Dr Roslyn Yat

As the principal dentist of Advanced Dental Spa Ballajura, my focus is to ensure you leave the clinic gratified and confident with your new smile. A healthy mouth requires an ongoing commitment from both patient and practitioner. Patient care is essential in cultivating trust and respect, so expect to receive the best quality of service.


I cover a broad range of dental services with a particular interest in cosmetic dentistry, crowns & veneers and restoring worn down dentition. I am also certified in implant dentistry, sedation dentistry, Invisalign, wrinkle relaxers, fillers and teeth whitening.


On a more personal note, having a balanced healthy lifestyle is critical role for my work as a dentist. I enjoy keeping fit, exploring new eateries and traveling when I am not immersed in dentistry. Social responsibility and ethics play a big part in my life so I do take an active role in church ministry, community volunteering and medical missions.
