Teeth whitening using tray-based teeth bleaching systems. |
|
When won't the tray teeth bleaching systems work?The tray-based at-home teeth whitening (teeth bleaching) process is not always predictable. Most definitely some tooth discolorations will be more resistant to bleaching than others. Your dentist, as part of their initial examination, will need to ascertain the most likely cause of your tooth staining. Having done so they will then be able to convey to you what type of whitening results might be expected. (Sometimes dentists utilize computer imaging systems to illustrate for you what degree of teeth whitening they think will be possible.) |
Unnatural tooth shades.Your dentist will not be able to unconditionally guarantee that you will be pleased with the outcome of your at-home teeth whitening efforts. This is because many people have a very unrealistic idea of what constitutes a natural shade for teeth.Some people compare their teeth to the teeth of those persons they see featured in films, TV, and magazine advertisements. You should be aware of the fact that the shades of many models' and actors' teeth fall into the realm of "unnatural". Often these extreme shades of white have been achieved by means other than by bleaching (such as by placement of crowns, also known as "caps"), or else this extreme whiteness never existed at all but instead was created by touching up a picture. Persons trying to achieve extreme shades of white by bleaching can be guilty of whitener abuse, thus placing themselves in a realm where the safety of the product they are using has not been evaluated. |

At-home tray-based teeth whitening will not lighten existing dental work. |
The at home teeth bleaching processes will not make a color change in the dental work you have already had placed. This includes restorations such as: white fillings, bonding, crowns, and bridges (porcelain veneers may be affected). In most cases, a person's teeth should be whitened first and then afterwards their dental work replaced so to match the new shade of their teeth.
|
| Before the bleaching process is begun a person should have discussed with their dentist how much post-bleaching dental work will be needed. The time and cost associated with replacing dental work can be significant. |
| The fact that tray teeth whitening process will not lighten existing dental work can be advantageous in some cases. There can be instances where a person's teeth have darkened during the years after a single tooth has been crowned ("capped") and now this one lone tooth, in comparison to its neighbors, appears to be too white.
The at home teeth whitening process can be used to lighten the crowned tooth's neighboring natural teeth back to a shade which more closely matches the crowned tooth's porcelain. The color match obtained by the bleaching process is not always exact, but it can be a significant improvement. (For an example of how this technique might be accomplished in real life visit our Cosmetic Dentistry section.) |
At-home tray-based teeth whitening can possibly lighten teeth that have porcelain veneers.There is an exception to the rule that existing dental work will not lighten and this exception involves teeth with porcelain veneers. Veneers are translucent shells of porcelain that have been bonded onto the front side of a person's teeth.While the tooth bleaching agent will not change the color of the veneer itself it will be able to permeate the tooth from the backside, thus lightening the tooth structure which lies under the veneer. Because veneers are translucent, the net effect can be that the tooth, from the front side, appears whiter. |
Teeth with gum recession.Some persons have gum recession on one or more teeth. Usually the root surface that becomes visible as gums recede has an appearance that is somewhat darker than the rest of the tooth. This is because root surfaces are not covered by enamel but are instead composed of another naturally darker material called dentin.Tray teeth whitening systems won't effectively lighten dentin. This means that the color of the root portion of the tooth (which shows where the gum recession has occurred) will not change noticeably as a result of your bleaching efforts. |
