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.
Watching your kids dress up in cute, spooky costumes and go out trick-or-treating can be a real thrill. But thinking about the dental damage caused by eating all those sweets might just give you the chills. So is it best to act like a witch and take away all the candy from those adorable little ghosts and goblins?
Relax! According to experts like the American Dental Association, it’s OK to let kids enjoy some sweet treats on special occasions like Halloween—especially if they have been taking good care of their oral hygiene all year long, by brushing twice each day and flossing once every day. But to help keep cavities away from those young smiles, there are some things parents (and everyone else) should understand.
Cavities—small holes in the tooth’s outer surface that result from the decay process—get started when bacteria in the mouth feed on sugar and produce acids. The acids eat away at the hard enamel coating of teeth. If left untreated, decay will eventually reach the soft inner core of the tooth, causing even more serious damage.
There are several ways to stop the process of tooth decay. One is to take away the sugar that decay bacteria feed on. Because this ingredient is common in so many foods, it’s hard to completely eliminate sugar from the diet. Instead, it may be more practical to limit the consumption of sweets. For example, if kids are only allowed to eat sugary treats around mealtimes, it gives the mouth plenty of “downtime,” in which healthful saliva can neutralize the bacterial acids. It also helps to avoid sweets that stick to teeth (like taffy or gummy bears) and those that stay in the mouth for a long time (like hard candy).
Another way to help stop tooth decay is by maintaining top-notch oral hygiene. Decay bacteria thrive in the sticky film called plaque that clings stubbornly to the surfaces of teeth. Plaque can be removed by—you guessed it—effective brushing and flossing techniques. While it’s a good start, brushing alone won’t remove plaque from the spaces between teeth and under the gums: That’s why flossing is an essential part of the daily oral hygiene routine. Helping your kids develop good oral hygiene habits is among the best things you can do to fight cavities.
And speaking of habits, there are a few others that can help—or hurt—your oral health. For example, drinking plenty of water keeps the body hydrated and benefits oral health; but regularly drinking soda and other sweetened or acidic beverages greatly increases the risk of tooth decay. And seeing your dentist on a regular basis for professional cleanings and routine checkups is one of the most beneficial habits of all. Working together, we can help keep tooth decay from turning into a scary situation for kids—and adults too.

High school graduation marks the end of childhood and the beginning of young adulthood. Do you have a graduate in your family? If so, this is the ideal time to schedule a dental checkup and cleaning. Many graduates will be moving away to attend college, and an oral exam and cleaning now can help ensure that they will embark on this next phase of life in good oral health.
Is your graduate ready for the barrage of camera snaps? Long after graduation day, pictures of your graduate beaming in cap and gown will be on display. A professional teeth cleaning may be just what is needed for a camera-ready smile. The dental hygienist will use an electronic polishing tool to remove many stains from the teeth for a sparkling smile.
What’s more, the dental hygienist uses special tools to get rid of plaque and tartar that can cause bad breath, a common concern among teens and young adults. Bad breath is primarily caused by poor oral hygiene habits, and the hygienist can check to see if your teen’s oral hygiene routine has been too lax—and offer pointers if needed. It’s never too late to form better brushing and flossing habits, especially if your graduate will soon be living away from home!
A dental exam will reveal tooth decay or gum disease, problems that will only get worse if not taken care of. Another reason why dental exams are important at this time is that wisdom teeth—or third molars—generally appear between ages 17–21. Although these teeth sometimes come in without any problem, many wisdom teeth become impacted and must be removed, so it’s important to monitor them during regular dental checkups.
Take time to schedule a dental exam and cleaning so your graduate can march into a bright future armed with a big smile and the best oral health.

Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
