How Does Teeth Whitening Work?
A bright, white smile is often seen as a sign of health, youth, and confidence. That’s why teeth whitening is one of the most popular cosmetic dental procedures available today. Whether your teeth have become stained from years of coffee drinking or you simply want to enhance your natural smile, professional teeth whitening can help you achieve the results you’re looking for.
At Beckstead Dental Group, the cosmetic dentist Palo Alto loves for safe and effective teeth whitening solutions, we offer both in-office and take-home options. But how exactly does this treatment work, and why does it make such a big difference? Let’s break it down.
Why Teeth Become Discolored
Before exploring how teeth whitening works, it helps to understand why teeth get discolored in the first place. There are two main types of discoloration:
1. Extrinsic Stains
These stains occur on the outer layer of the tooth (the enamel) and are typically caused by:
- Coffee, tea, and red wine
- Tobacco use
- Dark-colored sodas or berries
- Poor oral hygiene
2. Intrinsic Stains
These stains form within the inner layer of the tooth (the dentin) and can result from:
- Aging
- Trauma or injury
- Certain medications (like tetracycline)
- Excessive fluoride exposure during tooth development
While brushing and regular cleanings can remove some surface stains, intrinsic discoloration and deeper stains require professional whitening treatments to see noticeable improvement.
How Professional Teeth Whitening Works
Professional teeth whitening uses high-concentration whitening agents that break down stains on and within the teeth. The most commonly used agents are hydrogen peroxide or carbamide peroxide. Here’s what typically happens during a professional whitening treatment at our office:
- Evaluation: Your dentist will first examine your teeth and gums to ensure you’re a good candidate for whitening. This is especially important if you have restorations like crowns or fillings, which won’t respond to whitening agents.
- Preparation: We begin by cleaning your teeth to remove plaque and debris. Your gums and soft tissues are then protected with a barrier to avoid irritation from the whitening gel.
- Application: The whitening gel is applied to the surfaces of your teeth and activated with a special light (in some cases). The peroxide in the gel breaks down into oxygen molecules, which penetrate the enamel and dentin, dissolving stains and brightening your teeth.
- Rinse and Reveal: After about 15–30 minutes (depending on the system used), the gel is removed, and the results are evaluated. In some cases, multiple sessions may be recommended for optimal brightness.
Take-Home Whitening Trays
In addition to in-office treatments, Beckstead Dental Group also offers custom take-home teeth whitening trays. These trays are made to fit your teeth perfectly and are used with a professional-strength whitening gel.
You simply wear the trays as directed by your dentist — usually for 30 to 60 minutes a day over one to two weeks. Take-home trays are a convenient option if you want to whiten your smile gradually or maintain the results of your in-office treatment.
Benefits of Professional Teeth Whitening
Professional whitening treatments offer several advantages over over-the-counter products:
- Faster results: In-office whitening can make your smile several shades whiter in a single visit.
- Customized care: Treatments are tailored to your specific needs and sensitivity level.
- Even whitening: Custom trays and professional application ensure uniform results.
- Reduced sensitivity risk: Our team takes precautions to protect your gums and reduce discomfort.
If you’ve tried drugstore whitening kits without success, professional whitening from a cosmetic dentist in Palo Alto could be the solution you’ve been looking for.
How Long Do Teeth Whitening Results Last?
Whitening is not permanent, but with good oral hygiene and occasional touch-ups, your results can last from several months to a few years. Avoiding staining foods and drinks and not smoking will help maintain your new, bright smile.
Are There Any Side Effects?
The most common side effect is temporary tooth sensitivity, which typically goes away within a few days after treatment. Our team can provide guidance on managing sensitivity and recommend desensitizing toothpaste if needed.
Should Everyone Whiten Their Teeth?
While many people are great candidates, whitening isn’t recommended for:
- Children under 16
- Pregnant or nursing individuals
- Patients with gum disease or untreated dental issues
- People with many crowns or fillings in visible areas
A consultation is the best way to find out if teeth whitening is right for you.
