Talk with your dentist or hygienist about any special conditions in your mouth and any ways in which your medical conditions affect your teeth or oral health. For example, cancer treatments, pregnancy, heart diseases, diabetes, dental appliances (dentures, braces) can all impact your oral health and may necessitate a change in the care of your mouth. Be sure to tell your dentist if you have experienced a change in your general health or in any medications you are taking since your last dental visit.
