Instead of worrying over achieving perfection, one should be more concerned about attaining a consistent hue throughout one’s set of teeth. Things you will have to consider is the original shade of your teeth, which can be off-white. Usually in the case of teeth staining, there are one or several teeth that are more heavily stained than the rest.
What you should focus on is removing the heavy stains on these particular teeth. This kind of stain is called the “superficial stain” or extrinsic stain which can be easily removed by visiting your dental hygienist. After which, you can seek to whiten your whole set of teeth to a uniform, pristine whiteness.
However, one should not wait till a stain becomes too severe. Harden plaque tends to build up with time. Stains such as these will be the stubborn sort of stain that become harder to remove. The best prevention against stains is to use a powerful electric toothbrush to clean your teeth twice daily with a whitening, low abrasion toothpaste. I highly recommend that you use the Rembrandt Premium Whitening Mint Toothpaste with Fluoride. Its a very gentle toothpaste with no preservatives, artificial sweeteners, colors or flavors. And it helps to prevent canker sores too!
You may want to avoid abrasive toothpastes because they may cause tooth erosion and create tiny pockets in your teeth which then become breeding grounds for bacteria. Being thorough with your electric toothbrush regime is always a good idea. Be extra careful to go over areas that are more prone to staining such as the front teeth and the back molars.
Many electric toothbrushes also come with different types of attachable heads for various functions such as whitening or polishing. One such electric toothbrush is the Philips Sonicare R732 HealthyWhite Power which comes with an extra whitening mode. These toothbrush heads are good for occasional use to whiten teeth your teeth but daily usage might do more harm than good. Such whitening or polishing heads can be abrasive.
It is best to use them for stubborn stains and for a weekly polish. As for daily brushing, it is better to stick to a regular brush head with your electric toothbrush. Using an electric toothbrush or the best sonic toothbrush is highly recommended as it boosts a higher than normal brushstrokes per second. This means that you are cleaning your teeth more effectively compared to the traditional mode of brushing.
