The method of teeth whitening and home teeth whitening was first presented around 1989, giving the medical and consumer health awareness communities enough time to judge its effectiveness and safety. Generally, the teeth whitening process has been given a good report in regards to both safety and effectiveness.

What should you consider when you are looking at the safety of teeth whitening? Here are a few tips to take into consideration:

Both medical and consumer communities have raised some concerns about the risks involved with bleaching. Some bleaching agents may pose cancer-causing risks.

Studies have shown, however, that the concentration of carbamide peroxide in teeth whitening products will not cause any cancer in mouth tissues or gums. An agent naturally present in saliva seems to offset the amount of peroxide that's emitted by teeth whitening agents.

Much consideration and attention has also been given to the fear of damage or erosion of tooth enamel caused by bleaching agents. After careful study, medical experts now say that more damage is done to a tooth's enamel by soft drinks or fruit juices than by tooth whitening bleaches.

The issue of nerve endings being affected by teeth whitening is still in its early stages since this can be studied only in longer intervals such as five to eight years after the teeth whitening procedure. Despite this concern there is still little damage being shown to teeth that have undergone whitening and been in for a five to eight year checkup after the process.

If you have existing caps or crowns, you are not able to undergo teeth whitening processes. You may have the procedure done if you have had a root canal and if you have simple fillings. Dental histories have not indicated any problems from this procedure but, again, these studies are still in their infancy.

While the above mentioned studies are valid and accurate it is still best to consult with your dental health professional to decide your best course of action.

Every patient has a unique dental history, so what works for some people may not be the best choice for you. Even the most perfect smile isn't worth posing risks to your health.
