Teeth Whitening


Over time, our pearly white teeth start to discolour. A host of factors can contribute to discolouring including the food and drink we consume, smoking, and age.

The majority of stains are the result of smoking or consuming foods that contain strong colourants such as red wine, coffee, and tomato-based foods.

STAINS THAT ARE RESISTANT TO CHAIRSIDE WHITENING

  • Teeth that exhibit inorganic stains

    do not typically respond well to chairside whitening. In some cases, stains of this nature may look darker if the surrounding teeth are whitened.

  • Teeth that have been exposed

    to trauma, which darkens the dentin

  • Teeth that have been strained

    due to tetracycline antibiotic ingestion during tooth formation. These drugs chemically bind with the crystalline structure of the enamel of the tooth and the underlying dentin

  • Teeth that have been overexposed

    to fluoride, which can lead to fluorosis and, subsequently, tooth discoloration

Discoloration of this nature is limited to the upper enamel layer of the tooth’s surface.

Other stains can be the result of hereditary factors or caused by taking certain medications. These tend to be located deeper in the tooth, in the dentin layer.

Teeth can be whitened through the use of a hydrogen peroxide or carbamide peroxide that develops into a hydrogen peroxide. A variety of different whitening formulations are available that range from 10% carbamide peroxide (equal to 3.4% hydrogen peroxide) to 38% hydrogen peroxide.

During the whitening process, the oxidizing agent enters the enamel and dentin and chemically reacts with the discoloured particles that sit within the structure of the tooth. This causes the molecules to reflect less light and the tooth subsequently appears to be lighter.

One common concern that patients express is that teeth whitening will cause damage to the tooth. At Revive Clinics we use a secure whitening system, which has been proven to maximize whitening while also ensuring optimal patient comfort and safety. Our technology incorporates the most advanced light filtration system available to create powerful results at a lower temperature than alternative systems, thereby reducing the risk the patient will develop post-treatment tooth sensitivity.

Revive Clinics uses a powerful 150-Watt halogen bulb that emits a high-intensity blue light (480-520 nanometers wavelength) to efficiently whiten stained teeth that have been discoloured by food and beverages, smoking, or even medication.

Before you start any teeth whitening treatment, our dentist will help you to develop a teeth whitening plan that is aligned with your needs and the level of discoloration of your teeth. The treatment times will vary according to your desired whitening results; however, sessions typically take around 45 minutes in total.

STAINS THAT ARE EFFECTIVELY REMOVED WITH CHAIRSIDE WHITENING

Chairside whitening can effectively remove the organic stains or discolorations that are caused by the following:

  • Aging. As you age, your teeth will typically darken and take on a green, brown, grey, or yellow shade. Yellowed teeth tend to be the easiest to whiten.
  • Consumption of certain foods; for example, tomato-based foods, coffee, red wine, and fruits.

Smoking.


ARE YOU SUITABLE FOR CHAIRSIDE WHITENING?

Chairside whitening will not be suitable for you if you suffer from any of the following conditions:

  • Gum and teeth hypersensitivity. In such cases, your dentist will advise you to use take-home bleaching trays that contain a lower concentration of carbamide peroxide, which is not as powerful as hydrogen peroxide.
  • Deep staining. Some stains may be resistant to high-concentration chairside bleaches. In cases such as this, your dentist may advise you to undergo a supervised regimen of concentrated at-home bleaching or to consider alternative solutions such as crowns, veneers, or bonding.
  • Teeth that have a transparent aesthetic. Some teeth, particularly the front teeth, tend to become translucent with age. This cannot be treated via whitening processes.
