Discoloured Teeth & Fillings


The most common causes of discoloured teeth include the consumption of tea, coffee, red wine or tobacco. Unsatisfactory oral hygiene may also cause teeth to discolor over time (usually of a yellow nature), whilst several congenital medical conditions have been known to affect the aesthetics of both baby and adult teeth.


Old, stained, unsatisfactory fillings can be replaced with more aesthetic tooth-coloured fillings if desired. Silver-coloured fillings (called amalgam) contain silver, tin, copper, zinc and mercury, and have been around for a very long time, however due to its unappealing colour and mercury content, many people elect to replace them with more aesthetically pleasing materials such as composite resin.

There are several ways to improve the discolouration of teeth & fillings:


  • Regular cleans from your dentist every 6 months to prevent buildup of plaque and tartar, as well as to remove any superficial stains present.


  • In-chair or take-home whitening can improve the shade of your teeth if they have discoloured over time. Stains can be difficult to remove from whitening alone (a professional clean may be needed).



  • Tooth-coloured filling material that usually lasts between 7-12 years. When whitening does not achieve the desired result or shade, composite veneers can be done to mask the underlying discolourations. The shape of the teeth can also be improved using composite veneers, especially if they are crowded, worn or gappy. This type of filling is completed in a single appointment and can be used to mask discoloured teeth or replace discoloured teeth.


  • Porcelain veneers are thin pieces of porcelain bonded over teeth in order to change the colour of a tooth or change its shape. Porcelain veneers are highly aesthetic, although in order to allow room for a porcelain veneer, the dentist has to remove a very small amount of tooth structure from the tooth. A technician then creates the porcelain layer which is bonded onto the tooth. Porcelain veneers can be completed over 2 appointments, and last approximately 10 years or more before they may need to be re-polished or replaced.



  • Crowns are restorations that may cover some or all surfaces of a damaged or unaesthetic tooth, and usually last between 10-20 years depending on how well the tooth is maintained by the patient. Crowns are used instead of veneers in certain situations if the aesthetics of the tooth cannot be improved by veneers alone (i.e. if the tooth is too dark or too damaged). These restorations often have a greater longevity than other filling materials, and require two appointments.
