Is there some kind of temporary dental appliance that gives the illusion of straighter, whiter teeth? It fits over your teeth like a mouth guard would. What is something like that called? Is it expensive? Does it take a long time to be fitted for such a device, and does it hurt?

Dear Alan,

The dental apparatus you are referring to is called a “Snap-On Smile”, and it fits snuggly over your existing teeth. Such a device is used sometimes for a big event like a wedding, or by actors in the theater. Though it is not durable, it can improve your smile nicely for a short time. A Snap-On Smile is considered a very temporary smile makeover, and should not be confused with porcelain veneers or crowns.

It probably takes at least two weeks, maybe a little more, to complete the entire process to get a Snap-On Smile. A dentist will make a model of your teeth, which is then sent to a dental lab in New York where the appliances are manufactured. Your Snap-On Smile should be shipped to you about two weeks after the lab receives the model from your dentist.

When you receive your Snap-On Smile, no preparation is necessary for your teeth—the appliance just snaps into place. Expect the appliance to make your teeth look bulkier and larger, and remember that it needs to be cleaned after each time you eat.

We strongly recommend that you consult an expert cosmetic dentist to help you acquire such an appliance. He or she will help you get the best results.
