Teeth Whitening Q & A
What causes a tooth to change color?
Teeth can become stained over time, even when you practice the best dental hygiene. A tooth has four major components: cementum, pulp, enamel, and dentin. When it comes to tooth discoloration, enamel and dentin are usually the culprits.
Enamel is the hard, clear exterior designed to protect the tooth. Beneath the enamel is dentin, the yellowish interior of the tooth that adds to its longevity. A discolored tooth is the result of either stained enamel or more pronounced yellow dentin.
Why are my teeth discolored?
Teeth become discolored for a variety of reasons, including:
The tar and nicotine found in tobacco cause stains; nicotine becomes yellow when mixed with oxygen, and tar is naturally a dark color.
Food and drinks
Do you drink coffee, tea, or wine? These popular beverages have color pigments called chromogens that bond to the enamel of your teeth and cause staining.
Trauma to the tooth
A tooth can change color if it has experienced trauma because it produces more dentin in response to the injury.
Some medications, including those for high blood pressure, antihistamines, and antipsychotics, can cause discoloration. Additional medications that pass from mothers to their babies while their teeth are forming can cause them to have discolored teeth as adults.
As you age, enamel grows thinner and allows the yellowish dentin underneath to show through.
Can all teeth be whitened?
If stained enamel causes your tooth discoloration, you may be a good candidate for teeth whitening. Teeth that are discolored because of dentin usually do not respond to traditional whitening procedures.
After an initial exam, cleaning, and consultation, Dr. Mannan can determine whether you’re a good candidate for teeth whitening.
