Internal Tooth Whitening
What Is Internal Tooth Whitening?
Internal Tooth Whitening or Internal bleaching is a whitening procedure commonly performed on dark teeth that have lost their vitality through Endodontic treatment ( root canal treatment).
One very dark tooth can also be a sign of extensive decay and damage to the inner structures of the tooth such as infected or dead tooth pulp. This can make a tooth appear much darker than the surrounding, healthy teeth.
If you are experiencing a severely damaged tooth that is detracting the quality of your smile, Root canal treatment can be carried out to save your tooth and Internal bleaching may be needed in the future to restore its natural white appearance.
How Is Internal Bleaching Better Than Other Teeth Whitening Treatments For My Root Canal Treated Tooth?
Teeth that appear darker (due to damage or infection or after having a Root Canal Treatment) are not likely to respond to whitening treatments that only affect the surfaces of teeth. Whitening treatments that act on the outer layer of the enamel, such as professional whitening gels, only treat the surface of the teeth whereas Internal tooth Bleaching will focus in the inner structure of the tooth.
How Is Internal Bleaching Done?
On your first appointment the dentist will take a few photographs and an x-ray of the tooth in question. Then the content of the pulp chamber will be carefully removed – this is usually a filling that was placed after completing the Root Canal Treatment. A special whitening agent (usually 100% Carbamide Peroxide) is then placed in the pulp chamber and the cavity is sealed with a temporary filling. After 4-5 days your dentist will re-examine the tooth and if both the patient and the dentist are happy, then a new permanent white filling will be placed in the pulp chamber. If the shade is still not matching the other teeth then we repeat the procedure.
What Should I Do Following Internal Bleaching Treatment?
While an internal bleaching treatment can leave an affected tooth several shades whiter, its results are not permanent. By avoiding food and lifestyle choices that contribute to staining as much as possible, you can help prolong the results of treatment and continue enjoying your white smile. You can prevent instances of decay and damage in healthy teeth by practicing good oral health, such as regular brushing and flossing.
