Teeth can discolour for a number of reasons including:
- Surface staining from food or drinks such as coffee or tea and smoking.
- Poor Oral Hygiene
- As a result of trauma.
- Following root canal treatment.
- Old Stained Fillings
- From the use of antibiotics or excessive fluoride in children.
Stains on the surface of the tooth can be removed with a professional clean but will not change the intrinsic colour of the teeth.
Teeth Whitening uses a bleach to oxidise and remove the coloured compounds within teeth. It is a safe and conservative way to lighten the teeth without causing any irreversible damage. It is recommended to have an examination prior to commencing any tooth whitening. This can help assess whether you are suitable candidate and individual results can vary depending on the severity of the discolouration.
Bleaching should always be carried out under the supervision of a dentist and as such over the counter bleaching kits or bleaching performed in beauty salons are not recommended.
