Common Causes of Tooth Staining

Dentist in Bundoora

When certain chemicals or substances stick to tooth enamel, teeth discolouration can occur. There are many colours of stains that can appear. Yellow is quite common, but stains on teeth can also be brown, green or grey in colour. The discolouration can be classified into three main categories: extrinsic discolouration, intrinsic discolouration and age-related discolouration. Fortunately, all three types can be treated by dentists who are experienced in teeth whitening in Bundoora. This article details some of the main causes of tooth staining that might necessitate professional teeth whitening treatment. 

Extrinsic Discolouration

Extrinsic discolouration or staining is caused when the outer layer of the tooth or the enamel is stained by food, dark coloured drinks like tea or coffee, or smoking. Tobacco causes nicotine stains that are yellow in appearance, and the tar which is naturally dark can also cause stains

Not maintaining proper oral hygiene can also result in the accumulation of plaque, which produces bacteria and fungi that forms stains. Failing to brush and floss the teeth will allow food bacteria to settle down on teeth which can lead to discolouration. Sometimes, brushing too hard or using an acidic mouthwash may wash away a thin enamel layer, exposing the dentine to staining. To maintain good dentine, a general dental check-up every six months is recommended. During your check-up, you can also ask your dentist about teeth whitening in Bundoora to remove any extrinsic staining that may have previously occurred.

Intrinsic Discolouration

Intrinsic discolouration is caused when the inner layer of the tooth is dark or has a yellow tint. There are several causes of intrinsic discolouration, including extreme exposure to fluoride during childhood and excessive consumption of tetracycline antibiotics by children under the age of 8 years old. 

Intrinsic discolouration is more difficult to remove and needs professional treatment. Dentists who specialise in teeth whitening in Bundoora can provide professional teeth bleaching to effectively minimise the appearance of intrinsic stains on the teeth. 

Age-Related Discolouration

As a person ages, the surface of the dentine starts to turn yellow over time. Both intrinsic and extrinsic factors can cause discolouration for age-related teeth stains. The dentine becomes weaker and the enamel that protects teeth becomes thinner, which allows food and drink particles to accumulate and cause discolouration. Regular professional tooth whitening is recommended to minimise age-related staining and keep teeth looking bright and white. 

Other Factors

Failing to maintain healthy dental hygiene may result in severe discolouration and harm to the dentine, so it’s important to brush your teeth regularly. Some diseases can also affect the colour of the teeth, plus medications for high blood pressure, diabetes and other diseases can result in teeth discolouration. Additionally, trauma to the teeth such as a fall during childhood may cause discolouration later in life. Dentists who offer teeth whitening in Bundoora can help to determine the cause of your tooth discolouration and provide teeth whitening to whiten your teeth and give you a smile you can be proud of.
