You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

Even though coronavirus lockdowns have prevented TV hosts from taping live shows, they're still giving us something to watch via virtual interviews. In the process, we're given occasional glimpses into their home life. During a Tonight Show interview with Seahawks quarterback Russell Wilson and his wife, R & B performer Ciara, Jimmy Fallon's daughter Winnie interrupted with breaking news: She had just lost a tooth.
It was an exciting and endearing moment, as well as good television. But with 70 million American kids under 18, each with about 20 primary teeth to lose, it's not an uncommon experience. Nevertheless, it's still good to be prepared if your six-year-old is on the verge of losing that first tooth.
Primary teeth may be smaller than their successors, but they're not inconsequential. Besides providing young children with the means to chew solid food and develop speech skills, primary teeth also serve as placeholders for the corresponding permanent teeth as they develop deep in the gums. That's why it's optimal for baby teeth to remain intact until they're ready to come out.
When that time comes, the tooth's roots will begin to dissolve and the tooth will gradually loosen in the socket. Looseness, though, doesn't automatically signal a baby tooth's imminent end. But come out it will, so be patient.
Then again, if your child, dreaming of a few coins from the tooth fairy, is antsy to move things along, you might feel tempted to use some old folk method for dispatching the tooth—like attaching the tooth to a door handle with string and slamming the door, or maybe using a pair of pliers (yikes!). One young fellow in an online video tied his tooth to a football with a string and let it fly with a forward pass.
Here's some advice from your dentist: Don't. Trying to pull a tooth whose root hasn't sufficiently dissolved could damage your child's gum tissues and increase the risk of infection. It could also cause needless pain.
Left alone, the tooth will normally fall out on its own. If you think, though, that it's truly on the verge (meaning it moves quite freely in the socket), you can pinch the tooth between your thumb and middle finger with a clean tissue and give it a gentle tug. If it's ready, it should pop out. If it doesn't, leave it be for another day or two before trying again.
Your child losing a tooth is an exciting moment, even if it isn't being broadcast on national television. It will be more enjoyable for everyone if you let that moment come naturally.

If a breath of crisp winter air makes you say, “Ouch!” you're not alone. According to a study published in the Journal of the American Dental Association, one of every eight people suffers from tooth sensitivity. And for those individuals, winter can be a particularly challenging time of year.
Tooth sensitivity can result when the inner part of the tooth, called dentin, is exposed. Dentin is normally protected by enamel above the gum line and cementum below, but if the protective coating is lost, then temperature, pressure and acid from food and drinks can activate the nerves inside the tooth.
If you suffer from tooth sensitivity, these tips may help:
Avoid acidic foods and beverages. It may be common sense to stay away from foods and drinks that are hot or cold enough to make you wince, but also avoid those that are acidic, as acid can erode tooth enamel and increase tooth sensitivity.
Wait an hour to brush your teeth. After consuming acidic food or beverages, give your saliva time to neutralize the acid and strengthen the enamel surface to prevent erosion.
Brush gently. Gums can recede due to over-aggressive brushing, exposing sensitive tooth roots. So brush your teeth gently with a soft-bristled toothbrush and rinse with lukewarm water.
Use toothpaste for sensitive teeth. Toothpaste that is specially formulated for sensitive teeth blocks the pores in the tooth's surface where sensitivity can occur. It may also to help to rub the toothpaste on sensitive areas.
Sometimes, however, sensitive teeth result from dental problems that need professional treatment in the form of an at-home prescription, an in-office treatment like bonding or sealants, or a procedure like a gum graft or root canal. Accordingly, here's the most important tip of all:
Schedule a dental appointment. In an exam, we can look for the cause of your tooth sensitivity so it can be treated properly. Sensitivity may result from receding gums, tooth decay, erosion of the enamel, or other dental problems, such as the following:
- Tooth-grinding. If we detect signs of a nighttime tooth grinding habit that you may not even be aware of, we may recommend a nightguard to wear while sleeping.
- A root infection. If your tooth remains sensitive 30 seconds after eating or drinking something hot or cold, the pulp inside your tooth may be damaged. You may need root canal therapy to remove the infection and stop it from spreading.
- A cracked tooth. A crack in a tooth may not be visible due to its size or location, but a compromised tooth surface can cause sensitivity and could lead to bigger problems if not treated.
Don't let tooth sensitivity get you down this winter. Come see us so we can discuss the right treatment for you.
