One Provider, Always
At Skyhills Dental, you’ll always see Dr. Catherine Zacal. This means true continuity of care from preventive visits to restorative dentistry, crown and bridge work, implant restoration, and emergency care.

​

Every treatment recommendation—including Xrays—is made only after a complete clinical exam and full health history review. This personalized approach ensures the lowest radiation exposure possible, following the ALARA (As Low As Reasonably Achievable) principle.

​

Dental Sleep Medicine
Skyhills Dental is built on an overall health model—because your teeth don’t exist in isolation. Dental Sleep Medicine plays a major role in helping us protect your smile for the long term.

 

Dr. Catherine Zacal has written a dental journal article for the Ontario Dentist (September 2026 issue) and continues to publish on this topic. Her work is especially helpful for anyone dealing with broken teeth, severe wear or grinding, TMJ concerns, or acid erosion.

 

To make this information accessible to patients, she also shares educational videos on her YouTube channel @DrCatherineZacalDDS.

 

Self Referral for Snoring, Sleep Apnea & TMJ Care

You don’t need a referral—and you don’t need to travel far—to receive care for snoring, sleep apnea, or TMJ dysfunction.

 

As a Diplomate of the American Board of Dental Sleep Medicine (ABDSM), Dr. Zacal collaborates closely with local physicians and sleep specialists at the Hospital Alliance Group. Her training allows her to assess how Sleep Related Breathing Disorders—mouth breathing, snoring, UARS, and sleep apnea—affect your teeth, jaw joints, and overall oral health.

 

Flexible Cleaning Options
We believe your hygiene visits should fit your life.

You can enjoy cleanings at our office using Guided Biofilm Therapy, or you can alternate visits between Skyhills Dental and your favorite independent hygienist. Depending on your needs, we may recommend a 6, 9, or 12 month schedule.

Cybersecurity & Communication You Can Trust

With the rapid growth of AI, cybersecurity matters more than ever. We partner with a dedicated third party cybersecurity company to keep your information safe.
And because speaking to a real person matters, we prioritize answering your calls personally during office hours. After hours, you can still enjoy peace of mind booking through our online scheduling system. All questionnaires and forms are available on our website—either to print or complete securely online.

Environmental Responsibility
Sustainability has been part of our philosophy since moving from Mississauga to Muskoka in 2008. We carefully consider environmental impact when choosing dental materials, office products, and even how we structure appointment times to help reduce unnecessary travel. Our goal is always to make a positive contribution to our community and surroundings.
