Why Is the Dentist Asking About That?
Understand why health questions appear on a dental form and how to ask about privacy without leaving important information out.

Ask what the question is for
A medical-history form can feel unexpectedly personal. If a question seems unrelated to your teeth, ask the dental team why it matters. The ODA explains that health information helps the dentist plan care and understand factors that may affect treatment.[1]
If you cannot remember an answer, write that you are unsure and ask how to check. Guessing a medication name or a previous reaction is less useful than bringing the correct information later. Tell the office if you would prefer to discuss a sensitive answer privately.
Know where the information goes
Ontario dental offices have obligations under the Personal Health Information Protection Act. You can ask who is responsible for privacy at the practice and how to request access to your record or raise a concern.[1]
Before sending records or photographs electronically, ask which method the office wants you to use. Keep appointment requests brief when a public form is involved; the team can direct you to an appropriate way to provide detailed health information. Keep your own copy of any important update so you can explain it consistently at the next visit.
