Tooth stains fall into two categories: extrinsic and intrinsic. Extrinsic stains are the yellow and brown stains that occur on the surface of your teeth. Intrinsic stains occur inside teeth, making them appear gray or blue, and they have a variety of common causes, including:
• Childhood antibiotics
• Trauma that has led to the death of a tooth’s nerve (tooth turns grey, brown, or black)
• Overexposure to fluoride when young, resulting in a spotted or mottled look
Some surface stains can be removed simply with teeth-whitening toothpastes and over-the-counter teeth-whitening kits. These stain-removal methods, along with employing a good daily oral-hygiene routine, can help you begin to revitalize your youthful smile.
• Brush and floss regularly to avoid the stains that result from plaque buildup
• Get regular professional cleanings to remove tartar and stains that result
• Avoid smoking, which not only stains teeth but damages gums
• Avoid drinks that stain (coffee, soda, wine) and drink liquids through a straw when possible to avoid contact with teeth
Things to consider:
• Choose toothpaste that has been awarded the ADA seal of approval (these toothpastes will not fix stains that are intrinsic)
• Teeth-whitening kits take about 2 to 3 weeks to get the job done
• A common side effect of teeth-whitening kits is tooth and gum sensitivity
If you have deep stains or want to achieve a brighter smile quickly, having your teeth whitened by your dental care provider is the best way to go. Professional-grade whitening products can whiten your smile by 10 to 12 shades in a very short amount of time. Setting up an appointment for a whitening consultation is the best way to find out which method is best for you.
