Mounting scientific evidence linking a bacterial pathway from the mouth to vital organs and body systems has physicians and dentists warning higher risk patients to ‘get their mouths cleaned up’.  

Gum Disease and Heart Disease
The American Heart Association claims that patients with poor oral hygiene resulting in chronic gum infections (or chronic bronchitis) have more than twice the risk of having a fatal heart attack or stroke than people without gum disease, as well as an increased risk of respiratory disease.

These claims are consistent with earlier reports  of a link between chronic infections and atherosclerosis (or thickening of the arteries).  Evidence is mounting that bacteria that cause periodontal disease may cause deposit of ‘plaques’ onto the inner lining of blood vessels.  These thickened areas on the inner walls of arteries cause further small blood clots to form that can contribute to clogged arteries and build up of fatty deposits within the heart arteries.

Gum Disease and Diabetes
Aside from an increased risk of stoke or hearth attack, chronic gum disease has also been interrelated with diabetes.  All the tell tales signs of chronic gum disease (increased bleeding of gums, bone loss around teeth, and increased pocketing around the teeth) may also be an indicator of the early signs of diabetes.  On the flip side, one of the related problems of diabetes is gum disease.  Uncontrolled or high levels of blood sugar can be damaging to the teeth and gums.  As a result, diabetic patients require more frequent professional care to make sure that their oral hygiene is maintained.  Increased frequency of dental visits and better home care are very important for diabetics.

Gum Disease and Low Birthweight Babies
Gum disease has now been shown to be a clinically significant risk factor for having premature or low birthweight babies. Mothers with periodontal disease may be at a 7 times greater risk for having a premature or low birthweight baby.  

Gum Disease and Smoking
Smoking and periodontal disease are linked as well. Smoking reduces the blood supply to the surrounding bone of the tooth. The intense heat and toxins produced during smoking can also affect the bacterial composition of the mouth and the body's immune response to periodontal bacteria. Smoking reduces the effect of periodontal therapy regardless of the level of oral hygiene.

Bottom line: Brush and floss. It could save your life!

Bad breath (halitosis), well known for its negative social connotations, is a condition that may also be a sign of poor health.    Ninety percent (90%) of halitosis originates in the mouth, caused primarily by the sulfur containing by-products left from the digestion of protein by the bacteria found in plaque.  These are some of the same bacteria associated with gingivitis and periodontitis,  with most of the halitosis causing bacteria mainly found on the tongue.  The remaining causes of bad breath originate from sources outside of the mouth, including the upper and lower respiratory tract, the stomach, and intestines.

The halitosis that originates in the mouth is primarily due to inadequate plaque control, periodontal disease, dry mouth, faulty restorations, and in particular due to excessive bacterial growth on the back surface of the tongue.

The management of halitosis may involve a combination of specific treatments to maintain plaque control, including the elimination of active periodontal disease, the correction of older dental restoration that are acting as food traps, and the routine cleaning of the surface of the tongue.  Oral rinsing with a mouthwash may be indicated in some instances, but without proper oral hygiene to control plaque buildup (brushing, flossing and tongue cleaning), this would only be a temporary measure.

April is Oral Health Month in Ontario, an important time to become aware of the link between your oral health and your overall health.  The Canadian Cancer Society estimates that 3,400 new cases of oral cancer were diagnosed in Canada in 2010. It is also estimated that 1,150 of those Canadians diagnosed in 2010 will die from the disease.

As oral health experts, dentists are uniquely qualified to help in the early detection of many medical conditions, including cancer.  Being trained in medicine, dentists are able to recognize the relationships between oral and overall health.  Since most people see their dentists regularly, they are often the first health-care professionals to have an opportunity to detect the many health conditions that affect your mouth.  Many patients are not aware of the extent that a dental exam can play in disease prevention.  Without an examination by a dentist, most early signs of oral cancer are difficult to detect.  If you notice a mouth sore or anything out of the ordinary that does not go away or heal after a couple of weeks, discuss it with your dentist.

Risk Factors for oral cancer include:

  • Smoking and chewing tobacco - particularly if combined with heavy alcohol consumption
  • Heavy alcohol consumption - particularly if combined with smoking
  • Excessive sun exposure - particularly to the lip
  • Age - people over the age of 40 have a higher risk of developing oral cancer
  • Gender - men are more susceptible than women to developing oral cancer.  In the past, men had a 6:1 ratio of incidence of oral cancer compared to women.  However, this ratio is narrowing and is now closer to a 2:1 ratio
  • HPV - more research is emerging that connects human papillomavirus infection - especially HPV-16 - with oral cancers
  • A diet low in fruits and vegetables - fruit and vegetables have a protective factor that is believed to reduce the risk for oral cancers.


