Dazzling to Dull
White teeth or the natural shade that you remember from your younger years, can darken or yellow over time. Most importantly, to maintain a dazzling smile, you need good home care and regular dental visits. Flossing daily and brushing with a whitening toothpaste that contains peroxide and/or baking soda, can help you keep your teeth looking their whitest by helping to remove plaque and surface stains. Lifestyle factors can cause staining to occur intrinsically or into the deeper layers of the tooth. These can include side effects from medications and medical treatments, as well as from tobacco use.
Also any trauma, like bumping or dislodging a tooth can cause a tooth to darken over time. Of course, some of your favorite beverages, like coffee and red wine, will dull and darken your smile by penetrating the enamel over time. Teeth can also darken without any external factors, simply just from aging. As you age, the enamel layer covering the tooth can become thinner allowing the darker layer underneath, the dentin, to become more prominent. Whitening treatment will depend on the existing shade of the teeth and the contributing factors and the final shade that the patient desires.
Bleaching Choices
What are the options for a whiter smile? Based on your dentist's advice, it will entail either an office dispensed whitening kit, an in-office procedure or an over-the-counter product, all of which are easy processes. The active ingredient is either hydrogen or carbamide peroxide that can range from 10 to 22 percent in strength for professional treatments. Typically, the simple case that desires only a few shades lighter can be achieved with a product available at a local drug or discount store and done at home. These products can include strips, pastes or gels.
In-office procedures can be done in as little as five minutes or up to an hour, depending on the process. Perhaps the most common and effective treatment is having custom trays made from an impression of your teeth at your dental office. Then you bleach at home with a high concentration bleach material dispensed by your dentist, who will closely monitor you during the process. There can be some temporary sensitivity in the teeth while bleaching and your dentist or dental hygienist can make suggestions to reduce this side effect.
