Common Causes of Discolored Teeth

Over time teeth might get discolored due to several reasons. Some common cause behind discolored teeth are:

Food and Drink

Among food and drinks, coffee, tea, and red wine are known for leaving stains and the pigments present in them can lead to discolored teeth.


Tobacco contains tar and nicotine, the two chemicals that can leave tough stains on your teeth.


There’s a softer layer called dentin that is below the tooth enamel. With age, the enamel gets thinner causing the yellowish dentin to show.


If you have had some injuries in your mouth, your teeth might not be getting enough blood anymore causing your teeth to appear discolored.


Medicines like antihistamines, antipsychotics, and medications for high blood pressure can contribute to teeth darkening.

How does Teeth Whitening Work

Teeth whitening process is fairly simple and straightforward. But it will vary with what product you choose and whether you want to get it done professionally or at home.

Teeth whitening products contain bleaches, often hydrogen peroxide or carbamide peroxide, which breaks down the stains into smaller pieces and reduce the color concentration of the stains. Thus, making your teeth whiter.

Options for Teeth Whitening

As mentioned, there are several options for teeth whitening and you should consult your doctor before choosing one. The common options for whitening your teeth are:

Whitening Toothpaste

Toothpaste meant for whitening is gentle whiteners, which are great for sensitive teeth. They work on the surface and remove light stains quite effectively. Because they use a polishing action and no bleaches are present, whitening toothpaste is safe to use with no adverse side effects. 

However, they are gentle whiteners and will not work in whitening more severe stains. 

At-Home Teeth Whitening

At-home teeth whitening kits can be of different types like whitening strips, trays, rinses, brushes, etc. and they can be bought over the counter. These products usually contain peroxide which works in lightening the tooth enamel. But you’ll have to use them for some days or even weeks to notice a difference. 

Professional Teeth Whitening

Professional teeth whitening will be done by a certified dentist. They too will use a whitener, but they will be stronger as they contain more peroxide. They are faster in producing results than at-home whiteners and will whiten your teeth within an hour. 

These are the options that you have for teeth whitening. While at-home whitening will cost you less, professional whitening can be extremely fast in producing the desired results.
