How to Whiten Teeth: Tips and Tricks for a Brighter Smile


Greetings Asensio! Are you tired of yellow or stained teeth affecting your confidence and smile? Discolored teeth can be caused by a variety of factors, such as genetics, age, diet, and lifestyle habits, such as smoking or excessive coffee or wine consumption. Fortunately, there are numerous ways to whiten teeth and achieve a brighter and more appealing smile. In this article, we will provide you with valuable tips and tricks to whiten your teeth effectively and safely.

Before we dive into the methods, it’s essential to understand the reasons behind teeth discoloration. Teeth have three layers: enamel, dentin, and pulp, and the color is determined by the thickness and quality of these layers. Enamel is the outer white layer; dentin is the yellowish layer beneath the enamel, and pulp contains blood vessels and nerves. When the enamel is eroded due to acid or trauma, the dentin becomes more visible, giving the teeth a yellow or grayish hue. The good news is that most teeth discoloration is superficial and can be reversed or prevented with proper care and treatment.

In the following paragraphs, we will explain the various teeth whitening options, their pros and cons, and the best practices for maintaining a healthy and radiant smile. Whether you prefer natural remedies, over-the-counter products, or professional treatments, we’ve got you covered. Let’s get started!

Tips and Tricks for Whiter Teeth

Natural Remedies

1. Baking Soda

Baking soda, or sodium bicarbonate, is a natural and cost-effective way to whiten teeth. Its alkaline nature neutralizes the acidity in the mouth, which can erode enamel and cause discoloration. To use it, mix a small amount of baking soda with water or toothpaste to form a paste, and brush your teeth gently for 2 minutes. Rinse well and repeat once or twice a week, as excessive use can cause sensitivity and enamel damage.

2. Hydrogen Peroxide

Hydrogen peroxide is a bleaching agent that can effectively whiten teeth when used in moderation. It works by breaking down the surface stains and killing the bacteria that cause bad breath and gum disease. However, high concentrations can damage the soft tissues and irritate the gums, so it’s recommended to use a 3% solution and dilute it with water. You can swish it in your mouth for 1-2 minutes or use it as a mouthwash after brushing, but do not swallow it. It’s also advisable to consult your dentist before using it, especially if you have braces or other dental work.

3. Oil Pulling

Oil pulling is an ancient Ayurvedic practice that involves swishing oil, such as coconut, sesame or olive oil, in the mouth for 15-20 minutes and then spitting it out. It’s believed to improve oral hygiene, detoxify the body, and whiten teeth by removing the toxins and bacteria. Some studies suggest that oil pulling can reduce plaque, gingivitis and bad breath, although more research is needed to confirm its benefits. To try it, simply take a tablespoon of oil, swish it around, and spit it into the trash, not the sink, to avoid clogging the pipes.

4. Fruits and Vegetables

Eating a balanced and healthy diet rich in fruits and vegetables can not only boost your overall health but also enhance your dental health and whiten your teeth. Crunchy fruits and vegetables, such as apples, carrots, celery, and broccoli, act as natural scrubbers that remove the surface stains and stimulate the saliva production, which protects the teeth from decay and acid erosion. Moreover, fruits like strawberries and pineapples contain enzymes and acids that can bleach and brighten the teeth without harming the enamel.

Over-the-Counter Products

5. Whitening Toothpaste

Whitening toothpaste is a popular and convenient way to whiten teeth without spending a lot of money or time. It contains mild abrasives and chemicals, such as hydrogen peroxide or baking soda, that remove the surface stains and brighten the teeth gradually. However, it’s essential to choose a reputable brand and read the label carefully, as some toothpaste can contain harmful ingredients or irritants that can damage the enamel or gums.

6. Whitening Strips

Whitening strips are another affordable and easy-to-use option that can whiten teeth in a matter of weeks. They consist of thin plastic strips coated with a bleaching gel that you apply to your teeth for a certain time, usually 30 minutes, twice a day. The gel contains peroxide that penetrates the enamel and breaks down the discoloration, leaving your teeth whiter and brighter. However, whitening strips can cause sensitivity and gum irritation if not used correctly or left on for too long, so follow the instructions carefully.

