The Ultimate Guide to Professional Teeth Whitening in London

A bright, white smile is one of the most sought-after cosmetic improvements. But with so many whitening options available, how do you know which is right for you? This comprehensive guide covers everything you need to know about professional teeth whitening in London.

Why Professional Whitening?

While over-the-counter whitening products may seem convenient, professional teeth whitening offers significant advantages:

• Stronger, more effective formulas — Professional treatments use higher concentrations of whitening agents that are only available through licensed dentists.
• Customised treatment — Your dentist can tailor the treatment to your specific needs and sensitivity levels.
• Safer application — Professional supervision ensures your gums and soft tissues are protected.
• Faster, more dramatic results — Achieve up to 8 shades whiter in a single session.
• Longer-lasting effects — Professional treatments penetrate deeper for results that last.

Types of Professional Whitening

In-Office Whitening (Zoom/Laser)

In-office whitening is the fastest way to achieve a dramatically whiter smile. At our South Kensington clinic, we use the advanced Zoom whitening system, which can whiten teeth up to 8 shades in just one hour.

The process involves:

1. Protecting your gums with a special barrier
2. Applying professional-strength whitening gel
3. Activating the gel with a special LED light
4. Repeating for 3-4 cycles of 15 minutes each

Take-Home Whitening Kits

Custom take-home kits offer professional-grade results with the convenience of whitening at home. We create custom-fitted trays that ensure even distribution of the whitening gel and protect your gums.

Treatment typically involves wearing the trays for 30-60 minutes daily for 2-3 weeks, though some patients see results within days.

Combination Treatment

For the best results, many patients opt for a combination approach: an in-office session for immediate results, followed by a take-home kit for maintenance and touch-ups.

What Causes Tooth Discolouration?

Understanding why teeth become discoloured helps you make informed decisions about treatment and maintenance:

• Food and drinks — Coffee, tea, red wine, and dark-coloured foods contain chromogens that attach to enamel.
• Tobacco use — Tar and nicotine cause stubborn brown and yellow stains.
• Age — Enamel thins over time, revealing the yellowish dentin beneath.
• Medications — Certain antibiotics, antihistamines, and blood pressure medications can cause discolouration.
• Trauma — Damage to teeth can cause them to produce more dentin, darkening the tooth.

Who Is a Good Candidate?

Most people with healthy teeth and gums are good candidates for professional whitening. However, whitening may not be suitable if you have:

• Severe tooth sensitivity
• Extensive dental restorations (crowns, veneers, or fillings on front teeth)
• Gum disease or cavities that need treatment first
• Intrinsic staining (discolouration from inside the tooth)

During your consultation, we'll assess your oral health and discuss the best options for your specific situation.

How Long Do Results Last?

Professional whitening results typically last 1-3 years, depending on your lifestyle and oral care habits. To maintain your bright smile:

• Brush twice daily with whitening toothpaste
• Limit staining foods and drinks
• Use a straw for dark beverages
• Rinse with water after consuming staining substances
• Schedule regular hygiene appointments
• Use your take-home kit for periodic touch-ups

Is Whitening Safe?

When performed by a qualified dental professional, teeth whitening is completely safe. The most common side effect is temporary tooth sensitivity, which typically resolves within a few days of completing treatment.

At our clinic, we take extra precautions to minimise sensitivity, including using desensitising agents before and after treatment.
