      I have struggled with failing teeth almost my whole life and finally had to make a decision. From one dentist to another and they all had different ideas. Was recommended to Dr. Kostas by a periodontist. Dr. Kostas said it would be best to keep my teeth…

      Dr. Kostas and his staff are very friendly and welcoming. I was nervous getting 2 fillings without an injection but Dr. Kostas reassured me that everything was going to be alright. I would recommend this dentist office to everyone…


      Dr Kostas and his dental assistant Gina are one of the best teams that I’ve had the privilege and pleasure of being their patient. They are warm hearted and fun on top of being the best in their field…

      A dental implant is a device that replaces a tooth root. It is placed in the jawbone and is not visible inside the mouth. Its purpose is to support a prosthetic tooth, bridge or fixed appliance, and to prevent bone and soft tissue loss.

      A crown covers an entire tooth structure. Its purpose is to provide support to a tooth that has been compromised by endodontic treatment (root canal), very large fillings, or teeth that have been broken. Crowns are also used to attach a bridge or to cover an implant.

      No. Studies have shown that removable dentures without implants provide only 25% of the function of natural teeth. A fixed prosthesis retained with implants can provide 110% or more of the function of natural teeth.

      A veneer is a thin piece of porcelain that is bonded to the front surface of a tooth. Veneers can be used to change the shape or color of teeth, to give the appearance of straight teeth in a patient who has crooked teeth, or to close gaps between teeth.

      Absolutely not! With advances in implant dentistry we have many options for non-removable tooth replacement.

      Yes. It is possible to have an implant retained prosthesis that does not cover the roof of your mouth.
