To work out how to remove stains from the teeth, we must first determine whether they come from the inside or the outer surface of the tooth.
Intrinsic tooth staining comes from the inside surface of the tooth called the dentine, which sits underneath the enamel. Over time, dentine can become darker/more yellow in colour. Dentine can also be stained by medications such as tetracycline.
Extrinsic tooth stains sit on the external surface of the tooth, the enamel. Generally speaking, food and drinks that are dark in colour can stain the enamel of the teeth.
Extrinsic stains on the teeth can be removed by seeing your dentist or hygienist every 6 months for a scale and clean appointment. A scale and clean involves removing plaque, calculus and stains from the teeth. After this process, if you are still unhappy with the colour of your teeth and would like them to be whiter, teeth whitening may be an option. Refer to our blog post ‘ISO-Snacking… what will stain your teeth during these times of increased snacking!’ to see which foods and drinks can be offenders when it comes to extrinsic tooth stains.
Intrinsic stains are a little more difficult to remove. They cannot be removed via mechanical cleaning; and require a chemical intervention. Teeth whitening can whiten teeth that are stained intrinsically. Teeth whitening can be performed in a couple of different ways:
