3 Ways To Transform Your Smile

Dental Implants

Dental implants are a popular and effective solution for missing teeth. Our implants are made of biocompatible materials that mimic the look and function of natural teeth. With proper care, dental implants can last a lifetime and give you the confidence to smile, eat, and speak with ease.

Why choose dental implants:

  • Long Lasting
  • Low Maintenance
  • Strength and Durability

Dental Veneers

Dental veneers are a cosmetic dentistry solution that will improve the appearance of your smile by masking imperfections such as cracks, chips, stains, and gaps. Mid Peninsula’s veneers are custom-made to match the shape and color of your existing teeth, giving you a natural-looking smile that you can be proud of. With proper care, dental veneers can last for many years and enhance your overall confidence and self-esteem.

Why choose dental veneers:

  • Improve appearance of stained, discolored, or misshapen teeth
  • Closing gaps and correct misalignments
  • Reshape or lengthen short and stubby teeth
  • Strengthen and protect teeth
  • Non-invasive procedure
  • Long-lasting and natural teeth

Crowns & Bridges

Crowns and bridges are dental restorations that can help repair and improve the function and appearance of your teeth. Crowns are custom-made porcelain caps that are placed over a damaged or decayed tooth to protect and restore it to its original shape and size. Dental bridges anchor to neighboring teeth and are used to replace one or more missing teeth.

Why choose crowns & bridges:

  • Natural appearance
  • Low maintenance
  • Restore function
  • Protect teeth from further damage
  • Perfect alternative to dental implants

Why Patients Love Dr. Kostagianni

"This review is for Dr. Kostagianni who helped my mother for her upper and lower dentures. My mother's dentures were loose and she could not eat properly. I called the dental office and Dr. Kostagianni helped my mother with the fitting and adjustment. She is knowledgeable and explained the treatment process thoroughly. I was very comfortable knowing that mother is in her care. I highly recommend Dr. Kostagianni if you ever need prosthodontic treatments."

Ashley N.

"Dr. Katerina Kostagianni is not only exceptionally nice but also extremely professional. She demonstrates a level of care for my teeth that surpasses even my own, meticulously focusing on every detail. Throughout the entire treatment process, particularly during the front teeth implant procedure, I happened to have my wedding. Dr. Katerina Kostagianni ensured that I looked perfect on my special day. It was a wonderful experience working with her, and the final results are truly remarkable."
