What Is In-Office Teeth Whitening?
In-office teeth whitening is a cosmetic dental treatment performed by licensed professionals. It involves applying a high-concentration whitening gel to your teeth, usually enhanced with a special light or laser. Unlike over-the-counter strips or whitening pens, this method is done under strict supervision, ensuring excellent results in just one session.
Why Choose In-Office Whitening Over DIY Kits?
Sure, whitening kits are available at any drugstore. But are they really the best option?
- Speed: In-office whitening can lighten teeth up to 8 shades in about an hour. DIY kits take weeks—if they work at all.
- Safety: Dentists use FDA-approved materials and monitor your gums and enamel health throughout the process.
- Consistency: No patchy results or uneven tones. Just smooth, radiant, pearly whites.
How In-Office Teeth Whitening Works
Let’s walk through the process of what to expect when you book a whitening session at Diamond Dental Care in Diamond Bar.
Preparation and Oral Exam
Before any whitening gel is applied, your dentist performs a full oral exam. This ensures your teeth and gums are healthy and that whitening is safe for you. Any signs of decay or gum disease need to be addressed first.
Application of Whitening Gel
A powerful whitening agent, usually hydrogen peroxide or carbamide peroxide, is applied directly to your teeth. A protective barrier keeps your gums safe from irritation.
Use of Light or Laser
The whitening gel is then activated using a special light or laser, enhancing its ability to break down stains and discoloration. This part takes about 15–20 minutes and may be repeated for optimal results.
Benefits of In-Office Teeth Whitening
So, why should you go for professional treatment?
- Instant results: One visit, one hour, and a visibly brighter smile.
- Customized care: Your dentist adjusts the treatment based on your tooth color and sensitivity.
- Long-lasting effect: With proper care, results can last for months.
Is In-Office Whitening Safe?
Yes, it’s incredibly safe—especially when done by professionals like those at Diamond Dental Care. They follow strict guidelines and protocols to ensure no damage is done to your enamel or gums. However, it’s not recommended for children or pregnant women.

How Long Do Results Last?
Typically, results last between 6 to 12 months, depending on your diet and oral hygiene. Avoiding stain-causing foods and drinks can extend your results. Diamond Dental Care also offers periodic touch-up sessions to keep your smile looking sharp.
Common Myths About Teeth Whitening
Let’s bust a few:
- “Whitening weakens teeth” – False. Professional treatments are safe for your enamel.
- “All teeth whiten the same” – Not true. Genetics, age, and lifestyle all affect your results.
What to Expect After Your Appointment
You might experience some sensitivity, especially to hot or cold foods. That’s normal and usually fades in 24–48 hours. Your dentist may recommend a special toothpaste to help ease discomfort.
Cost of In-Office Whitening in Diamond Bar
While pricing can vary, in-office teeth whitening typically costs between $300–$600. At Diamond Dental Care, you get high-quality treatment and expert care—worth every penny for the confidence a white smile brings.
