Dr Mariana Denes
Aesthetic Smile Design & Restorative Dentistry
Warm, thorough and patient-focused, Dr Mariana Denes is known for her gentle approach, attention to detail, and passion for natural-looking smile aesthetics. After relocating from Brazil to Perth in 2013, she has worked in cosmetic-focused clinics, gaining extensive experience in aesthetic treatments, bite rehabilitation and minimally invasive dentistry.
She completed her Bachelor of Dental Surgery at the Pontifical Catholic University of Rio Grande do Sul (2012) and is a registered member of the Australian Dental Association. Mariana takes a comprehensive approach to dentistry—combining digital treatment planning, functional bite analysis and refined aesthetic techniques to create long-lasting, harmonious results. She believes cosmetic dentistry should enhance a patient’s natural features, not overpower them.
With a strong interest in functional and aesthetic dentistry, Mariana enjoys helping patients improve their oral health while also elevating confidence through tailored smile design. She prioritises patient education, ensuring every individual understands their options and feels comfortable throughout their treatment journey.
Her calm and reassuring manner helps even anxious patients feel at ease, and she is especially skilled at guiding patients who may be undergoing cosmetic dentistry for the first time or who have had negative dental experiences in the past.
