Frequently Asked Questions
Causes of teeth staining
There are a number of factors that can result in staining or discoloration of the teeth. Broadly, these factors are divided into extrinsic and intrinsic factors.
Extrinsic factors include food and beverages that can cause staining such as coffee, tea, wine, sauces, fruit such as berries and other food that contains artificial coloring agents. Habits such as excessive smoking can also leave stains on teeth that cannot be cleaned by brushing alone.
Intrinsic staining can be caused by dental conditions such as fluorosis which can leave white, yellow and brown discoloration on teeth, by drugs such as tetracycline, by dental restorative materials, direct trauma to a tooth or multiple teeth, root canal procedures and ageing. Failure to maintain ideal oral hygiene on daily basis can also cause generalized discoloration of the teeth.
How long does the effect last and how to maintain it?
All teeth whitening procedures performed at the dental clinic have lasting effects, however, the consumption of staining beverages, teeth and excessive smoking can discolor the teeth once again. Failure to maintain good oral hygiene can also affect the results shortly after the procedure has been done.
It is for this reason that all leading dentists instruct patients on how to clean teeth properly, and to keep the consumption of food and beverages that can cause staining to the minimal. The effects can be prolonged by proper cleaning, giving up smoking, and reducing consumption of foods and drinks that can cause teeth discoloration.
