Opalescence Teeth Whitening — Brighter Smile, Professional Care
Teeth whitening is one of the fastest and most effective ways to enhance your smile and boost your confidence.
At We Smile Dental Haus, we use Opalescence, a world-renowned teeth whitening brand from the USA — trusted by dentists worldwide for its safety, proven results, and dentist-approved quality in aesthetic dentistry.
Why Teeth Whitening?
Our teeth can naturally discolor over time due to various factors such as drinking coffee, tea, or wine, smoking, or simply aging.
Teeth whitening works by using Carbamide Peroxide or Hydrogen Peroxide at clinically safe concentrations. These active ingredients penetrate deep into the enamel to break down internal stains (not just surface discoloration), revealing a naturally white and long-lasting smile.

Types of Teeth Whitening Treatments
1. In-Office Whitening
Performed under professional supervision, this method uses a high-concentration whitening gel.
The treatment takes about 45–60 minutes, and you’ll see noticeable results immediately after the session — ideal for those looking for instant whitening results.
2. Take-Home Whitening Kit
Your dentist will create a custom-made tray tailored to fit your teeth perfectly and provide you with Opalescence gel for home use.
You can choose the concentration and wear duration based on your dentist’s instructions.
This method typically takes 2–4 weeks for optimal results and provides a longer-lasting whiteness. It is also more affordable than in-office whitening and can be repeated as needed.




3. Combined Whitening (In-Office + Take-Home)
This combination offers the best of both worlds — immediate whitening results from the in-office session and extended brightness over time through at-home treatment.

Before Whitening: Preparation Tips
Get a dental cleaning and check-up before whitening.
Treat any cavities or gum inflammation beforehand.
Inform your dentist if you have sensitive teeth or any allergies to dental materials.
Aftercare Tips
- Avoid colored foods and drinks (coffee, tea, red wine) for at least 48 hours after whitening.
If needed, use a straw to minimize contact with teeth. - Avoid smoking for at least one week.
- Brush and floss regularly — using toothpaste with potassium nitrate can help reduce sensitivity.
- Mild tooth sensitivity is normal; over-the-counter pain relief may be used if needed.
- Avoid acidic foods and beverages (e.g., citrus fruits, soda) and foods that are extremely hot or cold.
- You can repeat whitening every 6–12 months to maintain your bright smile, as the whitening effect is not permanent and may fade naturally over time.
💬 Frequently Asked Questions (FAQ)
What is teeth whitening and what types are available?
Teeth whitening uses hydrogen peroxide or carbamide peroxide to remove stains within the enamel. There are two main methods: 1) In-office whitening using light or laser activation, and 2) At-home whitening using custom trays with lower-concentration gel.
Does teeth whitening damage the teeth?
When done by a dentist using approved materials, whitening does not damage tooth structure or thin the enamel. Some may experience temporary tooth sensitivity during or after the procedure.
Will I experience sensitivity after whitening?
Some people may experience mild temporary sensitivity that typically disappears within 1–2 days. Whitening every other day or using desensitizing toothpaste can help reduce symptoms. If discomfort persists, consult your dentist.
Is teeth whitening permanent?
Whitening results are not permanent. The brightness may fade after 6 months to 2 years, depending on diet and habits such as consuming tea, coffee, or red wine. Good oral hygiene helps prolong results.
Who should not undergo teeth whitening?
Teeth whitening is not recommended for pregnant or breastfeeding women, children under 16, those with untreated decay or gum disease, or those with fillings or crowns on front teeth, as artificial materials will not change color.
How can I maintain white teeth after whitening?
Avoid dark-colored food and drinks for at least 24–48 hours after whitening (“White Diet”). Maintain good oral hygiene and consider touch-up whitening at home as recommended by your dentist.
Can I whiten my teeth if I drink coffee or smoke?
Yes, but it’s best to avoid these habits during the whitening process for optimal results.
If you do drink coffee, choose iced coffee with milk, use a straw, and rinse your mouth or brush afterward to prevent staining.
