What words do you associate with the words white teeth? Clean, welcoming, bright, and health were the first that came to our mind.
Did you know that someones smile is the first feature that most people notice when they meet you? The American Association of Orthodontics did a whole study on it.
So our smile is important. Because so many people notice smiles right away, its a good idea to keep them white people that they depict cleanliness and health.
Even perfect habits of brushing and flossing will not guarantee a smile that is as white as you would like. The American Dental Association gives some reasons why our teeth change from white to a dull effect.
Why Did My Teeth Change Color?
Over time, your teeth can go from white to not-so-bright for a number of reasons:
- Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).
- Tobacco Use
Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through.
If you’ve been hit in the mouth, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
Tooth darkening can be a side effect of certain antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
How Does Teeth Whitening Work?
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Does Whitening Work on All Teeth?
No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on caps, veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.
The remedy to the stains on your teeth is bleach. Whitening your teeth brings a purer color and shine to your smile. Teeth whitening is not a "one size fits all" concept, there are many different methods,effects, and results. Set up an appointment and talk to your Dentist to have the best and most effective experience.
