Teeth Whitening Trays

At-home teeth whitening treatments come with teeth whitening trays. There is a huge difference between the teeth whitening trays that come with a professional at-home whitening kit you get from a cosmetic dentist and the kits you can get over the counter. The main difference is that the professional whitening kits come with custom made trays that are specifically made for each patient's mouth.
Teeth whitening trays are necessary for at home whitening. The trays are resonsible for holding the teeth whitening gel in place on the teeth. Without the trays, the gel would slip off the teeth and not be given ample time to whiten.
The custom made trays that you get from your cosmetic dentist are much more effective in whitening teeth than the one size fits all trays you get from over the counter teeth whitening kits. The custom made trays come with whitening reservoirs that fit the exact contour of your teeth. The whitening reservoirs are important for holding the whitening gel in the exact position necessary for whitening teeth.
The whitening reservoirs are tiny spaces between the teeth and the tray. The gel slides in place in these tiny spaces and stays put evenly dispersed over the teeth. The gel does not have a chance to move so the whitening results are fantastic and even.
Creating Custom Made Teeth Whitening Trays
Your cosmetic dentist will create a mold of your upper and lower teeth at a teeth whitening consultation. The mold is sent to a special dental laboratory where a cast is made form the mold. A dental laboratory technician will apply a very thin layer of plastic to each individual tooth that takes the place of the whitening gel on the teeth.
After the thin layer of plastic is applied to the cast, the technician places a heated plastic sheet onto the cast and over the thin plastic layer to create the whitening trays. The thin plastic layer holds the plastic sheet just far enough away to leave room between the teeth and the trays. This room is the whitening reservoir. Once the plastic sheet is formed and cooled, the technician removes the plastic trays and sends the teeth whitening trays to your cosmetic dentist. Your cosmetic dentist will make any adjustments necessary to the trays so they fit in your mouth perfectly.
