Most Whitening Toothpastes Are Bad For Your Teeth

Everyone wants whiter teeth, and there are numerous whitening toothpaste options on the market. But what exactly makes a toothpaste "whitening," and what sets them apart from each other? In this article, we'll delve into the world of teeth whitening toothpaste to uncover the truth behind their effectiveness and potential risks.

Teeth Color: What's Normal?

To start, we need to understand what “normal” teeth should look like. Your teeth consist of nerves, enamel and dentine. The majority of your teeth are made of dentine, which has a natural yellow-ish color to it. Enamel is the top layer of your teeth, and it’s translucent. This means dentine can shine through, which is why teeth can appear yellow and vary from person to person. So, that yellow tint on your teeth is perfectly healthy and normal! 

If you start to notice your teeth becoming more yellow, this can be due to several factors, including: 

  • The natural aging process

  • Overzealous brushing

  • An acidic diet

  • Smoking

  • Other staining behaviors

Types of Whitening Toothpaste

Whitening toothpaste employs different mechanisms to enhance the whiteness of teeth. Let's explore some of the key types:

Peroxide-Based Whitening Toothpaste:

  • Chemical Whitening Ingredient: Peroxide-based whitening toothpaste contains hydrogen peroxide or carbamide peroxide as its primary active ingredient. These chemicals work by breaking down stains on the surface of your teeth and can penetrate the enamel to lighten deeper stains.

  • Effectiveness: Peroxide-based toothpaste is generally the most effective at whitening teeth. However, the concentration of peroxide in over-the-counter toothpaste is limited by regulations, so the results may be less dramatic than professional treatments.

  • Safety: When used as directed, peroxide-based toothpaste is safe for most people. However, it's essential to follow the instructions carefully to prevent overuse, which can lead to tooth sensitivity and gum irritation.

Enzyme-Based Whitening Toothpaste:

  • Natural Whitening Ingredient: Enzyme-based whitening toothpaste uses natural enzymes, such as papain or bromelain, derived from papayas or pineapples. These enzymes break down and remove surface stains on your teeth.

  • Effectiveness: While enzyme-based toothpaste may not provide as immediate or dramatic results as peroxide-based options, it offers a safe and gentle way to whiten your teeth naturally. It's particularly suitable for people with sensitive teeth.

  • Safety: Enzyme-based toothpaste is generally considered safe and risk-free. It doesn't contain harsh chemicals that can irritate your gums or cause tooth sensitivity.

Abrasive Whitening Toothpaste:

  • Physical Whitening Ingredients: Many toothpaste brands use abrasives like silica, baking soda, or activated charcoal as their primary whitening agents. These abrasive particles help mechanically scrub away surface stains from your teeth.

  • Effectiveness: Abrasive toothpaste can provide visible results by quickly removing surface stains. However, it's important to note that long-term use may lead to enamel erosion, which can make teeth appear more yellow over time.

  • Safety: While abrasive toothpaste can be effective for short-term whitening, it's not recommended for long-term use, as it can potentially damage your enamel and lead to tooth sensitivity.

How to Keep Your Teeth White: Best Practices

Besides using the right toothpaste, here are some additional tips to maintain your teeth's brightness:

Avoid Staining Substances

Maintaining a radiant smile requires vigilance, especially when it comes to avoiding substances that can leave unsightly stains on your teeth. Some of the usual suspects include coffee, beloved for its morning wake-up call but notorious for its staining potential. Red wine, with its rich hues, can also leave lasting marks on your enamel. 

Turmeric, while celebrated for its health benefits, can be a teeth-staining culprit if consumed frequently. Dark berries like blueberries and blackberries are packed with antioxidants but can also impart unwanted discoloration over time. And let's not forget about tobacco products; smoking and chewing tobacco are notorious for yellowing teeth and pose serious oral health risks. By being mindful of these staining agents and moderating their consumption, you can take steps to preserve your pearly whites.

Pay Attention to Your Brushing Technique

When it comes to maintaining a healthy and dazzling smile, your brushing technique plays a crucial role. The first rule of thumb is to choose a soft-bristle toothbrush when using whitening toothpastes. Using gentle, circular motions rather than vigorous scrubbing is key. Brushing too hard can lead to enamel erosion and gum recession, so it's important to strike the right balance between thorough cleaning and gentleness.

Don't rush your brushing routine; spend at least two minutes cleaning all surfaces of your teeth, including the front, back, and chewing surfaces. Pay extra attention to hard-to-reach areas, such as the back molars, and don't forget to brush your tongue to remove bacteria that can cause bad breath.

Limit Acidic Foods

Acidic foods are bad for your teeth primarily because they can erode the protective enamel, which is the outer layer of your teeth. Enamel is the hardest substance in the human body and serves as a shield against tooth decay and sensitivity. When you consume acidic foods or beverages, several negative effects on your teeth occur such as:

  • Enamel erosion

  • Tooth sensitivity

  • Increased risk of cavities

  • Tooth discoloration

To protect your teeth from the negative effects of acidic foods, you should avoid eating high amounts of:

  • Citrus fruits

  • Tomatoes 

  • Pickles

  • Soda 

  • Sugary foods

  • Vinegar

Post-Meal Wait Time 

When you eat, especially if your meal includes acidic foods or drinks, the pH level in your mouth becomes more acidic. This increased acidity temporarily softens the enamel, the protective outer layer of your teeth. Brushing your teeth immediately after eating when the enamel is in this softened state can potentially lead to enamel erosion or damage.

Waiting for about 30 minutes allows your saliva to naturally neutralize acids, and the pH level in your mouth to return to a more balanced, less acidic state. This minimizes the risk of damaging your enamel while brushing.

However, you don't need to wait to perform other oral hygiene practices. You can still rinse your mouth with water after eating to help remove food particles and acids. Additionally, it's a good idea to floss to remove any food stuck between your teeth.

The Bottom Line

In the quest for whiter teeth, it's crucial to choose the right approach. While consulting with your dentist for professional tooth whitening provides the quickest results, using toothpaste with natural enzyme-based whitening ingredients offers a healthier and more sustainable solution. Protecting your enamel and adopting good oral hygiene practices can go a long way in maintaining your bright smile naturally.
