Whitening or bleaching your teeth is not only safe, but very effective, but there are some precautionary measures that you should take before having it done to prevent any type of mishap.
Bleaching or whitening your teeth is not for everyone. One reason is that some people may be allergic to the peroxide solutions that are used in the procedure. You also need to be over the age of sixteen because before that time the nerves that are inside your teeth are very sensitive and tender. It can be harmful for those younger than sixteen years of age in regard to their dental health. It can cause a lot of damage to the nerves from irritation from the solution used.
You also need to make sure that the mouth trays fit in your mouth correctly. Home whitening kits only have one size mouthpiece tray while a dentist will make an impression of your teeth to make sure that the tray fits. If the tray does not fit correctly the peroxide solution could leak into your mouth and cause irritation to the soft tissues. The solution in the tray should be just enough to cover individually each tooth. Make sure that you rinse your mouth after each treatment.
You also want to make sure that you know what the correct concentration of peroxide should be because it is over the right percentage you may increase the risk of your teeth being sensitive and have enamel erosion. If you are using carbamide it should never be more than twenty-two percent and if it hydrogen peroxide it should not be more that six point six percent.
Having your teeth bleached or whitened is not a procedure that you should do on a routine basis. It should only be done once a year and no more. You should make sure that if you have any cavities that need to be filled, or if you are going to have any fillings or crowns that you do this at least two weeks before you are to get the bleaching or whitening procedure done. In addition, having a whitening treatment will not make any difference to teeth that are artificial or to fillings that are white. If you are going to have any bridges or dentures, you need to wait until after the treatment so they can match them to what your real teeth look like after the procedure. You also need to make sure that before you have the treatment that all the tarter is removed from your teeth.
