Teeth Whitening

1️⃣ What is Teeth Whitening?

Teeth whitening is an aesthetic dental treatment that removes stains and discoloration from teeth.
Chemical agents or laser technology break down pigments in the enamel, resulting in a brighter and whiter smile.

2️⃣ Teeth Whitening Methods:

🔹 1. In-Office Whitening (Laser Whitening)

✅ Performed by a dentist in a clinic.
✅ Uses a strong whitening gel with 30-40% hydrogen peroxide.
✅ Activated with laser or LED light.
✅ 3-4 shades lighter in 30-60 minutes.

🔹 2. At-Home Whitening

✅ Dentist provides custom whitening trays with 10-20% carbamide peroxide gel.
✅ Worn 4-8 hours per day for 7-14 days.
✅ More gradual and controlled whitening.

🔹 3. Combined Whitening (Home + Office)

✅ One of the most effective methods.
✅ First, a laser whitening session is done at the clinic.
✅ Then, at-home whitening trays are used for maintenance.
✅ Results last 6 months to 2 years.

🔹 4. Store-Bought Whitening Products

✅ Whitening toothpaste, strips, and powders remove surface stains.
✅ However, they do not provide deep or long-term whitening like professional treatments.

3️⃣ Whitening Agents and Their Effects

💠 Hydrogen Peroxide (H2O2) – Powerful oxidation, fast whitening.
💠 Carbamide Peroxide – Slower and more controlled whitening, best for at-home use.
💠 Laser & LED Light – Activates whitening agents and speeds up the process.
