Having a beautiful, white smile is something many people hope to achieve. Unfortunately, your teeth can get discoloured and stained over time from daily habits, the food and drinks you consume, and the natural aging process. Luckily, there are some professional teeth whitening procedures that have proven to be very effective. One of them is tray whitening, which combines whitening gel with trays to be placed over your teeth. Here are some benefits of choosing professional tray whitening over the alternative whitening treatments. 

The Trays Are Custom-Made

One of the major benefits of tray whitening systems over the whitening systems you use at home is the fact that these trays are custom-made. You will first visit your dentist to have impressions made of your teeth. These impressions are then sent to a dental lab to create the trays, which can take up to a couple weeks. You then return to the dentist to collect the trays and whitening gel. Your dentist will likely show you how to put in the trays in the office, completing the first treatment during that session. Since the trays are custom-fit for your teeth, the whitening is more evenly distributed. When you get at-home trays, they are standard sizes so you might have areas where your teeth are less white than other areas since they don't fit snugly over your teeth.

You Can Use the Trays Multiple Times

Another advantage to professional tray whitening systems is that these trays can be used multiple times. This is unlike laser whitening, which is a single procedure done in the dental office. Your trays will be used as many times as you like, so if in a few months you want a touch-up, you don't need to return to your dentist. This can help save you money and time in the long run. Even if the trays end up being more expensive in the beginning, you definitely get your investment back if you keep reusing them. The only time you should need to return to the dentist is to get more whitening gel or if your teeth shift and need new trays to be created. 

The Whitening is Done at Home

If you don't feel comfortable being in the dental chair for a teeth whitening procedure, you don't need to worry about it with tray whitening. You are only in the chair when getting your trays so the dentist can show you how to use them properly. After that first session, you are told to repeat the process multiple times over several days while at home. You can do this at your convenience, watching television or cooking dinner while wearing the trays. This also helps you to control how white your teeth get, as you keep using them until you are happy with the shade of your teeth.
