Teeth whitening is a popular way to remove surface stains and fix discolored teeth, resulting in a whiter, brighter smile.
Why is it so popular? Well, there’s a reason why 89% of orthodontists have received teeth whitening requests.
Whiter teeth can improve appearance, help with confidence and may even prompt more social opportunities. 99.7% of people believe that an attractive smile is an important social aspect.
Teeth whitening treatments can range from whitening toothpastes and rinses, to at home kits, to dentist-administered procedures, with whitening effects varying with each method.
Toothpastes and rinses will have less of an effect on teeth because they contain no bleaching agents while whitening kits and in-office treatments will be more effective because of higher levels of whitening agents, such as hydrogen peroxide.
There are also a variety of methods to achieve whiter teeth including whitening strips, whitening trays, gel, charcoal scrubs DIY remedies and more.
What treatment you decide on and where you decide to do it (whether at home or in-office) will all depend on the needs of your teeth and what your overall goal is.
It can be beneficial to talk with your dentist about what options are best for you based on your dental history. People with sensitive teeth, teeth with previous dental restoration or cavity-filled teeth will need to take the proper precautions for a safe and successful teeth whitening experience.
How Does Teeth Whitening Work?
We know that teeth whitening treatments are a great solution to stained, discolored teeth… but how do they work?
Knowing the ins and outs of teeth whitening and what makes a whitening solution work can lead to more informed purchases for you and your teeth!
For starters, and to really understand how teeth whitening solutions work, it’s important to recognize the difference between the two major kinds of tooth stains and how they can be removed.
There are two kinds of tooth stains:
Extrinsic stains are those that appear on the surface, or the enamel layer, of the teeth
Extrinsic stains can be whitened simply by using special toothpastes or rinses.
Whitening toothpastes will usually contain:
- A mild abrasive to remove plaque and other bacteria.
- Polishing agents to whiten teeth. Some may even contain hydrogen peroxide (Although unlike whitening kits or in-office whitening treatments, the hydrogen peroxide is inactive and used as minute dosage - there is no bleach in whitening toothpastes).
Whitening toothpastes can whiten teeth to about a maximum of one shade lighter.
Intrinsic stains are those that have seeped through the tiny cracks and and chips in the tooth, down to the dentin layer.
While extrinsic stains can usually be fixed with whitening toothpastes or gels, intrinsic stains need a little more work. That’s where teeth whitening comes in.
Most teeth whitening solutions contain a whitening agent (like hydrogen peroxide) that can penetrate beneath the outermost layer of the tooth - the enamel.
Once past the enamel, the whitening agents come into contact with the tiny, discolored molecules within the pores of your teeth. These molecules then counteract with the oxygen molecules in the whitening solution, breaking them apart.
Oxygen molecules begin to cover the entire surface of the tooth, leaving you a new set of pearly whites.
What Method Are You Using?
Of course, the level of whiteness that results will depend entirely on what whitening system is used. Each whitening system works differently, contains different levels of whitening agents and will yield different results.
For example, at home whitening kits or whitening strips will usually contain only 3% hydrogen peroxide while in-office treatments can contain anywhere from 15 to 43%.
You can expect to see a shade up to 8 times whiter than what you started with when you complete an in-office whitening treatment.
In addition, the current state of your teeth will also affect how whitening treatments work. Those will heavy stains from smoking, coffee, tea or other wear and tear will likely have to put more effort into getting whiter teeth and may opt for a in-office procedure.
Why Do You Need Teeth Whitening?
Teeth whitening is one of the most highly requested dental restorations available. It is a process that doesn’t even require a dentist or special equipment - many teeth whitening kits can be done at home by yourself.
But why bother with a teeth whitening treatment in the first place?

Is Teeth Whitening Safe?
Teeth whitening is the process of using certain chemical agents to bring teeth back to their most natural, whitest shade. Teeth whitening treatments can also aid in the removal of surfaces stains and can help even out the overall color of the teeth.
It is a process that appears foolproof… But is it safe?
