DO YOU KNOW WHY YOUR TEETH STAIN OR DISCOLOUR?


Teeth can stain or discolour from the food or drink we consume. If a food or drink can stain or discolour your tongue or clothes it will do the same to your teeth.

To reduce staining or discolouration to your teeth, rinse your mouth with water soon after consuming, than wait 30 minutes before brushing. A professional clean will remove external stains while professional teeth whitening will lighten natural tooth colour. For a long term solution you should consider limiting tooth staining foods and drinks or look for alternatives.





A grey discolouration to a tooth may be an internal issue such as dead nerve tissue. This is quite common following trauma to your teeth or a deep cavity.

Schedule an appointment with your dentist if you notice a change in colour to a tooth.








White spot lesions can be a sign of early tooth decay. Your dentist may be able to help you prevent this from turning into a cavity.






Tooth enamel wears with age and becomes thinner allowing the underlying dentine surface to shadow through. Dentine is naturally yellow in colour which is why mature teeth don’t look as bright and white as younger teeth. Professional teeth whitening can lighten the shade of your natural teeth.
