Your teeth can become discoloured by stains on the surface of your teeth and sometimes it’s because of changes inside the tooth that are causing the problem.
Main Causes of Discoloured Teeth
- Your teeth become stained due to day-to-day activities over a long period of time such as drinking tea, coffee, colas, red wine and smoking.
- Incidents in your childhood like using certain antibiotics when you were young, too much exposure to fluoride or the after effects of injury and trauma.
- The ageing process causes dentin to naturally yellow over time. Also the enamel that covers your teeth gets thinner with age allowing the dentin to show through.
Treating Tooth Discolouration
Some tooth discolouration can be removed by professional cleaning such as the stains caused by coffee. However, many stains are permanent, and the treatment range from whitening with a bleaching gel to dental crowns or porcelain veneers if the discolouration is severe.
