I have been a patient of Dr Hansen’s for almost thirty years. I grew up in New England, with unfluoridated, low-mineral-content water. And I have a sweet tooth… So I have twenty-eight fillings. Thanks to Dr Hansen’s careful replacement of old, large amalgams, I still have 31 of my 32 teeth(I broke a wisdom tooth ten years ago) and only one root canal. Every one of his restorations has lasted without problems, for decades. My only dental pain was from the broken wisdom tooth. His hygienists are thorough, careful, and skilled. They typically work in the office for several years. They make a point of giving feedback and training on my hygiene, and giving detailed explanations of specific areas that need attention. My appointments have always started on time. I’ve recommended Dr Hansen to three friends, all of whom have been pleased and impressed.
