. Do you know if you’re at risk?

Dr. Robert Walley and our team of skilled hygienists here at our San Francisco dental practice are equipped to provide revolutionary OralDNA testing. This easy test exposes the bacteria that trigger gum disease so we can more effectively diagnose and treat you.

Periodontal disease is known as the silent disease because it doesn’t always exhibit symptoms a patient will notice until it reaches advanced stages. If undetected, patients eventually may experience painful swelling, bleeding and sensitivity. In some cases, tooth loss is inevitable. There’s a growing body of evidence that suggests advanced gum disease (periodontitis) contributes to cardiovascular disease, stroke, dementia and certain types of cancer.

With the information provided by OralDNA testing, Dr. Walley can thwart the progression of gum disease before such consequences become a reality.

What It Is

OralDNA saliva testing eliminates the guesswork by giving insight on the specific bacteria lurking around your gums. It’s an efficient and noninvasive way for us to determine your individual risk factors for gum disease. By knowing exactly what and how much periopathogenic bacteria exists in your mouth, we can more accurately diagnose you.

“An accurate diagnosis will accelerate treatment, since we know the specific bacteria that threaten your health,” says Dr. Walley. “OralDNA allows us to completely customize your periodontal care.”

There are 13 strains of periopathogenic bacteria known to trigger gum disease. OralDNA testing alerts us to their existence, which allows us to promptly address the issue and avoid the need for future extensive treatment. Bacteria associated with oral HPV can also be identified through this quick and simple test.

How It Works

Saliva diagnostics are convenient and fast. Here’s how the saliva sample is collected:

Patient swishes a saline solution

After 30 seconds, solution is spit into a funneled collection tube

The tube is sealed and sent to an OralDNA lab for DNA-PCR analysis

Email is sent to Dr. Walley when test results are available

OralDNA sends a detailed report to Dr. Walley of the high, moderate and low risk pathogens residing in your mouth. With this information, we can prescribe a treatment that’s perfectly suited to your immune system and periodontal health needs.

SAN FRANCISCO, CALIFORNIA- Pregnant women are bombarded with a list of rules and restrictions. Don’t do this, don’t eat that, and certainly don’t go to the dentist…right?


October is National Dental Hygiene Month, and Dr. Robert Walley is using the occasion to emphasize the necessity of professional dental care for expectant mothers.

“There seems to be this notion that expectant mothers should stay away from the dentist,” says Dr. Walley. “In reality, the opposite is true.”

Thanks to surging levels of the progesterone hormone during pregnancy, moms-to-be often experience what’s known as “pregnancy gingivitis.” This form of gum disease triggers swelling, bleeding and sensitivity in the gums. It’s estimated that 50 percent to 70 percent of expecting women will suffer from gingivitis during their pregnancy.

Swollen and irritated gums are increasingly susceptible to infection. That’s bad news for anybody- especially a pregnant woman. The mouth is the gateway to the bloodstream and an ideal environment for bacteria growth, so it’s important to be proactive about dental health during this critical stage. 

The Journal of the American Dental Association contends that women with chronic gum disease are four to seven times more likely to deliver babies prematurely. Low birth weight has also been linked to gum disease during the gestation period. Although incredibly rare, cases of oral bacteria traveling through the bloodstream and harming the baby have been reported.

A proper at-home dental hygiene routine, which includes brushing with a soft-bristled toothbrush for two minutes twice daily, flossing and correct use of mouth rinse, plays a major role in preventing gum disease. However, only a professional is equipped with the knowledge, tools and expertise to ensure teeth and gums are thoroughly cleaned.

There is one element of truth to the old dental care misconception. Elective procedures such as teeth whitening should be postponed until after the baby is born. Pregnant women should not subject themselves to any unnecessary chemicals, medicines or discomfort prior to delivery. 

Celebrate National Dental Hygiene Month by taking steps to achieve a healthy smile. Dr. Walley encourages pregnant patients to visit our office for a close examination and professional cleaning. In collaboration with our skilled dental hygienists, Dr. Walley will ensure teeth and gums are healthy and thriving. It’s one small step that can make a big difference in the health of mother and child.
