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.
If you suffer frequent sinus infections, you might want to talk with your dentist about it. It could be your chronic sinus problems stem from a deeply decayed or infected tooth.
Sinuses are hollow, air-filled spaces in the front of the skull associated with nasal passages. The largest, the maxillary sinuses, are located just behind the cheekbones and above and to the rear of the upper jaw on either side of the face. These sinuses can become painfully congested when infected.
One possible cause for an infection in the maxillary sinus can occur in certain people whose upper back teeth (the molars and premolars) have roots that are close to or even protrude into the sinus. This is normally a minor anatomical feature, unless such a tooth becomes infected.
An infection in teeth with advancing decay or whose nerve tissue has died will eventually reach the root tip through tiny passageways called root canals. If the roots are close to or penetrating the maxillary sinus, the infection could move into the sinus. This is known as Maxillary Sinusitis of Endodontic Origin (MSEO).
A case of MSEO could potentially go on for years with occasional flare-ups of sinus congestion or post-nasal drip. Because of the nature of the infection within the sinus, the affected tooth itself may not show the normal signs of infection like sensitivity or pain. Doctors may attempt to treat the sinus infection with antibiotics, but because the actual source of the infection is within the tooth, this therapy is often ineffective.
If your doctor or dentist suspects MSEO, they may refer you to an endodontist, a specialist in root canals and interior tooth problems. With their advanced diagnostic capabilities, endodontists may have a better chance of accurately diagnosing and locating the source of a tooth-related infection.
As with any non-vital tooth, the likely treatment will be root canal therapy in which the infected tissue within the tooth is removed and the empty spaces filled to prevent future infection. For MSEO, the treatment not only preserves the tooth but may also relieve the infection within the sinus.
All-natural fruit juice with no additives: now what could be wrong with that? Nothing—unless your child is over-indulging. Too much of even natural fruit juice could increase their risk of tooth decay.
To understand why, we first need to look at the real culprit in tooth decay: mouth acid produced by oral bacteria as a byproduct of their digestion of sugar. Acid at high levels softens and erodes tooth enamel, which causes tooth decay. Acid levels can rise as populations of bacteria increase often fueled by sugar, one of bacteria's primary food sources.
And not just the added sugar found in soft drinks, snacks or candies—even fructose, the natural sugar found in fruit, can feed bacteria. To lower the risk of tooth decay, dentists recommend limiting the daily amount of sugar a child consumes, including natural fruit juices without added sugar.
That doesn't mean you should nix natural fruit juices altogether—they remain a good source of vitamins, minerals and other nutrients. But you'll need to keep your child's juice consumption within moderation.
As a guide, the American Academy of Pediatrics (AAP) has issued consumption recommendations for children regarding all-natural fruit juice. The academy recommends the following daily juice amounts by age:
- 7-18: 8 ounces (1 cup) or less;
- 4-6: 6 ounces or less;
- 1-3: 4 ounces or less;
- Under 1: No juice at all.
You can further reduce your child's decay risk by limiting their juice intake to mealtimes, a good practice with any sweetened beverage. Sipping through the day on juice or other sweetened beverages can cause some sugar to stay in the mouth over long periods. This can interfere with the natural ability of saliva to neutralize any acid buildup.
If you're wondering what children could drink instead of juice, low-fat or non-fat milk is an acceptable choice. But the most tooth-friendly liquid to drink is plain water. Drinking nature's hydrator is not only better for their overall health, by reducing the risk of tooth decay, it's also better for their teeth.

Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

Dental caries (tooth decay) is a leading cause of tooth loss. But with prompt diagnosis and care we can often stop it before it causes too much damage.
The traditional treatment approach is simple: remove all diseased tooth structure and then restore the tooth with a filling. But this otherwise effective treatment has one drawback: you may lose significant healthy structure to accommodate a suitable filling or to make vulnerable areas easier to clean from bacterial plaque.
That's why a new treatment approach called minimally invasive dentistry (MID) is becoming more common. The goal of MID is to remove as little of a tooth's natural enamel and dentin as possible. This leaves the treated tooth stronger and healthier, and could reduce long-term dental costs too.
Here's how MID could change your future dental care.
Better risk assessment. MID includes a treatment protocol called caries management by risk assessment (CAMBRA). With CAMBRA, we evaluate your individual tooth decay risk, including oral bacteria levels, the quality of saliva flow to neutralize mouth acid, and sugar consumption. We then use our findings to customize a treatment plan that targets your areas of highest risk.
New detection methods. The real key to fighting tooth decay is to find it before it can destroy tooth structure with the help of new diagnostic technology. Besides advances in x-ray imaging that provide better views with less radiation exposure, we're also using powerful dental microscopes, lasers and infrared photography to show us more about your teeth than we can see with the naked eye.
"Less is More" treatments. In contrast to the dental drill, many dentists are now using air abrasion rather than a dental drill to remove decayed tooth material. Air abrasion emits tiny material particles within a pressurized air stream that leaves more healthy tooth structure intact than with drilling. We're also using new filling materials like composite resin that not only resemble natural tooth color, but require less structural removal than other types of fillings.
Using MID, we can treat tooth decay while preserving more of your natural teeth. This promises better long-term outcomes for future dental health.
