Tooth decay can be a big problem for children's primary (baby) teeth. It doesn't take long for a tooth to become infected and the infection spread to their neighbors.
But since it will eventually give way to a permanent tooth, why not just pull a diseased primary tooth? Although that sounds sensible, there are important reasons for helping a troubled primary tooth survive to its natural end.
Current usefulness. They may not be around for long, but primary teeth serve children well while they have them. They enable a child to eat solid foods to further their physical development. They also figure prominently in speech development, which could be stunted by lost teeth.
The smile factor. Young children are also honing their social skills, and smiling is an important part of learning to fit in with family and friends. A tooth that's missing for some time, especially in the “smile zone,” could affect their smile and have an adverse effect on their social development.
Future teeth health. A primary tooth reserves the space intended for the future permanent tooth, helping to ensure the incoming tooth erupts in the right position. If it's not there, however, other teeth can drift into the space, crowding the incoming tooth out of its proper alignment.
That last reason could have the most long-term effect, causing the development of a poor bite that could require extensive orthodontic treatment. To avoid this and any other physical or social consequences accompanying its premature loss, it's worth the effort to try to protect and save a primary tooth.
Preventively, we can apply sealants on biting surfaces more prone to plaque buildup (the main cause of decay) and topical fluoride to strengthen enamel. When decay does occur, we may be able to remove it and fill the tooth, cap a tooth with a steel crown, or even use a modified root canal procedure in the case of advanced tooth decay.
The best way, however, to protect your child's primary teeth is to brush and floss them every day. Removing harmful plaque vastly reduces the risk of tooth decay. Coupled with professional dental care, your child can avoid tooth decay and get the most out of their primary teeth.

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.

Tooth enamel, to play on a phrase from Shakespeare, is made of “sterner stuff.” The strongest substance in the body, enamel can take years of biting and chewing and keep on going.
It does have one nemesis, though—mouth acid, which can soften and erode enamel’s mineral content. This is less of a concern if you have healthy saliva flow, because saliva neutralizes acid in thirty minutes to an hour after an acid attack and can also help re-mineralize the enamel. Daily brushing and flossing also help curb mouth acid by reducing the bacteria that produces it.
But as effective as saliva is at neutralizing mouth acidity, it can be overwhelmed by outside acid derived through certain foods and beverages. In the past couple of decades, at least two of these acid sources have grown in prominence: energy drinks and, believe it or not, sports drinks.
Just how acidic are they? The pH scale runs from 1 to 14, with acidity on the low end and alkalinity on the higher (7 is neutral). Tooth enamel begins dissolving below 5.5. Laboratory tests have pegged the average pH of energy drinks at 3.05 and sports drinks, 2.91.
Because of their acidity, frequent energy or sports drink consumption will bring mouth pH into the danger zone for tooth enamel. It’s even more likely if these beverages are sipped over an extended period, which can prevent saliva from getting ahead of any newly introduced acid.
Keeping your distance from these beverages is probably the safest bet. But if you do imbibe occasionally, follow these common sense tips:
- Avoid sipping the beverage over long periods—and try to limit drinking them to meal times;
- After drinking a beverage, wash your mouth out with water and wait an hour to brush to give your saliva time to neutralize any acid.
- Practice consistent, daily brushing and flossing.
Above all, keep a healthy respect for acidic foods and beverages like energy and sports drinks and don’t overuse them. Your tooth enamel will appreciate it.

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.
In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.
Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.
Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.
Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.
By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.
If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.
Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.
