About Us
We are a specialist dental practice dedicated to providing the highest standard of endodontic care (commonly known as ‘root canal treatment’) to patients, typically referred by their general dentist.
At Apex we understand that the thought of root canal therapy can be intimidating. Whether patients come to us in pain or with previous negative dental experiences, patient comfort is always our highest priority. From consultation to follow-up, we ensure every stage of your treatment is expertly managed with care, compassion, and efficiency.
Endodontists are highly qualified dental specialists, having completed an additional three years of postgraduate training in root canal treatment. Using their extensive experience, advanced techniques, and state-of-the-art equipment, we are committed to delivering the best possible outcome for your dental health.
Wanting to move away from the Adelaide CBD, our principle endodontist, Dr Jonathan Christo, acquired a site in Adelaide’s leafy inner East in 2024, which he knew would be a convenient and accessible location to construct a custom built facility to match the high standard of care he strives to deliver.
