Everyday wear and tear and ageing can cause natural yellowing, or darkening of teeth. Commonly staining of teeth occurs due to the accumulation of plaque and calculus on teeth. Other factors such as tea and coffee, smoking, and some medications can cause what is called extrinsic staining and more often than not can be removed with thorough hygiene and professional cleaning.

Home care can work toward preventing staining caused by the build-up of plaque and calculus however more persistent staining and discolouration may require professional attention and may be treated with whitening treatment or veneers.

Decay and cavities, whether new or beneath existing fillings are another common cause of dental discolouration (Pictures).

Especially if accompanied with sensitivity, bleeding around the gums or pain it is important to make an appointment with our dentists as these may be a sign that the dental nerve is being affected and at a high risk of infection requiring a filling or more extensive treatment such as root canal therapy.

A tooth that has a grey, black or reddish hue (Pictures) may also be a sign that the tooth nerve is infected and may require root canal therapy. If the tooth already has had a root canal therapy, retreatment, internal bleaching or a crown may be options to address the discolouration.

Internal bleaching is a treatment where a tooth with a root canal is lightened to remove dark grey discolouration associated. Part of the root canal filling is removed and a whitening medication is placed inside the tooth. 1 week later
