  • Methods for Transforming Stained Teeth

We are constantly exposed to images of celebrities with pearly white teeth or ads for tooth whitening products. Contrary to popular belief, teeth are naturally slightly yellow in colour. Dentin, the tissue beneath the enamel of the tooth, is tinted slightly yellow.

But more severely discolouration could be a sign of underlying health problems or poor hygiene and habits though. There are several ways to prevent and reverse staining for a whiter smile.

Types of Teeth Staining

It is important to understand the cause and type of teeth staining you have to understand the best method of treatment.

  • Extrinsic staining: When thinking about tooth staining this is what people usually think of, and is the easiest to reverse. Extrinsic, meaning outward, stains are on the surface of the tooth enamel. This type of staining is usually caused by food, drinks, and smoking.
  • Intrinsic staining: This type of staining is below the tooth surface, and more difficult to remove than extrinsic stains, but not impossible. These types of stains are usually caused by trauma to the tooth or tetracycline staining.
  • Staining with age: Dentin naturally darkens with age. This, paired with the prolonged effect of food, beverages, and smoking on the teeth, cause them to become more yellow as we age.

How to Prevent Stained Teeth

The preventative measure is almost always easier than the cure. Proper care and avoiding certain things that cause teeth staining can help maintain the state of your smile.

1. Food and Drinks

Certain foods and drinks are known to stain and corrode tooth enamel. For whiter teeth, you should avoid the following:

  • Soda
  • Coffee
  • Black tea
  • Red wine
  • Candy and sweets

Most people already know the correlation between these things and teeth staining, and are not willing to give up their coffee for the sake of whiter teeth. Be mindful of what you are eating or drinking and when possible, brush your teeth immediately after consuming tooth staining foods or drinks.

When it is not possible to brush immediately after, swish some water in your mouth so staining agents aren’t sitting on your teeth. Also, using a straw and swallowing drinks swiftly can help keep them off your teeth.

2. Avoid Tobacco

As well as other detrimental health effects, both cigarette smoking and chewing tobacco stain teeth. Nicotine itself is colourless but combined with oxygen turns yellow. Chewing tobacco stays in the saliva and on the teeth, causing staining.

Tobacco use is also directly linked to gum disease. Smokers are at twice the risk of non-smokers for gum disease. Tobacco stains are often difficult to remove because they are deeply settled after years of smoking, but they can be removed with professional whitening.

3. Regular Brushing and Care

Lack of proper oral hygiene can lead to plaque and tartar build up and leave food and drinks to sit on the teeth, causing them to yellow. Brushing twice a day with a soft-bristled electronic toothbrush is recommended for adequate tooth cleaning. Also, flossing will help prevent staining in between teeth where it is hard for a toothbrush to reach.

Whitening toothpastes and mouthwashes can help aid in speeding up the process of removing stains. Also, baking soda acts as a natural tooth-whitening agent, but be careful and use in moderation. Using too much baking soda can be too abrasive and wear away at the enamel and cause sensitivity issues.

4. Professional Teeth Cleanings

Brushing your teeth removes plaque, but a build-up of plaque can lead to tartar, which can only be removed by a professional dental hygienist. You should get your teeth cleaned every six months. Dental hygienists use special tools to scale and polish each tooth. After a cleaning you may even notice your smile looks brighter and feels smoother.

Teeth Whitening Solutions

Preventative measures can help slightly whiten teeth and prevent further staining, but there are several options for fast results to whiten stained teeth.

1. Professional Whitening

The most effective method of whitening teeth and removing stains is a professional tooth whitening treatment. Lasers and LEDs with a concentrated amount of bleaching products are used to significantly whiten in only one visit. There are a variety of different professional whitening treatments out there. You can consult with your dentist on the best option for you – contact the Valley Ridge Dental Centre to learn more.

It is important to note that most methods of professional whitening are only effective on extrinsic stains, not intrinsic stains due to trauma or tetracycline staining.

2. At-Home Tooth Whitening

At-home tooth whitening is less effective, but more affordable than in-office treatments. There are two main categories of at-home tooth whitening treatments – over the counter and professional. Over the counter treatments are a good choice to treat light staining.

Professional at-home treatments provided by a dentist consist of a custom-fit tray and a hydrogen peroxide or carbamide peroxide treatment solution. Another option for professional at home whitening is carbamide peroxide whitening gel with an LED light that accelerates the whitening gel.

3. Veneers

The previous two whitening options are effective for externally stained teeth. For deep, intrinsic stains, veneers can be the best or only option. Veneers are thin covers that adhere to the surface of the tooth. They are long lasting, natural in appearance, and do not easily stain. Another plus side to veneers is you can choose a tooth colour from an assortment of shades. Sometimes bright white smile can look fake; your dentist will help you determine a whiter, yet natural looking shade.


There are multiple options for preventing tooth stains and correcting already stained teeth. Whiter teeth can help improve your confidence, but it is good to remember that what is most important is the health and condition of your teeth.
