A study done by the Boston University School of Dental Medicine has shown that there may be a protective effect of coffee drinking on your gums. The study was retrospective, looking at male veterans over a 30 year period of time. According to Dr. Nathan Ng they looked at coffee drinking, smoking, alcohol use, BMI, and dental habits. (Yes, we do need to look at women, too). There had been some studies in the past that indicated coffee might harm gums. This study instead showed a positive effect.
Great news for those of us that love our coffee! Just leave out all the sugar, people! Every time we sip on a sugared drink, the cavity causing bacteria have a good 15 minutes to work at decalcifying our teeth. If you’re like me, that cup of coffee lasts a while- I don’t chug it all at once.
