Whitening 101: Your Dental Hygienist Explains Hydrogen Peroxide

Curious about how teeth whitening really works? The key is hydrogen peroxide. This isn't just a common ingredient; it’s a powerful one, used by both at-home products and dental professionals to deliver results. Hydrogen peroxide works by penetrating the tooth enamel to oxidize and break down the molecules that cause stains. When used properly and as directed by the manufacturer’s instructions, whitening products or treatments with hydrogen peroxide is an effective way¹ that will help you achieve a brighter smile.

So let's dive into the good stuff. Here's what you should know about HP:

• Addressing Different Stain Types

Discoloration can occur on the surface of the tooth (extrinsic stains) or deeper within the tooth (intrinsic stains). Extrinsic stains may be the result of common things we consume on a daily basis, especially those with strong pigments (chromogens) or high acidity. The general rule is: if it can stain a white shirt, it can probably stain your teeth.

Intrinsic stains, often caused by trauma or developmental factors, may require professional dental treatment. So depending on your needs, incorporating a whitening toothpaste into your daily routine, such as Optic White Pro-Series toothpaste, can remove up to 15 years of stains* and is a great option. Not sure which route to go? Ask your hygienist or dentist to check the shade of your teeth. From there, it’s about finding what works for you.

• Multi-Action Oral Care - A Combination of Benefits

With the basics of hydrogen peroxide & stain types under our belt, are there any other considerations that may help guide your purchase decision?

Whitening toothpastes that contain hydrogen peroxide can not only penetrate the tooth enamel to break down the extrinsic stains and some deeper, intrinsic stains, they offer a combination of benefits. The advantage of incorporating an HP Whitening Toothpaste into your daily routine, is that it is specially formulated to clean and protect your teeth while working to remove stains at the same time. They contain ingredients for fighting cavities, removing plaque, and promoting gum health, which are benefits that some whitening strip products don't offer.

Integrated into your daily oral hygiene routine, you simply use it as your regular toothpaste, twice a day, every day. This consistency is a major benefit for maintaining a white smile and provides a comprehensive approach to oral health.

• Minimizing Sensitivity

Some patients shy away from whitening as they fear it may cause an increase in tooth sensitivity. It's a common fear, often rooted in past experiences with abrasive, high-concentration formulas that can irritate teeth and gums. The key lies in a product formulated with the right concentration of hydrogen peroxide. Designed to be gentle on your teeth while still powerful enough to lift deep-set stains.

If sensitivity does occur, discontinue use and consult your dental professional to rule out other potential concerns.

• Appropriate Age for Whitening

The American Academy of Pediatric Dentistry² generally recommends waiting until all permanent teeth have fully erupted and the enamel has calcified, which is typically around 14 to 16 years of age. This is to minimize the need for localized whitening and reduce the risk of pulpal damage.

• Different Strengths, Different Results

Whitening products are available in a range of strengths, from the lower concentrations found in daily-use toothpastes to higher concentrations used in whitening pens and strongest being in-office professional treatments. The right product for you depends on what you want to achieve and how quickly you want to get there.

• What to Do About Stained Restorations

If you have stains on your crowns or bridges, a professional dental cleaning is often the best solution. A hygienist can use special tools to remove extrinsic surface stains that have built up over time. If the stains are intrinsic (from within the material itself) or the restoration no longer matches your teeth, the only way to achieve a brighter, uniform smile is to have the restoration replaced to match your new tooth shade.

• Consult Your Dental Professional

Navigating the world of whitening products can be confusing, but you don't have to do it alone. The best place to start is with your hygienist or dentist.

They can help you:

• Assess your current shade. A professional can accurately determine your starting point and discuss the realistic shade you'd like to achieve.
• Find the right strength. Based on your goals and dental health, they can recommend the best treatment for you, from professional in-office solutions to a take-home product.

Regardless of which product you choose, always follow the manufacturer’s instructions and if you have any questions, consult your dental hygienist or dentist at your next visit.
