Why Do Whitening Strips Hurt My Teeth? | Mend Dental (2024)

• February 9, 2024

Whitening strips have become a popular choice for achieving a brighter smile at home. While these strips offer a quick and affordable solution, some users may experience tooth sensitivity or discomfort. In this article, we explore the reasons behind the question, “Why do whitening strips hurt my teeth?” and provide insights into how whitening strips work, potential causes of sensitivity, and ways to prevent or relieve the discomfort.

How Whitening Strips Work

Whitening strips consist of thin, flexible plastic coated with a gel containing hydrogen or carbamide peroxide – the key ingredients responsible for teeth whitening. These peroxide compounds penetrate the enamel, eliminating surface stains and lightening the tooth colour. Although whitening strips are known for their effectiveness, improper use or overuse can lead to temporary or prolonged teeth sensitivity.

Causes of Teeth Whitening Sensitivity

Several factors contribute to the sensitivity experienced after using whitening strips:

• Concentration of Whitening Agent: The concentration of peroxide in whitening strips can impact sensitivity. Higher concentrations may lead to increased sensitivity.
• Improper Usage: Incorrect application or leaving the strips on for an extended period can contribute to sensitivity issues.
• Frequent Use: Overusing whitening strips, such as applying them more frequently than recommended, can increase the risk of sensitivity.
• Pre-existing Dental Issues: Individuals with pre-existing dental concerns, such as naturally sensitive teeth or weak tooth enamel, may be more prone to sensitivity after using whitening strips.

Are Whitening Strips Bad for Your Teeth?

While whitening strips can be effective when used as instructed, prolonged or excessive use may lead to potential risks. Prolonged exposure to peroxide can weaken tooth enamel, increase sensitivity, and contribute to issues like cavities and gum irritation. It’s crucial to be aware of potential side effects and discontinue use if persistent sensitivity occurs. Seeking advice from a dentist can help address concerns and ensure safer whitening practices.

Ways to Relieve Tooth Sensitivity After Whitening

• Speak to Your Dentist: Before using whitening strips, consult with a dentist to assess your dental health and receive personalised recommendations to minimise potential side effects.
• Choose Lower Peroxide Concentration: Opt for whitening products with lower peroxide levels and shorter application times to reduce the risk of sensitivity.
• Take Gaps Between Treatments: Allow sufficient time between whitening treatments to give your teeth the opportunity to recover.
• Use Desensitising Toothpaste: Incorporate desensitising toothpaste with ingredients like potassium nitrate or fluoride into your oral care routine to soothe nerve endings.
• Limit Hot and Cold Foods: Avoid highly acidic or temperature-sensitive foods to reduce the risk of sensitivity issues.
• Practise Good Oral Hygiene: Follow a consistent oral hygiene regimen, including gentle brushing, daily flossing, and the use of products targeting sensitivity.
• Use Personalised Whitening Trays: Consider custom whitening trays provided by a dentist, ensuring a personalised approach based on your dental history and tooth condition.
