What is Teeth Whitening?

Teeth whitening is a procedure that restores the natural whiteness of teeth, which can become discolored and dull over time due to various factors. This process can be performed using professional techniques in dental clinics or through whitening products available in stores for at-home use. Each method can yield different results in terms of effectiveness and dental health, making it crucial to determine the most suitable option for each patient.

Why Do Teeth Become Yellow?

Teeth can lose their natural color for two primary reasons:

• External Discoloration: Factors such as coffee, tea, food dyes, and smoking can cause yellowing or darkening on the tooth surface. Techniques aimed at treating surface discoloration may be more effective in this case.
• Internal Discoloration: This occurs due to damage or loss of function in the internal tissues of the tooth. Such discoloration is often associated with childhood diseases, medication use, trauma, infections, cavities, or aging. Professional treatments are usually more effective for internal discoloration.

What Are the Options for Teeth Whitening?

Various methods exist for teeth whitening, and it is essential to consult with a dentist to choose the most appropriate option. The available teeth whitening options include:

• Professional Whitening Techniques:
  • Bleaching: This procedure involves the use of carbamide peroxide or hydrogen peroxide by a dentist and is effective for internal discoloration. It provides fast and effective results.
  • Tray Application: Customized dental trays filled with whitening gel are used at home for specific durations.
• At-Home Whitening Techniques:
  • Whitening Toothpastes: These are designed to clean the tooth surface against external discoloration. However, prolonged use may harm tooth enamel.
  • Whitening Strips: These strips, containing low concentrations of hydrogen peroxide, are applied to the tooth surface for a specified period to achieve whiteness.

What Are the Side Effects of Teeth Whitening?

Teeth whitening procedures can cause some side effects:

• Tooth Sensitivity: Increased sensitivity may occur, especially after the initial treatment sessions, leading to discomfort when consuming hot or cold foods and beverages.
• Gum Sensitivity: Contact between whitening products and the gums can lead to sensitivity and irritation.
• Incompatibility with Other Dental Treatments: The color of prosthetics, implants, or fillings may not match the whitened teeth, potentially requiring aesthetic adjustments.

It is important to remember that the whiteness achieved through teeth whitening is not permanent. To prevent discoloration, regular touch-ups with both at-home and professional whitening treatments may be necessary. Additionally, it is advisable to avoid substances like tea, coffee, and tobacco that can cause discoloration.
