Teeth Discolouration

We specialise on teeth whitening and other cosmetic procedures that restore the natural brightness of your smile.

What Is Teeth Discolouration?

Teeth discolouration refers to changes in the colour of teeth from their typical white shade. It can be extrinsic, affecting the outer enamel, or intrinsic, altering the inner dentin. Causes range from dietary habits and ageing to medications and certain medical conditions. Proper dental care can help prevent and mitigate this issue.

Causes of Discoloured Teeth

Most often, discolouration happens when drinking too much or taking a certain type of drug. Other times, it can be caused by particular high in sugar or salt foods. There are also times when discolouration occurs because of a virus, bacteria or fungus. 

In addition to these causes, there are other reasons why people might have teeth discoloured – primarily if they practice certain dental hygiene habits. 

One of the most common reasons is what we eat and drink. Beverages like coffee, red wine, and tea can cause teeth to become stained. Smoking and chewing tobacco can also cause teeth to become discoloured. 

Another common reason for tooth discolouration is age. As people get older, their teeth often start to yellow. 

The Most Common Reasons for Discoloured Teeth

  • Tooth decay: This is a common cause of tooth discolouration. When tooth decay is left untreated, it can cause the tooth to become black or brown.  
  • Tooth wear: This is caused by grinding your teeth, using your teeth to open bottles or cans, or using them to chew on complex objects. Over time, this can cause the teeth to become yellow or brown.
  • Tobacco use: Tobacco can cause the teeth to become yellow, brown, or black.  
  • Food and drink: Foods and drinks high in colours, such as coffee, tea, and red wine, can cause the teeth to become discoloured.
  • Alcohol use: regular intake of alcohol can cause tooth discoloured.
  • Cannabis use: also called marijuana or weed. It can lead to an increased risk of teeth discoloured and gum problems. 

Bad Dental Hygiene Causes Teeth Discolouration

While most people know that bad dental hygiene can cause various health problems, only a few people understand the direct link between bad dental hygiene and tooth discolouration. 

This phenomenon is called dental fluorosis. It is caused by high levels of fluoride in municipal water supplies (and thus fluoridated water). Unfortunately, most people don’t realise that fluoride is a hazardous substance and can cause serious health problems. 

Dental fluorosis is the most visible form of tooth discolouration, but it isn’t the only one. There are many other forms too. These include: 

  • dental xerostomia: in which the teeth have become so damaged that they are no longer covered by enamel (it’s like having a hole in your mouth);
  • papillary fibrosis: which occurs when teeth become abnormally white;
  • enamel hypoplasia: where the enamel has been damaged; 
  • algogenic staining: occurs when coloured areas are present on the teeth due to weak enamel (this colouring may be yellow or red).

Once you have tooth discolouration, it usually takes several months to go away completely (which is why it’s important to speak with your dentist about what might be causing it). The simplest way to help speed up this process is with regular dental visits from your dentist.

How Do Dentists Treat Discoloured Teeth?

Professional Teeth Whitening

This is often the first line of treatment. Dentists can remove surface stains that regular home cleaning can’t manage, restoring your teeth’s natural colour.

Teeth Whitening

For persistent extrinsic stains, your dentist might recommend a professional whitening treatment. This procedure involves the application of a bleaching agent to the teeth and can significantly brighten your smile.

Dental Veneers

If discolouration can’t be corrected with cleaning or whitening, veneers may be an option. These are thin, custom-made shells designed to cover the front surface of your teeth, giving them a more classic, white appearance.

Dental Bonding

In this procedure, a tooth-colored resin is applied to the teeth and hardened with a special light. This bonds the material to the tooth to improve its appearance.

Dental Crowns

For severe discolouration, a dentist might suggest a crown, which fully covers a tooth, restoring its normal shape and appearance.

How To Prevent Discoloured Teeth

While there are many ways to whiten teeth, preventing them from discolouring in the first place is always the best option. Here are a few tips on how to avoid teeth discolouration:

1. Avoid eating or drinking dark-coloured beverages and foods

Some of the most common culprits of teeth discolouration are dark-coloured beverages and foods. The natural pigments in these foods and drinks can stain teeth over time, leading to yellow or brownish discolouration. To prevent this, try to avoid drinking or eating anything that is dark in colour.

2. Practice good oral hygiene habits

One of the best ways to prevent teeth discolouration is to practice good oral hygiene habits. This includes brushing your teeth at least twice a day, flossing regularly, and using a mouthwash. By keeping your teeth clean and free of plaque and bacteria, you can help prevent them from discolouring.

3. Use teeth whitening toothpaste

If you are already experiencing teeth discolouration, teeth whitening toothpaste can help lighten them up. There are many different brands of teeth whitening toothpaste on the market, so be sure to choose one that is right for you.

 However, most of these toothpastes may contain some chemicals that are pretty harmful to your teeth. Make sure to consult your dentist before getting a whitening toothpaste. 

4. Consider using a teeth whitening kit

If you want to achieve even better results, you may want to consider using a teeth whitening kit. These kits usually come with a bleaching agent, which can help to lighten your teeth up by several shades.

5. Visit your dentist for professional teeth whitening

No one does it better than a professional. If you want to achieve the best possible results, you may want to visit your dentist for professional teeth whitening. This is a safe and effective way to lighten your teeth up by several shades in a short amount of time.

By following these tips, you can help to prevent teeth discolouration and keep your smile looking its best.

What our clients say

Google Review

Have been a client here for over 10 years and highly recommend this practice. Dr Lubinka has been my dentist for 12 years since I moved from the UK. Her professionalism, knowledge, attention to detail and her communication is outstanding. The administrative, support and dental nurse staff here are equally exceptional. Customer focused, positive, flexible and polite. Have never ever considered going anywhere else. Highly recommended.

Thank you to all the staff for being so caring and accommodating for my husband's first visit. Dr Lubinka has set him on a path toward dental health recovery. This practice has even inspired me to visit for a checkup and that’s somewhat miraculous!

Google Review

Excellent customer service, with friendly and experienced staff! This is so helpful when you have a child who has always been anxious going to the dentist. Dr Master is so professional and composed that I don't even need to go in with my child when she has an appointment. He makes sure that you are completely satisfied with the service you receive and that's at no additional cost to you!

Google Review

What can you say? Who loves going to the dentist? My experience has been awesome. No pain, no fuss, friendly and professional. Do I want to go again? No. I want to take better care of my teeth. Yet, if I have to go, I definitely will be back here.

I cannot praise Mindarie Quinn’s dental staff highly enough. My son had an accident at school resulting in a chipped tooth, the desk staff were amazing, shifting around appointments to fit him in for emergency treatment. Dr Aron was brilliant. He was calm & gentle with a traumatised boy. Within the hour we were back home with a fixed up-front tooth. This is my usual dentist, and my experiences are always great, but the care we received today in an emergency was so professional and reassuring, I felt the need to leave a review of our experience. Thank you for the incredible treatment we received with you today.

Staff are always super friendly. Really helpful when it comes to dental emergencies. My teeth are forever grateful.

Myself and my children have been seeing Lubinka for years. She is kind, patient, friendly and explains everything very well. My daughter had to have 4 teeth extracted and the procedure went very well because of her trust in Lubinka. The other staff are also lovely. We highly recommend this practice.
