Since oral health is linked to general health, your visit will likely start with a health history. Tell your dentist if you have health conditions or allergies. Also tell them if you've had surgeries. Tell them about any medicines you take, including prescriptions, over-the-counter medicines, and supplements. Also tell them about any illegal drugs you use. You may be asked about your daily tooth and gum care. Tell your dentist if you grind your teeth or often breathe through your mouth. You should also bring up any oral health issues that concern you.
