Tooth decay is one of two dental diseases most responsible for tooth loss (gum disease being the other). In the absence of treatment, what starts as a hole or cavity in a tooth's outer layers can steadily advance toward its interior.
Most people associate cavities with the crown, the part of a tooth you can see. But cavities can also occur in a tooth's roots, especially with older adults. Root cavities pose two distinct difficulties: They can lead to more rapid decay spread than crown cavities within a tooth; and they're harder to detect.
Tooth roots are ordinarily covered by the gums, which protects them from bacterial plaque, the main cause for decay. But roots can become exposed due to receding gums, a common problem with seniors who are more susceptible to gum disease.
Unlike the enamel-covered crowns, tooth roots depend on gum coverage for protection against bacteria and the acid they produce. Without this coverage, the only thing standing between tooth decay and the roots is a thin material called cementum.
If decay does enter a tooth's interior, saving it often requires a root canal treatment to remove decayed tissue in the inner pulp and root canals, and then replacing it with a filling. But if we're able to discover a root cavity in its early stages, we may be able to fill it like a crown cavity.
The best strategy, though, is to prevent root cavities from forming. This starts with a dedicated daily regimen of brushing and flossing to remove dental plaque. If you're at high risk for root cavities, we may also recommend antibacterial mouthrinses and other aids.
Regular dental visits are also a must: a minimum of twice-a-year dental cleanings to remove stubborn plaque and calculus (hardened plaque) deposits. For added protection against root cavities, we can also apply fluoride varnish to strengthen teeth. And regular visits are the best way to detect any cavity in its early stages when treatment is less invasive.
A heightened risk of dental problems like root cavities are a part of the aging process. But partnering together, we can lower that risk and increase the longevity of your teeth.

While dental diseases tend to be a greater concern as we get older, they also pose a potential threat to children. A particular type of tooth decay called early childhood caries (ECC) can severely damage children's unprotected teeth and skew their normal dental development.
Fortunately, you can protect your child's teeth from disease with a few simple practices. First and foremost: start a hygiene habit as soon as possible to remove disease-causing bacterial plaque. You don't have to wait until teeth appear, either: simply wipe the baby's gums with a clean wet cloth after nursing to minimize the growth of oral bacteria.
When their teeth do begin to erupt, you can switch to brushing (you can add flossing as more teeth erupt—but until the child shows appropriate dexterity, you'll need to do it for them). For infants, brush gently but thoroughly with a soft-bristled brush and a smear of fluoride toothpaste. When they grow older you can increase the toothpaste to a pea-sized amount. And as soon as you can, get them involved with learning to perform these vital habits on their own.
You should also limit your child's consumption of sugar. Our favorite carbohydrate is also a favorite of bacteria, who consume any remnants in dental plaque as a primary food source. So, keep sugary snacks and foods to a minimum and limit them mainly to mealtimes. And don't put a baby to sleep with a bottle filled with a liquid containing sugar (including formula and breastmilk).
Finally, begin taking your child to the dentist regularly by their first birthday for routine cleanings and checkups. Besides removing any hard to reach plaque, your dentist may also apply sealants and topical fluoride to help protect and strengthen tooth enamel. Regular visits make it more likely to detect the early signs of decay, before it does extensive damage. And beginning early makes it less likely your child will develop a fear of dental visits that could carry on into adulthood.
These and other steps will go a long way in protecting your child's teeth and gums so they develop normally. A little prevention and protection will help ensure a happy, healthy smile later in life.

A root canal treatment is a common procedure performed by dentists and endodontists (specialists for inner tooth problems). If you're about to undergo this tooth-saving procedure, here's what you need to know.
The goal of a root canal treatment is to stop tooth decay within a tooth's interior and minimize any damage to the tooth and underlying bone. This is done by accessing the tooth's pulp and root canals (tiny passageways traveling through the tooth roots to the bone) by drilling into the biting surface of a back tooth or the "tongue" side of a front tooth.
First, though, we numb the tooth and surrounding area with local anesthesia so you won't feel any pain during the procedure. We'll also place a small sheet of vinyl or rubber called a dental dam that isolates the affected tooth from other teeth to minimize the spread of infection.
After gaining access inside the tooth we use special instruments to remove all of the diseased tissue, often with the help of a dental microscope to view the interior of tiny root canals. Once the pulp and root canals have been cleared, we'll flush the empty spaces with an antibacterial solution.
After any required reshaping, we'll fill the pulp chamber and root canals with a special filling called gutta-percha. This rubberlike, biocompatible substance conforms easily to the shape of these inner tooth structures. The filling preserves the tooth from future infection, with the added protection of adhesive cement to seal it in.
Afterward, you may have a few days of soreness that's often manageable with mild pain relievers. You'll return for a follow-up visit and possibly a more permanent filling for the access hole. It's also likely you'll receive a permanent crown for the tooth to restore it and further protect it from future fracture.
Without this vital treatment, you could very well lose your tooth to the ravages of decay. The time and any minor discomfort you may experience are well worth the outcome.

Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
