Process
|
|
Teeth whitening is obtained via oxidation. Free oxygen radicals remove the stains in your teeth (oxidation). This finally causes the stain to disappear from your teeth. Though the teeth whitening process can also be done at home, it is always advisable to approach your dentist for the teeth whitening. Teeth whitening supervised by dentist is always recommended as it requires full examination and necessary precaution prior to treatment.
The teeth become noticeably clean after the bleaching procedure. The whitening materials also have a positive effect on the gums asthe peroxide based agent used in the whitening materials improves the health of the gums. The tooth whitening materials were initially used in gum irritation treatment during orthodontic treatment.

| Bleaching will not change the colour of your fillings and crowns. While doing bleaching these may need replacement with lighter shade restorations. Bleaching should be avoided if there is any gum disease, decay or leaking fillings. |

After a successful root canal treatment the pulp chamber sealed, the hollowed out crown of the tooth was filled with a bleaching paste and then finally sealed with a temporary filling. The bleaching paste was replaced every week until the desired lightness was achieved. The bleaching paste and temporary filling were removed and a permanent restoration was placed. |
