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.
While most tooth loss stems from dental disease or injury, another major cause is a condition known as cracked tooth syndrome. What begins as a microscopic crack in an individual tooth’s enamel could ultimately grow to a fracture that endangers its survival.
Most often related to age-related brittleness, expansion and contraction of the enamel surface because of hot foods followed by cold foods and beverages, or grinding habits, cracked tooth syndrome usually occurs in three phases. The first phase is the emergence of miniscule cracks in the outer enamel known as craze lines. These can be very difficult to detect even with x-rays, and usually calls for specialized detection methods such as probing with a sharp instrument (an explorer) or fiber-optic lighting with dye staining to highlight enamel abnormalities. If you have pain symptoms, we may ask you to bite down on a bite stick or rubber pad to locate the area by replicating the sensation.
In the next phase, the craze line grows into a crack that penetrates below the enamel into the tooth’s dentin. Pain becomes more prominent and the risk of infection increases. Left untreated, the crack may enter the third phase, a full break (fracture) occurring deep within the inner layers of the tooth. The deeper the fracture occurs, the more serious the danger to the tooth, especially if the pulp is exposed.
The best treatment approach is to attempt to detect and treat a crack as early as possible. Craze lines and moderate cracks can usually be repaired with restorative materials like composite resins. A deeper crack extending into the pulp may require a root canal treatment and the tooth covered with a permanent, protective crown.
If, however, the fracture is too deep, the tooth may be beyond repair and will need to be extracted and replaced with a dental implant or permanent bridge. In any event, the sooner a cracked tooth is discovered and treated, the greater your chance of avoiding pain, discomfort, and, ultimately, tooth loss.

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.

If you're one of the millions of people wearing an oral appliance, you already know how important it is to your dental health. Whatever the purpose—replacing teeth, stopping teeth grinding or guarding against injury—you want to get the most and longest service from it. That means showing your appliance some tender loving care on a regular basis.
It doesn't require a lot of time and effort to clean and maintain your oral appliance. But there are some pitfalls that could lead to greater wear and tear and just outright damage. Here are 3 things you should be on the alert for to keep your appliance doing its job for you.
Be careful how you clean it. Your appliance might resemble natural oral tissue, but it's not—so don't use toothpaste. Toothpaste contains abrasives, which are fine for tooth enamel but damaging to materials in your appliance. Instead, use dish detergent, hand soap or a specialized cleaner. Don't use hot or boiling water, which could soften any plastic and distort the appliance's mouth fit. Nix the bleach too, which can fade colored portions of the appliance that mimic gum tissue.
Don't wear them 24/7 unless your dentist advises. Depending on the type and function of your appliance, you shouldn't wear them around the clock unless your dentist advises otherwise. Dentures are usually removed at night while you sleep to help prevent bacterial growth. Keeping them out at night -and keeping them clean—will help lower your risk of dental disease. One caveat, though: there are some concerns today about the effect of keeping dentures out of the mouth at night on sleep apnea. It's a good idea, then, to discuss the issue with your dentist regarding taking dentures out at night.
Prevent accidental drops on hard surfaces. Chewing forces are considerable, but your appliance is designed to take it. The same can't be said, though, if they accidentally fall on a hard surface—the fall could crack or break them. To protect against this, be sure to put a soft towel or cloth in your sink basin while you're cleaning your appliance. And don't place it on a night stand or low surface where it could be knocked off accidentally by a child, a pet or you. A sudden accident like this could be costly.

If you had chicken pox as a child, you're at higher risk for a painful viral infection later in life called shingles. Besides a painful skin rash and other symptoms that can develop, shingles could also affect your dental care.
About 90% of children contract chicken pox, a disease caused by the varicella zoster virus (VZV), which usually clears up on its own. But later in life, usually after age 50, about a quarter to a third of chicken pox patients will develop shingles.
The onset of shingles usually produces an itching or burning sensation on the skin that's either numb or overly sensitive to the touch. A red rash may ensue with crusty lesions, accompanied sometimes by pain, fever and fatigue. The rash often forms a belt-like or striped pattern along one side of the face or body.
For most patients this painful rash is the extent of their symptoms. But women who are pregnant, patients undergoing cancer treatment or people with compromised immune systems are at risk for more serious complications if they contract the disease. It's important for these at-risk patients to obtain a vaccination, as well as avoid contact with anyone with shingles.
Which brings us to your dental care: in its early stages shingles can be contagious, the virus passing to others through skin contact or by airborne respiratory secretions. That's why it's important if you're currently experiencing a shingles episode that you let us know before undergoing any kind of dental work.Â Even a routine teeth cleaning with an ultrasonic device could disrupt the virus and increase the chances of it spreading to someone else. We may need to postpone dental work until the virus is under control.
Antiviral drugs like acyclovir or famciclovir are highly effective in bringing the disease under control, especially if treatment starts within three days of the onset of symptoms. And don't forget the shingles vaccination: the U.S. Center for Disease Control recommends it for anyone 60 or older regardless of a past history with chicken pox.
See your physician as soon as possible if you begin to notice symptoms. Don't let shingles interfere with your life — or your dental care.
