If you are considering having your teeth straightened, for cosmetic or other reasons, the idea of using clear aligners rather than traditional braces may be appealing.
Here are the answers to some frequently asked questions about clear aligners.
What are clear aligners?
Clear aligners are clear removable custom fitted “trays” that gradually straighten teeth. Used sequentially, each individual tray is slightly different from the one before and is worn every day for two weeks before going on to the next one in the series. This slowly moves your teeth to a new position.
How are they made?
The trays are computer-generated, based on impressions and models of your mouth combined with the knowledge of growth, development of teeth and jaws, and most importantly how and why teeth move.
How long does this treatment take?
By wearing clear aligners for at least 20 hours per day for two weeks before changing to the next tray in the sequence, treatment time can range from six months to two years depending on your individual situation.
Can children wear clear aligners?
Clear aligners are generally used for adults who have all their teeth and when jaw growth is complete, but can be used for younger people depending upon the extent and severity of their situation.
What situations can clear aligners be used for?
Clear aligners can realign or straighten teeth, close mild spaces, treat elongated teeth and tip teeth into better position. They are usually recommended for correcting mild to moderate crowding of teeth, particularly if your back teeth already fit together properly.
When are clear aligners probably not the right choice?
If you have a bad bite (your back teeth do not fit together well), or if you have a severe overbite or underbite, traditional braces are probably a better choice for treatment. If your teeth are severely crowded, or if your situation is complex, clear aligners will probably not be the right treatment choice.
How do you decide whether clear aligners are right for you?
An orthodontic assessment of your individual situation must be performed by our office.
What is considered in the assessment?
The assessment includes specialized x-rays of your teeth, jaws and skull, along with photos, impressions, and models of your bite.

Lashinda Demus holds the U.S record in the 400 meter hurdles, with a time of 52.47 seconds, the third fastest ever recorded. While her twin 5-year-old boys cheered her on, she brought home a silver medal from the 2012 London Olympics. But when it comes to her full set of upper and lower braces, there's no silver to be seen!
Demus is a top-ranked competitor, a wife and a mom — and an adult who is currently in orthodontic treatment. With her orthodontist's approval, she chose clear ceramic braces. These are just one of the treatment options available to adult patients, many of whom prefer a less noticeable style of orthodontic appliance.
As many as three-quarters of adults are thought to have some form of orthodontic problem. Common issues include teeth that are crowded too closely together, or ones that have drifted too far apart after an extraction or other tooth loss. It is believed that straightened teeth are easier to clean and better for chewing — they can also improve an adult's social life, and even his or her career prospects!
Some grown-ups may hesitate to consider orthodontic treatment because they remember the “railroad tracks” they saw in junior high school. In fact, there have been many changes in orthodontic appliances in the past few years. Two popular choices for adults are colorless braces (the kind Demus wears) and clear orthodontic aligners.
Colorless ceramic braces are made of high-tech composite materials. They resist staining, and are less noticeable because their translucent appearance blends with the teeth. Often, a single wire is the only part that's plainly visible. Sometimes it's even possible to place them on the lingual (tongue) side of the teeth.
Clear aligners are an alternative to braces that are available to adults and teens. Instead of wires and attachments, these consist of a series of transparent, removable trays that are placed over the teeth and worn 20 hours per day. Over a period of six months to two years, the teeth are gradually straightened as you progress from one computer-designed tray to the next. Best of all, you can remove the trays completely to clean your teeth, and for important occasions.
Which one is right for you? It depends. While aligners have been successful in treating mild to moderate spacing issues, more difficult problems with the bite may require a more traditional form of braces. Also, there are a few health problems which might need to be attended to before orthodontic treatment is begun. The best way to learn about your options is to come in for a consultation. But remember: if you want a better smile, it's never too late.

Think you already know all about dentures? Answer the following questions, and see whether your understanding of false teeth is more true than false.
True or False: About one-quarter of the U.S. population has none of their own teeth left by the age of 65.
The technical term for the complete loss of all permanent teeth is edentulism, and it's a big issue, affecting 26% of adults between 65 and 74 years of age. Without treatment, many individuals not only suffer a reduced quality of life, but also risk nutritional problems and systemic health disorders. Dentures are a reliable and affordable way to replace their missing teeth.
True or False: Tooth loss has nothing to do with bone loss.
Far from being a fixed, rigid substance, bone is actually growing and changing constantly. In order for it to stay healthy, bone needs constant stimulus. For the alveolar bones of the jaw, this stimulus comes from the teeth; when they are gone, the stimulus goes too, and the bone resorbs or melts away. The missing bone mass can cause changes in facial features, difficulties with eating, speech problems and other undesirable effects.
True or False: Once the teeth are gone, there is little that can be done to mitigate bone loss.
While a certain amount of bone loss is unavoidable, it can be minimized. The techniques of bone grafting may be used to create a “scaffold” on which the body can restore its own bone tissue. Bone loss can also be limited by retaining the roots of teeth that had previous root canal treatment, even when the crowns must be removed. Perhaps the best way to limit long-term bone loss is the use of dental implants, which restores function and prevents excessive resorption from tooth loss. When tooth loss is inevitable, a pre-planned transition to dentures offers the opportunity to retain as much bone as possible, and avoid future problems.
True or False: There are many options available to make wearing dentures a fully functional and comfortable experience.
Fabricating prosthetic teeth is a blend of science and art. Not only must the appearance of the teeth and gums be made to look natural, but the fit has to be exact and the bite must be balanced. After a little practice, most people subconsciously adapt to the slightly different muscular movements required when wearing dentures. For those few who have difficulty, hybrid forms of implant-supported dentures may offer an alternative. In all cases, developing a partnership of trust between a skilled clinician and an informed patient is the best way to ensure that the experience will be a success.

Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.
2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.
3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.
4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.
5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.
6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.
8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.
9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.
10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
