Cold-light Whitening for Stained & Discolored Teeth

Published on:2019-7-18

Discolored and stained teeth is one of the biggest concern for most people. However, there are different types of stained teeth, therefore patients need to be aware of the reasons why teeth are yellow, stained or discolored. Therefore it's advised that patients should visit a dentist to get professional advice.


Types of Stained Teeth


  • Exogenous stains are formed due to bad oral hygiene leading to buildup of calculus and plaque. Those who smoke, drink alcohol and consume dark colored foods and beverages cause stains. If stained teeth are down to these factors then whitening treatment is likely to be more successful as the pigmentations are external and on the surface of the teeth.

  • Endogenous stains are formed during the development of the tooth. This can be a result of Fluorosis which is considered an endogenous stain because the fluoride mineral affected the teeth while they were forming. Tetracycline stains due to intake of Tetracycline antibiotics can cause very dark stains. These stains and discoloration are rather difficult to improve through whitening treatment.   


Teeth Whitening Results


Before the cold-light whitening treatment is carried out a shade guide will be used so after the procedure the results can be shown. In most cases, cold-light whitening results are often very successful with teeth being 5 to 6 shades lighter, the majority of patients can expect at least a 3 to 4 shade difference.   


Tips: How white will your teeth be after a whitening treatment will depend on your needs. There are patients who prefer the natural look and others who want a Hollywood white smile therefore results will differ for everyone. We advise that you choose a professional dentist for a consultation and listen to their recommendations.
