Cosmetic Dentistry

For many people an attractive smile is an important asset, this is especially true for people who have careers in the public eye. Cosmetic dentistry focuses on improving the aesthetics of a person's teeth and smile. One of the most popular forms of cosmetic dentistry is teeth whitening; a procedure which helps lightens teeth by removing stains and discoloration. The primary causes of discoloration are coffee, tea, tobacco, age and genetics.

Although anyone with permanent teeth may qualify for teeth whitening, the procedure is most successful on people who have healthy teeth and gums. In particular, cavities need to be treated before undergoing any whitening process. This is because the whitening solution can penetrate into the decay, causing further sensitivity. In addition, teeth that are yellowish in shade respond best to the whitening solution, brownish teeth less well, and grey colored teeth many not respond to whitening. It should also be noted that only natural enamel respond to teeth whitening; fillings, crowns and tooth colored resin will not respond to the whitening. For those who do qualify, teeth whitening and bleaching have been proven be both safe and effective. Furthermore, even a change of just two or three shades can make a noticeable difference.

There are several options when it comes to teeth whitening: whitening toothpastes, over the counter whitening strips and gels, tray based whitening systems and in office bleaching. Whitening toothpastes are only able to remove surface stains and typically lighten your teeth's color by one shade. Whitening strips and gels both contain peroxide and results are usually seen in a few days, typically the results are sustained for four months. Tray based whitening systems can be purchased either over the counter or from your dentist. As the name suggest, tray based whitening, involves wearing a mouth guard like "tray" for a couple of hours every night for up to four weeks. Both over the counter and dentist provided tray whitening systems contain peroxide; however, only a dentist will be able to provide you with a tray that is customized to fit your teeth exactly. Over the counter trays are one-size-fits-all; if the tray is an ill fit, the whitening gel may seep onto the gums, causing irritation. In office bleaching provides the most efficient and effective method for whitening teeth, although it does cost more than tray based at home bleaching. The whitening products are used in conjecture with heat, laser or a special light to accelerate the process. Results can be achieved in one hour, in particular, laser based bleaching can provide dramatic results in one hour. Other forms of in office bleaching may need several appointments to achieve very dramatic results. In office bleaching lightens teeth color approximately three to seven shades lighter.

As always, it is important to consult with your dentist to ask what form of whitening works best for you.
