Types of Teeth Stains

June 14, 2022

One of the common questions patients ask their cosmetic dentist in Pembroke Pines is about teeth whitening methods. They want whiter, brighter teeth, but most of them do not know why their teeth have become discolored or stained in the first place.  

Extrinsic and intrinsic stains are the two types of stains that cause tooth discoloration.  Once this happens, the necessity for teeth whitening arises. Let’s look at the different types of tooth discoloration in more detail.

Causes of Teeth Discoloration

Intrinsic Stains

This type of stain develops beneath the surface of the teeth, in the dentin. Teeth whitening solutions can’t remove this stain. They’re usually a sign of something more serious. Dental decay, excessive fluoride ingestion, and an accident could cause brown stains deep within the tooth. If tooth whitening fails to remove the stains, dental veneers are another alternative. 

Extrinsic Stains

Extrinsic stains are also known as superficial stains since they form on the tooth’s surface. Consumption of various staining products might result in stains such as light brown patches and uneven yellowing. They may be due to tobacco, wine, and coffee. Some fruits like pomegranate, raspberries, and other berries can also cause teeth stain. Professional teeth whitening and fluoridated toothpaste can help eliminate and reduce these stains. 


Teeth will yellow and darken as they age, which is a natural part of life. The discoloration could also be caused by bruxism. The dentin layer of the teeth gradually increases over time, resulting in yellowing teeth. When teeth are subjected to stress, such as grinding, the dentin responds by developing more quickly. 

White Spots

When white spots appear on a tooth’s surface, it usually means the tooth is in the early stages of decay. When compared to the rest of the tooth, the white area may appear dull and etched. Bacteria and acid are demineralizing the enamel, which will eventually result in a cavity. Extrinsic stains from coffee, tobacco, and other staining products can also be picked up by the white spots.
