Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
The 2019 Grammy Awards was a star-studded night packed with memorable performances. One standout came from the young Canadian singer Shawn Mendes, who sang a powerful duet of his hit song "In My Blood" with pop diva Miley Cyrus. But that duo's stellar smiles weren't always quite as camera-ready as they looked that night.
"I had braces for four and a half years," Mendes told an interviewer not long ago. "There's lots and lots and lots of photo evidence, I'm sure you can pull up a few." (In fact, finding one is as easy as searching "Sean Mendes braces.")
Wearing braces puts Mendes in good company: It's estimated that over 4 million people in the U.S. alone wear braces in a typical year—and about a quarter of them are adults! (And by the way: When she was a teenager, Miley Cyrus had braces, too!)
Today, there are a number of alternatives to traditional metal braces, such as tooth-colored braces, clear plastic aligners, and invisible lingual braces (the kind Cyrus wore). However, regular metal braces remain the most common choice for orthodontic treatment. They are often the most economical option, and can be used to treat a wide variety of bite problems (which dentists call malocclusions).
Having straighter teeth can boost your self-confidence—along with helping you bite, breathe, chew, and even speak more effectively. Plus, teeth that are in good alignment and have adequate space in between are easier to clean; this can help you keep your mouth free of gum disease and tooth decay for years to come.
Many people think getting braces is something that happens in adolescence—but as long as your mouth is otherwise healthy, there's no upper age limit for orthodontic treatment. In fact, many celebrities—like Lauren Hutton, Tom Cruise and Faith Hill—got braces as adults. But if traditional braces aren't a good fit with your self-image, it's possible that one of the less noticeable options, such as lingual braces or clear aligners, could work for you.
What's the first step to getting straighter teeth? Come in to the office for an evaluation! We will give you a complete oral examination to find out if there are any problems (like gum disease or tooth decay) that could interfere with orthodontic treatment. Then we will determine exactly how your teeth should be re-positioned to achieve a better smile, and recommend one or more options to get you there.
If you have questions about orthodontic treatment, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Magic of Orthodontics” and “Lingual Braces: A Truly Invisible Way to Straighten Teeth.”
In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.
Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.
Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.
Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.
By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.
If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.
Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.
While pregnancy is an exciting time for expectant mothers, it can pose extra health challenges. This is especially true regarding dental health.
Because of hormonal changes that naturally occur during pregnancy, your teeth and gums are at higher risk for dental disease. These changes can increase cravings for carbohydrates, particularly sugar. Increased sugar consumption feeds bacteria found in dental plaque, which is most responsible for tooth decay and periodontal (gum) disease.
Hormonal changes can also make your gums more susceptible to infection. Conditions may be favorable for a form of gum disease called pregnancy gingivitis, which can begin as an infection in the surface layers of the gums. But like other forms of gum disease, pregnancy gingivitis can advance below the gum line and lead to serious health consequences.
Because of this "pregnancy effect" on your teeth and gums, there are some things to which you should pay heed while you're expecting. First and foremost, keep up a daily regimen of brushing and flossing to remove accumulated dental plaque. You should also control your sugar intake to minimize bacterial growth that can cause disease.
It's also important for you to continue regular dental visits during your pregnancy. Your dentist will monitor your dental health and initiate treatment if you begin to show signs of disease. Besides professional cleanings, your dentist may also prescribe antibacterial mouthrinses to combat bacteria.
As far as dental procedures, essential treatments like fillings, root canals or extractions are usually considered safe to perform during pregnancy. But elective treatments of a cosmetic nature are best postponed until after your baby's delivery.
One last tip: because of the higher risk of tooth decay or gum disease, be on the lookout for any abnormal signs in your mouth. This includes spots on the teeth, tooth pain or swollen, reddened or bleeding gums. If you see any of these signs, see your dentist as soon as possible.
Your teeth and gums are indeed at risk for disease during pregnancy. But daily hygiene, regular dental care and attention to signs of disease can help keep that danger at bay.

While wearing braces is the path to a healthier and more attractive smile, it can be a difficult journey. One of your biggest challenges will be keeping your teeth clean to avoid a higher risk of tooth decay.
Tooth decay starts with dental plaque, a thin film of bacteria and food particles that accumulates on teeth. Daily brushing and flossing clear this accumulation. But the hardware of braces makes it difficult to access all tooth surfaces, and can even become a haven for plaque.
One sign in particular of tooth decay while wearing braces is the appearance of chalk-like spots on the teeth known as white spot lesions (WSLs). WSLs occur because the minerals in the enamel beneath them have begun to break down in response to decay. The spots can eventually cause both structural and cosmetic problems for a tooth.
The best approach to WSLs is to prevent them from developing in the first place. You'll need to be extra vigilant with daily oral hygiene while wearing braces to reduce plaque buildup. To help with the increased difficulty you might consider using a special toothbrush designed to maneuver more closely around orthodontic hardware. You may also find using a water flosser to be a lot easier than flossing thread.
Preventing tooth decay and WSLs also includes what you eat or drink to reduce the effects of enamel de-mineralization. The bacteria that cause decay thrive on sugar, so limit your intake of sweetened foods and beverages. And to avoid excessive demineralization cut back on acidic foods as well.
If despite your best preventive efforts WSLs still form, we can take steps to minimize any damage. For one, we can give your enamel a boost with fluoride applications or other remineralization substances. We can also inject a tooth-colored resin beneath the surface of a WSL that will make it less noticeable.
With any of these and other treatments, though, the sooner we can treat the WSL the better the outcome. Practicing good hygiene and dietary habits, as well as keeping an eye out for any WSL formations, will do the most to protect your new and improved smile.