  • See a dental professional for a regular dental exam
  • Quitting (or reducing) your tobacco and alcohol use lowers your risk of developing oral cancer
  • When you are outside and exposed to the sun, use lip balm with UV protection and wear a hat
  • Eat a healthy diet rich in fruits and vegetables
  • Brush and floss your teeth daily

The mouth has long been recognized as a mirror reflecting the health of the body.  With regular visits to your dentist and good oral health routines, you will have lots to smile about!:)



Researchers at King's College London, Brunel University, and London South Bank University have pioneered an invention that could remove one of the main factors in many cases of dental phobia- the noise of the drill!

The inventors have developed an innovative device which cancels out the noise of the dental drill, a development that could end the anxiety associated with many patients' fears associated with a trip to the dentist.  Its widely accepted in dental research circles that the sound of the drill is one of the prime causes of anxiety linked to dental treatment.  The device was developed in the hopes of eliminating this source of anxiety, thereby encouraging people to seek out the dental treatment they may require for optimal oral health.

The prototype, which now requires funding to take the development to market, works similarly to noise-cancelling headphones, but is specifically designed to deal with the very high pitched noise of the dental drill.


Talk about slick!....The Word Lens app by Quest Visual uses optical character recognition technology and makes converting text from another language as simple as pointing to the text and the application translates the text instantly!

Currently the application is only setup for English-to-Spanish and Spanish-to-English...the potential for this one is enormous:)

The teams of Drs. Joshi and Matheson of St. Laurent Dental Centre did there small part to help The Ottawa Mission by donating the fixings and time to help prepare over 400 sandwiches for some of the many homeless and poor of Ottawa that are served daily here.

The Ottawa Mission is a non-profit, faith-based ministry, meeting the needs of the homeless and those at risk of being homeless in the Ottawa region.

Established in 1906 on the foundation of food, clothing and shelter, the demand for The Ottawa Mission's services has increased dramatically in recent years. The Ottawa Mission's programs and services have evolved to meet the ever-changing face of homelessness in our city.

Love these modified 'Gelb' splints:)  Bite Tech (the manufacturer) has done a great job researching this product, and marketing their performance mouthwear to atheletes...stroke of genius!

Maclean's magazine reporting on the comments made by actor Michael Douglas during a David Letterman interview, that his type of throat cancer was due to a combination of alcohol and cigarettes.  Maclean's quoted Dr. Jonathan Irish, Chief of the Department of Surgical Oncology at the Princess Margaret Hospital:  "Smoking is by far the most important factor for oropharyngeal cancer, but alcohol alone increases the risk of this type of cancer, and smoking and alcohol together work synergistically." One of the leading theories about this "multiplier effect," says Irish, is that alcohol acts as a solvent, wearing away at the soft, mucosa-lined surface of the oral cavity, and increasing the ability of material-such as carcinogens in smoke-to flow into cells. Irish says, "The risk of a person developing cancer of the head and neck from alcohol alone is two to five times the rest of population, and smoking is 10 to 20 times. But you put the two together, the person will have about 40 times the risk of developing cancer."

A great interview by David Letterman with Michael Douglas, discussing his journey just after his first chemotherapy session.  His presence and story alone are a compelling argument against the lethal carcinogenic combination of alcohol and smoking.

Please take a look at the interview here:   

The loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?

According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites.

Dr. Jeremy Mao, the Edward V. Zegarelli Professor of Dental Medicine at Columbia University Medical Center, has unveiled a growth factor-infused, three-dimensional scaffold with the potential to regenerate an anatomically correct tooth in just nine weeks from implantation. By using a procedure developed in the university's Tissue Engineering and Regenerative Medicine Laboratory, Dr. Mao can direct the body's own stem cells toward the scaffold, which is made of natural materials. Once the stem cells have colonized the scaffold, a tooth can grow in the socket and then merge with the surrounding tissue.

Dr. Mao's technique not only eliminates the need to grow teeth in a Petri dish, but it is the first to achieve regeneration of anatomically correct teeth by using the body's own resources. Factor in the faster recovery time and the comparatively natural process of regrowth (as opposed to implantation), and you have a massively appealing dental treatment.

Columbia University has already filed patent applications in regard to the technology and is seeking associates to aid in its commercialization. In the meantime, Dr. Mao is considering the best approach for applying his technique to cost-effective clinical therapies.

Brushing Techniques

April 16, 2010 | Posted Oral Hygiene | 2 - Comments

Brushing is the most effective method for removing harmful plaque from your teeth and gums. Getting the debris off your teeth and gums in a timely manner prevents bacteria in the food you eat from turning into harmful, cavity causing acids.

Most dentists agree that brushing three times a day is the minimum; if you use a fluoride toothpaste in the morning and before bed at night, you can get away without using toothpaste during the middle of the day.

A simple brushing with plain water or rinsing your mouth with water for 30 seconds after lunch will generally do the job.
