Whether you live in the snow belt or the sunny south, the winter season often means a change in the weather. In many places, the sun isn't as strong and cooler temperatures bring relief from the summer's heat. Yet even though it may be chillier outside, your body's need for hydration is the same as it was in the summer—and a lack of proper hydration can be bad news for your oral hygiene.
Everyone knows we need to drink plenty of water every day to stay healthy. It's important for good oral hygiene because water is the major component of saliva, which fights bacteria and helps neutralize the acids that cause tooth decay. Water also keeps the soft tissues of the mouth moist and healthy, and helps fight bad breath. In many communities tap water is fluoridated, which offers proven protection against cavities.
But in the middle of winter, fewer people carry around bottles of cold water for refreshment—and that's a shame, because we need it just as much! While indoor (and outdoor) air is often drier in winter, your body continues to lose water in the same ways. And if you keep up a healthy exercise routine (like jogging, snow sports or backyard fun and games), you still need plenty of hydration. An ice-cold glass of water may not be as appealing in January as in July…but it's just as important.
Of course, the water you drink doesn't have to be freezing cold to do its job. Hot tea (especially herbal tea) can be a healthy option for wintertime hydration. So is plain water without ice. Fruits and vegetables also contain lots of water, plus vitamins, fiber, and many more substances that are good for your body.
But there are some drinks you should avoid—or at least take in moderation. Regularly drinking coffee and tea can stain your teeth, and excessive caffeine may have negative health effects. Consuming alcoholic beverages can cause dry mouth, and may increase the risk of oral cancers. And, of course, drinks that contain sugar (including soda, some juices, and many coffee and hot chocolate beverages) are linked not only to tooth decay, but to other health problems as well.
And whatever the season, don't forget to come in to the dental office for regular checkups and cleanings. We can remove the sticky tartar that clings to your teeth and may cause tooth decay and other problems. We will also perform a complete dental exam, evaluate your oral health and help resolve small problems before they turn into big headaches (or toothaches). Working together, we can help you enjoy the benefits of good oral hygiene all though the year.

We've known for decades that fluoride strengthens tooth enamel and lowers the risk for decay. And while adding it to toothpaste and drinking water are the more common ways for getting it into the body, an increasingly popular way—especially for children—is to apply fluoride directly to the teeth.
But is topical fluoride really worth the effort and expense? And, are there any side effects to treating teeth this way?
As to the first question, researchers have performed numerous studies measuring fluoride's effectiveness for preventing tooth decay. The Cochrane Oral Health Research Group recently reviewed studies on topical fluoride applications involving nearly 10,000 children and adolescents between the ages of 2 and 15. The combined average for all the studies showed a 28% reduction in decayed teeth for patients who received topical fluoride compared to those who didn't.
This was especially true for children at high risk for decay: directly applying fluoride gels, foams or varnishes to teeth reduces that risk substantially. But there are also side effects to this application. Fluoride in general has only one known safety concern, a condition known as fluorosis. Too much fluoride over time can cause heavy discoloration of the teeth. This does not affect the health of the teeth, but it can look unattractive and require cosmetic treatment to reduce its effect.
There's little to no risk for fluorosis with the controlled treatments offered by dentists; the fluoride solution remains on the teeth no more than a few minutes. But there is a possible side effect during treatment due to the relatively high dose of fluoride used. If the patient accidentally swallows some of the solution, the concentration of fluoride can cause stomach upset, vomiting or headaches.
Dentists minimize the chances for this by usually using the more difficult to swallow varnish form of topical fluoride on younger patients, and using trays or other barrier devices to isolate the fluoride solution from the rest of the mouth. Under professional supervision, it's rare for an accidental ingestion to occur.
The risks for these side effects are quite low, and the benefits of topical fluoride for reducing the chances for decay can more than outweigh them. Fluoride applications are one of many ways we can protect your child's current and future dental health.

As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.
This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.
An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.
Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.
But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.
One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.
Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.
