7 Important Factors About Teeth Whitening

How Teeth Whitening Gets the Job Done

Whitening of the teeth is a field of science that is tried and tested. Each of the processes has specific guidelines, depending on the product. One of the most efficient procedures is the custom tray teeth whitening, which prevents the oxygen from getting out and lengthens the time of exposure. These products for teeth whitening give off a chemical substance into the tooth enamel, which triggers a reaction.


During diffusion and oxygenation, the chemical bleaches the teeth. It begins on the tooth surface and seeps further into the tissue. The longer the teeth discoloration occurs, the deeper the whitening product has to diffuse into the tissue.


The Number of Gel Syringes Needed

The total number of teeth whitening gel used can vary for every patient. It is easier to determine if the dentist sees the actual teeth. But, the fundamental principles include:


  • Three gel syringes for slightly discolored teeth
  • Six gel syringes for moderately discolored teeth
  • Nine gel syringes for highly discolored teeth


Note: 1 syringe of gel is equivalent to 3 full applications


The Time Frame of the Whitening

It varies based on the amount and frequency of stain causing food that you consume. The standard whitening application for maintenance is 1-2 procedures for every 3 to 6 months.


The Shelf Life of the Gel

If refrigerated, the gel is usable for up to 2 years. If un-refrigerated, it has a shelf life of 1 year.


Can the Whitening Process Damage the Gums

To some extent, our gums become sore from the effects of teeth whitening. This inflammation of the gum is known as a chemical burn, which is similar to the feeling of having a sunburn. In a chemical burn, the affected area gets a bit painful. Gradually, it flakes off after turning white. The gum tissue is expected to return to its normal state in 24 hours.


Will the Bleaching Gel Cause Damage to the Tooth Enamel

The answer is no. For the whitening to be effective, it passes through the tooth tubules and starts to whiten the stained tissue beneath.


The Importance of Desensitizing Gel

The desensitizing gel is usually used to help reduce the sensitivity and prevent the staining rate from increasing. A professional whitening procedure can dehydrate the teeth to some extent for about 48 hours, or until the tubules have restored the depleted mineral content by the organic substance present in the saliva.


The teeth absorb any food or beverage color that is ingested until the teeth are totally rehydrated. The desensitizing gel application helps in the replacement of the necessary nutritional requirements. This gel also closes the pores in the teeth temporarily, minimizes sensitivity, and decreases the re-staining rate.
