When choosing products from the store or from your dentist to get whiter and brighter teeth, you may wonder how these products can get the job done. While there are many different types of products, they generally work to whiten the teeth in one of two ways. These are through abrasion or lightening.
Many products that you can buy over the counter will work by the abrasion method. Small particles scrub away surface stains to reduce discoloration caused by foods, beverages, and lifestyle choices. However, abrasive materials can only do so much and may actually be damaging to the teeth if used improperly over time.
Gels, trays, and strips may use peroxide to help remove stains from beneath the surface of the teeth for actual whitening effects. The peroxide can work inside of the teeth to lift away particles that cause discoloration.
Your dental care provider can offer products that are much stronger than those that you can purchase at the store. This can help you to achieve greater results in a shorter time frame. Because of the risk of irritation to gums and sensitivity to the teeth, it is important that a qualified dentist be the one to use these teeth whitening treatments.
