It is important to talk to your dentist and keep them informed. Make sure to mention any sores, swelling or pain you might be experiencing in your mouth. Let your dentist know if you smoke, have any allergies or have any existing medical conditions. Also, tell your dentist about all the medications you take, both prescription and over-the-counter. Some can cause problems such as dry mouth; others may interact with medications your dentist may prescribe. An informed dentist is able to best treat you and maintain your good dental health.
