How Do You Fix Teeth Discoloration? (And Why It Happens)

Your teeth are one of the first things people notice about you, so it’s important to keep them looking their best. Unfortunately, over time, teeth can become stained and discolored.

Here are a few things about teeth discoloration you should know about.

Types of Staining

There are two types of staining: extrinsic and intrinsic.

Extrinsic staining occurs on the surface of the teeth and is usually caused by things like food, drinks, smoking, or aging. This type of staining is usually easier to treat because it only affects the outer layer of the tooth. 

Intrinsic staining occurs when the stain goes deeper than the outer layer of the tooth. This type of staining is usually caused by things like trauma, certain medications, or certain medical conditions. Intrinsic staining is usually more difficult to treat because it affects the inner structure of the tooth.

Major Causes of Teeth Discoloration

There are many things that can cause teeth to become discolored. Some of the most common causes include:

Aging: As you age, the outer layer of your teeth (enamel) starts to wear away, exposing the inner layer of your teeth (dentin). Dentin is yellow in color, so when it’s exposed, it can make your teeth look yellow.

Trauma: An injury to the tooth can cause it to become discolored.

Medications: Certain medications, such as tetracycline antibiotics, can cause teeth to become discolored.

Medical Conditions: Some medical conditions, such as tooth decay, can cause teeth to become discolored.

Smoking: Smoking is one of the leading causes of teeth discoloration. The nicotine and tar in cigarettes can cause the teeth to become stained.

Poor Oral Hygiene: Poor oral hygiene can lead to a build-up of plaque and tartar on the teeth, which can cause them to become discolored.

How to Fix Teeth Discoloration

Fortunately, there are things you can do to help reverse or prevent teeth discoloration. Some of the best ways to fix teeth discoloration include:

Avoid Eating Staining Foods

The first step to fixing teeth discoloration is to avoid eating staining foods. Foods like coffee, tea, soda, red wine, soy sauce, and curry can all cause teeth discoloration. If you can’t avoid these foods altogether, then at least try to brush your teeth immediately after eating them.

Regular Cleanings 

Regular cleanings are important for keeping your teeth healthy and white. During a cleaning, your dentist will remove any plaque and tartar from your teeth. Plaque is a sticky film of bacteria that forms on your teeth. Tartar is hardened plaque that can only be removed by a dentist.

Teeth Whitening 

Teeth whitening is a popular way to fix teeth discoloration. There are many different ways to whiten your teeth, including at-home kits, in-office treatments, and over-the-counter products.


Veneers are thin pieces of porcelain that are bonded to the front of your teeth. Veneers can be used to cover up any type of tooth discoloration.

Full Mouth Restoration 

Full mouth restoration is a comprehensive treatment that can be used to fix many different dental problems. Full mouth restoration can include treatments like veneers, teeth whitening, and dental implants.


There are many things that can cause teeth discoloration, and it’s important to be aware of all the possible causes. Some of the more common causes include drinking coffee or tea, smoking cigarettes, and eating certain foods. There are also some medical conditions that can cause teeth discoloration.

If you are concerned about your teeth discoloration, it’s a good idea to talk to your dentist. They can help you determine the cause of the discoloration and recommend the best treatment options.
