A bright white smile is not only about aesthetics, but also about self-confidence. Today, teeth whitening is one of the most popular procedures in aesthetic dentistry. However, there are still many myths surrounding it. In this article, specialists at Diente Sano Clinic (dentistry in Barcelona) will debunk the most common misconceptions and explain how professional whitening really works.
Myth #1. Teeth whitening damages enamel
Many patients fear that the procedure will harm their teeth. In reality, with professional teeth whitening, the enamel remains intact. The products used contain hydrogen peroxide, which is safe for dental tissues and even has an antiseptic effect, reducing bacteria and the risk of inflammation.
Myth #2. At-home whitening is as effective as professional whitening
Whitening strips, gels, and pharmacy kits provide only a mild effect due to the low concentration of active ingredients. Custom trays made in a clinic are more effective, but they require dentist supervision and long-term use. By contrast, teeth whitening in Barcelona at Dientesano Clinic takes only one visit (around two hours) and delivers noticeable results without health risks.
Fact #3. Teeth should be treated before whitening
This is not a myth but a medical fact. If there are cavities or cracks, the gel can cause pain and pulp inflammation. That’s why a dentist must first examine and, if necessary, treat the teeth before whitening. This ensures that the result is safe and long-lasting.
Myth #4. Whitening causes permanent sensitivity
Sensitivity may occur, but it is temporary and usually disappears within 24–48 hours. The enamel is not damaged. Patients at Dientesano also receive personalized recommendations to minimize discomfort and maintain their results.
Myth #5. Whitening lamps overheat teeth and cause cavities
Modern technology eliminates this risk. We use cold LED lamps and blue-spectrum lasers, which are completely safe for teeth and gums.
Myth #6. A strict “white diet” is required after whitening
There is no need for a strict diet lasting months. For the first 48 hours after the procedure, it’s best to avoid strongly pigmented foods and drinks such as coffee, wine, beets, and soy sauce. Afterwards, you can return to your normal diet.
Myth #7. Whitening can only be done every few years
In fact, with professional methods, the procedure is safe even if repeated more often. On average, results last 3–5 years, but whitening can be repeated annually if necessary.
Myth #8. Whitening is suitable for everyone
There are contraindications: pregnancy, breastfeeding, patients under 16, severe gum disease, or allergies to gel components. In addition, fillings and crowns do not change color, so they may need to be replaced.
Myth #9. Whitening always makes teeth perfectly white
Results depend on the natural shade of enamel, lifestyle, and individual factors. Some patients achieve a brilliant white shade, while others see a few tones of improvement. Either way, the effect is visible, and the smile looks much brighter.
