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.

Periodontal (gum) disease is mainly caused by bacterial plaque built up on tooth surfaces due to ineffective oral hygiene. For most cases, treatment that includes plaque and calculus (tartar or calcified plaque) removal and renewed daily hygiene is highly effective in stopping the disease and restoring health to affected gum tissues.
However, you might have additional health factors that may make it more difficult to bring the disease under control. If your case is extreme, even the most in-depth treatment may only buy time before some or all of your teeth are eventually lost.
Genetics. Because of your genetic makeup, you could have a low resistance to gum disease and are more susceptible to it than other people. Additionally, if you have thin gum tissues, also an inherited trait, you could be more prone to receding gums as a result of gum disease.
Certain bacteria. Our mouths are home to millions of bacteria derived from hundreds of strains, of which only a few are responsible for gum disease. It’s possible your body’s immune system may find it difficult to control a particular disease-causing strain, regardless of your diligence in oral care.
Stress. Chronic stress, brought on by difficult life situations or experiences, can have a harmful effect on your body’s immune system and cause you to be more susceptible to gum disease. Studies have shown that as stress levels increase the breakdown of gum tissues (along with their detachment from teeth) may also increase.
Disease advancement. Gum disease can be an aggressive infection that can gain a foothold well before diagnosis. It’s possible, then, that by the time we begin intervention the disease has already caused a great deal of damage. While we may be able to repair much of it, it’s possible some teeth may not be salvageable.
While you can’t change genetic makeup or bacterial sensitivity, you can slow the disease progression and extend the life of your teeth with consistent daily hygiene, regular cleanings and checkups, and watching for bleeding, swollen gums and other signs of disease. Although these additional risk factors may make it difficult to save your teeth in the long-run, you may be able to gain enough time to prepare emotionally and financially for dental implants or a similar restoration.

Our nerves serve a vital purpose, alerting us to bodily discomfort, injury or disease — we couldn’t remain in good health for long without them. But when they malfunction due to genetics or disease, they can themselves become a source of pain and discomfort.
One such nerve disorder that affects the face is known as trigeminal neuralgia (TN) or tic douloureaux (from the French for “painful”). The nerves in question are the trigeminal, a pair that travel up from the brain stem through the skull into each side of the face where they each branch into the upper, middle and lower parts of the face and jaw. The pain can radiate from one or more of these branches.
TN is characterized by recurring episodes of brief but severe pain with accompanying muscle spasms. It may begin as a short twinge recurring over weeks, months or years before becoming increasingly painful. The slightest actions can trigger a painful episode: chewing, speaking, shaving or even the wind blowing on your face.
While it may be hard to determine its exact cause, it often seems to result from an artery or vein pressing on the nerve, causing it to signal pain at the slightest stimulation and then failing to stop transmitting when the stimulation is removed. It’s also associated with other inflammatory disorders like multiple sclerosis where the protective insulation around a nerve is damaged.
Before receiving treatment you should undergo a complete examination to rule out any other facial pain causes like temporomandibular (jaw joint) disorders or a dental abscess. You may also need to undergo a neurological examination and possible MRI imaging to pinpoint the exact cause, like a tumor or blood vessel pressing on the nerve.
Although the condition may not be curable, there are several effective management treatments. The more conservative approaches usually involve medications to block the nerve’s pain signals or decrease its abnormal firing. If this isn’t sufficient to diminish symptoms, there are surgical options: passing a thin needle through the nerve to selectively prevent fibers from firing, or moving aside a blood vessel pressing on it. High-dose targeted radiation may also be effective, especially with older patients.
The best treatment approach will depend on the exact cause, your age and overall health. Whatever the approach, you can gain significant relief from the pain of TN.
On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

The arrival of your child’s first set of teeth is a natural and expected process. But that doesn’t mean this period of development, commonly known as teething, is an easy time: your baby will endure a fair amount of discomfort, and you, perhaps, a bit of anxiety.
Knowing the facts about teething can help you reduce your child’s discomfort — as well as your own concern — to a minimum. Here are a few things you need to know.
Teething duration varies from child to child. Most children’s teeth begin to erupt (appear in the mouth) between six and nine months of age — however, some children may begin at three months and some as late as a year. The full eruption sequence is usually complete by age 3.
Symptoms and their intensity may also vary. As teeth gradually break through the gum line, your baby will exhibit some or all normal teething symptoms like gum swelling, drooling and chin rash (from increased saliva flow), biting or gnawing, ear rubbing, or irritability. You may also notice behavior changes like decreased appetite or disrupted sleep. These symptoms may be a minimal bother during some teething episodes, while at other times the pain and discomfort may seem intense. Symptoms tend to increase about four days before a tooth emerges through the gums and about three days afterward.
Diarrhea, rashes or fever aren’t normal. These symptoms indicate some other sickness or condition, which can easily be masked during a teething episode. If your child exhibits any of these symptoms you should call us for an exam to rule out a more serious issue.
Keep things cool to reduce discomfort. There are a few things you can do to reduce your child’s discomfort during a teething episode. Let your child chew on chilled (but not frozen) soft items like teething rings, wet washcloths or pacifiers to reduce swelling and pain. Gum massage with your clean finger may help counteract the pressure from the erupting tooth. And, if your doctor advises it, pain relievers in the proper dosage may also help alleviate discomfort. On the other hand, don’t use rubbing alcohol to soothe painful gums, or products with the numbing agent Benzocaine in children younger than two unless advised by a healthcare professional.
