Let’s be honest. Whiter, brighter, more confident smiles are all that and more desirable! For today’s generation, teeth whitening strips are accessible and easily available to use for quick results in the comfort of home. But have you ever questioned whether at-home options like this could do more harm than good? Let’s get into the science to see if teeth whitening strips are bad for your teeth. And what should you be doing instead to obtain that perfect smile. A dentist in Rozelle explains more below.
How Do Whitening Strips Work?
First, let’s examine how they work in the first place. Teeth whitening strips are thin plastic strips coated with a whitening gel on top. This gel features a bleaching agent—hydrogen peroxide or carbamide peroxide are the most common. When applied to the teeth, it adheres to the enamel. The peroxide penetrates the enamel and assists in reducing discolouration over time.
But, in order to fully appreciate such an at-home whitening convenience, it’s important to know the disadvantages of whitening strips.
- Whitening Strips Cause Tooth Sensitivity: Whitening strips can, in fact, make teeth more sensitive. Whitening strips have bleaching agents that penetrate into the dentin. The dentin is the layer underneath the enamel that has a lot of protein in it. According to Healthline, increased teeth sensitivity is a common adverse reaction to teeth whitening.
- Whitening Strips Can Irritate Gums: The bleaching agents in whitening strips can irritate your gums, leading to gum pain and sensitivity. According to Perfora, extended exposure to whitening strips can cause negative effects to the gums, even long-term. This includes bleeding gums, swollen gums, and literally burned gums.
- Uneven Colour: Ever worried about a patchy smile? According to an emergency dentist, whitening strips can sometimes lead to uneven colour, where some teeth appear whiter than others. This can happen due to variations in tooth structure or how well the strip adheres to different parts of your teeth.
- Potential Harm to Enamel with Overuse: While teeth whitening strips are generally considered safe for the enamel, it could cause harm if used severely. Regular and excessive use of whitening strips can wear away the enamel, leaving it vulnerable to cavities and other dental problems.
- Allergic Reactions: Though less common, whitening strips can also trigger allergic reactions in some individuals, causing symptoms like itching, swelling, and rashes around the mouth.
- Damage to Dentin: Research by the American Society for Biochemistry and Molecular Biology indicated that whitening products can instigate a significant loss of collagen, which is the predominant protein in dentin. This potential damage to the dentin’s collagen is a concern regarding the long-term health and resilience of your teeth.
The Brighter Alternative: Professional Teeth Whitening
So, what’s the better way to achieve a brighter smile? The benefits and effectiveness of professional teeth whitening by dentists often make it a superior choice. Here’s how.
- Achieving a Better Colour Change: A systematic review and meta-analysis published on PubMed directly compared whitening strips with dentist-supervised at-home bleaching. The study concluded that dentist-supervised bleaching led to a better colour change when measured with a spectrophotometer. While this colour alteration might have been undetectable by the unaided human eye, it indicates a more significant whitening effect with professional guidance.
- Lower Risk of Tooth Sensitivity: As Healthline points out, dentists may provide fluoride treatments after in-office whitening to help rebuild the tooth’s internal structure and minimise and prevent increased sensitivity. Fluoride-containing toothpastes are also recommended when whitening at home. This proactive approach to managing sensitivity is a significant advantage of professional treatment.
- Controlled Application for Optimal Results: Dentists use professional-grade whitening products that provide better results. A dental Rozelle expert applies the agents under carefully controlled conditions to protect your gums and achieve even application.
- Personalised Assessment and Treatment Plans: Before any professional whitening procedure, your dentist will conduct a thorough examination of your teeth and gums. This allows them to assess the cause of your tooth discolouration and determine the most effective and safest whitening approach for your specific needs. They can also consider any pre-existing dental conditions that might influence the treatment. Get started by searching “dental clinic near me” online.
- Enhanced Protection for Your Enamel and Gums: Dentists take precautions to protect your enamel and gums during the whitening process. They may use barriers or protective gels to shield your gums from the bleaching agent, minimising the risk of irritation and burns.
Choose Wisely for a Healthy, Radiant Smile
While whitening strips offer a convenient and often more affordable initial solution for a brighter smile, it’s crucial to be aware of their potential downsides. For a more effective, safer, and personalised approach to teeth whitening, consulting your dentist is always the best course of action. Ultimately, a healthy and radiant smile is an investment, and choosing the right path with professional guidance is better in the long run.
