Our team of trained dentistry professionals at AC Dental of Langhorne offers a family care experience that will not only provide you and your loved ones with top-quality dental treatment, but a warm and welcoming environment. Our practice can cover all of your family’s dentistry needs, including:

Routine Cleanings

It is vitally important for people of all ages to have their teeth cleaned regularly. In the case of small children, this is even more important for developing healthy adult teeth later in life. Our dental practice offers utterly painless cleanings performed by experienced professionals to keep smiles wide and teeth shining bright.

Composite Fillings

Fillings are one of the most common methods used to restore teeth which have begun to decay. At AC Dental of Langhorne, we offer composite fillings that match the natural look and feel of your teeth which can be completed in just one appointment.

Dental Implants

Implants are an ideal way to replace missing teeth that offer beautiful results while looking, feeling, and functioning just like natural teeth. Implants can also be used to provide a method for attaching dentures that can even be snapped in or out for a secure fit and easy cleaning process. Ask one of our practice’s dental professionals how implants can improve the quality of your smile and life!


Endodontics, or root canals, are often a necessary treatment for preserving a tooth by stopping or preventing infection. Most commonly, root canals are needed to address oral injuries or excessive tooth decay. In most cases, our experienced Endodontist can treat the tooth with great success by alleviating discomfort and providing a tooth structure which can be restored with a crown.


Periodontics, or gum treatments, are vitally important for maintaining healthy teeth and avoiding bone loss. Periodontal treatment can help to restore optimal health to teeth and gums while avoiding the need for future dental surgery.


Invisalign is a popular alternative to traditional braces which is available at AC Dental of Langhorne. We can help straighten teeth with a clear, custom-fit retainer which is virtually invisible. Talk to one of our local dentistry experts to find out if you’re a candidate for this convenient and painless alternative to metal braces!
