Tooth Bleaching

Over the past few years, the topic of tooth bleaching has become very common.  There are several different types of tooth bleaching to choose from.  They vary in everything from cost to effectiveness.

As the name implies, tooth whiteners or bleachers lighten the color of the tooth surface because they contain peroxides, or bleach components as the active ingredient.  A very common side effect of tooth whitening is sensitivity in the teeth.  Teeth contain microscopic dentinal tubules that run from the nerve of the tooth to the surface of the tooth.  A tooth will become sensitive when the fluid in these tubes moves around.  Normally, minerals in saliva plug the ends of the tubes that are at the tooth surface.  The introduction of bleaching gels can dissolve these plugs, leading to the fluid in the tubes moving around, causing tooth sensitivity.  In addition, some individuals are genetically more susceptible to tooth sensitivity.  Sensitivity due to tooth bleaching is temporary, and will normally go away when the bleaching is discontinued.

Tooth bleaching is available in many different over the counter dental care products.  From toothpastes to mouthwashes to tooth whitening strips, there are quite a few products to choose from that are advertised as having teeth bleaching abilities.  These types of tooth whiteners are usually the most inexpensive.  The effectiveness of these products will vary depending on such factors as how often and continuously they are utilized.

A visit to your dentist will introduce two more choices in teeth whitening products.  Your dentist can make a custom mold of your teeth and provide you with tooth whitening gel to use with this tray for in-home bleaching.  Because it is specifically molded to your teeth, this method is usually a bit more effective than those that you can purchase in a store.

The last tooth whitening method is in-office tooth bleaching.  This is typically the most effective method of tooth whitening.  The effectiveness of the peroxide is enhanced through several factors.  The teeth will be kept dry during the process through the use of gauze as well as a device called a retractor, which will pull the lips away from the teeth while the peroxide is applied.  The gel can be left on for 30 to 60 minutes.  Also, sometimes the teeth will be exposed to a curing light or laser to further activate the peroxide.

No matter which method of tooth bleaching appeals to you, talk to your dentist to find out more about which products and methods they recommend.  No matter what your budget might be, there is a product out there for you!

Teeth Whitening Options For Children and Adolescents

By Vishant Nath DMD

Most adults are quite aware of the opportunities for teeth whitening. From toothpastes to whitening strips to whitening treatments at the dental office, there are plenty of ways to make the smile brighter. Due to an interest in teeth whitening for younger patients, the American Academy of Pediatric Dentistry has issued new guidelines. This article will provide information based on these guidelines.

There are numerous instances where primary (baby) teeth or permanent teeth could become discolored. Dental trauma can cause tooth discoloration. There can be irregularities in the enamel color of an infected tooth. There can also occur intrinsic discoloration and staining of teeth. A discolored tooth can lead to negative self-image, especially in the adolescent years.

Many pediatric dentists will offer in-office bleaching. In-office bleaching has many advantages. It will begin with an initial professional examination to diagnose the causes of the discoloration and address any concerns such as side effects. The dentist will also identify existing tooth restorations that are faulty or could be effected by the bleaching process.

Also with in-office bleaching there is the opportunity to use advanced technologies such as lights and lasers to enhance the treatment. Photographs and shade guides can aid in documenting the effectiveness of the treatment. The dentist can also provide physical barriers to prevent or minimize the exposure of the whitening agent to the soft tissues in the mouth. This can help to decrease the effect of irritation in these soft tissues.

Additionally, in-office bleaching provides for more rapid and stable results than can be guaranteed with at-home bleaching.

If at-home bleaching is preferred, your dentist can assist by fabricating a custom-bleaching tray. The customized tray can help to ensure optimum fit and greater efficiency of bleaching agents.

All of these methods of teeth bleaching have been deemed safe for children. The most common side effects are tooth sensitivity and gum irritation. Both are usually temporary and disappear at the end of the bleaching treatment. It’s also important to note that tooth whitening is often not a permanent fix. Depending on what caused the discoloration originally, it can return over time.

Teeth whitening offers another way to improve the look of your child’s smile. It may not be for everyone, but it’s an important tool to keep in mind. Talk with your dentist to find out more about teeth whitening!
