Factors That May Affect the Color of Your Dentine

Drinks and food

Examples of significant staining culprits include red wine, coffee, and tea. They have color pigments known as chromogens that discolor the enamel.


It contains tar and nicotine that cancause stubborn stains. Nicotine is colorless, but when it reacts with oxygen, its color changes to a staining yellow, while tar has a dark appearance.


Dentin is a soft area located below the enamel. As we grow old, brushing thins out the outer enamel layer, which exposes the dentin underneath. This gives your teeth a yellow-appearance.


Getting hit in the mouth may make the tooth change color because its reaction to an injury is laying down more dentin.


Some high blood pressure medications, antihistamines, and antipsychotics can result in tooth darkening. Teeth might also darken due to chemo therapy and head and neck radiation.

Teeth Whitening Options

Due to the availability of different products and teeth whitening treatments, it can be challenging to decide on which ones to settle for.

Whitening methods are grouped into three general categories:

  • Administered by the dentist
  • Home whitening kits dispensed by the dentist
  • Made at home or obtained over the counter with no oversight from the dentist

The following factors might influence your decision when choosing a whitening method:

  • Type of discoloration
  • Treatment cost
  • Age
  • Dental history, including crowns and fillings

Before trying whitening methods, you should first discuss it with your dentist. The dentist will recommend a treatment plan that suits your needs.

The treatment you choose to whiten your teeth and the type of discoloration determine the time it will take your teeth to become lighter.

Professional Teeth Whitening

The dentist can use various methods to lighten your teeth at home or in the office. Most treatments use carbamide peroxide to bleach the teeth. It breaks down to urea and hydrogen peroxide, and during the chemical reaction, it targets the color of the tooth.

In-Office treatment

This type of treatment works very quickly, and its effect can last longer. Usually, the treatment takes about an hour. However, in some cases, you may require a few visits to lighten your teeth. This is because applied products contain a higher concentration of hydrogen peroxide than the products people use at home.

Dentists recommend in-office treatments to patients with abfraction lesions or receding gums.

When applying the lightening product to the teeth, the dentist might use light to help speed up the process.

At-Home treatment dispensed by your dentist

The dentist will make custom-fittrays that can perfectly fit in your mouth. Add the gel to the tray and wear it. You should stay with the tray on for about 30 to 60 minutes every day, depending on the dentist’s instructions.

Ways to Prevent Tooth Stains

Limit staining beverages and food

Coffee, dark berries and soda are known for staining teeth. You don’t have to avoid them entirely; limit the amount of time they contact the teeth.

Drinking beverages with a straw prevents direct contact with the teeth.

Brush your teeth immediately after consuming such types of foods.

Limit your sugar intake

High sugar consumption supports the growth of bacteria, which in turn causes gingivitis and plaque. Brush often after eating sugary foods.

Ensure your diet has plenty of calcium

Some tooth discoloration is a result of erosion of the enamel. Calcium-rich foods like cheese, milk, and broccoli might help protect the teeth from corrosion.

Brush and floss regularly

Tooth discoloration can also result due to plaque buildup.Brushing and flossing reduce bacteria in the mouth, thus preventing plaque buildup.
