How At-Home Teeth Whitening Kits Work and What Are the Main Types

At-home teeth whitening kits are products that you can buy online or in stores, and use by yourself at home, following the instructions provided by the manufacturer. They usually contain a whitening agent, such as hydrogen peroxide or carbamide peroxide, that penetrates the enamel and breaks down the stains that cause discoloration.

Depending on the type of kit, the whitening agent may be applied directly to the teeth, or with the help of a device such as a tray, a strip, or a light.

The main types of at-home teeth whitening kits are:

Whitening strips:

These are thin, flexible strips that are coated with a whitening gel. You apply them to your teeth and leave them on for a specified amount of time, usually between 10 to 30 minutes. The strips adhere to your teeth and deliver the whitening agent to the surface. Some strips may also have a blue light that activates the gel and enhances the results.

Whitening trays:

These are plastic trays that are filled with a whitening gel. You place them over your teeth and wear them for a certain period of time, usually between 15 to 60 minutes. The trays mold to your teeth and hold the gel in contact with them. Some trays may also come with a LED light that boosts the whitening effect.

Whitening gels:

These are gels that contain a high concentration of peroxide. You apply them directly to your teeth using a syringe, a brush, or a pen. You leave them on for a few minutes, then rinse them off. Some gels may also require you to use a mouthguard or a light to protect your gums and enhance the outcome.

Whitening pens:

These are pens that have a tip that dispenses a small amount of whitening gel. You twist or click the pen to release the gel, then brush it onto your teeth. You leave it on for about 10 minutes, then wipe it off. Some pens may also have a light that activates the gel and improves the results.

What Are the Benefits and Drawbacks of Using At-Home Teeth Whitening Kits?

At-home teeth whitening kits have some advantages and disadvantages that you should consider before buying and using them. Here are some of them:

Benefits

  • They are affordable: Compared to professional whitening treatments that can cost hundreds or thousands of dollars, at-home kits are much cheaper and more accessible. You can find them for as low as $10 or as high as $100, depending on the type and quality of the product.
  • They are convenient: You can use them whenever and wherever you want, without having to make an appointment or visit a dentist. You can also choose how often and how long you want to whiten your teeth, depending on your goals and preferences.
  • They are effective: Most at-home kits can whiten your teeth by several shades in a matter of days or weeks, depending on the strength of the product and how often you use it. Some kits may even give you noticeable results after one use.

Drawbacks

  • They are not as powerful: At-home kits have lower concentrations of peroxide than professional treatments, which means they may not be able to remove deep or stubborn stains. They may also take longer to achieve your desired shade of white.
  • They are not as safe: At-home kits may cause side effects such as tooth sensitivity, gum irritation, enamel damage, or uneven results if used incorrectly or excessively. They may also interact with other dental conditions or treatments, such as fillings, crowns, veneers, or braces. Therefore, it is important to follow the instructions carefully and consult your dentist before using them.
  • They are not permanent: At-home kits can only whiten your teeth temporarily, as they do not change the color of your dentin, the inner layer of your teeth. Your teeth may also become stained again over time due to factors such as aging, smoking, or consuming certain foods and drinks. Therefore, you may need to repeat the treatment periodically to maintain your results.

How to Choose the Best Kit for Your Needs and Budget?

With so many options available on the market, it can be hard to decide which at-home teeth whitening kit is best for you. Here are some tips to help you make an informed choice:

Check the ingredients:

Look for products that contain peroxide as the main whitening agent, as it is proven to be effective and safe when used properly. Avoid products that contain other ingredients that may be harmful or ineffective, such as chlorine dioxide, sodium chlorite, or sodium bicarbonate.

Check the concentration:

Look for products that have a peroxide concentration between 10% to 35%, depending on your sensitivity and desired results. Higher concentrations may whiten your teeth faster and more effectively, but they may also cause more side effects and damage. Lower concentrations may be gentler and safer, but they may also take longer and require more applications.

Check the reviews:

Look for products that have positive feedback from other users who have tried them. Read the reviews carefully and look for information about the effectiveness, safety, comfort, ease of use, and value of the product. Also, look for before and after photos or videos that show the actual results of the product.

Check the price:

Look for products that fit your budget and offer a good value for your money. Compare the prices of different products and look for discounts or deals that may save you some cash. Also, consider the quality and quantity of the product, as well as the duration and frequency of the treatment.

How to Use Them Safely and Effectively

Once you have chosen your at-home teeth whitening kit, you need to use it correctly to get the best results and avoid any problems. Here are some general guidelines to follow:

Read the instructions:

Before using any product, make sure you read and understand the instructions provided by the manufacturer. Follow them carefully and do not deviate from them. Pay attention to details such as how much product to use, how long to leave it on, how often to apply it, and how to store it.

