Misconception 1: Pharmaceutical Whitening Has No Side Effects
Many perceive teeth whitening as an inexpensive and remarkably simple procedure, often purchasing whitening products from pharmacies, supermarkets, or online for self-application. These products include whitening toothpaste, whitening strips, and bleaching varnishes. However, without professional guidance, results may be suboptimal, and there is 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 2: Teeth Whitening is Suitable for Everyone
While relatively safe, teeth whitening isn't suitable 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 teeth are still developing, and pregnant women are also advised against the procedure.
Misconception 3: Everyone Can Achieve Perfectly White Teeth
Teeth whitening essentially enhances the natural whiteness of teeth with a good baseline, serving as a cosmetic enhancement. If your teeth are deeply discolored, medical procedures can restore a snow-white, crystal-clear appearance.
Misconception 4:Eat whatever you want after treatment
For 48 hours following teeth whitening, avoid extremely cold or hot foods and beverages like coffee, tea, or cola that can stain teeth. To prevent further pigment absorption, refrain from consuming easily staining foods such as mulberries or spicy hotpot for one week. Chewing betel nuts and smoking should also be avoided.
