How Long Does Composite Bonding Last?

Composite bonding has gained popularity in the last few years as a cosmetic dental treatment to enhance the appearance of teeth. This process involves applying composite resin material matching your tooth colour to improve the size, shape, colour and overall look of your teeth. The impacts of this treatment are immediate and satisfying however, it is natural to wonder how long this look will last. 

What is Composite Bonding? 

This dental procedure is minimally invasive and involves applying composite resin to the surface of your tooth or teeth. The resin is carefully manipulated and shaped by the dentist to achieve the desired shape and size. This treatment can correct small imperfections, close gaps or fix chipped teeth. The resin composite is hardened using a special light cure (the blue light you may be familiar with), this results in a strong bond between the material and tooth structure. 

What Factors Affect the Lifespan of Composite Bonding? 

  • Quality of the Material: Composite resin quality can significantly impact the longevity of your restoration. High-quality resin composite, combined with efficient application offers better durability and resistance to damage or staining. 
  • Oral Hygiene: Good maintenance of your oral hygiene, such as regular brushing, flossing and check-ups is important to improve the lifespan of composite bonding. Poor oral hygiene causes plaque accumulation which can compromise the integrity of the composite bonding over time. 
  • Habits and Lifestyle: Particular habits and factors can impact how durable the composite bonding is. Biting on hard objects (pens/nails/ice) and grinding can put huge amounts of stress on the resin material which can lead to premature damage or wear. 
  • Diet: Some food and drinks can impact the colour stability of the composite bonding. Drinking lots of coffee, tea, red wine and other substances can gradually discolour the composite. Tobacco products can also stain the composite bonding, any staining can be fixed but will require touch-ups or maintenance. 

How long does Composite Bonding last? 

Composite bonding can last anywhere from 5 to 10 years. The actual lifespan is dependent on the person and the factors mentioned above. With good care and maintenance, it is possible for composite bonding to last over 10 years. 

How do I extend the Lifespan of my Composite Bonding? 

  • Maintain good oral hygiene: Brush twice daily, floss regularly and go to routine dental and hygiene appointments. 
  • Avoid excessive force: Stop habits such as nail biting, chewing on ice or using your teeth as tools (e.g. to open packets). 
  • Use Mouthguards: Custom-fitted mouthguards are advised to wear during some sports to prevent dental trauma and nightguards are recommended to reduce the impact of grinding. 
  • Minimise the consumption of substances that stain: If you do consume them, rinse your mouth with water afterwards.
  • Regular dental check-ups: These allow the dentist to monitor your composite bonding and address any problems early. 

What can Composite Bonding be used for? 

  • Chipped or broken teeth
  • Gaps between teeth
  • Discoloured or white marked teeth
  • Gum recession
  • Misshapen teeth


Composite bonding offers a versatile and aesthetically pleasing solution for enhancing the appearance of teeth. While its longevity is impacted by numerous factors, including material quality, oral hygiene, habits, and dietary choices, with proper care and maintenance, composite bonding can last around 10 years or even longer. By following good oral hygiene practices, being mindful of damaging habits, and visiting your dentist for regular check-ups, you can increase the lifespan of your composite bonding and enjoy a beautiful smile for many years. Remember to consult with your dentist for specific advice and recommendations tailored to your dental needs.
