According to a recent study by British researchers, in order to reduce the significant financial and social burdens of dental decay, free sugars in the diet should make up no more than 3% of total energy intake.

Dental decay (caries) is the most common chronic disease worldwide, affecting 60% to 90% of schoolchildren and the majority of adults. In the U.S., 92% of adults ages 20 to 64 have had caries in at least one of their permanent teeth. The treatment of dental diseases costs 5% to 10% of total health expenditure in industrialized countries.

The study findings indicate that current approaches to controlling dental caries are failing to prevent high levels of caries in… (Read More)

Contrary to what many denture-wearers believe, dentures require regular maintenance, including relines, repairs, and replacement. In fact, the average denture should be relined every two to three years and replaced every five to seven years for the most optimal fitting prosthesis. There are many reasons for this maintenance interval and for regular dental examinations, whether or not the patient perceives any problem.

The first problem has to do with the basic function of the bone surrounding natural teeth. Natural teeth are held in their sockets by thousands of “cables”, called the periodontal ligament that tug and pull on the supporting bone during function. The bone is designed to be strengthened and stimulated in this manner.… (Read More)

Do you have any problems with dental decay (cavities), gum recession, and/or dental erosion (the chemical breakdown of tooth structure)? These dental issues are complicated multifactorial diseases of epidemic levels affecting both children and adults. A healthy mouth sometimes requires more than brushing, flossing, and “fillings”. With current scientific evidence and new technologies, patients and practitioners need to begin to look at these problems not just from a drilling and filling approach, but also from a medical (preventive/therapeutic) approach.

There are over 19,000 different bacteria that have been found in mouths and every person has about 1,000 different types. Not all of them cause decay, but many of them have also been found to grow… (Read More)

If all dental offices do the same thing – treat teeth – why are there so many variables between different offices?

Each office takes on the characteristics of the practitioner who owns it.  The personality of the owner is probably the key to how that office “feels” when you walk in the door.  Some practices may feel “clinical and efficient”, while others feel somewhat more home spun and laid back.  The dentist’s personality is reflected in his or her treatment preferences as well.  The fact that different dentists will suggest different plans to treat your condition does not necessarily mean that one plan is better than another.

Most dentists will suggest what they feel to… (Read More)

With more than 24 million diabetics and 57 million pre-diabetics in the United States, nearly a quarter of the nation’s population, there are a lot of people affected by diabetes. The prevalence of diabetes will increase by 54% to more than 54.9 million Americans between 2015 and 2030; annual deaths attributed to diabetes will climb by 38% to 385,800. In addition, the most up to date research shows the connection between dental health and diabetes has never been more critical.

As an indication of our general health, the rapidly rising rate of diabetes should be ringing alarm bells everywhere. The litany of health implications from diabetes is a long and grisly list. It is the… (Read More)

It’s a mild spring day and you’re out with your family enjoying a delicious serving of ice cream, when all of a sudden, you feel a twinge of discomfort in your front teeth from your cold dessert. You wonder, “Why did this happen – Do I have to avoid ice cream from now on?” Your local dentist says that there are ways to address your sensitive teeth, so that you can once again enjoy life. Learn about them as you read on!

A Harvard-led study published in the journal, Science Translational Medicine, has determined that the use of low-powered lasers can stimulate stem cells enough to regenerate and grow rat teeth and human dental tissue. This concept may seem barbaric, but it could be a metamorphic tool in the constantly evolving world of dentistry.

Researchers have been trying to figure out new ways to use the versatility of stem cells since they exist in abundance throughout the human body. Stem cells are unique in the sense that they can become different types of cells, making them prime candidates to repair or replace damaged tissue.

Although the research is still in its earliest stages and has yet to… (Read More)

One of my great patients, Malcolm, recently sent me an article he received from his Alma Mater entitled “Risky Bristles”. Malcom wanted me to share some information with you about triclosan.

According to the Environmental Protection Agency, triclosan is an antimicrobial agent that helps to “slow or stop the growth of bacteria, fungi, and mildew.” It first started to appear in antibacterial hand soap products in the 1970’s.

Since then, according to the Center for Disease Control, “it has been used in consumer products such as detergents, soaps, skin cleansers, deodorants, lotions, creams, toothpastes, and dishwashing liquids.” Many products labeled as “antibacterial” may contain triclosan or related compounds.

One of those products that contains triclosan… (Read More)

It seems I have more and more patients telling me about their upcoming shoulder, hip, and knee replacement surgery. There are other parts that people have replaced, but those are the top three. Most of these people decide to go under the knife to improve their quality of life.

If you were born in the Paleolithic era, you could expect to live to 33 years old. The average global life expectancy in 2010 was more than double this number at 67 years. The main reasons for this are advances in hygiene, food production, and medical care.

On the bright side, if you were born in the Paleolithic era, you would most likely never need a… (Read More)
