Why do I have to tell my medical history to my dentist?

It is important to let your dentist know your medical history. It is also important that you update it regularly, so your dentist knows your current information. 

This includes information on 

• all current and previous medications (including inhaled, injected, lozenge and cream medications)
• any vitamins, minerals, supplements, or medications bought without a doctor’s prescription 
• allergies and intolerances
• medical conditions
• recent hospitalizations
• surgeries within the last 2 years
• recent testing of your conditions, for example: if you have high blood pressure or diabetes, when they were last checked and what the readings were
• if you are pregnant or breastfeeding
• if you smoke, vape, take illicit drugs, or drink alcohol
• if you have a family history of cancer
• if you have any dental anxiety
• details of your emergency contact and doctors currently caring for you

Fill it out when you arrive

When you arrive at your appointment, you will be asked to fill out a medical history form. Your dentist will read and talk with you about your answers. If your medical history is complicated, it may be helpful for you to bring a copy of your medical history or medications from your doctor. 

Your dentist may also ask about:

• habits such as smoking, vaping, illicit drug use and drinking alcohol
• your family's dental history
• your past dental treatments
• how you care for your teeth at home
• the foods and drinks you have most often.

There are many reasons why it is important for your dentist to know your medical history. Reasons can include:

• medications can have side effects in your mouth
• medical conditions can cause changes in your mouth
• the health of your mouth can affect some medical conditions
• some medications may cause a dry mouth and increase your risk of developing tooth decay or infection
• some medications and supplements can increase bleeding or increase the risk of problems in your mouth after certain dental treatments
• smoking, drugs and alcohol can affect how well your mouth heals after dental procedures and increase your risk of oral cancer
• it helps your dentist and other medical professionals care for you if you have an unexpected medical emergency. 

Update it when you return

Each time you return to your dentist for an appointment, they may ask if your medical history has changed. This lets them stay up to date to care for you safely.
