Question: What oral health issue do teenagers who wear orthodontic retainers and older folks who wear dentures have in common?
Answer: Both need to pay particular attention to cleaning their oral appliances.
The same goes for anyone who wears a nightguard to control tooth grinding, a mouthguard to protect teeth while playing sports, or a clear aligner for orthodontic treatment. Yet many people aren’t sure how to properly clean their appliances — so here are a few handy tips:
- Use toothpaste on your appliance — the ingredients in toothpaste, which are designed to polish the hard enamel of your teeth, are too abrasive for the soft plastic of oral appliances, and will cause scratches.
- Boil your appliance, or use bleach to clean it — both will end up breaking down and destroying the appliance. Don’t even use very hot water, as it can deform the plastic and make the appliance useless.
- Leave your appliance out on the nightstand, or anywhere else — pets and small children have been known to find (and destroy) oral appliances left lying around. Instead, store it properly in its special case.
- Use liquid dish detergent or hand soap to clean your appliance. A little mild soap plus warm water will do a great cleaning job. While you’re at it, get a brush just for the appliance — because, while it’s fine for plastic, you don’t want to brush your teeth with soap!
- Put a towel in the sink basin when you clean your appliance. Soapy appliances (especially dentures) can be slippery, and can be damaged by dropping — and that’s an expensive mishap.
- Consider investing in an ultrasonic cleaner. These inexpensive countertop devices are an excellent way to get the tiny ridges and crevices of your appliance really clean.
Whether you rely on dentures for everyday use, or just need to wear a retainer for a period of time, your oral appliance serves an important function. It may also represent a significant investment. That’s why it’s worthwhile to spend a few minutes each day giving these important items the care they need.
When you floss (you do floss, right?), you probably notice a sticky, yellowish substance called plaque stuck to the thread. This thin film of tiny food particles and bacteria is the reason you floss and brush in the first place: Because it's the main trigger for tooth decay and gum disease, removing it decreases your risk for disease.
But this isn't the only form of plaque you should be concerned about. That same sticky substance can also interact with your saliva and harden into what's commonly known as tartar. Dentists, however, have a different term: They refer to these calcified deposits as calculus. And it's just as much a source of disease as its softer counterpart.
You might have noticed that this form of plaque has the same name as an advanced type of mathematics. Although dental calculus has little in common with algebra's cousin, both terms trace their origins back to the same linguistic source. The word “calculus” in Latin means “small stone;” it became associated with math because stone pebbles were once used by merchants long ago to calculate sales and trades.
The term became associated with the substance on your teeth because the hardened plaque deposits resemble tiny stones or minerals—and they can be “as hard as a rock” to remove. In fact, because they adhere so firmly it's virtually impossible to remove calculus deposits with brushing or flossing alone. To effectively eliminate calculus from tooth surfaces (including under the gum line) requires the skills and special dental tools of dentists or dental hygienists.
That's why we recommend a minimum of two dental cleanings a year to remove any calculus buildup, as well as any pre-calcified plaque you might have missed with daily hygiene. Reducing both plaque and calculus on your teeth fully minimizes your risk of dental disease. What's more, removing the yellowish substance may also brighten your smile.
That's not to say daily brushing and flossing aren't important. By removing the bulk of plaque buildup, you reduce the amount that eventually becomes calculus. In other words, it takes both a daily oral hygiene practice and regular dental visits to keep your teeth healthy and beautiful.
We Americans love our sports, whether as participants or spectators. But there's also a downside to contact sports like soccer, football or basketball: a higher risk of injury, particularly to the mouth and face. One of the most severe of these is a knocked out tooth.
Fortunately, that doesn't necessarily mean it's lost: The tooth can be reinserted into the empty socket and eventually return to normal functionality. But it must be done as soon as possible after injury. The more time elapses, the lower the chances of long-term survival.
That's because of how teeth are held in place in the jaw, secured by an elastic, fibrous tissue known as the periodontal ligament. When a tooth is knocked out some of the ligament's periodontal cells remain on the tooth's root. If these cells are alive when the tooth is reinserted, they can regenerate and reestablish attachment between the ligament and the tooth.
Eventually, though, the cells can dry out and die. If that has already happened before reinsertion, the tooth's root will fuse instead with the underlying bone. The tooth may survive for a short time, but its roots can eventually dissolve and the tooth will be lost.
Your window of opportunity for taking advantage of these live periodontal cells is only 5-20 minutes with the best chances in those earlier minutes. You should, therefore, take these steps immediately after an injury:
- Find the tooth, hold it by the crown (not the root end), and rinse off any debris with clean water;
- Reinsert the root end into the empty socket with firm pressure;
- Place clean gauze or cloth in the person's mouth between the tooth and the other jaw, and ask them to bite down gently and hold their bite;
- Seek dental or emergency medical care immediately;
- If you're unable to reinsert the tooth, place it quickly in a container with milk and see a dentist immediately.
You can also obtain an Android or IOS smartphone app developed by the International Association of Dental Traumatology called ToothSOS, which will guide you through this process, as well as for other dental emergencies. The quicker you act, the better the chances that the injured person's knocked out tooth can be rescued.
