Professional Teeth Whitening

Want a brighter, more radiant smile? Professional teeth whitening is a safe and effective way to achieve a smile that dazzles. At Dr. Samuel Cho, Family Dentistry in Maple Valley, we offer professional teeth whitening treatments that can be done at home with a take-home kit, or in our office in a single visit if you prefer.

For a brighter, more vibrant smile you’ll love to share, call our team at 425-432-2299 to schedule a professional whitening treatment.


  • Fast Results: Professional-strength whitening works faster than over-the-counter kits that can take weeks or even months to show results. Whether you whiten at home or in our office, you will see a noticeable difference sooner.
  • Safe and Effective: Our professional-grade whitening agents are safe for your teeth and gums, and we take precautions to protect your oral health throughout the whitening process.

Professional teeth whitening uses a special whitening gel, also known as a bleaching agent, that is carefully formulated to break down stains and discoloration and is much stronger than over-the-counter products. Most of our patients whiten at home with a take-home kit, wearing the gel as Dr. Cho directs. If you would like faster results, in-office whitening is available: we apply the gel in our office and use a special light to speed up the process.


After your teeth whitening treatment, you can maintain your brighter smile by practicing good oral hygiene, avoiding foods and drinks that can stain your teeth, and scheduling regular dental cleanings. We also offer take-home whitening kits for touch-ups, allowing you to maintain your dazzling smile from the comfort of your own home without disrupting your lifestyle.


The cost depends on which option you choose. Most of our patients whiten at home with a take-home kit, and in-office whitening is available if you’d like a brighter smile in a single visit. Dr. Cho explains the cost of each option at your consultation, and our team is happy to check what your dental plan covers.

Some people notice tooth sensitivity during whitening, and in most cases it’s temporary. If your teeth already tend to be sensitive, tell Dr. Cho before you start so he can recommend the right approach. Take-home whitening lets you go at your own pace and pause for a day or two if your teeth need a break.

Most of our patients whiten at home, and it’s what Dr. Cho normally does. A take-home kit lets you brighten your smile on your own schedule and touch up later as needed. In-office whitening brightens your smile in one visit, so it can suit you if you have an event coming up. Dr. Cho will help you choose based on your timeline and your teeth.

No. Whitening only lightens natural teeth, so crowns, veneers and bonding keep their original shade. If you have restorations on teeth that show when you smile, talk with Dr. Cho before you whiten. Whitening first, then matching any new or replacement restoration to your brighter shade, usually gives the most even result.
