A study undertaken by British American Tobacco has shown that teeth exposed to cigarette smoke over a period of 2 weeks became very discoloured very quickly, whereas teeth exposed to e-cigarette vapour or vapour from glo, a tobacco-heated product, did not (Figure 1). After 2 weeks of almost continuous exposure, these teeth were almost indistinguishable from teeth that were not exposed to anything at all.
