1. Step 1: Assessing Tooth Discoloration
Before any whitening procedure, dentists first evaluate the type and severity of staining.
Common types of discoloration:
Extrinsic Stains (Surface Stains)
- Coffee, tea, red wine
- Smoking
- Long-term plaque buildup
✔ Typically appear yellow or brown
✔ Located on the outer enamel layer
👉 These stains respond very well to in-office whitening
Intrinsic Stains (Internal Discoloration)
- Tetracycline staining
- Fluorosis
- Aging-related changes
✔ Located deeper inside the tooth
✔ Often grey, dark, or uneven
👉 Require a more controlled or gentle whitening approach
💡 Important:
Not all whitening treatments are the same. Choosing the wrong method can lead to sensitivity or unsatisfactory results — this is why proper assessment is essential.
2. Step 2: Choosing the Right Whitening Method
Based on your condition, dentists typically recommend one of the following:
Option 1: Strong In-Office Whitening (Pola Office / Laser Whitening)
- High-concentration whitening gel
- Activated using LED light or laser
- Designed for fast and visible results
✔ Best for:
- Yellow stains from food and drinks
- Smoking-related discoloration
- Patients wanting immediate whitening
⏱ Treatment time: 60–90 minutes
📈 Results: noticeable immediately after 1 session
⚠️ Possible effects:
- Mild sensitivity for 1–3 days
Option 2: Low-Sensitivity Whitening (White Excent)
- Gentle whitening formula with lower peroxide levels
- Designed to protect enamel and reduce sensitivity
- Gradual whitening approach
✔ Best for:
- Sensitive teeth
- Mild to moderate intrinsic stains (including some tetracycline cases)
- Patients concerned about discomfort
✔ Advantages:
- Minimal to no sensitivity
- More controlled, natural-looking results
⏱ May require: multiple sessions for optimal results
💡 Clinical Insight:
Strong whitening systems deliver faster results, while gentler systems like White Excent focus on comfort and long-term safety.
3. Step 3: Teeth Whitening Procedure (At the Clinic)
The whitening procedure is straightforward and typically completed in one visit.
Step-by-step:
- Teeth Cleaning
- Remove plaque and surface stains
- Ensures even whitening results
- Shade Assessment
- Record your starting tooth color
- Gum Protection
- Protective barrier applied to gums
- Whitening Gel Application
- Gel applied evenly to teeth
- Activation Phase
- LED light or laser used (depending on system)
- Multiple cycles (15–20 minutes each)
- Final Rinse & Result Check
- Gel removed
- Immediate results evaluated
⏱ Total treatment time: 60–90 minutes
4. Step 4: Results After Whitening
- Teeth appear visibly whiter immediately after treatment
- Final shade stabilizes within a few days
Expected outcomes:
- Extrinsic stains → strong, fast improvement
- Intrinsic stains → gradual improvement over time
💡 For gentler systems like White Excent:
→ Results may improve progressively over multiple sessions
5. Step 5: Sensitivity & Aftercare
Common after-effects:
- Mild sensitivity to hot/cold (1–3 days)
- More common with strong whitening systems
Aftercare recommendations:
- Avoid coffee, tea, red wine for 48–72 hours
- Avoid smoking
- Maintain good oral hygiene
- Use desensitizing toothpaste if needed
6. Limitations of Teeth Whitening
Teeth whitening is effective for many patients, but results depend on the underlying cause.
⚠️ Important considerations:
- Severe tetracycline staining may not fully respond
- Some cases may require multiple sessions
- Alternative treatments (e.g. veneers) may be recommended
