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
Steven Glassman, New York, NY
“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
Carolyn Van Buskirk, New York, NY
“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
Irena Vaksman, San Francisco, CA
“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
Les Latner, Los Angeles, CA
“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. Les Latner, DDS, MAGD drles@ucla.edu ” Read more
Michael Apa, New York, NY
“Most cases will require some minor movement of the bottom teeth at the same time, however it is possible to use an upper tray only.” Read more
Marlen Martirossian, River Edge, NJ
“For the most part you do have to wear the lower Invisalign retainer for some minor bite correction.” Read more

I want to reduce my wrinkles.

Wrinkles are the creases and crevices that develop on the surface of your skin. Wrinkles are a very normal sign of aging, though they're not exactly welcome. Wrinkles often appear around the eyes, mouth, forehead, hands, and neck.

There are two kinds of wrinkles: dynamic and static. Dynamic wrinkles are caused by the movement of muscles and appear only when the muscles are contracted. For example, crow's feet may initially appear only when you smile. Static wrinkles, on the other hand, are ever-present, even when your face is at rest. Dynamic wrinkles become static over time as the muscles and skin lose the ability to snap back into shape.

Wrinkles form gradually with age as your skin loses collagen and elastin. Collagen and elastin are the essential proteins that strengthen skin. As these vital proteins weaken, your skin becomes thinner, drier, and more prone to creasing and wrinkles. Fat cells also deflate with age. While this might sound nice, shrunken fat cells…

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.

Home teeth whitening (bleaching)

Social habits, like smoking and sipping on dark beverages, can tarnish the surface of teeth, causing them to appear yellow and discolored. Home teeth whitening systems can reverse this natural wear and tear, resulting in a whiter smile.

Home bleaching kits come in the form of strips or trays, containing one of two active ingredients—either hydrogen peroxide or carbamide peroxide. Both are equally prevalent in home whitening products and produce comparable results. Learn about two of the most popular and effective home whitening systems: Crest WhiteStrips and Rembrandt FormFit.

Carbamide peroxide was the first ingredient to be used. A slightly gentler compound, carbamide appears in these products in higher concentrations. On average, home bleaching kits contain 5% hydrogen peroxide or 10% carbamide peroxide (dentists can use more than four times this amount). When exposed to water, peroxides create a chemical reaction that breaks down the pigmented elements responsible…

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…
