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.

Thousands of years ago, our ancestors could only expect to live between 30 and 40 years. But steady improvements in lifestyle and medical care have increased human life expectancy to almost 80 years.
Although a welcome development, it does raise a question: Are our teeth up to the added years? Even though quite resilient, it's natural for teeth to wear after years and tens of thousands of meals biting and chewing.
Fortunately, there have also been phenomenal advances in dental restorations that can effectively replace teeth we lose along the way. Even so, the most advanced artificial replacements can't restore the full benefit of natural teeth to oral and general health. The ideal goal is to preserve and protect our natural teeth for as long as possible.
Here are 4 areas worthy of your attention in protecting your teeth throughout your lifetime.
Dental disease. Tooth decay and periodontal (gum) disease are the top causes for poor dental health and tooth loss. They're caused by bacteria living and feeding primarily in dental plaque, a thin biofilm on tooth surfaces. Brushing and flossing daily, along with regular dental cleanings, removes this disease-causing plaque. You should also seek treatment as soon as possible at the first sign of dental disease.
Bite correction. A poor bite is more than a smile problem: Teeth out of alignment and not engaging normally with their counterparts on the other jaw may increase tooth wear and make hygiene more difficult to perform. Orthodontic treatment, even if undertaken later in life, can help maintain your teeth's long-term health and longevity.
Bad habits. Your teeth are tough, but not indestructible. Protect them by avoiding harmful habits or practices like crunching ice, gnawing on pencils, nails or other hard objects, cracking open nuts or using your teeth as tools. Not engaging in these kinds of habits will help reduce wear and help you also avoid chipping and fractures.
Teeth grinding. Involuntarily clenching or grinding your teeth, often while sleeping, can accelerate dental wear. If you suspect you have this habit, take steps first to deal with stress, the number one cause of adult teeth grinding. Your dentist can also fashion a mouth guard that prevents your teeth from making solid contact with each other and thus help reduce wearing to your teeth.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.

Parents have been dealing with their children's teething pain for as long as parents and children have been around. Along the way, the human race has developed different ways to ease the discomfort of this natural process of dental development. While most are good, common-sense measures, one in particular needs to be avoided at all costs—applying topical oral products to the gums containing Benzocaine.
Benzocaine is a topical anesthetic often found in oral products like Anbesol, Orajel or Topex to help ease tooth pain or sensitivity. The agent can be found in gel, spray, ointment or lozenge products sold over-the-counter. As an analgesic, it's considered relatively safe for adults to use.
But that's not the case with infants or younger children. Researchers have found a link between Benzocaine and methemoglobinemia, a potentially fatal blood condition. Methemoglobinemia elevates the amount of a hemoglobin-like protein called methemoglobin, which in high concentrations can lower oxygen levels being transported to the body's cells through the bloodstream.
Because of their smaller anatomy and organ systems, younger children can have severe reactions to increases in methemoglobin, which can range from shortness of breath or fatigue to seizures, coma or even death. That's why you should never use products with Benzocaine or similar numbing agents to ease teething pain. Instead, follow these common sense practices:
- Give your child chilled rubber teething rings, wet washcloths or pacifiers to chew or gnaw on. The combination of cold temperatures and pressure from biting on them will help ease the pain. Just be sure the item isn't frozen, which could cause frost burns to soft tissues.
- For temporary relief from soreness, gently massage your baby's gums with a clean, bare finger or with it wrapped in a clean, wet cloth. The massaging action helps counteract the pressure of the incoming tooth.
- For intense episodes of teething discomfort, ask your healthcare provider about using an over-the-counter pain reliever like acetaminophen or ibuprofen. Be sure you use only the recommended dose size for your child's age.
Teething is in many ways like a storm—it too shall pass. Be sure you're helping your baby weather it safely.
Being a parent can be a rewarding role. But it's also hard work, especially the effort required in keeping children healthy. In that respect, there's one area you don't want to overlook—their dental health.
Taking care of their teeth and gums has two aspects: their current state of dental health and their ongoing development that impacts future health. Fortunately, you can address both the present and the future by focusing on the following areas.
Prioritizing oral hygiene. From the moment your child is born, you'll want to practice daily oral hygiene to keep their teeth and gums clean of disease-causing bacterial plaque. This starts even before teeth erupt—simply wipe their gums with a clean wet cloth after feeding. As teeth emerge, begin brushing each one with a small amount of toothpaste. Around your child's second birthday, start training them to brush and floss on their own.
Limit their sugar intake. The biggest threat to your child's teeth is tooth decay, which is caused by bacteria. These bacteria multiply when they have plenty of sugar available in the mouth, one of their primary food sources. It's important then to reduce the sugar they eat and limit it to mealtimes if possible. Also avoid sending them to bed with a bottle filled with sweetened liquids, including juices and even formula.
Visit the dentist. You're not in this alone—your dentist is your partner for keeping your child's teeth healthy and developing properly. So, begin regular visits when your child's first teeth appear (no later than their first birthday). You should also consider having your child undergo an orthodontic evaluation around age 6 to make sure their bite is developing properly.
Practice oral safety. Over half the dental injuries in children under 7 occur in home settings around furniture. As your child is learning to walk, be aware of things in your home environment like tables and chairs, or hard objects they can place in their mouths. Take action then to move these items or restrict your child's access to them.
Good habits in each of these areas can make it easier to keep your child's teeth and gums healthy and on the right developmental track. That means good dental health today that could carry on into adulthood.
