ToothBleachingTestYourKnowledge

Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?

1. Bleaching?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.

2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.

3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.

4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.

5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.

6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.

7. Tetracycline?
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.

8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.

9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.

10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
