What to Expect from Professional Teeth Whitening

Every smile is unique, and so are the results. The before and after photos below show real patients from our South Kensington teeth whitening clinic. Most patients achieve dramatically whiter teeth within 2 weeks using our Boutique home whitening system.

Results vary depending on your starting shade, the type of staining, and how consistently you use the treatment. At your consultation, our dentist will assess your teeth and give you realistic expectations for what whitening can achieve for you.

What Affects Your Whitening Results?

Several factors influence how white your teeth can become

🎨

Starting Shade

Teeth that are yellow or brown typically respond better to whitening than grey-toned teeth. Our dentist will assess your natural shade and predict likely results.

Type of Staining

Surface stains from coffee, tea, wine, and smoking respond excellently. Deeper intrinsic stains (from medications or fluorosis) may need longer treatment.

⏱️

Treatment Compliance

Consistent daily use of your whitening trays produces the best results. Most patients see significant improvement in 10-14 days.

🦷

Dental Health

Healthy teeth and gums whiten more evenly. We'll check your oral health at your consultation and address any issues first.

Setting Realistic Expectations

We believe in honest, transparent advice. Here's what you should know:

  • Most patients achieve 6-8 shades improvement – but this varies based on your starting point and stain type.
  • Natural teeth only – crowns, veneers, and fillings won't change colour with whitening.
  • Results aren't permanent – expect 1-2 years before a top-up is needed (just £35 for new gel).
  • Some sensitivity is normal – usually mild and temporary. We can adjust treatment if needed.
  • Results appear gradually – you'll see changes from day 7-10, with full results at 10-14 days.

If whitening isn't suitable for you, or if we think you won't achieve the results you want, we'll tell you honestly at your consultation. We'd rather you make an informed decision than be disappointed. Have questions? View our FAQs.