Generally speaking, teeth whitening is completely safe so long as it is done correctly. As is true with most medicines you take or procedures you go through, it’s important to follow the directions exactly as they are given.
When executed properly, you may experience some minor teeth sensitivity but nothing that should compromise your overall health or wellbeing.
However, teeth whitening can become unsafe for a few different reasons. In this article we will be going over those reasons and how you can ensure you have a successful and, more importantly, safe teeth whitening experience.
How White is White?
The goal of teeth whitening shouldn’t be to have “white” teeth but rather to remove surface stains, balance color and improve the overall appearance of your teeth.
When starting a teeth whitening treatment, it’s impossible not to imagine yourself with a set of sparkly white new chops. We are often triggered by words like, “luxe,” “diamond,“ ”3D white” and others that are advertised on teeth whitening treatments. But what do manufacturers really mean when they guarantee ‘white teeth’?
Firstly, it’s important to recognize that we all have a starting, natural shade to our teeth. For some people, this shade is white, others off-white and some even yellow.
So what does this mean?
This means that your teeth can only get as white as their natural shade.
Think of it like this: If you have 5 people with varying tooth shades experience the same treatment - they will all end up with a different shade of ‘white’ at the end of it. Yes - even with the same whitening solution, the same dentists expertises, they will have varying results.
The whiteness of your teeth post-treatment will also depend on the stains you have acquired - both the number of stains and how deeply they have penetrated the tooth.
What to Consider Before Teeth Whitening?
Thinking about improving your smile with teeth whitening? You are not alone! The teeth whitening products market is expected to reach USD 7.40 billion by 2024.
There is clearly (and will continue to be) a demand for whiter, brighter smiles. And it’s easy to see why. It’s fast, adorable (and continues to decrease in price as it rises in popularity) and, most importantly, is proven to be safe and effective.
But before you begin any teeth whitening treatment, there are a few essential things you need to consider.
So put those whitening trays down and read in for the Four Things You Should Know Before You Whiten Your Teeth.
#1 Teeth Whitening Isn’t For Everyone
I know, I know… we all want that perfect, white, glowing smile. But, unfortunately, teeth whitening is not an ideal tool for everyone.
How do I know if I shouldn’t whiten my teeth?
The reasons for avoiding teeth whitening vary from health-related issues to previous dental work. Some circumstances that might prevent you from teeth whitening include:
You have gum disease
You have gum disease
The agents in whitening gels can actually cause further harm and sensitivity to your gums. Talk with your dentist about your options prior to performing any teeth whitening treatment.
You still have baby teeth.
Teeth whitening is not recommended for children who still have baby teeth. This is because it can take about 2 years for the enamel layer of protection to grow onto new adult teeth.
You still have baby teeth.
If any of the above apply to you and your dental health, refer to your dentist prior to making any teeth whitening choices.
Speaking of your dentist…
#2 Always Consult with Your Dentist
Even if you think you are an ideal candidate for teeth whitening, it’s advised you still talk with your dentist.
Why? Well, for starters it will only help – not hurt.
And, second, they may be able to recommend certain products or treatments that are better suited for your teeth and dental history.
Most of the time, your dentist should give you the go-ahead! And as I mentioned above, teeth whitening is, generally, safe but…
#3 You May Experience Sensitivity
It is not uncommon to experience discomfort or sensitivity before or after teeth whitening. While it’s usually mild, it’s important to properly prepare for the treatment to avoid any additional pain.
You can reduce (and sometimes eliminate) teeth whitening sensitivity by doing the following:
- Start brushing with a soft-bristled brush
- Use a fluoride heavy or sensitive toothpaste
- Limit acidic foods and beverages post-treatment
- Use lukewarm water for brushing, rinsing or consuming post-treatment
It’s better to be cautious and implement these pre and post treatment tips than risk the surprise of a painful recovery!
#4 Be Realistic
Lastly, it’s important to consider the fact that your dream teeth and your reality teeth may not be the same.
Trust me – I’m not trying to crush your dreams! I’m simply stating the fact that every single person has a different natural teeth shade. Some people have white, some off-white and some may even have a natural yellowish tone.
