You’re late for work, skip breakfast and during the commute, pick up a doughnut and cup of coffee and you’re on your way. This common quick-fix breakfast scenario can lengthen your time spent in the dental chair, reports the Academy of General Dentistry (AGD). The sugars in doughnuts have been identified as a risk factor for gum inflammation and cavities. The amount of sugar and cream in your coffee also can have a direct effect on the amount of cavity-causing bacteria. If this is your breakfast of choice, ask your dentist to learn what you can do to fight back against this combination of tooth terror.
