I can choose the Invisalign tray for upper teeth only, correct? My bottom teeth are fine.
Amanda Seay, Mount Pleasant, SC
“It truly is case dependent. If your bite(occlusion) is acceptable and you are only correcting minor tooth position then it should be fine to only treat one dental arch and not both. But...the new teeth positions must be in harmony with the lower teeth to give you a balanced bite.” Read more

“Usually it's best to to use Invisalign on both arches. We chew dynamically (in motion) not Static. So even though the esthetic complain is on the upper arch, by straightening them they may knock into the lower and not fit together properly when biting and chewing. It generally also takes...” Read more

“While it is theoretically possible to only treat one arch, this is by far the exception. A better result is usually achieved if both arches are treated. Even if it may appear to you that "the lower teeth are fine", usually some movement of the lower teeth is necessary to provide the leeway for...” Read more

“Invisalign is typically done for both upper and lower teeth, even if you are only actively treating one arch. It is best to control the bite while moving the teeth, thus it is recommended to wear both upper and lowers aligners throughout treatment. ” Read more
Steven Bader, Newton Centre, MA
“It sounds like you are asking if you can choose to have Invisalign treatment for your upper teeth only. Absolutely! An evaluation with an Invisalign certified dentist will show you whether it may help to make some changes to your lower teeth to allow your upper teeth to look better. Most...” Read more

“Generally, when moving teeth in one arch (the upper arch in this case), then the teeth might not bite together properly unless the teeth on the lower arch are moved. Each patient's situation is different and needs to be evaluated by your dentist.

I want to lose weight.
It only takes three letters to describe one of the weightiest words: Fat. But not all fat is created equal.
Visceral fat is practically invisible, collecting internally around major abdominal organs. It plagues mainly sedentary individuals. Even the naturally skinny (but lazy) can be victimized by visceral fat. Subcutaneous fat is the kind most people are all too familiar with - the fat that rolls over your waistband and pools under your chin. It's pinchable, pullable, pokeable, and resides just under the skin.
Aside from looking in a mirror, excess weight is determined by calculating one's body mass index (BMI). The BMI is a formula based on height and weight, and it separates people into four categories: underweight, normal, overweight, and obese. One is typically considered obese with a BMI of 30 or higher.
Excess weight amasses over time due to decreased physical activity, changes in hormone levels, and a metabolism that slows with age, causing fat to be burned…
Thermage
Thermage reduces signs of aging, like loose skin, cellulite and wrinkles, by stimulating the body's supply of collagen - the protein that makes up 80% of the skin.
Thermage not only improves the condition of existing collagen but further stimulates the body fresh collagen, thus revitalizing and tightening the skin.
Thermage uses a kind of radiofrequency (RF) energy that passes through the skin to heat and tighten underlying tissues and increase collagen production, which in turns smooths the surface of the skin.
Radiofrequency (RF) energy is just another name for radio waves. Not only can radio carry sound, it can also transmit energy and heat. Microwaves, for example, use radio waves to heat food. Radiofrequency energy can also be used to deliver targeted heat into deep layers of body tissue without affecting the surface of the skin.
In-office teeth whitening
A white, bright smile is an important accessory for any face. But while most toothpaste includes particles of silica or aluminum oxide to grind away surface stains, they can't clear up long-term, persistent staining. Professional teeth bleaching—bleaching gel that is obtained from a dentist—can brighten discolored teeth.
There are two ingredients that can be used to bleach teeth - hydrogen peroxide and carbamide peroxide. Both compounds are oxidizing agents that break down stain-causing molecules on the teeth.
Because dentists are certified to use a more concentrated bleaching gel, professional procedures like BriteSmile and Zoom whitening can whiten teeth more quickly. By comparison, kits for do-it-yourself teeth bleaching contain only up to 5 percent hydrogen and 10 percent carbamide peroxide, whereas dentists can use 10 to 35 percent hydrogen peroxide. A higher dosage is necessary when carbamide is used, since it is slightly weaker.
Sunless tanning
Tanning can give the skin an attractive golden glow. But UVA and UVB rays from the sun can also wrinkle your skin (through breaking down elastin and collagen) and increase the likelihood of developing melanomas and other skin cancers.
The solution, for many, is sunless tanning. A sunless tan can be achieved in one of many ways and most commonly involves the application of reactive chemicals (DHA and/or erythrulos—more on them later) to the skin to give it the appearance of a suntan without actually spending time in the sun.
It's possible to temporarily color the face without chemicals - through the use of cosmetic bronzers, which are tinted powders or creams - but if you're looking for an overall glow that won't wash off right away, sunless tanning is the way to go. Keep in mind that sunless tanning does not provide any protection from the sun - it's not a "base tan."
Sunless tanners come in two main forms: lotions and spray tans. You can apply these lotions and…
