Common Concerns: Stained/Discoloured Teeth
About Stained/Discoloured Teeth
Stained or discoloured teeth are a common concern that can affect the brightness of your smile and impact confidence. Discolouration can occur for many reasons, including lifestyle habits, ageing, and certain medical conditions. Everyday factors such as coffee, tea, red wine, and smoking can cause external stains, while internal staining may result from genetics, medications, or excessive fluoride exposure during childhood. Over time, enamel can also wear down, revealing the naturally yellow dentin underneath.
Our experienced therapists can help identify your concerns and recommend the best approach for a brighter smile. With our teeth whitening treatment, we can help restore a whiter, more radiant look—leaving you smiling with confidence!
Signs of Stained/Discoloured Teeth
You may notice one or more of the following signs of tooth discolouration:
- Yellowing of the teeth, brown spots, or both
- Overall dull or discoloured appearance
- Discolouration affecting the outer enamel (extrinsic)
- Discolouration within the tooth (intrinsic)
Causes of Stained/Discoloured Teeth
Tooth staining can result from lifestyle factors such as frequent consumption of coffee, tea, red wine, and dark-coloured foods, as well as smoking or tobacco use. Ageing contributes as enamel naturally wears down over time, exposing the yellowish dentin beneath. Other causes include certain medications, excessive fluoride exposure during childhood, poor oral hygiene, and genetic predisposition.

Stained/Discoloured Teeth FAQs
You will start to see results from your very first treatment. For more difficult stains we recommend to have another whitening treatment 2 weeks apart for a whiter, brighter smile.
Teeth Whitening treatments are painless. Your teeth may feel a little sensitive during treatment but this is very normal. Teeth whitening treatments are also very safe and the product used does not damage your tooth enamel and will not cause any harm to your teeth or gums.
We recommend that you avoid eating & drinking acidic-coloured beverages, for a minimum 3 hours after treatment as your teeth are very absorbent. Drinking water is acceptable. You are also to avoid any food or beverages that are prone to staining your teeth i.e., red wine, coloured sauces, tea & coffee, for a minimum 72 hours post treatment.
Intrinsic staining are stains that occur below the surface of the tooth enamel. Common causes of intrinsic staining include ageing, genetics, decay, medication & trauma to the tooth. Teeth whitening treatments are not effective on intrinsic staining.
Extrinsic staining are stains that appear on the superficial surface of your teeth. Common causes of extrinsic teeth staining include drinking-coloured beverages like red wine, coffee & lifestyle habits such as smoking cigarettes. Teeth whitening treatments are most effective on extrinsic stains.
