You know that ultimate confidence comes from an authentic combination of health and beauty - but did you know that confidence often starts with a smile? A smile that shines with health warms up a room, draws people in and brightens everyone's day. That is exactly the reason Dr. Richard Sigismondi offers dental care that is about so much more than comfort or technological advancements.

Every procedure we offer is performed with the optimal combination of function and aesthetics. The great architect Frank Lloyd Wright said Form follows function - that has been misunderstood. Form and function should be one, joined in a spiritual union. This is the approach we take to your dentistry: when we provide care for your smile, we are working to make it look as good as it feels and to feel as good as it looks.
Services
We want your experience with us to be unprecedented - every dental visit; every procedure. Our entire team is dedicated to your needs, making sure appointments are convenient, relaxing and absolutely comfortable. We ensure that plenty of time is spent listening to you and discussing your options. And we do everything we can to make your dentistry affordable by offering interest-free payment plans with CareCredit.
Your oral health is intrinsically tied to your physical health. Great general dental care won't just keep your smile bright and cavity-free, it will help protect your immune system, your heart and even your pregnancy! Our general dentistry takes protecting both your teeth and your overall health into perfectly balanced consideration.
When something goes wrong with your smile, you want to be sure that you are getting the healthiest, most comfortable and most attractive restoration possible. That is what you will always find at the office of Richard M. Sigismondi, DMD. We never use metal in our dental fillings - not only does metal in your mouth look unattractive and outdated, it is also unhealthy for your teeth and your body.
Is your smile everything you'd like it to be? Is it straight, white and whole, or are you dealing with the embarrassment of broken, aging or stained teeth? Cosmetic dentistry from Dr. Richard Sigismondi can help you get the smile you want and need. We can't emphasize it enough: Our dentistry combines health and aesthetics for superlative smiles.

Absolutely amazing experience with a root canal. Gentle and professional. What more could you ask for.
I waisted 43 years going to hack dentists and causing myself pain and grief. Wish I would of went straight to Dr. SIGISMONDI day one.

My wife and I are indeed fortunate to be under the oral care of Dr. Sigismondi.
He, and his staff, are professional and friendly. For each visit, I enter the office with the confidence that any issues I might have will be readily addressed.
Dr. Sigismondi is able to attend to potential problems and to provide solutions well before they appear and cause complications.His evaluations are thorough and comprehensive.

Dr Sigismondi is the man!!
I've been going to him for about 5 years and he was recommended by to me by my wife's periodontist Dr Scharf.
Dr Sigismondi is obsessively thorough and uses only the best equipment and technology available! I'd say he is a pioneer of his trade. In 2011 he put a crown on my back molar and he did it without going through the hassle of putting in a temporary crown. That's because he has the equipment to digitally scan my mouth and then have the machine make it while I watch my favorite TV show or just listen to music. When the crown was done it fit perfectly!!
