In recent years, different types of teeth whitening have increased in popularity. Although teeth are typically mostly white, did you know that tooth enamel color can come in many different shades? Especially over time – your enamel can become discolored or stained. Tooth discoloration can occur for multiple reasons out of your control including injury or illness.

Research was conducted asking individuals what they would like to improve most about their smiles. The most common answer in this study was that people wanted whiter teeth (American Academy of Cosmetic Dentistry).

According the American Academy of Cosmetic Dentistry, nearly 90% of patients asked about teeth whitening treatments. So you’re not alone if you have been thinking about whitening your teeth lately.

Discolored Teeth Cause

Foods that may cause your teeth to become discolored

As you get older – you may see your teeth change in color. This can be caused by multiple reasons:


Soda, tea, coffee, and red wine are notorious for causing tooth stains. The color pigment in these drinks are so intense that they have their own name, they’re called chromogens. These chromogens attach to the white on your enamel (the outer part of your tooth) which causes stains or discoloration.

Tobacco Use

There are a couple of chemicals in tobacco that lead to tough teeth stains. Nicotine and tar are the biggest culprits of causing teeth stains. Tar contributes to staining because it is naturally dark, meanwhile, nicotine has no color until it is mixed with oxygen. When oxygen and nicotine mix, it transitions into a yellowish substance causing teeth stains.


Underneath your tooth enamel is an even softer layer of the tooth called dentin. Which, in nature, is more yellow. As we get older, our tooth enamel thins out which leads to more of the yellowish dentin to show through.


Being hit in the mouth or other types of mouth injuries may cause your tooth color change. This happens due to your teeth not receiving adequate blood flow any longer. The tooth may end up healing itself over time… or it may just die altogether. It’s best to have a dentist examine your mouth injury so they can recommend treatment for the future.


Some high blood pressure medications, antihistamines, and antipsychotics may have side effects that cause your teeth to darken. Younger children who were exposed to antibiotics such as doxycycline and tetracycline while in the womb or while their teeth are forming may have discolored teeth when they hit adulthood. Neck radiation and chemotherapy may also cause teeth to darken.

How Does Teeth Whitening Work?

Teeth whitening is actually simpler than you might think. It all depends on the product you chose and if you decide to whiten your teeth professionally by your dentist or at home.

Whitening products utilize one of the following tooth bleaching ingredients: carbamide peroxide or hydrogen peroxide. These chemicals help break tooth stains into smaller pieces and reduce the color concentration which helps make your teeth look brighter.

Does Teeth Whitening Work on All Teeth?

Sadly, whitening doesn’t work all of your teeth. Thus, it is very important to talk with your dentist to identify the right option for your teeth. Some teeth whitening systems do not correct all types of discoloration and staining. Typically yellow teeth bleach better than brown teeth. Brown and gray teeth might not respond to the chemicals as well as yellow teeth do.

It’s also important to note that whitening doesn’t work on caps, crowns, veneers, fillings, or other dental appliances. If your teeth are discolored due to trauma or medication, bleaching your teeth may not be effective.

Options for Teeth Whitening

There are multiple options for teeth whitening at home and professionally. Make sure you speak with your Dentist prior to starting any whitening treatments. Many teeth whitening treatments range from gentle surface whiteners  — to stronger whiteners that help remove deep stains.

Whitening Toothpaste

Toothpaste that has whitening ingredients help remove stains on the surface of teeth. These pastes are considered gentle and are a great option for individuals with sensitive teeth. Whitening toothpaste doesn’t typically have adverse side effects like bleaching chemicals because they use a polishing action. Since they are so gentle, they do not noticeably whiten teeth as much a chemical products. If you use whitening toothpaste, it is important to note that you need to use it repeatedly to show visible results. Usually, it takes weeks to months.

At-Home Teeth Whitening Treatments

Teeth whitening kits that you can take home can be purchased from your dentist or over the counter. There are so many different types of kits including: whitening strips, lights, trays, brushes, and rinses. Typically these products contain peroxide which helps work underneath the surface to lighten your tooth enamel. These kinds of treatments are usually used regularly over a few days or weeks.

When you consult with your dentist, they may make a special whitening tray for you to help fit your upper and lower teeth better. This option can be better than the one-size-fits-all trays that you purchase at the drug store. If you use a custom stray – you’ll start by squeezing the whitening gel into the tray and wear it for a short time during the day or overnight (this depends on your dentist’s advice). Be careful wearing the trays for too long because the peroxide in the gel can irritate your gums and/or teeth. Make sure you follow your dentist’s instructions!

Professional Teeth Whitening

Getting your teeth professionally whitened is done inside a dentist’s office. These types of whitening treatments are much stronger than the other two alternatives above because the solution contains more peroxide. This option can change your tooth color faster than at-home methods.

Professional whitening typically only takes about an hour. Your gum tissues are covered with a protective gel or a thin sheet of rubber to help protect your mouth from the peroxide. In conjunction with the peroxide, occasionally a laser or light will be used.

The Difference Between At-Home Teeth Whitening and Professional Teeth Whitening

There are many differences between professional teeth whitening and at-home whitening. It all depends personally on the type of results you want to achieve as well as your overall oral health.


The time it takes to whiten your teeth at the dentist’s office versus whitening them at home is significantly different. Professional teeth whitening takes about 1-2 hours at the office but will lift the shade of your teeth up to 8 times whiter. On the other hand, at home treatments require you to whiten about 1-2 hours per day for multiple days or weeks for your teeth to turn 3-6 shades whiter.


On average, at-home whitening kits cost about $50, whereas professional teeth whitening are about $300* or more. In terms of professional teeth whitening, many people find that it’s more beneficial because the whitening occurs faster and is completed in one sitting. Versus at-home whitening kits, people may experience inconsistent results depending on your oral health and your teeth.


Professional whitening can penetrate deep below the surface of the tooth which in turn will help your teeth stay whiter, longer compared to at-home treatments.
