A smile is incredibly important to a person, so many individuals with less-than-perfect teeth hesitate to smile. Is there a way to whiten teeth? What are the common misconceptions about teeth whitening? What should you be mindful of? Let's explore the common myths surrounding teeth whitening.
Misconception 1: Everyone can achieve sparkling white teeth
Teeth whitening essentially enhances the natural whiteness of teeth with a good foundation, serving as a cosmetic enhancement.If your teeth are deeply discolored, even medical treatments like polishing, sandblasting, or cold light whitening won't achieve the snow-white, crystal-clear appearance of celebrity teeth—especially if you have severe tetracycline staining or fluorosis.Among these three methods, tooth polishing and sandblasting cause significant wear to tooth structure, gum damage, and even pulp injury, while cold light whitening is gentler on teeth.
Misconception 2: You can eat whatever you want after treatment
For 48 hours following teeth whitening treatment, avoid consuming extremely cold or hot foods, as well as staining beverages like coffee, tea, and cola.To prevent teeth from absorbing additional pigments during this period, avoid consuming easily staining foods like mulberries or spicy hot pot for one week. Chewing betel nuts and smoking should also be avoided.
Misconception 3: Pharmaceutical whitening has no side effects
Many perceive teeth whitening as an inexpensive and remarkably simple procedure, often purchasing whitening products like whitening toothpaste, whitening strips, or bleaching gels from pharmacies, supermarkets, or online for self-application. However, without professional guidance, results may be suboptimal, and there's a risk of misuse or overuse.Furthermore, these products often contain bleaching agents like hydrogen peroxide and sodium perborate, which can easily cause adverse reactions such as tooth sensitivity, gum irritation, and external resorption at the tooth neck and root.
Misconception 4: Teeth whitening is suitable for everyone
While relatively safe, teeth whitening isn't appropriate for everyone.If you suffer from severe periodontal disease, medical whitening procedures may cause tooth sensitivity or even bleeding. Therefore, dentists generally recommend completing periodontal treatment before undergoing whitening. Additionally, individuals under 18 years old should avoid whitening as their teeth are still developing, and pregnant women should also refrain from the procedure.