For this reason, teeth whitening can only get your teeth back to their most natural shade. It’s important that you know going into the procedure that your teeth may not turn out to be as blindingly white as you originally pictured.
But that shouldn’t be your goal anyway! Teeth whitening is meant to get your teeth back to their natural shade, to remove surface stains and to make you more confident!
Now that you know what to consider before teeth whitening… what are you waiting for!
How Often Should You Whiten Your Teeth?
After completing a teeth whitening treatment, it’s not uncommon to immediately ask yourself, “When can I get them whitened again?” After all, we want to keep our teeth as white as possible for as long as possible, right?
But over-whitening can cause discomfort and, in more serious cases, permanent damage to your teeth. The cells in your teeth are sensitive to the peroxide in the whitening agents and can lead to health-related issues such as gingivitis.
The goal of any teeth whitening treatment should be to attain those pearly whites and keep your teeth safe, happy and healthy!
So how often should you whiten your teeth?
Let’s start by considering what kind of whitening treatment you’ll be using. There are essentially two ways you can use a teeth whitening treatment: In-office or at home.
In-office whitening performed by a dentist will usually last for at least one year. This is because the whitening agents are stronger and will have more of an effect on your teeth. You’ll usually only have to come in once, maybe twice, to complete an in-office whitening. In addition, your dentist can further advise you on how long to wait until your next appointment.
At-home treatments tend to take longer to complete because they ingredients aren’t as strong or potent. Manufacturers do not want to risk customers misusing the product and injuring their teeth or gums.
Because of this, the whitening effect doesn’t tend to last as long compared to in-office treatments and you’ll likely have to do a couple weeks of treatments to complete a round of whitening.. It is advised to wait ait at least 6 months after completing your at-home treatment before considering whitening again. (But, again, you can also talk to your dentist, even with over the counter whitening methods!)
As you can see, the method you choose to whiten your teeth plays a large role in how often you should get a whitening treatment.
But there are other factors that can affect how often you should whiten your teeth, including your lifestyle.
People who drink coffee, smoke or fail to maintain proper dental hygiene may require more frequent whitening treatments than others.
You can reduce the amount of whitening treatments you’ll need by trying to do some of the following:
- Drink through a straw - Drinking through a straw can keep your teeth from coming into contact with substances that may stain them.
- Keep up with dental care - Brushing, flossing and using mouthwash regularly can help you maintain white teeth.
- Limit dark-colored drinks - Dark sodas, teas and coffee will stain your teeth the fastest. If you want to keep your teeth whitener for longer, try limiting your intake of these substances.
- Limit acidic drinks and beverages - Highly acidic food and drink can wear away at your enamel, exposing the yellow dentin layer beneath.
How can I tell if I am over-whitening?
If you follow the advice above and abide by the recommended wait time in between treatments, your teeth will generally be able to withstand the chemicals in the whitening agents. However, it is always important to make note of the strength and health of your teeth to ensure you are not over-whitening. There are a few signs that you have over-whitened your teeth, including:
If you notice a change in the sensitivity of your teeth, you may be whitening too often. The whitening agents in the treatments can wear down enamel if used too frequently. When the enamel wears down, the dentin layer beneath is exposed and can lead to discomfort when chewing, biting or when coming into contact with hot or cold temperatures.
Similar to increased too sensitivity, your gums may also be experiencing some discomfort or even pain. The chemicals in whitening treatment, when used too often, can irritate your gums, making them more sensitive and even painful. In some cases this may lead to receding gums, exposing parts of the teeth that can no longer be whitened.
The biggest indicator that you are over-whitening is the color of your teeth. If you notice your teeth turning a bluish color or that they are becoming slightly translucent and see-through, seek dental advice immediately. This is a sign that you have over-whitened your teeth and may have wore down the enamel to a dangerous level. This can lead to permanent damage of your teeth.
As scary as over-whitening can seem, it is easily avoidable. If you take the time to complete the treatments properly, wait a long enough time before starting another treatment and talk with your dentist throughout the process, you will have a successful, and, more importantly, safe teeth whitening experience.
