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.

As a saying, “Necessity is the mother of invention” is no more appropriate than when you have something caught between your teeth. And humans, as inventive and creative as we are, have used a weird assortment of items—usually within arms' reach—to dislodge a pesky bit of food.
According to a recent survey, more than three-fourths of Americans admit to using a number of “tools” to clean between teeth including twigs, nails (the finger and toe variety), business cards or (shudder!) screwdrivers. And it's one thing to do this alone, but among dinner companions and other folk it's a definite faux pas.
Usually, it's smarter and more economical if you can use a particular tool for many different applications. But when it comes to your teeth, you should definitely go with a “unitasker” designed specifically for the job: dental floss. It's not only the safest item you can use to clean your teeth, it's specifically designed for that purpose, especially to remove disease-causing plaque from between teeth.
Of course, the reason many of us use alternate items for cleaning between teeth is that they're the closest ones at hand. You can remedy this by keeping a small spool (or a short length) of dental floss or floss picks handy for those moments you encounter a wedged piece of food. In a pinch, you can use a rounded toothpick (better for your gums than the flat variety).
At home if you find flossing difficult, consider using a water flosser. This handheld device emits a pulsating stream of pressurized water that loosens and flushes away plaque and bits of food remnant. It's ideal for people who have a hard time maneuvering floss or who wear braces, which can block regular floss thread from accessing between teeth as fully as possible.
In any case, use the other “tools” at hand for whatever they're intended. When it comes to what's best for your teeth, use floss to keep the in-between clear and clean.
Tooth decay doesn't occur out of thin air, but is the end result of bacteria feeding on sugar, multiplying and producing acid. High acidity erodes tooth enamel and creates an environment for cavity development.
Modern dentistry can effectively treat cavities and often save the tooth from further damage. But you don't have to wait: You can reduce your chances of cavities by managing risk factors that contribute to decay.
Here are 4 top risk factors for tooth decay and what you can do about them.
Poor saliva flow. Saliva neutralizes acid and helps restore minerals to enamel after acid contact. But your enamel may not have full protection against acid if you have diminished saliva flow, often due to certain medications. You can help increase your saliva by consulting with your doctor about drug alternatives, drinking more water or using a saliva boosting product. Smoking can also inhibit saliva, so consider quitting if you smoke.
Eating habits. High sugar content in your diet can increase bacterial growth and acid production. Reducing your overall sugar consumption, therefore, can reduce your risk of decay. Continuous snacking can also increase your decay risk, preventing saliva from bringing your mouth back to its normal neutral pH. Instead, limit your snack periods to just a few times a day, or reserve all your eating for mealtimes.
Dental plaque. Daily eating creates a filmy buildup on the teeth called dental plaque. If not removed, plaque can then harden into a calcified form called calculus, an ideal haven for bacteria. You can help curtail this accumulation by thoroughly brushing and flossing daily, followed by dental cleanings at least every six months. These combined hygiene practices can drastically reduce your cavity risk.
Your genetics. Researchers have identified up to 50 specific genes that can influence the risk for cavities. As a result, individuals with similar dietary and hygiene practices can have vastly different experiences with tooth decay. Besides continuing good lifestyle habits, the best way to manage a genetic disposition for dental disease is not to neglect ongoing professional dental care.
