Our success however is straight up down to you our amazing patients that have recognised that as a whole we are truly present, always listening and ever evolving to continue to smash that goal right out of the park!



With over 20 years experience spent on Auckland’s North Shore in long standing clinics you can rest assured you will be dealing with real people that are not only very upfront and honest but value integrity like those of the generation before them. 


Dentists are like hairdressers. Once you’ve found a goodie you don’t want them to up and disappear.  You can rest assured both Dr Houlahan and Dr hauptfleisch aren’t going anywhere.  FLOSS’s founders have two young boys in local schools and two dental clinics on Auckland’s North Shore, so FLOSS is here to stay… phew!


We consistently aim to provide the highest quality work.  Our investment into the latest technologies and continual education ensure your visit will run as simply and smoothly as possible.  We care enough for our patients to make sure that “new and novel” is equal or better than “tried and true”.  Only local dental labs are used for your custom dental work.  You won’t believe how far dentistry has come and everyone here at FLOSS can’t wait to show you.

Compassion & Understanding

All meaningful relationships are a result of genuine understanding. We’re here to listen to you, help educate you and guide you through your dental journey. We aim to exceed your expectations and fulfil all of your dental needs so you can smile with confidence!

Convenience & Comfort

Our clinic could be confused with a modern hotel reception area or a spa… OH wait we have a spa room for all your decadent indulgence.  Why not reward yourself for coming in and getting on top of your oral health, dental and appearance needs.

We offer extended hours, a convenient location, free parking, roof mounted TV's with Netflix, anti-ageing treatments and sedation options just to name a few. 

No surprises

Those feet of yours won’t step foot outside of the premises without knowing and more importantly understanding what your treatment options are, their costs and the risks. Our joint collaboration will form the basis of your personalised treatment plan.  If you have a few options you will be able to take away your printed plan with pricing!!! to then mull over at home ( possibly with the other boss ).

We’re here to offer you a revolutionary new kind of dental practice. At FLOSS dental boutique, not only do we deliver exceptional general dentistry services six days a week but we also have an onsite spa to deliver top of the line anti-ageing treatments and treatments to enhance facial aesthetics as we understand that it often takes a multidisciplinary approach to achieving that perfect smile or eye teasing facial symmetry.
