- Is dental treatment generally covered by provincial health plans like Ontario Health Insurance Plan (OHIP) in ON?

Most dental care costs are paid out-of-pocket by patients or through private dental insurance plans (often through employers) or government assistance programs for eligible groups (e.g., children from low-income families, seniors on specific benefits). Always verify your coverage and check your private dental insurance details before treatment.

- Your first visit with Dr. Dolatshahi will typically involve a comprehensive dental examination. This includes a review of your medical and dental history, a thorough check of your teeth, gums, jaw, and soft tissues (including an oral cancer screening), and any necessary X-rays. Dr. Dolatshahi will discuss their findings, address your concerns, and work with you to create a personalized treatment plan if any care is needed. Often, a professional cleaning will also be performed or scheduled during this visit or a subsequent one.
- What services does a General Dentist (Dentist) like Dr. Dolatshahi typically provide?
- A General Dentist like Dr. Dolatshahi is the primary dental care provider for patients of all ages, offering a wide range of services including: preventative care (check-ups, cleanings, X-rays, fluoride, sealants), restorative treatments (fillings, crowns, bridges), basic endodontics (root canals on less complex teeth), simple extractions, initial management of gum disease, and cosmetic procedures (like whitening or bonding if offered). They also educate on oral hygiene and refer to specialists for more complex needs.
- Are dental X-rays safe, and how often are they needed?
- Dental X-rays are very safe, especially modern digital X-rays which use minimal radiation. Protective lead aprons are used. X-rays are taken only when diagnostically necessary.

- How often should I (or my child) visit Dr. Dolatshahi for a check-up and cleaning?
