We all like to make candy and sugar the culprit for unhealthy teeth, but the reality is cavities are caused by bacteria – like Streptococcus mutans and Streptococcus sobrinus – that cling to the teeth. This bacteria creates an acid by-product that ultimately destroys your tooth enamel.
The gross thing about it all is just like a cold or the flu can be shared from one person to the next, so can this cavity-creating bacteria. Sharing food, drinking off of someone and kissing are the most common ways to swap this bacteria.
