A dazzling smile is one of the most attractive features. Teeth whitening, a cosmetic dental procedure that brightens teeth and boosts confidence, has become very popular. In this post, we’ll explore the world of tooth whitening. We’ll look at its science, methods and safety considerations.

Teeth Whitening: Science behind the Procedure

To fully understand teeth whitening, knowing the science behind discolouration is important. 

  • Diet: Consuming certain foods and beverages such as coffee, red wines, teas, and fruits over time can cause teeth stains.
  • Tobacco: Smoking/chewing tobacco can cause severe discolouration of the teeth.
  • Ageing: Our enamel gradually wears down over time, revealing the yellowish-brown dentin below.
  • Drugs: Certain drugs, such as antibiotics, can darken teeth.
  • DNA: A person’s tooth colour can be influenced genetically, as some people naturally have whiter or more luminous teeth.

In dentistry, teeth whitening (also known as dental whitening) is a method that can reverse or reduce discolouration in the teeth by removing stains. Note that not all discolourations are treated effectively by teeth bleaching. A dentist should be consulted to determine the best method.

Teeth Whitening: Methods and Techniques

Many methods are used to whiten teeth, ranging between over-the-counter products and professional dental treatments.

  • OTC Whitening Products: You can buy toothpaste, strips or gels without a prescription. While they’re generally cheaper, the results may be slower than with professional treatments.
  • Professional At-Office Bleaching: Probably the fastest, most efficient way of teeth whitening. Dentists utilize specialized agents and cutting-edge technology to whiten a set of teeth within a single session. This method suits individuals with significant discolouration.
  • Take-home kits: The dentist can provide a custom-fitted tray and professional-grade whitening gel for use at home. This method offers greater convenience and control compared to OTC.

Safety Considerations

If done with the help of a qualified dental professional, teeth whitening is generally considered safe. It is essential to be informed about possible side effects and safety precautions.

  • Temporary Tooth Sensitivity: Some patients may experience temporary tooth pain or gum irritation after teeth bleaching. This usually subsides in a matter of days.
  • Use Excessively: Excessive consumption of whitening creams and products, especially those containing high concentrations of bleaching agents, can increase sensitivity. Please follow any instructions given by your dentist.
  • Maternity and Breastfeeding: Pregnant women or nursing mothers should avoid teeth whitening as there is no evidence that these procedures are safe during this period.
  • Existing Issues with Dental Care: People who have dental crowns, veneers or fillings might not be able to benefit from teeth whitening. Consulting a doctor is important to determine whether you are eligible.
