All you need to know about teeth whitening

Teeth whitening is one of the most widely sought-after cosmetic procedures aimed at enhancing the beauty of one's smile. It is a simple procedure that uses a highly effective whitening gel to remove the stains from the teeth surfaces, thereby giving you a brighter smile. This brief read will help you understand how teeth whitening is performed and the various options you can choose from.

What are the common causes of teeth discoloration?

  • Tobacco: Chewing tobacco and smoking cigarettes are the leading causes of teeth staining. The tar and particulate matter from the smoke can enter the porous surface of the teeth and get dislodged in it, making them look discolored and dull.
  • Improper oral hygiene: Not brushing or flossing the teeth regularly can lead to excess microbial deposition on them, making them appear duller. It can also lead to the formation of dark tartar patches on them.
  • Excessive consumption of colored foods: Eating a lot of colored foods can make the teeth appear discolored, as the coloring particles from the food can get accumulated in their porous structure.

What is the science behind teeth whitening?

Most teeth whitening gels contain one major ingredient - Hydrogen peroxide. It is a bleaching agent that produces oxygen molecules when applied to the teeth and activated. These molecules gently penetrate the porous structure of the teeth and bleach the staining or coloring particles, thereby giving you a more pleasing and whiter smile. The gel doesn't cause any physical changes to the structure, contour, or surface of the teeth, thereby making the procedure non-invasive and convenient for the patient.

What are the various methods of teeth whitening?

  • Conventional in-office whitening:This procedure is the simplest and most commonly performed type of whitening. It is carried out at a dental practice by a professional dentist and may require a couple of hours to be completed. The procedure can be repeated multiple times if the severity of staining doesn't reduce with just one application.
  • Take-home whitening trays: Teeth whitening kits are provided by dentists after taking precise digital impressions of the teeth and using them to fabricate customized-whitening trays. These trays are made from dental-grade plastic, and the dentist will also suggest a suitable whitening gel to be used in combination with it.

Laser teeth whitening:Using an activating laser to speed up the whitening procedure is one of the most advanced teeth whitening methods. It is highly effective, quick, and its effects last for a longer time.
