Should you believe the hype about whitening strips? What you need to know

In a smile-obsessed culture, the teeth whitening strip entered the lexicon of every home. Promoted as a cost-effective and easy means of removing stains and brightening teeth, the adhesive strips provide an alternative to professional whitening treatments, but just how good are they?

A teeth whitening strip (Bandelette Blanchissante Dents) usually consists of a thin strip coated with a layer of hydrogen peroxide or ceramide peroxide, both of which work as active ingredients to penetrate the tooth enamel to dissolve surface stains caused by coffee, tea, red wine, smoking, and other factors. The strip sticks to your teeth for a specific amount of time — typically 15 to 30 minutes per session — and is applied daily throughout one to two weeks.

Results vary, but many users see noticeably whiter teeth after only a few applications. But keep in mind that not all strips are the same. Factors such as the concentration of the bleaching agent, how well it sticks, and even the design of the strip itself can influence results. Some will only whiten the front and ignore the sides, and if not placed correctly, others will simply slip out of place.

However, there is one caution to keep in mind when you are using a teeth whitening strip, and that is tooth sensitivity. The second problem with whitening is that it can cause sensitivity during treatment and/or afterwards, whilst the peroxide diffuses through to the innermost dentin layer. To reduce this risk, seek out strips with lower peroxide levels or formulations designed for sensitive teeth. It’s also a good idea to spread out treatments or use a toothpaste with fluoride to fortify enamel.

Despite these drawbacks, strips are one of the easiest at-home whitening options available. Much cheaper than in-office procedures, they can often be used sitting in your home, even while you are carrying out your daily chores. That said, they work best on mild to moderate stains. It may not respond as well to some in-office procedures if the discoloration is deep and caused by medication, trauma, or fluorosis.

For best results, be sure to adhere to instructions closely — both for safety and effectiveness. Using a teeth whitening strip too often can result in enamel erosion and gum irritation. Additionally, good oral hygiene habits and avoiding foods and drinks that can lead to staining also help to prolong your results.

Ultimately, teeth whitening strips (Bandelette Blanchissante Dents) provide a straightforward, inexpensive way to enhance your appearance, especially when you use them properly and consistently. Although not as effective as the dramatic results of clinical treatments, they are still an option for many people who are looking to whiten their teeth without breaking the bank.