7. Whitening Kits

Whitening kits are a more comprehensive and professional way to whiten teeth at home, but they require more time, effort and money. They usually contain a mouth tray, a whitening gel, and an activating light or heat source that accelerates the process. The gel contains a higher concentration of hydrogen peroxide or carbamide peroxide that can bleach the teeth more effectively and quickly. However, using whitening kits without supervision or guidance can cause adverse effects, such as burns, over-bleaching, or tooth sensitivity, so it’s advisable to consult your dentist first.

Professional Treatments

8. In-office Bleaching

In-office bleaching, also known as chairside or power bleaching, is a professional and quick way to whiten teeth safely and effectively. It involves applying a concentrated gel of hydrogen peroxide or carbamide peroxide to the teeth and then activating it with a special light or laser that speeds up the whitening process. The procedure takes about an hour or less and can lighten the teeth by several shades immediately. However, in-office bleaching can be costly, ranging from $500 to $1000, and may cause temporary sensitivity or discomfort.

9. Custom Trays

Custom trays, also called take-home trays or night guards, are another professional and personalized way to whiten teeth in the comfort of your home. They involve taking impressions of your teeth and then creating custom-made trays that fit snugly over them. You fill the trays with a whitening gel and wear them for a specific time, usually overnight, for a few weeks or months, depending on the desired results. Custom trays can provide excellent and long-lasting results without the risks or inconvenient of in-office bleaching, and they cost less, about $200 to $500, depending on the dentist’s fees.

The Do’s and Don’ts of Teeth Whitening

Now that you know the various options for teeth whitening, let’s focus on the do’s and don’ts of teeth whitening, to ensure that you achieve the best results and avoid any harm or disappointment.

The Do’s

1. Do brush and floss regularly

Prevention is better than cure when it comes to dental health and whiteness. Brushing and flossing your teeth twice a day can remove the plaque, food particles, and bacteria that can cause stains and cavities. Use a soft-bristled brush and fluoride toothpaste to avoid damaging the enamel or irritating the gums. Floss between your teeth and rinse with mouthwash to get rid of the debris and freshen your breath.

2. Do use a straw

Drinking coffee, tea, soda, or wine can stain your teeth over time, especially if you consume them frequently or in large amounts. To minimize the contact between the liquid and the teeth, use a straw when drinking, and swallow quickly. This way, you’ll protect your front teeth and reduce the risk of discoloration.

3. Do observe proper hygiene

Keeping your toothbrush, mouth guard, trays, or strips clean and dry is crucial for preventing bacteria buildup and contamination. Rinse them with water after each use and let them air dry. Store them in a clean and dry place, away from sunlight or heat. Replace your toothbrush every three to four months or sooner if the bristles are frayed or worn out.

4. Do maintain a healthy lifestyle

Smoking, drinking alcohol, or eating sugary or acidic foods can harm your teeth and gums and undermine the effects of teeth whitening. Therefore, it’s advisable to quit smoking, limit your alcohol intake, and eat a balanced and nutritious diet that includes calcium-rich foods, such as milk, cheese, and yogurt, that strengthen your teeth and bones.

The Don’ts

1. Don’t overdo it

Whitening your teeth too often or too aggressively can damage the enamel, cause sensitivity or pain, and make your teeth look unnaturally white or opaque. Follow the instructions carefully and don’t exceed the recommended time or amount. If you experience any discomfort or side effects, stop using the product and consult your dentist.

2. Don’t skip dental checkups

Regular dental checkups and cleanings are essential for maintaining good oral health and catching any dental problems early. Moreover, your dentist can assess your teeth and gums’ condition, recommend the best whitening method for you, and monitor your progress. Don’t neglect dental visits or postpone them, even if you’re using home whitening treatments.

3. Don’t rely on home remedies alone

While natural remedies can be effective and safe for mild teeth discoloration, they may not work for severe or deep stains or underlying dental issues. Moreover, home remedies may carry some risks or side effects if used incorrectly or excessively. Therefore, it’s crucial to consult your dentist and follow a personalized treatment plan that suits your needs and goals.

4. Don’t neglect oral hygiene

Whitening your teeth can enhance your smile’s aesthetics and boost your confidence, but it won’t solve any underlying dental problems or replace the need for proper oral hygiene. Neglecting brushing, flossing, and rinsing can lead to cavities, gum disease, bad breath, and other oral health issues that can harm your overall health as well. Make dental hygiene a daily habit and stick to it.
