What is Tooth Whitening? Let us explain

Ray Dup - Friday, June 03, 2016

Teeth whitening removes the discoloration and stains and will lighten up the teeth. This is one of the most popular dental procedures because it restores the natural tooth shade. This restoration can be done using certain procedures to remove the stains caused by tobacco, red wine, tea, coffee etc. Visiting a dentist once in a while would be a very wise decision as the doctor will clean your teeth commonly termed as ‘Scale and polish’. By various oral hygiene methods, this can be done even at home. Without a professional clean, calculus will be difficult to remove.

 

Bleaching is very much required to restore the natural shade which is a procedure commonly used in cosmetic dentistry. Many different techniques are also used to carry out this action and can vary depending on the dental professionals. Various products are now available in the market for home use. Bleaching pen, bleaching strip, bleaching gel and laser tooth whitening are the different techniques used to whiten the teeth.

Bleaching methods include hydrogen peroxide and carbamide peroxide and people claims that hydrogen peroxide is more effective than carbamide peroxide. But hydrogen peroxide has certain side effects like irritation of the gums and high sensitivity of the teeth.

 

Causes of tooth staining:

 

 Due to the build up of surface stains, teeth will get darkened and hides the natural color.

 

Extrinsic:

 

  • Calculus - A hard deposit will be formed around the gumline due to the neglected plaque and appears in different colours like yellow, brown, black or grey.
  •  
  • Dental plaque - This is actually not visible on the teeth surface but the plaque can become stained by chromogenic bacteria like Actinomyces.
  •  
  • Betel chewing.
  •  
  •  
  • Foods and drinks rich in xanthones and carotenoids will result in teeth staining. Discoloring is also caused by colored liquids like tea, coffee, red wine and all sports drinks.
  •  
  • Environmental exposure or medication can lead to the exposure to many metallic compounds including iodine, iron, copper, cadmium and nickel.
  •  

Intrinsic:

 

  • Hyperemia
  •  
  • Tooth decay
  •  
  • Enamel hypoplasia
  •  
  • Fluorosis
  •  
  • Porphyria
  •  
  • Age - As time goes by, the tooth enamel will become thinner.
  •  
  • As a result of internal resorption or pulp necrosis, dental trauma can cause the darkening of teeth.
  •  
  • Minocycline and tetracycline- Minocycline is a derivative of tetracycline which is a broad spectrum antibiotic. This can help in the treatment of acne. The color of the teeth changes when the drug is injected and a yellow-green discoloration will be visible through the enamel and appears to be fluorescent under ultraviolet light.
  •  

Whitening options:

  
 

  • Here, I am going to mention two different ways to put the shine back in your smile.
  •  
  • In-Office bleaching - This type requires just one visit and is also known as chairside bleaching. Bleach is applied to your teeth after adding a protective gel to protect your gums.
  •  
  • Whitening toothpaste - Check for the ADA seal before buying and this denotes a safe whitening toothpaste. They cannot change the color but will remove all the stains present in the teeth.
  •  
  • These different techniques can be used once in a while to keep your teeth clean and whitened.
