Dental Education & Prevention is at the Heart of Our Dental Office

Sure, we are here to help replace a missing tooth, enhance your smile or get you out of pain – fast. However, this is not our primary goal. In fact, our philosophy is just the opposite. Our top priority is to be your advocate. We want to help you learn how to properly care for your teeth and gums, so dental problems are prevented. Whether you have major dental issues or a perfect smile, you can count on our dentist and team to answer all your questions and to build a healthy dose of education into every visit.

Family Friendly Dentistry Makes it Possible for Everyone to Smile

For nearly 50 years, the dentists and team at Costello Dental Excellence have been proud to serve the Arlington Heights community. We are honored to be seeing the third generation of families first treated by Dr. John when he opened his dental office in the Randhurst Mall. From coaching Little League to visiting schools with free, educational programs, we go above and beyond to help our friends and neighbors smile. Our patients routinely comment that they have never been treated better – anywhere – and Dr. Ernie looks forward to carrying-on the family tradition of exceptional dental care for the next 50 years in Arlington Heights.

Regardless of your situation, our team – led by Liz– takes the time to help you understand all aspects of your care and ensure financial concerns do not stand between you and the smile of your dreams.
