11 Best Teeth Whitening Kits for Stubborn Stains

There are different ways to whiten your teeth, like toothpaste, strips, and lasers. If you’re interested in teeth whitening kits, you’re in the right place! In this article, we’ll give you info on these kits and list some of the best ones for home use.

Before we get into the product list, let’s first understand what teeth whitening kits are and how they work. Dr. Stephanie Dumanian, a cosmetic dentist, makes it simple: “Whitening kits are a convenient way to remove surface stains from your teeth. They also help keep your teeth white after previous whitening treatments.”

But not all kits work the same way. Dr. Daniel Rubinshtein, another cosmetic dentist, says that most at-home whitening kits use hydrogen peroxide or carbamide peroxide to remove stains when used correctly. So, to get good results, look for kits with these ingredients.

If you prefer options without peroxide, don’t worry; there are effective alternatives. Keep reading to find some of the best teeth whitening kits on the market.

What to consider when picking a teeth whitening product

  1. Active Ingredients: Look for products with hydrogen or carbamide peroxide as their active lightening ingredients, according to Dr. Sharon Huang, a cosmetic dentist. Hydrogen peroxide delivers great results but may cause temporary tooth sensitivity, warns Dr. Gonchar.

  2. Potency Level: Over-the-counter products usually have up to 10% active lightening ingredients, as noted by Dr. Huang. Higher concentrations work faster but might lead to tooth sensitivity, so be cautious. Lower concentrations are better for sensitive teeth or specific dental needs.

  3. Sensitivity-Friendly Ingredients: If you have sensitive teeth, consider carbamide peroxide, which is less likely to cause sensitivity than hydrogen peroxide due to its slower action. Some peroxide-free products use natural ingredients like aloe vera and coconut oil for gentle stain removal, although they may not be as potent as peroxide.

  4. Form: Dr. Huang recommends whitening strips because they conform to your teeth, ensuring constant contact with the whitening solution and making them easier to use for the recommended duration.

How do the ingredients in teeth-whitening products work?

It’s all about peroxide. Dr. Messina says peroxide creates the bubbling action. So, when you use a whitening kit, you’ll usually find either hydrogen peroxide or carbamide peroxide as the active ingredient (carbamide peroxide is a milder form of hydrogen peroxide).

Dr. Neil Hadaegh, a cosmetic dentist in Beverly Hills, prefers carbamide peroxide because it’s stable, meaning it keeps its quality and consistency when you use it.

Besides peroxide, Dr. Messina mentions that over-the-counter whitening products often have other ingredients to make them taste better.

Types of Teeth Whitening Kits

  1. Gel: Whitening gel is a common component in many kits. It’s used in LED kits, pens, and trays. These gels usually contain hydrogen or carbamide peroxide.

  2. LED: LED devices are popular and use peroxide gel activated by LED technology. This speeds up whitening through oxidation. Be cautious as LED devices may have side effects like tissue damage.

  3. Pens: Whitening pens are handy and have a peroxide gel applied with a brush. They often have lower peroxide concentrations but are easy for on-the-go use.

  4. Toothpaste: Whitening toothpaste has peroxide in a lower concentration than other products. Dr. Velayo suggests checking the relative dentin abrasion (RDA) for better whitening. Higher RDA means more effective whitening.

Remember that results may vary between these options, so choose the one that suits your needs and preferences best. I personally use the PurelyWhite Deluxe Teeth Whitening Kit for whitening my teeth.

Which Teeth Whitening Kits Do Dentists Recommend?

Dentists advise choosing teeth whitening products that balance peroxide concentration and usage duration for effective results. Dr. Velayo notes that products with short usage times, like toothpaste, usually don’t whiten significantly and may have unwanted ingredients.

Charcoal toothpaste and whitening products have become trendy, but Dr. Cindy Roark from Sage Dental warns against them. Charcoal products use abrasion to remove stains, but they can wear down your tooth enamel. Enamel is naturally clear, and as it wears away, your teeth may appear yellower. So, Dr. Roark suggests being cautious with charcoal products to protect your enamel and maintain a bright smile.

