Tray method involves taking impressions, from which laboratory fabricated custom vinyl trays are made. A carbamide peroxide gel is placed in these trays, and it must be worn for about 3 hours per day, or overnight. The entire process takes 3 to 4 weeks of daily use. Three different strengths of gel may be used, however the higher the strength the greater the likelihood of teeth sensitivity. The tray method is recommended for badly stained teeth, such as tetracycline damage. It may take several months of use to see significant color improvement. For maintenance of whitened teeth the trays should be used once every four months.
The end results whether using trays at home or doing Zoom! are about the same. The cost of the tray method is about half compared to Zoom! and there is usually less post-treatment sensitivity.
VENEERS & BONDING
Veneer is a dental procedure in which a covering is placed over the visible area of an imperfect tooth. Veneers are usually applied to the front side of top six middle teeth, which are highly visible while talking and smiling.
The procedure can be direct or indirect. In direct technique a composite resin material is placed on the outside of the tooth using bonding. The indirect technique involves two appointments, because your veneers will be fabricated at a dental laboratory. At the first appointment all front teeth are prepared, impressions are taken, and the teeth are given a temporary covering. In 2 to 3 weeks the veneers are back from the laboratory, the temporaries are removed and the veneers are
permanently bonded to the teeth. Laboratory fabricated veneers are usually made using porcelain or pressed ceramic, and are very esthetically pleasing.
The advantage of veneers versus crowns is that much less of the tooth structure is removed, and the procedure is generally less uncomfortable.
E.Max, Bruxzir, and Other Metal FREE Crowns
All dental crowns fit over a structurally compromised tooth, in order to restore functionality, straighten and restore the appearance of the broken tooth. In standard practice, dental crowns were made from porcelain material which was fused to metal. Unfortunately the thin porcelain layer could break away from the metal crown, or after some time just wear away and leave the visible dark metal margin at the gum line. These crowns also have the unnatural opaque shade.
In the last few years a breakthrough was made with a more durable, long lasting and more translucent option: ALL –Porcelain Crowns. They are made from a solid piece of porcelain or zirconium, which makes the crown very durable, less bulky, allowing more of the natural tooth’s structure to be saved, hypoallergenic, and very aesthetically pleasing.