Prepare your teeth:

Before applying any product, make sure your teeth are clean and dry. Brush and floss your teeth thoroughly to remove any plaque or debris that may interfere with the whitening process. You may also want to avoid eating or drinking anything that may stain your teeth for a few hours before or after the treatment.

Protect your gums:

Before applying any product, make sure you protect your gums from any contact with the whitening agent. You can do this by using a cotton swab or a finger to apply some petroleum jelly or lip balm along your gum line. You can also use a mouthguard or a tray that fits your teeth well and does not leak any gel onto your gums.

Apply the product:

Depending on the type of product you are using, you may need to apply it directly to your teeth or with a device such as a strip, a tray, or a light. Make sure you apply it evenly and cover all of your teeth that you want to whiten. Avoid getting any product on your lips, tongue, cheeks, or throat.

Wait for the product to work:

Depending on the type and strength of the product you are using, you may need to wait for a few minutes or up to an hour for it to work. Do not eat, drink, smoke, or talk while you are waiting. If you are using a light device, make sure you keep it close to your mouth and do not look directly at it.

Remove the product:

After the specified time has passed, remove the product from your teeth by rinsing your mouth with water or wiping it off with a tissue. If you are using a strip or a tray, peel it off gently and discard it properly. If you are using a gel or a pen, brush your teeth gently with water or a mild toothpaste.

Repeat the treatment:

Depending on your goals and preferences, you may need to repeat the treatment once or twice a day for several days or weeks until you achieve your desired shade of white. Do not exceed the recommended frequency or duration of the treatment, as this may cause more harm than good.

Maintain your results:

To keep your teeth white for longer, you need to take care of them properly after the treatment. Brush and floss your teeth regularly with fluoride toothpaste to prevent plaque buildup and decay. Avoid or limit or minimize your consumption of foods and drinks that may stain your teeth, such as coffee, tea, wine, berries, or sauces.

You may also want to use a whitening toothpaste or mouthwash occasionally to remove any surface stains and refresh your smile. If your teeth start to lose their brightness, you can repeat the treatment every few months or as needed.

What Are Some Other Ways to Whiten Your Teeth Naturally or Professionally?

If you are not satisfied with the results of at-home teeth whitening kits, or if you want to try something different, you may want to explore some other options to whiten your teeth. Here are some of them:

Natural Remedies

Some people swear by using natural remedies to whiten their teeth, such as baking soda, hydrogen peroxide, apple cider vinegar, lemon juice, coconut oil, or activated charcoal. These substances may have some bleaching or abrasive properties that may help remove some stains and plaque from your teeth. However, there is not enough scientific evidence to support their effectiveness and safety, and they may also cause damage to your enamel or gums if used incorrectly or excessively. Therefore, you should be cautious and consult your dentist before trying any of these methods.

Professional Treatments

If you want to get the best and fastest results possible, you may want to opt for a professional whitening treatment performed by a dentist or a dental hygienist. These treatments use higher concentrations of peroxide and more advanced techniques and equipment to whiten your teeth in a controlled and safe environment. They can also customize the treatment according to your needs and preferences, and address any issues or concerns you may have. Some of the most common professional whitening treatments are:

  • In-office whitening: This is the most effective and expensive option, as it can whiten your teeth by up to 10 shades in one hour. The dentist will apply a protective gel or a rubber shield to your gums, then apply a high concentration of peroxide gel to your teeth. They will then use a special light or a laser to activate the gel and speed up the whitening process. You may need one or more sessions depending on your goals and the condition of your teeth.
  • Take-home whitening: This is a more affordable and convenient option, as it allows you to whiten your teeth at home using a custom-made tray and a lower concentration of peroxide gel provided by the dentist. You will need to wear the tray for a few hours a day for several days or weeks until you achieve your desired shade of white. The dentist will monitor your progress and adjust the treatment as needed.
  • Whitening products: This is the least effective and cheapest option, as it involves using over-the-counter products such as whitening toothpastes, mouthwashes, strips, trays, gels, or pens that you can buy online or in stores. These products have lower concentrations of peroxide than professional treatments, and they may not be able to whiten your teeth evenly or deeply. They may also cause side effects such as sensitivity or irritation if used incorrectly or excessively.

At-home teeth whitening kits are popular products that can help you improve the appearance of your smile by removing stains and whitening your teeth in the comfort of your own home. They have some benefits such as being affordable, convenient, and effective, but they also have some drawbacks such as being not as powerful, safe, or permanent as professional treatments.

Therefore, you need to choose the best kit for your needs and budget, use it safely and effectively, and maintain your results properly. You may also want to consider some other ways to whiten your teeth naturally or professionally if you are not happy with the results of at-home kits.
