Treating Discoloured Teeth With Composite Bonding

Composite bonding – a straightforward option to improve discoloured teeth!

What causes tooth discolouration?

There are many reasons why your teeth may become discoloured. The most common is simply as a result of staining from colour-rich foods and drinks, including tea, coffee, curries and beetroot. Typically these stains can be blasted away with a professional cleaning session using airflow polish.

Deeper discolourations can be due to tooth development issues, decay, trauma or if the nerve inside the tooth has died. Your dentist will help to uncover the cause of the discolouration with you, which will help to then provide the most suitable options to improve the tooth or teeth affected!

Will whitening my teeth be enough?

If the discolouration in your teeth is mild, a simple course of professional tooth whitening can certainly provide excellent results in a minimally-invasive way. In fact, we would generally recommend tooth whitening in the first instance, as the results alone can be enough to lift your smile. We recommend the Enlighten whitening system, which comes with a guaranteed shade improvement!

What options do I have after whitening?

Particularly if the shapes of your teeth are not symmetrical, or if there is especially deep discolouration that is not completely resolved with whitening, it is recommended to cover the face of the tooth or teeth involved with a veneer, to mask the underlying discolouration. This can be done in either composite or porcelain.


  • Minimal or no removal of tooth structure required.
  • One appointment to complete 
  • On average lasts 3-7 years, depending on home care
  • Good aesthetics
  • Easily reparable


  • Usually requires some removal of tooth structure for optimal strength.
  • At least two appointments to complete
  • Long lasting if well looked after
  • Excellent aesthetics 

Particularly for younger patients, we may advise a composite restoration at first, due to the minimally-invasive nature of the treatment. This will then still leave porcelain veneers as a future option!
