Teeth exposed to cigarette smoke over a period of 2 weeks become very discolored quickly, whereas teeth exposed to e-cigarette vapour or vapour from go, a tobacco-heated product, do not.
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 discolored 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, these 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 color. 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 Vape e-cigarette and a tobacco heating product, go, were assessed for tooth discoloration and the impact on teeth compared to that of cigarette smoke.
A puffing robot was used to puff on the products to produce smoke and vapour. In each case, the smoke or vapour was collected onto a filter pad and then a solvent was used to extract the solid material from the filter pad. The impact of the extracted material (extract) on tooth discoloration was then tested using cows’ teeth.
