Before the days of easily accessible at home teeth whitening solutions, there were dental teeth whitening trays - a custom-shaped, tooth bleaching tray that was only available at your dentist's office. While the dentist created at home trays were an easy and popular way to whiten your teeth at your leisure, eventually manufacturers like Crest and AquaFresh took notice. Before long, an over the counter, at home teeth whitening tray was introduced. These became one of the easiest and most effective ways to get a brighter, whiter and more dazzling smile in the comfort of your own home, and at a fraction of the cost of a traditional dental whitening tray.
A custom fitted teeth whitening tray is the ideal solution, and can be purchased directly from your dentist. It is also the most expensive (though effective) type of tray available. A unique new hybrid solution is called a thermoforming whitening tray. These trays work by being soaked in warm water, which makes the malleable. You then press the tray onto your teeth, and when it hardens it is removed and washed in cold water. The great benefit of a thermoforming whitening tray is that it is more closely modeled to your teeth like a custom dental tray - however it's less expensive and can be used with your choice of bleaching and teeth whitening gels. One downside however is that these trays tend to leak more gel, so you'll need to hold the tray firmly in your mouth when it is in use.
Dental assisting includes a range of responsibilities including patient health, cleaning, and using dental impression trays. It's important that dentists and assistants learn how to correctly prepare a disposable impression tray before application, and also how to apply it and remove it from the patient's mouth correctly.
There are several different types of dental impression trays, and each is used for a specific purpose. It's important for dentists and dental assistants to learn about all kinds of dental trays and be able to determine which one is right for each patient. Be educated about all impression trays for teeth and their uses.