Ingredients to Look for in Teeth Whitening Kits

When shopping for teeth whitening kits, focus on these key ingredients:

  1. Peroxide: Look for hydrogen or carbamide peroxide. These compounds effectively remove stains on the surface and within your teeth.

  2. Additional Comfort Ingredients: Consider ingredients like potassium nitrate, fluoride, and/or xylitol. They can help reduce discomfort, especially if you have sensitive teeth, according to Dr. Velayo.

But be cautious about a newer ingredient in some kits called PAP (phthalimido-peroxy-caproic acid). Dr. Edmond R. Hewlett from UCLA School of Dentistry warns that PAP might lead to lasting sensitivity, so it’s best to avoid products with this ingredient.

What makes in-office teeth whitening different from over-the-counter options?

Both in-office and over-the-counter whitening treatments use peroxide as the main ingredient, but there’s a key distinction: concentration. In a dental office, they can use a stronger whitening agent because they can protect the gums. They can carefully shield the gum tissue to ensure that the powerful whitening agent only touches the teeth. This is because professionals can take all the necessary precautions to safeguard the gums and focus the whitening agent exclusively on the enamel.

On the other hand, over-the-counter products have to be cautious about potential gum contact or accidental ingestion. So, they use a lower concentration of the active ingredient to avoid any harm to the gums. Dr. Messina mentions that, if you follow the manufacturer’s instructions, over-the-counter peroxide-based whiteners can still provide similar results. Typically, you might use them daily for 7 to 10 days initially, and then once every other week for maintenance.

Is LED light good for teeth whitening?

Yes, it can be very effective! LED light helps activate the whitening agent on your teeth. This process breaks down stains from food, drinks, and smoking. Dr. Wei adds that the light lets the bleaching agent go deep into your teeth, removing discoloration and speeding up the whitening.

But remember, using LED light alone won’t magically whiten your teeth. Dr. Gonchar says LED lights themselves don’t whiten; they work with agents like hydrogen peroxide to make whitening faster and better. The good news is LED lights are safe for your teeth and won’t harm them, but if your teeth are sensitive, it’s best to avoid using them.

How long does teeth whitening last?

It depends on whether you get professional treatment and your daily habits.

Professional Whitening: If you go pro, your results usually last longer. People typically do touch-ups every six months to a year to keep their smile white.

At-Home Products: Using products like whitening strips at home might require more frequent touch-ups, maybe every month, to remove surface stains and maintain whiteness.

Your lifestyle matters too. What you eat, drink, and whether you smoke affects how long your whitening lasts. Avoiding teeth-staining stuff and using whitening touch-up products can make your results stick around.

Common teeth-staining culprits include tea (it stains more than coffee), tobacco, and red wine. Dark foods and juices like turmeric, beets, curry, and blueberries can also stain. To prevent staining, use a straw for colored drinks or rinse with water right after (don’t brush immediately, as your enamel is softer and more prone to staining).

Are teeth whiteners safe?

Yes, they’re usually safe. But, you need to watch the ingredient concentration. When they use lower amounts, it’s safe and works. But if it’s a higher amount, there’s a risk of gum damage or tooth sensitivity. So, follow the instructions to be safe while using them.

Can I whiten my sensitive teeth?

Yes, you can, but be cautious. Teeth sensitivity during whitening is usually temporary and happens because the process can dry out your teeth. As they rehydrate, sensitivity usually goes away.

Before whitening, visit your dentist, especially if you have tooth decay. They can give the go-ahead if your oral health is good.

If your teeth are healthy and straight, you can try over-the-counter whitening products. But if they don’t work well, see your dentist. They can offer stronger and safe whitening options.

During whitening, watch for two signs: lasting sensitivity after 48 hours and gum irritation. If you have either, space out your whitening sessions for comfort and safety.
