It is easy to get an estimate of a laser teeth whitening cost online or from your dentist, but its true cost may be considerably higher. These hidden factors can greatly increase your overall costs.
Your final cost may well consist of the combination of not so obvious factors involved in this teeth whitening process.
One treatment may not be enough
Although it is expected that you should get your desired white teeth after just one treatment, it has been noted in the medical literature that on average it takes three treatments to make patients happy. Sometimes people need from two to six whitening treatments to achieve their desired effect.
One of the reasons for this may be in the fact that during the laser teeth whitening your teeth are exposed for a prolonged time to a strong heat. This exposure dehydrates teeth. As teeth dehydrate, they get whiter. Thus, your whitening effect is greatest immediately after the laser whitening treatment. As teeth re-hydrate with time, and it can take up to seven days, they tend to revert to their normal darker color.
The dentists know this and therefore recommend further treatments to achieve maximum whiteness.
Add at-home whitening kit
After you have had your laser teeth whitening you will most likely be recommended to follow it with an at-home whitening procedures.
This at-home treatment will be able to compensate for the loss of white color due to teeth re-hydration. Hydrogen peroxide based at-home whitening kits provide further whitening effect.
The other reason for using at-home whitening kits after the laser teeth whitening lies in the fact that during the whitening procedure the dentist needs to isolate your teeth from soft tissues to prevent their damage and discoloration.
Such isolation is more difficult to achieve on the back teeth. That is why laser teeth whitening quite often performed just on the front teeth.
Once the whitening has been completed, your back teeth, especially upper molars, may be prominent when you smile and affect your overall look. To compensate for this, you will need to use an at-home bleaching kit.
You will need to enquire with your dentist if the cost of the kit is included in your laser teeth whitening cost.
Fix your old restorations
The third and not that obvious laser teeth whitening cost is associated with any previous tooth restorations that you may have had.
You have to remember that only natural tooth enamel will whiten and all your previous restorations such as veneers, crowns, bridges etc. will not. So, after you have had a laser teeth whitening procedure they will be considerably darker than your shiny white teeth.
Additional procedures and costs may be required to rectify this problem
These are the three most important factors that you have to keep in mind when calculating your true laser teeth whitening cost.
