Cosmetic Dentistry

In the past decade there has been a dramatic interest in cosmetic dentistry. We all realize that having a healthy, bright, beautiful smile enhances our appearance and allows us to smile with confidence. Thanks to the advances in modern cosmetic dentistry, we are able to improve our teeth and smiles with quick, painless and surprisingly affordable treatments.

Some of our Cosmetic Dentistry services include:

  • Ceramic Veneers

  • Tooth Whitening

  • Full Ceramic Crown & Bridge

  • Tooth Colored Composite or Ceramic Fillings

Cosmetic dental treatments can:

  • Change the size, shape, and alignment of the teeth

  • Fill in unattractive spaces between teeth

  • Improve or correct bites

  • Lighten or brighten the color of teeth

  • Repair decayed, broken, cracked, or chipped teeth

  • Replace missing teeth

  • Replace old, unattractive dental treatments

Full Mouth Reconstruction

Using the latest technologies and current techniques, our doctors have changed the smiles (and lives) of many patients.


Our team combines science, technology and art to make every patient feel their best.


We pride ourselves in the ability to provide full mouth reconstruction. Dr. Sotodeh and Dr. Knothe have spent countless continuing education hours with leading authorities in cosmetic and reconstructive dentistry.


Although every patient is unique and each case approach can be different most full mouth reconstructions involve following steps:


  • Comprehensive exam and treatment plan

  • Treating acute dental health issues including pain, infection, broken teeth, etc.

  • Producing a diagnostic 3D, physical model of your new smile.

  • Present case to you.

  • Preparing teeth as planned and fabricating Provisionals based on the 3D model.

  • Delivering the definitive restorations and your new smile.


Discuss your options with our team and let us help you to a beautiful new smile!

Our Dentists


Dr. Hagen Knothe
Dr. Hagen Knothe

Dr. Knothe has completed his dental degree from the University of Muenster, faculty of dentistry in Germany-one of Europe's most modern and advanced dental training facilities in 1993. His past appointments include assistant professor and clinical instructor at the University of Muenster and clinical instructor at George Brown College in Toronto.


He has committed himself to providing his patients with the best care possible, through participation in countless hours of high quality continuing training programs. While enjoying all facets of dentistry, his main focus lies on implant and cosmetic- restorative care as well as endodontic procedures. In his past time Dr. Knothe enjoys quality time shared with his lovely wife Dr. Sotodeh and a variety of sports like Tennis, Running, Swimming, Windsurfing, Badminton and Skiing, none of which he has mastered yet but nevertheless keeps on trying.

Dr. Nooshin Sotodeh
Dr. Nooshin Sotodeh

She graduated in 1993 from the Westfaelische Wilhelms University in Muenster / Germany. Dr. Sotodeh is known for her warm and outgoing personality. Her passion in dentistry is creating beautiful smiles through cosmetic dental procedures. She also takes great pleasure in helping children to develop the right attitude towards maintaining their healthy smiles throughout a lifetime.

Dr. Sotodeh considers continuous training of her skills and professional development an integral and very satisfying part of her career, and this continues to benefit our patients. In her leisure time she enjoys traveling with her husband (who happens to be Dr. Knothe) and spending time with her five brothers and one sister. And if none of her friends and family is available, she enjoys digital photography, watches movies, reads poems or plays mind games like Sudoku.
