Vaping does not stain teeth
New Delhi, Mar 26 (ANI): Vaping does not stain teeth, a new research has suggested. According to a study conducted by British American Tobacco, teeth exposed to cigarette smoke over a period of 2 weeks become very discoloured quickly, whereas teeth exposed to e-cigarette vapour or vapour from glo, a tobacco-heated product, do not. Moreover, after 2 weeks of almost continuous exposure, teeth were almost indistinguishable from teeth that were not exposed to anything at all. Smokers get 'stains', turning teeth from a healthy-looking white to an unhealthy-looking yellow/brown colour. Although this staining is commonly referred to as nicotine staining, it is not caused by nicotine, but by tar in smoke. As part of a wider study on oral health, scientists at British American Tobacco studied discoloration in teeth. A prototype Vype e-cigarette and a tobacco heating product, glo, were assessed for tooth discoloration and the impact on teeth compared to that of cigarette smoke. After the first day, the teeth exposed to the smoke extract started to change colour and over the course of 14 days, teeth got darker and darker in colour. Even with the naked eye, the colour changes with the cigarette extract could be easily seen after 1 day. The exact colour change was also measured in the laboratory using a special camera that can detect tiny changes in hue. In contrast to teeth exposed to smoke those exposed to an e-cigarette or THP vapour exhibited a minimal change in colour, similar to untreated teeth. These results were presented at the annual conference of the American Association for Dental Research in Florida, US.
