Questions
How can I find a dentist in Barrie, Ontario?
Visit Northern Horizon Dental Barrie at 632 Yonge Street for comprehensive dental services. Our welcoming team provides personalized care for individuals and families in a modern, comfortable setting.
How do I care for my retainer?
Clean your retainer daily with water and soft brush, avoid heat exposure, and store properly when not in use. Contact us immediately if damaged for proper replacement.
Why choose dental implants over bridges?
Implants offer permanent tooth replacement requiring strong jawbone structure, while bridges suit multiple missing teeth. Our dentists will recommend optimal solutions based on individual oral health assessments.
Why is flossing important?
Flossing removes bacteria between teeth and along gum lines that brushing misses. Daily flossing prevents cavities and gum disease by eliminating overnight plaque buildup between dental visits.
How do I know if my child needs orthodontic treatment?
Watch for crooked teeth, speech difficulties, delayed baby tooth loss after age 12, or chewing problems. Our dentists will evaluate your child's specific needs during comprehensive examinations.
Are teeth whitening results permanent?
Professional whitening lasts several months with proper care. Avoid staining foods and maintain good oral hygiene. Touch-ups may be needed periodically to maintain desired brightness levels.

So unprofessional. The assistant with red hair has a very loud dirty mouth and can be heard cussing and using inappropriate language from other rooms. The lady Anna at reception is extremely rude and does not even smile or use a friendly tone. And the lady dentist seems like she has no clue what shes doing and asks even the assistants what to do at times. The only good thing about this place is their hygienists and Dr. Sullivan, as they have always been great and friendly. Save your money and go somewhere else

Thank you so much for a great experience. As a new patient, Dr. Hanna was very thorough, patient and very kind. Was putting off dental work for some time but I'm motivated to go back.
