Houston-based dentist Dr Tasneem Mahmood has caused a social media uproar after she claimed cavities are contagious. “Thinking about the kiss I gave my husband even though he has cavities,” she writes in her now viral video on TikTok. The video was captioned, “And that’s on cavities being contagious.”Her comment was news to her followers, with many just plain horrified at the thought. The bacteria that causes cavities may be transferred during the exchange of saliva in kissing, sharing utensils and so on,” she says. This acid dissolves the calcium phosphate in our teeth and leads to decay, which can cause cavities and bad breath.
