Dental Design

We know you have choices. We strive to be your first.

At Dental Design, we don’t believe that the perfect smile should be reserved only for the wealthy and elite. Every patient deserves to have the brightest and whitest smile possible. We also believe that achieving that smile shouldn’t be a financial imposition. Dental Design was made for you.

Established in Freshwater in 1993, Dental Design was and still is committed to offering the best personal dental care and service to every single one of our patients. Dr Harminder Sian understands that each individuals’ dental needs are the utmost priority.

Our practice was built on the foundation that “we understand that everyone has individual needs and desires. Our ultimate goal is to give everyone a great healthy smile that they can be proud of and most importantly maintain throughout their life.”

We have a state-of-the-art facility, professional staff who are dedicated to your comfort and care, and the ability to work within almost any budget.

Min - Principal Dentist


Dr Harminder Sian, or Min as he prefers to be called, was born in sunny Leeds, Yorkshire, during the Swinging Sixties. The youngest of eight children, Min was never short of hand-me-downs! Of Indian parentage with a strong Kenyan influence, he has been blessed with a blend of the different cultures that have helped shaped his life.

He graduated from Manchester University in 1988 and worked in London for a couple of years before coming to his senses and migrating to Australia in 1991. His first position was as an associate dentist in the Blue Mountains, a beautiful introduction to life and work in his new homeland.

Min bought this practice, then located on the corner of Lawrence and Oliver Streets in Harbord, in 1993. The practice relocated to Carlton Street in 2000 before finding its current home in Dee Why at the start of 2014.

He married Narinder in 1995. They welcomed a daughter, Arina, in 1997 and a son, Rajan, in 1999. However, the golden child is their Poodle/Chihuahua cross, Rey! Min can often be seen at Bunnings on weekends with Rey taking a ride in the trolley!

Min has always taken a keen interest in sports, playing a lot of football (the proper type!), hockey, cricket, and rugby union over the years. However, the advancing years mean the bones creak and the muscles ache a lot more nowadays! A lifelong fan of Leeds United, Min’s mood can often be determined as to how well they went at the weekend!!

With a passion for his work and a love for the latest technologies, Min has always sought to improve the practice. Attending many courses and investing in high-tech equipment has resulted in a modern, smooth-running practice that showcases the advancements dentistry has made over the past couple of decades. His particular interests are in Invisalign, being a registered provider since 2006, and implants, placing his first implant in 1999. Aesthetic dentistry, which allows him to improve the looks and confidence of his patients, is another aspect he loves.

Blending professionalism with a warm, welcoming approach has always been his style, and his goal is always to make his patients feel like they are Number One! He looks forward to looking after the health of your mouth and therefore impacting in a positive way on your general well-being.
