Welcome to Valley Implants and Periodontics!

Dear Patients and Prospective Patients,


Under the advice and guidance of the American Dental Association and Washington State Department of Health, we have made the decision to close our office for the next eight weeks (3/19/20-5/17/20).  We are operating with minimum staff to decrease exposure.

We will have administrative staff monitoring calls for any emergency situations.  Emergency Care will be classified as treatment for patients in pain, infection present.  Patients who have received recent treatment requiring the evaluation of sutures and or unusual healing would also be considered appropriate for treatment.  All other treatment can be delayed until the COVID-19 crisis has eased.

Any patients referred to our office can leave a message on our office voicemail and our administrative staff will contact you as soon as possible to schedule when we have reopened.

As always, thank you all for your support and trust.

Specializing in  Placing Dental Implants

Dental implants are designed to provide a foundation for replacement teeth that look, feel, and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything and can smile with confidence, knowing that teeth appear natural and that facial contours will be preserved.

Dental implants are changing the way people live. With them, people are rediscovering the comfort and confidence to eat, speak, laugh and enjoy life. For more information about dental implants or to schedule a consultation appointment, call our office in Renton & Covington, WA at (425) 271-5812.

Cosmetic Periodontal Surgery

These procedures are a predictable way to cover unsightly, sensitive, or exposed root surfaces and to prevent future gum recession. If you are unhappy with the appearance of short unsightly teeth this can be greatly improved by a combination of periodontal procedures by Dr. AllenChen  and cosmetic dentistry by your dentist.For more information about cosmetic periodontal surgery or to schedule a consultation appointment, please call our office in WAor Covington, WA at (425) 271-5812.
