Why does orange juice taste so bad after brushing your teeth?

What is it about toothpaste that transforms the sweet flavor of orange juice into something so bitter? For the solution to that mysterious sensory phenomenon - in colorful, animated detail - check the latest episode of the American Chemical Society's award-winning Bytesize Science video series at http://www.bytesizescience.com/ 

The video, from the world's largest scientific society, explains that the mainstay ingredients in toothpaste include a detergent called sodium lauryl sulfate, or SLS for short. When you brush your teeth, SLS produces the foamy suds and gives toothpaste its distinct mouth-feel. SLS also influences the way your personal, powerful chemical sensor tastes food. 

That sensor is your mouth, with its 10,000 individual taste buds. Each consists of scores of receptor cells that respond to the basic tastes. Those are sweet, sour, bitter, salty and umami (a pleasant, brothy or meaty flavor). Nerves carry the resulting signals to the brain, which registers tastes. How does SLS affect your sense of taste? For the answer:

Soda = meth/crack for you teeth


The Academy of General Dentistry (AGD) recently published a case study comparing the consumption of illegal drugs to the abusive intake of soda.  Now before you panic and stop drinking your sodas altogether, the distinction here is abusive intake of soda.  They categorize abusive soda intake as 2 liters of soda a day for 3 to 5 years.
They found that abusive soda intake is just as destructive to your teeth as methamphetamine use or crack cocaine use.  Each participant in this study admitted to having poor oral hygiene and not visiting a dentist on a regular basis. Researchers found the same type and severity of damage from tooth erosion in each participant’s mouth.
“Each person experienced severe tooth erosion caused by the high acid levels present in their ‘drug’ of choice—meth, crack, or soda,” says Mohamed A. Bassiouny, DMD, MSc, PhD, lead author of the study.
“The citric acid present in both regular and diet soda is known to have a high potential for causing tooth erosion,” says Dr. Bassiouny.
As the release states, similar to citric acid, the ingredients used in preparing methamphetamine can include extremely corrosive materials, such as battery acid, lantern fuel, and drain cleaner. Crack cocaine is highly acidic in nature, as well.
The individual who abused soda consumed two liters of diet soda daily for three to five years. Says Dr. Bassiouny, “The striking similarities found in this study should be a wake-up call to consumers who think that soda—even diet soda—is not harmful to their oral health.”
AGD Spokesperson Eugene Antenucci, DDS, FAGD, recommends that his patients minimize their intake of soda and drink more water. Additionally, he advises them to either chew sugar- free gum or rinse the mouth with water following consumption of soda. “Both tactics increase saliva flow, which naturally helps to return the acidity levels in the mouth to normal,” he says.

Veneers

One of the most rewarding aspects of dentistry is helping people to smile with more confidence.  We love to create beautiful smiles here at Park City Dentistry.  We pride ourselves on the quality of our cosmetic dentistry.  Here is a wonderful example of how much we can improve someone's smile with just a little work.

This young lady came to us with a very "gummy" smile.  She also had a discolored and misshapen filling on the front tooth.  She had braces previously as a teenager, but didn't like how short her teeth were or the gaps that were visible even when she was biting down.

We worked with our periodontist to adjust the level of her gums.  After she healed from that, we gave her veneers on her front 4 teeth, and the results were quite drastic.  She loves her smile, and we are very pleased with the final product.  Pretty impressive before and after difference.  The lab we work with to make the veneers has an incredible ability to make them look so natural and life like.

Are you dissatisfied with your teeth and their appearance?  If so, come in for a consult to see what options you have to improve your smile.

King Richard III

(A plastic facial model made from the recently discovered skull of England’s King Richard III)

Earlier this year the body of King Richard III was discovered underneath a parking lot in Leicester, England.  He was buried in this spot (formerly the site of the Grey Friars Church) in 1485 after dying from massive blows to the head sustained during the Battle of Bosworth in the War of Roses.

He was the last English king to die in battle.  Researchers examined his teeth and concluded that he ground his teeth due to an overwhelming amount of stress.  It is supposed that much of this stress was caused by guilt after he murdered his brothers in order to become the King of England. Researchers  also concluded that he had an alarming amount of tooth decay which could be from a diet high in carbohydrates and sugar.

Along with his stress-related bruxism and severe tooth decay, Dr. Amit Rai, a London general dental practitioner, claims in a paper for the British Dental Journal, that the king had a significant amount of tartar build up. He also suggests that his jaw and teeth show evidence of medieval dentistry and at least two tooth extractions most likely performed by barber surgeons.  So, if you ever wondered whether or not your tartar would decay on its own, well now you have proof that even after more than 500 years, it is still there.

The paper has some cool dental anthropology for you science minded people.
