Implant + Perio Clinic

Teeth whitening remains one of the most popular cosmetic dental treatments, but not all whitening systems are the same. At the Implant and Perio Clinic in Marylebone, London, we mainly offer two professional whitening options: Enlighten Evolution home whitening and Philips Zoom in-office whitening.

Both systems can produce beautiful results when used correctly, but they work differently and suit different patients depending on lifestyle, sensitivity, and expectations.

Why Do Teeth Become Darker?

Teeth naturally darken over time due to:

  • Coffee, tea, red wine, and smoking
  • Natural ageing
  • Certain medications
  • Trauma to teeth
  • Genetics and enamel thickness

Professional whitening works by using peroxide-based gels that safely penetrate the enamel and break down stain molecules inside the tooth.

What Is Enlighten Whitening?

Enlighten is a premium dentist-prescribed home whitening system designed to gradually whiten teeth over approximately three weeks. The treatment usually follows a staged protocol:

  • Week 1: conditioning phase
  • Week 2: whitening phase
  • Week 3: intensive finishing phase

Patients wear custom-made trays, mainly overnight, using carefully controlled whitening gels. One of the major advantages of Enlighten is that it focuses heavily on reducing sensitivity while still achieving very bright, natural-looking results.

Pros of Enlighten

  • Excellent long-term whitening results
  • Gradual and controlled whitening
  • Lower risk of severe sensitivity
  • Custom-made trays for comfort and precision
  • Good for patients with sensitive teeth
  • Allows better colour stability over time

Cons of Enlighten

  • Requires commitment and compliance
  • Takes around 3 weeks
  • Overnight tray wear may not suit everyone
  • More expensive than over-the-counter systems

What Is Philips Zoom In-Office Whitening?

Philips Zoom is an in-clinic whitening treatment carried out by a dentist. A high-strength whitening gel is activated during a single appointment, often producing noticeably whiter teeth immediately.

This is ideal for patients wanting faster results for weddings, holidays, events, or simply those who prefer treatment carried out professionally in one visit.

Pros of Philips Zoom

  • Immediate visible whitening
  • Treatment completed in one appointment
  • Ideal for busy patients
  • Professionally monitored throughout
  • Excellent for stain removal and brightness boost

Cons of Philips Zoom

  • Higher likelihood of temporary sensitivity
  • Results may appear slightly less gradual or natural initially
  • Some patients still benefit from home top-ups afterwards

Why Does Sensitivity Occur During Whitening?

Sensitivity is one of the most common questions patients ask about whitening. Whitening gels temporarily open microscopic channels within the enamel so oxygen molecules can break down stains. During this process, the nerve inside the tooth can become temporarily irritated. Sensitivity is usually:

  • Temporary
  • Mild to moderate
  • More common in naturally sensitive teeth
  • Often triggered by dehydration or overuse of whitening gels

At our clinic, we carefully assess every patient before whitening to minimise risks.

Who Is a Good Candidate for Whitening?

Professional whitening works best for:

  • Healthy natural teeth
  • Yellow-toned staining
  • Patients with good oral hygiene
  • Patients without active decay or gum disease

Whitening may be less effective for:

  • Crowns, veneers, fillings, or composite bonding
  • Grey discolouration
  • Internal staining from trauma or medication

This is why a proper dental examination before whitening is extremely important.

What Whitening Cannot Do

A common misconception is that whitening changes the colour of existing dental work. Whitening does NOT whiten:

  • Crowns
  • Veneers
  • Composite bonding
  • Fillings
  • Implants

Sometimes whitening is carried out first so that existing restorations can later be matched to the brighter shade.

Is Professional Whitening Safe?

When supervised properly by a dentist, professional whitening is considered safe and minimally invasive. Problems usually arise when:

  • Cheap online products are used
  • Trays do not fit properly
  • Gels are overused
  • Whitening is carried out without checking dental health first

At the Implant and Perio Clinic, whitening is always tailored individually and carried out under professional supervision.

Which Whitening System Is Better?

There is no single “best” whitening system — only the right system for the right patient. Patients who prefer gradual whitening, lower sensitivity, and long-term maintenance often prefer Enlighten.

Patients wanting rapid whitening, immediate results, and a one-visit treatment often choose Philips Zoom. In some cases, combining both approaches provides the best outcome.

Professional Teeth Whitening in Marylebone & Harley Street

At the Implant and Perio Clinic, we offer doctor-led whitening consultations to assess:

  • tooth shade
  • sensitivity risk
  • gum health
  • existing restorations
  • and suitability for whitening

Every smile is different, and whitening should never be a one-size-fits-all treatment. If you are considering professional teeth whitening in London, we would be happy to guide you through the safest and most suitable option for your smile.
