What do a teenager with a poor bite, a senior citizen with multiple missing teeth or a middle-aged person with a teeth grinding habit all have in common? They may all depend on a dental appliance for better function or appearance.
There’s a wide variety of removable dental appliances like clear aligners or retainers for orthodontic treatment, dentures for tooth loss or night guards to minimize teeth grinding, just to name a few. But while different, they all share a common need: regular cleaning and maintenance to prevent them from triggering dental disease and to keep them functioning properly.
The first thing to remember about appliance cleaning is that it’s not the same as regular oral hygiene, especially if you have dentures. While they look like real teeth, they’re not. Toothpaste is a no-no because the abrasives in toothpaste designed for tooth enamel can scratch appliance surfaces. These microscopic scratches can develop havens for disease-causing bacteria.
Instead, use liquid dish detergent, hand soap or a specific cleaner for your appliance with a different brush from your regular toothbrush or a specialized tool for your particular appliance. Use warm but not very hot or boiling water: while heat indeed kills bacteria, the hot temperatures can warp the plastic in the appliance and distort its fit. You should also avoid bleach—while also a bacteria killer, it can fade out the gum color of appliance bases.
Be sure you exercise caution while cleaning your appliance. For example, place a towel in the sink basin so if the appliance slips from your hands it’s less likely to break hitting the soft towel rather than the hard sink. And while out of your mouth, be sure you store your appliance out of reach of small children and pets to avoid the chance of damage.
Cleaning and caring for your appliance reduces the risk of disease that might affect your gums or other natural teeth. It will also help keep your appliance working as it was designed for some time to come.
Often as children grow older, their participation in sports or similar activities increases. While generally encouraged, this greater activity does increase injury risk, especially to the mouth.
In fact, the late childhood to early adulthood demographic is the most prone portion of the population to incur dental injuries. To complicate matters, their dental development is often incomplete, posing a number of treatment obstacles for an injured tooth.
For example, the primary means for preserving an injured adult tooth is a root canal treatment: damaged or diseased tissue within the pulp, the tooth’s innermost layer, is removed and the empty chamber and root canals filled and sealed to prevent infection. But while a fully matured tooth can function without the nerves and blood vessels of the pulp, a developing tooth needs these tissues for continued tooth formation. Otherwise, tooth development can stall and cause problems later on.
The most common solution for younger teeth is to remove any damaged tooth structure without disturbing the pulp if at all possible followed by a filling. That’s contingent, though, on whether we find the pulp unexposed or undamaged—if it is, we’ll try to remove only damaged or diseased pulp tissue and leave as much healthy tissue intact as possible. To aid with healing and tissue re-growth, we may also place medicinal stimulators between the pulp and the filling.
Jaw development may also pose a challenge if the injured tooth is too far gone and must be removed. Our best choice is to replace it with a dental implant; but if we install the implant while the jaw is still growing, it may eventually appear out of place with the rest of the teeth. It’s best to postpone an implant until full jaw maturity in early adulthood.
In the meantime we could provide a temporary solution like a removable partial denture or a modified bonded bridge that won’t permanently alter nearby teeth. These methods can adequately restore the function and appearance of missing teeth until the jaw is mature enough for an implant.
While injuries with young permanent teeth do pose extra challenges, we have effective ways to address them. With the right approach, the outcome can be just as successful as with a mature tooth.

Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.
