Professional vs. Store-Bought Teeth Whitening Products and Their Ingredients

Stains often occur on teeth over time, as foods and beverages can eventually cause discoloration. Consumers may scan store shelves to find a product that will give fast and effective results, but it's helpful to compare the differences between professional and store-bought teeth whitening products and their ingredients.

Ingredient Comparisons

The two active ingredients in whitening products are hydrogen peroxide and carbamide peroxide. Of these two agents, carbamide peroxide is often preferred, as it is slightly more stable than hydrogen peroxide and it penetrates teeth more gradually.

Home vs. Professional Applications

Over-the-counter products contain up to 10 percent hydrogen peroxide. Professional products contain a combination of both active agents. Hydrogen peroxide levels rise to 40 percent for professional teeth whitening applications, with carbamide peroxide levels at about 35 percent. 

Consumers should contact a dentist for a professional recommendation regarding this process. Some people may need the extra brightening power of a professional application, while others might find success with a product purchased over the counter.
