Intrinsic vs. Extrinsic Tooth Stains: Your Teeth Know the Difference
Having a bright and white smile is easier said that done. So many substances can cause tooth discoloration and stains, and they may be hard to avoid. Thankfully our Los Algodones, Baja California cosmetic dentistry practice offers comprehensive treatment options designed to address tooth discoloration and stains.
There are, generally speaking, two kinds of dental stains. Let’s take a moment to compare extrinsic dental stains and intrinsic dental stains.
About Extrinsic Tooth Stains
Extrinsic tooth stains are stains that occur on the surface layer of the teeth. Food, beverages, and other substances wind up staining the color of your tooth enamel, resulting in a dingy, darker, smile. Usually extrinsic tooth stains appear yellow or brown in color.
Causes of Extrinsic Tooth Stains
The most common causes of extrinsic tooth stains include:
- Chewing tobacco
- Soft drinks
A good rule of thumb is that if it can stain a white sheet, the substance can probably also stain your teeth.
Treatments for Extrinsic Tooth Stains
To treat extrinsic tooth stains, the following treatments are most common:
- Teeth Whitening - Teeth whitening is a process in which the tooth enamel is bleached with a whitening agent. This eliminates the stain, allowing you smile to look bright and clean again. A single professional teeth whitening session may be able to brighten your smile by several shades.
- Dental Bonding - Dental bonding refers to the use of tooth-colored dental resin that is painted directly onto your teeth. This dental resin conceals flaws underneath, allowing your smile to look pristine.
- Porcelain Veneers - Porcelain venters are thin shells of dental ceramic that are adhered to the front of a tooth. With a porcelain veneer in place, the stain is completely masked and hidden from view, giving your smile a natural appearance.
About Intrinsic Tooth Stains
Intrinsic tooth stains are stains that originate from within a tooth. These kinds of discoloration are usually the result of injuries to a tooth or other issues that do not involve external exposure to stain-causing substances.
Causes of Intrinsic Tooth Stains
Some of the most common causes of intrinsic tooth stains include:
- Trauma to a tooth
- Excessive fluoride exposure
- Overuse of tetracycline and other antibiotics
- Genetics and family history
Treatments for Intrinsic Tooth Stains
Topical bleaching will not be able to treat intrinsic stains, so other kinds of dental treatments are more viable. These include:
- Dental Bonding - By painting a tooth-colored resin over a stained tooth, the discolored inner material can be hidden from view. This is ideal for minor intrinsic stains.
- Porcelain Veneers - The concealing nature of porcelain veneers proves essential for treating intrinsic stains. With a porcelain veneer in place, the discord tooth structure is difficult to notice, and the surface of the tooth looks totally natural.
- Dental Crowns - For major stains, the most ideal option may be a dental crown. Dental crowns are caps that fit over a tooth, protecting it from harm and improving the appearance in the process. A porcelain crown may be just right for a major intrinsic stain.
