Teeth Whitening (Boutique Whitening)
Teeth whitening is a safe and effective cosmetic treatment designed to lighten the colour of your teeth and remove staining. At King Cross Dental, we use Boutique Whitening, a professional-grade system that delivers reliable, natural-looking results.
When might you consider teeth whitening?
You may benefit from teeth whitening if:
Your teeth are stained or discoloured
You want a brighter, whiter smile
You have staining from coffee, tea, red wine, or smoking
You’re preparing for a special occasion or event
You want to enhance your smile before other cosmetic treatments
What does the treatment involve?
Boutique Whitening is a custom-made, at-home whitening system:
Consultation & assessment
We check your teeth and gums to ensure whitening is suitable
Impressions & trays
Custom trays are made to fit your teeth precisely
Whitening gels provided
You’ll receive Boutique Whitening gels to use at home
At-home whitening
You wear the trays daily (daytime or overnight options available)
Treatment usually takes 1–3 weeks, depending on your desired result
Will it hurt?
Whitening is generally comfortable, but some patients may experience:
Temporary tooth sensitivity
Mild gum irritation (usually due to excess gel)
These effects are normal and usually settle shortly after treatment.
What to expect during treatment
Gradual improvement in tooth colour over 1–3 weeks
Best results achieved with consistent daily use
You may need to avoid staining foods and drinks during treatment
Aftercare & long-term care
To maintain your results:
Avoid excessive intake of staining foods and drinks
Stop or reduce smoking where possible
Maintain good oral hygiene (brushing and flossing)
Attend regular check-ups and hygiene visits
Top-up whitening may be required periodically
Lifespan & maintenance
Results can last several months to a few years, depending on lifestyle
Occasional top-up treatments help maintain brightness
Your custom trays can be reused for future whitening
Risks & limitations
While Boutique Whitening is safe and effective, it’s important to understand:
Results vary depending on the original tooth shade and type of staining
Whitening does not change the colour of fillings, crowns, or veneers
Some patients may experience temporary sensitivity
Overuse can lead to increased sensitivity or irritation
Deep or intrinsic stains may require alternative treatments
Important note
Teeth whitening is a cosmetic treatment and results are not permanent.
Good maintenance is essential to keep your smile bright.
