Why teeth whitening?

With sparkling teeth we all start. But over the time, factors like age, accidents or lifestyle habits cause the enamel on the surface of the teeth to be worn out and hence allowing the yellow core to be made visible, which gives a dull appearance on the outlook. Stains and debris get accumulated and trouble your confidence with their tampered effects. Now in such situations, to restore a sparkling smile back to the face, Teeth whitening helps.

Type of stains:

There are two types of stains. Extrinsic stains are common ones that appear on the teeth’s surface as a result of the exposure to beverages, tobacco or foods. These superficial stains can be removed by proper brushing. Intrinsic stains are stubborn stains that are formed in the interior of the teeth. Intrinsic stains are those that are formed on the interior of teeth as a result of aging, accident, excessive fluoride ingestion, etc. This warrants a regular dental procedure to correct the discoloration extending from few months to a year. At times, when results don’t turn fruitful, the option of Dental veneers is sported.

What Causes Tooth Staining?

  • Age:Tooth color and the progressing age are directly proportional. Wear and tear naturally causes the teeth to discolor over the period of time and it is inevitable. Starting color: IT is to be noted that we are all born with an inborn teeth color, yellow-brownish or grey-greenish, which then shows up over time.
  • Translucency and thinness:These are generic traits and show profoundly over time. Thicker teeth respond well to whitening process and things get fine. But then, when the case is of thin teeth, especially in the front row, then it becomes difficult for whitening to respond. Thinned teeth are one of the cases where Whitening is not found to work upon effectively.
  • Eating habits:Eating excess acidic foods, drinking too much of red wine, coffee and so on, over a period of time, is bound to leave stains on your teeth. This causes the teeth surface to become more transparent and the yellow color to show through.
  • Smoking habits:Nicotine causes intrinsic stains as it leaves back deep brownish deposits that become hard to correct by.
  • Trauma:Accidentals falls/trauma can produce sizable cracks in teeth, causing the collection of stains and debris.

Risks related to Teeth whitening:

  • Sensitivity: The teeth whitening process can cause a temporary rise in sensitivity to temperature and pressure. High concentrated bleaching agents might be the cause for this. At times, sharp pains in the middle of the front teeth called zingers, come as spontaneous waves. While sensitivity may last for a few days, at times, the case might extend to few months too and become a long time hassle.
  • Gum irritation: Over 50% of people using peroxide whiteners report irritation issues in their gums. This is due to the high concentration of the bleaching agents, and usually takes time to diminish over time with proper attention.
  • Technicolor teeth: In case of bonding, dental crowns or veneers, the issue is they don’t respond to whitening unlike natural teeth. So when the teeth are whitened, the surrounding teeth turn white but they remain discolored, leading to a condition called Technicolor teeth.

The procedures are of different types and it differs from person to person according to the nature of the stains. As we can see, there are few essential risks that are involved with a relatively easy teeth-whitening process too.
