Composite Bonding / Dental Bonding

About the Procedure

Composite bonding uses tooth-coloured resin that is applied directly to the tooth to improve its shape, size or colour. The material is layered, shaped and polished to blend with your surrounding teeth. Bonding can usually be completed in one visit.

Some minor reshaping of the natural tooth may be needed for proper adhesion and appearance.

Risks and Complications 

Composite bonding is a common and conservative cosmetic treatment, but it does have limitations and possible risks:

1. Tooth Sensitivity – some people may experience temporary sensitivity to sweet, hot or cold foods, or when biting.

2. Chipping or Wear Over Time – composite resin is softer than porcelain and may chip, crack or wear from normal chewing, biting hard foods, or grinding habits.

3. Discolouration – composite can stain over time from coffee, tea, wine, smoking, or certain foods.
Unlike natural teeth, composite cannot be whitened once stained.

4. Surface or Edge Breakdown – small cracks or roughness can develop at the edges of the bonding, which may trap plaque if not monitored.

5. Limited Longevity – bonding generally does not last as long as porcelain alternatives.
Replacement or maintenance may be required as the material ages.

Treatment Considerations

  • Bonding is shaped and polished to match your natural teeth.
  • Your dentist may use local anaesthetic if small adjustments to the tooth are required.
  • You may notice your teeth feel slightly different for the first few days.
  • Regular dental check-ups help monitor the bonding for chips, wear or staining.
  • Good brushing and flossing are important for long-term appearance and health. 

Alternative Options

Depending on your goals and tooth condition, alternatives may include:

  • No treatment
  • Teeth whitening (for colour improvement only)
  • Porcelain veneers
  • Crowns (if the tooth is more heavily damaged)

Your dentist will discuss which option best suits your situation.

Important Information
