What is tooth discolouration?

Tooth discolouration refers to the staining or changing of the natural colour of your teeth. This can happen for various reasons and may manifest as yellowing, browning, or greying of the teeth. 

What are the common causes?

It’s important to understand the specific cause of tooth discolouration to best determine the appropriate treatment. The most common causes include:

Staining Foods and Beverages

Eating certain foods and drinks can lead to staining on your tooth. Examples include coffee, tea, red wine, berries, and deeply pigmented foods.

Tobacco Use

Smoking or chewing tobacco products can cause yellow or brown stains on your teeth. Nicotine and tar (present in tobacco) can contribute to discoloration.

Poor Oral Hygiene

Inadequate brushing and flossing can cause tooth discoloration over time, allowing plaque and tartar to accumulate in the mouth.


As you age, the enamel on teeth naturally wears down, revealing the yellowish secondary layer (dentin)underneath. This can result in a change in tooth colour over time.

Genetic Factors

Some patients may have a genetic predisposition to certain tooth colours. This can lead to changes in tooth colour among family members.


Certain medications, such as tetracycline antibiotics (especially when taken during tooth development in childhood), can cause staining. Other medications like antihypertensives and antipsychotics may also contribute to tooth discolouration.

How do dentists treat discoloured teeth?

Our dentists use various treatments to address discoloured teeth. However, it would depend on the cause and severity of the discolouration. Here are some common remedies for whitening teeth:

Teeth Whitening

This is a popular and effective method for treating tooth discolouration. At Kedron Family Dental, we offer the option of either in-clinic whitening treatments or take-home kits. These treatments use peroxide-based agents to break down and lighten stains on the enamel.

Dental Bonding

For minor discolouration or small chips, we may recommend dental bonding. This involves applying a tooth-coloured resin to the affected tooth and shaping it to match the natural tooth colour. It is then hardened with a special light.

Porcelain Veneers

Veneers are thin, custom-made shells that are bonded to the front of teeth. They can be used to cover severe tooth stains, as well as correct issues like chips and minor misalignments.

Dental Crowns

In cases of extreme discolouration or damage, a dental crown may be recommended. These caps cover the entire tooth, providing both aesthetic improvement and structural support.

When should you see a dentist for tooth discolouration?

If you observe any notable changes in the colour of your teeth,we recommend speaking to a dentist directly. Sudden changes in tooth colour, stubborn stains despite diligent oral care, and  pain or heightened sensitivity are all indicators that warrant professional attention. Sudden discolouration may be linked with underlying dental issues that require immediate intervention. 

If you notice discolouration in a child’s teeth or have concerns about the development of adult teeth, you should consult with a paediatric dentist or a general dental practitioner. Regular dental check-ups can also help identify the root causes of tooth discolouration and allow time for intervention to maintain optimal oral health.

What our patients say

Google Review

On my recent visit I took my little boy for his first dental experience. The staff were wonderful and hygienist Alex did an amazing job of making him feel comfortable and ensuring he had an enjoyable experience. He had no complaints and even talks about when we will go back to the dentist. As my dental experience as a child was terrible, I could not recommend Alex and the team highly enough for a visit for children to make them comfortable and a positive experience.

I went for a routine check up and clean as a new customer to the practice. From checking in (Abby) to the clean (Dr Chantal and Kian), everyone was very professional and thorough. A very comprehensive assessment was made and a meticulous clean was provided by Dr Chantal. Overall great dental experience and I will be back.

I am a white knuckle dental patient (a product of school mobile dental care back in the 1960’s) I had a crown installed all in one visit today (less than 3 hours). Totally painless. All staff were wonderful and highly empathetic to my issues. The practice is highly recommended, which is why I have been a patient at Kedron for the last 15 years.

I would definitely recommend Kedron family dental. The staff are first class.
Despite my fears, they definitely were calm and collected. Which helped me be calm too. I really appreciate the work of Dr Pj and assistant Gemma.
First class!! Thank you!!

I have been going to Kedron Family Dental for a while now and such positive experiences so far at the practice. Dr Chantal and the dental assistants that work there are fantastic - professional and takes good care of your oral health. I would keep going back despite having moved to the other side of the river :))

Elwynn has been my dentist for many years, and without a doubt is one of the best! Extremely professional and knowledgeable; but where he is really ahead of the rest, is the care and explanation he provides throughout any treatment or examination. Great to have him in the Brisbane area!
