Years of coffee, tea, wine, or tobacco slowly dull your enamel and stain your teeth, and the shift is often so gradual that you don’t notice how much your smile has changed.
Many people start smiling less in photos, holding back in social situations, or feeling self-conscious in job interviews and first impressions, even when nothing else about their oral health has changed.
Our teeth whitening in Kirkland lifts years of surface staining in a single visit, so your smile looks as bright as it feels, without waiting weeks for store-bought strips to make a difference.
This treatment lifts stains directly from your enamel. Dr. Hedayati carefully applies a professional-strength whitening gel during a single in-office visit.
Our in-office teeth whitening restores what years of staining affect, including:
Once the gel has had time to work, your teeth look noticeably brighter, in a shade that matches naturally rather than looking artificial. This teeth whitening treatment fits into a single appointment, so that you can walk out with a visibly brighter smile the same day, without weeks of daily maintenance.
Dr. Oveys Hedayati, D.D.S., has practiced dentistry since 2010, and his experience is a big reason patients choose Kirkland Dental Excellence for teeth whitening. His dental education began at Tehran Azad University Dental School (IAU), followed by postgraduate training in Restorative Dentistry at UCLA School of Dentistry from 2015 to 2017. He also holds a certification in Implant Dentistry from Tehran University of Medical Sciences, and he’s licensed to practice in Washington State under an active dental license (DE60734395), with an NPI number of 1154849735.
When it comes to cosmetic care, his approach stays gentle, precise, and focused on results that hold up naturally over time. His focus areas span a full range of dental needs, including:

From the moment I walked in, the front desk staff were welcoming, helpful, and made check-in a breeze. The office itself is clean, comfortable, and has a calming atmosphere that immediately put me at ease. The hygienist and dentist had such great bedside manner—friendly, professional, and genuinely caring. They explained everything clearly and made sure I was comfortable throughout the entire visit. It’s rare to find a team that combines excellent care with such outstanding customer service.

They are very careful in the work they do—much better than other dentists I have gone to in the past. I strongly recommend them.Posted on Google Jill TeigeTrustindex verifies that the original source of the review is Google. Dr. Davis has been my dentist for years, ever since he took over the practice from Dr. Fong, and I think I've interacted with just about everyone in the office, and they are all INCREDIBLE. Seriously, these are some of the kindest, most professional, totally on the ball people you will ever have the pleasure of visiting for a dental appointment. I'm sad to be leaving the state, because it means I will no longer be able to go to Eastview Family Dental, which is a tragedy. They really are the best!Posted on Google Don WhalenTrustindex verifies that the original source of the review is Google.

We look at your current shade and talk through your goals, so we can set realistic expectations before we begin.
We make sure your teeth are clean and healthy, since surface plaque and tartar can affect how evenly the whitening gel works.
We apply a professional-strength whitening gel to lift stains from your enamel, checking your progress throughout the visit.
You leave with noticeably whiter teeth in a natural-looking shade, along with simple aftercare tips to help your results last.
Because whitening treatments are considered a cosmetic treatment, most dental insurance plans don’t cover them, even if the rest of your plan covers preventive or restorative care. Some patients ask about their plan just in case, since coverage details vary.
At Kirkland Dental Excellence, we’re upfront about the cost of teeth whitening from the start and can walk you through any available financing options. Call us at (425) 827-2003 to ask about pricing and see how we can make your whitening treatment easier to fit into your budget.
