Ask About Invisalign Braces

Invisalign® takes a modern approach to straightening teeth, using a custom-made series of aligners created for you and only you. These aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear over your teeth. There are no metal brackets to attach and no wires to tighten and most people won’t even know you’re straightening your teeth.

What makes our practice eco-friendly:

  • Wind Powered Electricity

    All of the electricity used to power our office and building is powered by 100% wind energy.

  • Amalgam Separator

    Though not yet required by Pennsylvania law, we have installed a device which removes mercury from our waste water and prevents contaminants from reaching our sewer system and local waterways.

  • Digital X-rays

    We utilize digital x-rays in our office, which not only offer improved imaging and diagnostics over traditional x-rays, but allow for a significantly reduced amount of radiation exposure needed to capture an x-ray image. In addition to this benefit, caustic chemicals are not needed to develop digital x-rays and no hazardlous waste bi-products are associated with them.

  • Digital Charts

    All of records are stored digitally which eliminates paper waste.

  • Waterless Vacuum

    Our dental vacuum or suction systen is waterless, which saves about 360 gallons of water per day compared to a traditional dental vacuum system.

  • Steam Sterilization

    Our instruments are sterilized using the chemical free method of steam sterilization. This system is not only safer for the environment but also offers superior sterilization compared to traditional methods of sterilization.

  • E-Claims

    All of our insurance claims are sent electronically to insurance carriers to avoid the unnecessary waste of paper.E-Claims

  • BPA Free Composites

    We offer composite (tooth colored) fillings which do not contain the chemical bisphenol A.
