2. Cavities caused by kissing
This is purely a bizarre incident as one would not think that kissing can cause cavities but this is the truth. A woman in her 40s suddenly developed gum disease and cavities. She had never had these problems earlier. Investigations revealed that the problems had occurred only after she had seeing a man. It was surprising to know that the man did not follow good oral hygiene and had not consulted a dentist in the past 18 years. So each time he kissed the woman, he passed on some of his bacteria to her.
