Understanding Tooth Decay: A Preventable Epidemic

Tooth decay—clinically known as dental caries—is one of the most prevalent chronic diseases worldwide, yet it is almost entirely preventable. At our South Kensington practice, we combine advanced diagnostics with minimally invasive techniques to catch decay early and restore teeth to their natural beauty and function.

Decay begins silently. Long before you feel pain or notice a hole, acid-producing bacteria are demineralising your enamel. By the time symptoms appear, the damage may have progressed significantly. This is why regular examinations are crucial—our experienced dentists can detect early decay that is invisible to the untrained eye, often before it even requires a filling.

Modern restorative dentistry has evolved dramatically. Gone are the days of conspicuous silver amalgam fillings. Today, we use tooth-coloured composites and ceramics that are virtually indistinguishable from natural enamel. The result is a restoration that looks natural, functions beautifully, and preserves as much healthy tooth structure as possible.

What Causes Tooth Decay?

Understanding the causes of decay empowers you to prevent it. Tooth decay is essentially a bacterial infection, but several factors must align for cavities to form:

01

Bacteria (Plaque)

Your mouth hosts hundreds of bacterial species. Certain strains—particularly Streptococcus mutans—metabolise sugars and produce acid as a byproduct. This acid attacks enamel, beginning the decay process. Plaque, the sticky film that forms on teeth, provides a habitat for these bacteria.

02

Sugars and Carbohydrates

Every time you consume sugar or refined carbohydrates, you're feeding decay-causing bacteria. Frequency matters more than quantity—sipping a sugary drink throughout the day causes more damage than consuming it quickly. Each exposure triggers a 20-minute acid attack on your enamel.

03

Time

Decay doesn't happen overnight. It requires prolonged acid exposure. This is why consistent oral hygiene is so protective—regular brushing and flossing disrupt bacterial colonies before they can cause significant damage.

04

Susceptible Tooth Surfaces

Some areas are more vulnerable: the grooves (fissures) on biting surfaces, spaces between teeth, and areas around existing restorations. Weak enamel, dry mouth (xerostomia), and receding gums also increase risk.

Stages of Tooth Decay

Decay progresses through predictable stages. Understanding these helps you appreciate why early intervention is so valuable:

Stage 1: Demineralisation

White spots appear on enamel where minerals have been lost. At this stage, decay can often be reversed with fluoride treatment and improved hygiene—no drilling required.

Treatment: Preventive (Fluoride application, hygiene coaching)

Stage 2: Enamel Decay

The enamel begins to break down, forming a small cavity. Usually painless at this stage. A small filling can restore the tooth completely.

Treatment: White filling (From £195)

Stage 3: Dentin Decay

Decay reaches the softer dentin layer beneath enamel. Progression accelerates. You may experience sensitivity to sweet, hot, or cold. A larger filling or inlay is needed.

Treatment: Filling or Inlay (From £195-£795)

Stage 4: Pulp Involvement

Bacteria reach the pulp (nerve chamber), causing inflammation and pain. This is the toothache stage. Root canal treatment is typically required to save the tooth.

Treatment: Root canal + Crown (From £995)

Stage 5: Abscess

Infection spreads beyond the tooth, forming a pus-filled abscess. This can cause severe pain, swelling, fever, and in rare cases, life-threatening complications. Emergency treatment is essential.

Treatment: Emergency drainage, antibiotics, root canal or extraction

Clinical Insight: The cost difference between treating Stage 1 decay (often free with preventive care) and Stage 5 (potentially £2,000+) is dramatic. This is why we emphasise regular check-ups—catching problems early saves both teeth and money.

Treatment Options

At Cosmetic Dentistry Clinic, we tailor treatment to the extent of decay and your aesthetic preferences. Our philosophy is always minimally invasive—we preserve as much natural tooth as possible.

1. White Composite Fillings (From £195)

The modern standard for treating small to medium cavities. White fillings are made from composite resin—a blend of glass particles and acrylic that bonds directly to tooth structure.

Benefits:

  • Invisible—matched precisely to your natural tooth shade
  • Bonds to enamel, strengthening the tooth
  • Requires less drilling than amalgam (more tooth preserved)
  • Mercury-free and biocompatible
  • Completed in a single appointment

2. Porcelain Inlays and Onlays (From £795)

For larger cavities where a standard filling might compromise tooth strength, porcelain inlays offer a superior solution. These are precision-crafted in a dental laboratory and cemented into place.

Benefits:

  • Stronger and more durable than composite for large restorations
  • Porcelain mimics natural enamel's light-reflecting properties
  • Highly stain-resistant
  • Can last 15-25 years with proper care
  • Preserves more tooth than a crown

3. Dental Crowns (From £995)

When decay has destroyed significant tooth structure, a dental crown may be necessary. This custom-made cap covers the entire visible tooth, restoring strength, shape, and appearance.

Ideal for:

  • Teeth weakened by large fillings or decay
  • Following root canal treatment
  • Cracked or broken teeth
  • Severely worn teeth

4. Root Canal Treatment (From £595)

If decay reaches the pulp, root canal therapy can save the tooth. Contrary to reputation, modern root canal treatment is typically painless—comparable to having a filling.

Prevention: The Best Treatment

While we excel at treating decay, we'd rather help you avoid it entirely. Prevention is central to our philosophy:

Professional Care

  • ✓ Regular examinations (every 6-12 months)
  • Professional cleaning to remove plaque and tartar
  • ✓ Fluoride treatments for high-risk patients
  • ✓ Fissure sealants for vulnerable teeth
  • ✓ Early detection with digital X-rays

At-Home Care

  • ✓ Brush twice daily with fluoride toothpaste
  • ✓ Clean between teeth daily (floss or interdental brushes)
  • ✓ Limit sugar frequency, not just quantity
  • ✓ Wait 30 minutes after eating before brushing
  • ✓ Consider prescription-strength fluoride if high-risk

"I was terrified of the dentist after a bad experience years ago. Dr. Andreia was incredibly gentle and patient. She found decay I didn't even know I had and fixed it completely painlessly. The white fillings look completely natural—you can't tell they're there. I actually look forward to my check-ups now!"

Frequently Asked Questions

How do I know if I have tooth decay?

Early decay often has no symptoms—this is why regular check-ups are crucial. As it progresses, you may notice: sensitivity to sweet, hot, or cold; visible holes or dark spots; pain when biting; or persistent bad breath. If you experience a toothache, decay has likely reached the nerve and requires prompt attention.

Are white fillings as strong as silver (amalgam) fillings?

Modern composite materials are remarkably strong and suitable for most restorations. For very large cavities in back teeth subject to heavy chewing forces, we may recommend a porcelain inlay or onlay for superior durability. We'll discuss the best option for your specific situation.

Can I replace my old silver fillings with white ones?

Yes, amalgam replacement is one of our most popular procedures. We remove old silver fillings safely and replace them with tooth-coloured restorations. Many patients are amazed at the aesthetic improvement. Learn more about amalgam replacement →

Will treating my cavity hurt?

No. We use effective local anaesthesia to ensure complete numbness before any treatment. Most patients report feeling only pressure, not pain. For anxious patients, we offer additional comfort options. Our gentle approach has converted many dental-phobic patients into regular attendees.

How long do white fillings last?

With proper care, composite fillings typically last 7-15 years. Factors affecting longevity include filling size, location, your bite forces, and oral hygiene. Porcelain inlays and onlays can last 15-25 years or more. We'll monitor your restorations at each check-up and advise if replacement is needed.
