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.
Each year doctors treat about 150,000 new cases of severe facial pain. If you're one of those people, you don't have to suffer—there are ways to gain relief from these painful episodes.
Those recurring episodes are known as trigeminal neuralgia (TN). As the name implies, the source of the pain are the trigeminal nerves, which originate in the brain stem and extend on either side of the face. Each is divided into three branches (hence the "tri" in trigeminal) that serve the upper, middle and lower parts of the face and jaw.
TN can involve one or more of these branches, resulting in mild to severe pain that can last for several seconds. Jaw movements like chewing or speaking can trigger an episode, as well as a light touch to the face.
There are various proposed causes for TN, including links with inflammatory disorders like multiple sclerosis, which damages the insulating sheathing around nerve cells. The most common cause, though, appears to be a blood vessel pressing against the nerve. The compression causes hypersensitivity in that area of the nerve so that it transmits pain at the slightest sensation.
Other conditions like jaw joint pain disorders (TMD) or a dental abscess can cause similar pain symptoms, so it's important to get an accurate diagnosis. If your doctor does identify your condition as TN, you may then need a comprehensive approach to treatment involving a team of care providers, including your dentist.
For the most part, TN can be managed, beginning with the most conservative approach to gain relief, often with medications to block the nerve's pain signals to the brain or decrease abnormal nerve firings. If that proves insufficient, though, more intensive treatments are available.
One possible treatment for an impinging blood vessel is a microsurgical procedure to expose the affected nerve and relocate the vessel. While this can be effective, the surgery does carry some risk of facial numbness or decreased hearing. If the risks are too high for conventional surgery, an alternative procedure uses a precise beam of high-dose radiation to relieve the pressure from the vessel.
The most important thing to know about TN, though, is that it is possible to control it and relieve future pain episodes. If you're experiencing these symptoms, see your dentist or doctor for an exam and accurate diagnosis.

Have damaged teeth? If so, dental crowns may just be the solution you need to strengthen your damaged teeth. Dental crowns are dental caps your general dentist can put on your teeth. Dental crowns are used to fix badly decayed and damaged teeth. Led by Dr. Tamara Simons, Roseville Dentistry (which is located in Roseville, MN) offers high-quality crowns to the patients they serve. Read on to find out how crowns help keep your teeth strong.
Fix Your Damaged Teeth
Crowns are dental restorations that cover the outside of the teeth. They're used to restore fractured and badly decayed teeth. Crowns are also used to protect teeth after root canal therapy. Crowns are made from several types of materials. Ceramic, composite resin, porcelain, or a combination of these materials may be used. If you need crowns, putting off treatment could jeopardize the health of your teeth and cause them to be damaged beyond repair.
Strengthen Your Teeth
Dental crowns are tough like natural teeth. Porcelain-fused-to-metal dental crowns have a metal layer underlying and ceramic on top of it. Porcelain-fused-to-metal crowns are known for their exceptional durability and great strength. Porcelain dental crowns are made from a glass-like substance, which is attractive to look at. Porcelain dental crowns are incredibly strong and produce pleasing aesthetics.
Improve Oral Function
Dental crowns can improve oral function. It's very difficult to eat when you have damaged teeth. Dental crowns will give you the ability chew all your favorite foods again. Dental crowns can withstand biting and chewing forces well. Crowns will restore the structure of your teeth so you can eat in comfort and with confidence. With dental crowns in place, you'll be able to eat whatever you want, whenever you want.
Maintain a Healthy Smile
Dental crowns from your general dentist in Roseville, MN, can last for up to 10-15 years. However, when taken care of properly, it is common to see them last upwards of 20-25 years. For best results, floss and brush regularly to keep plaque at bay. Dental crowns will last longer if they aren't exposed to too much wear and tear. Things like grinding or clenching your teeth, chewing on ice and ripping open packages with your teeth can all limit the life expectancy of dental crowns.
Take the first steps to a healthy smile. Call your general dentist at Roseville Dentistry at 651-489-1900 right now to schedule a dental consultation in Roseville, MN, and get the smile you deserve. Knowing that you have a healthy, beautiful smile can go a long way toward improving your life!
Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

Teeth whitening or bleaching is one of the most affordable and least invasive ways of improving your smile. Although the effect fades with time, whitening can make dull and dingy teeth more attractive in short order.
Teeth whitening is also unique among cosmetic dental procedures in that you can do it yourself at home. While professional bleaching solutions are stronger and capable of greater brightness and longevity, you can still achieve good results with a DIY kit.
If you decide to whiten at home, though, there are a few things to keep mind for a desirable and safe outcome. Here are 3 tips for successful DIY teeth whitening.
Follow the directions. It's not a good idea, both for a successful and safe outcome, to stray away from a kit manufacturer's recommended directions. FDA-approved home kits usually contain 10% or less of carbamide peroxide (one of the more common bleaching agents). That may not seem very strong but it's adequate within the recommended time it remains on your teeth to achieve an effective whitening effect. Exceeding those directions could permanently damage your tooth enamel.
Make sure a home kit will work on your staining. Home whitening kits only affect outer staining on tooth enamel. But dental discoloration can also arise from inside a tooth, often because of trauma, tetracycline use, or as a side effect of a root canal treatment. This kind of internal staining requires a special procedure usually performed by an endodontist to reduce it. So, see your dentist first to make sure your teeth are healthy enough for whitening and that a home kit will work for you.
Get your dentist's advice on home kits. There are a number of whitening applications on the market you can choose, so ask your dentist for recommendations. They can also give you some helpful tips on the whitening process to ensure you'll be safe and successful in your efforts.
Here's a couple of other things to remember to enhance your teeth whitening experience: whether you whiten your teeth at home or with the dentist, be sure you continue to care for your teeth with daily brushing and flossing. And, if you limit your consumption of foods and beverages known to stain teeth, you'll help extend the duration of your brighter smile.
