Our teeth can become discoloured or darkened over time. The main reasons for discolouration are staining agents such as coffee, tea, red wine, smoking, etc, that adhere to the surface of our teeth. Whitening or bleaching can be done to remove this surface stain, brightening or restoring our natural whiteness. The process is quite simple and involves taking molds or impressions of your teeth, from which custom bleaching trays are made. The bleaching agent is administered into the trays and the whitening trays are worn at your convenience.
