If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.

Your child's oral development generates considerable changes during their "growing up" years. There are a number of things you can do to help support their development—but also things you shouldn't.
Here are 4 things not to do if you want your child to develop healthy teeth and gums.
Neglect daily oral hygiene. To set the best long-term course for optimum oral health, begin cleaning the inside of your child's mouth even before they have teeth. Simply use a clean wet washcloth to wipe their gums after feeding to reduce bacterial growth. Once you begin seeing teeth, start brushing them every day with just a smear of toothpaste; at about age 2 you can increase that to a pea-sized amount. And don't forget to teach them when they're ready to brush and floss on their own!
Allow unlimited sugar consumption. Besides the effect it has on overall health, sugar is also a prime food source for disease-causing oral bacteria. You can reduce the sugar available for bacterial growth by avoiding sugary snacks and limiting sweet foods to meal times. Less sugar means less bacterial growth—and a lower risk of tooth decay for your child.
Put them to bed with a sugary liquid-filled bottle. Although a bedtime bottle may help calm your baby to sleep, it could also increase their risk of tooth decay. Allowing them to sip on sugar-filled liquids like juice, milk, formula or even breast milk encourages bacterial growth. Bacteria in turn produce acid, which can dissolve the minerals in enamel and open the door to tooth decay. Sipping through the night also deprives saliva of adequate time to neutralize acid.
Wait on dental visits until they're older. Dental and pediatric associations all recommend first taking your child to the dentist sooner rather than later—by their first birthday. Starting dental visits early will help you stay ahead of any developing tooth decay or other oral problems. And just as important, your child will have an easier time "warming up" to the dental office environment at a younger age than if you wait. Dental visit anxiety, on the other hand, could continue into adulthood and interfere with regular dental care.

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.

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.
The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.
Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.
Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.
After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.
Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

For most of us, brushing and flossing is a routine part of daily life. But has it become such a routine that you may not be getting the most out of your daily regimen?
First, let's be clear about what you're trying to accomplish with these two important hygiene tasks, which is to remove as much accumulated dental plaque as possible. This thin film of bacteria and food particles is the primary cause for both tooth decay and periodontal (gum) disease.
So how can you tell if you're effectively cleaning dental plaque from your teeth? Here are 4 ways to check your brushing and flossing skills.
The tongue test. Move your tongue across the surface of your teeth, especially at the gum line, immediately after brushing and flossing. "Plaque-free" teeth will feel smooth and slick. If you feel any grittiness, though, you may be missing some plaque.
Floss check. For a similar effect after your daily hygiene take a fresh piece of floss and run it up and down your teeth. If the teeth are clean and you are using un-waxed floss, the floss should "squeak" as you move it up and down.
Disclosing agents. You can also occasionally use a plaque disclosing agent. This product contains a solution you apply to your teeth after brushing and flossing that will dye any leftover plaque a specific color. Disclosing agents are handy for uncovering specific areas that require more of your future hygiene attention. And don't worry—the dye is temporary and will fade quickly.
Dental visits. For the ultimate test, visit your dentist at least twice a year. Not only can dental cleanings remove hard to reach plaque and calculus (hardened tartar), but your dentist or hygienist can evaluate how well you've been doing. Consider it your "final exam" for oral hygiene!
Be sure to also ask your dental provider for tips and training in better brushing and flossing. Becoming more effective at these critical tasks helps ensure you're keeping your teeth and gums free of disease.
