Can yellow teeth become white again? Are home teeth whitening kits worth it?

Although all teeth are beautiful, there’s nothing like a pearly white smile when you’re meeting someone for the first time. That said, taking multiple trips to the dentist for teeth whitening sessions isn’t always doable or affordable—enter teeth whitening kits. Teeth whitening kits are often cheaper and require less effort while producing satisfactory results.

“People are always looking to improve their smile and look their best,” says Gary Liu, DMD, board-certified pediatric dentist at Kind Smiles in Irvine, California. “Teeth whitening kits are great options to whiten yellowing teeth from natural aging and stains from drinking coffee or tea.”

In addition to Dr. Liu, I tapped Lauren Becker, DDS, New York City-based general and cosmetic dentist, and Alice Hoang, DMD, FAGD, FICOI, a general dentist at Brooklyn Mint Dental to find the best teeth whitening kits on the market keeping ingredients, duration, frequency, and type in mind.

What to look for when buying teeth whitening kits

Ingredients

It’s important to know about the ingredients in teeth whitening kits to ensure you choose those that will do more good than harm when whitening your teeth. That said, Dr. Liu notes it often takes a combination of ingredients including hydrogen peroxide or carbamide peroxide to bleach or oxidize the colored particles found on teeth and make them appear whiter. When shopping for teeth whitening kits, you’ll notice most contain hydrogen or carbamide peroxide as they are the stronger bleaching agents. However, it’s important to note that higher percentages of hydrogen peroxide (35%) and carbamide peroxide (22%), are more likely to cause teeth sensitivity, adds Dr. Liu. In addition to hydrogen peroxide and carbamide peroxide, Dr. Becker and Dr. Liu add that potassium nitrate and fluoride are other common ingredients in many teeth whitening kits.

As far as ingredients to avoid when shopping for teeth whitening kits go, Dr. Liu advises avoiding phthalimido-peroxy-caproic acid (PAP) and instead opting for products containing PAP+. Furthermore, Dr. Becker notes charcoal is not an ingredient that should be applied to teeth for whitening purposes as it can erode enamel and weaken teeth. A best practice is to avoid products containing triethanolamine, sodium chloride, and urea peroxide, adds Dr. Hoang.

Type

Not all teeth whitening kits are created equal. Some of the most common teeth whitening kits are toothpaste, gels, trays, pens, or LED-based. I recommend reading through the list of pros and cons of each (provided below) to better understand each kind.

Duration and frequency

Duration and frequency are essential to consider when reviewing the best teeth whitening kits as different kits are accompanied by different instructions. Toothpaste-based whitening kits typically require less time with each use or session. However, they’re often advised to be used daily as a result. On the other hand, teeth whitening trays and LED-based kits are often recommended to be used for longer periods but need fewer treatments and produce longer-lasting results, as they tend to be stronger.

How we selected the best teeth whitening kits

Expert advice

I chose the best teeth whitening kits considering the insights and recommendations of full-time New York and California dentists. When interviewing dentists, I asked them what people should look for in a teeth whitening kit regarding type, frequency, duration, and ingredients. They also recommended teeth whitening kits of various kinds including trays, toothpastes, strips, and more.

Easy application

Since the thought of adding a step to your dental hygiene routine may feel overwhelming, especially if you haven’t used a similar product before or you don’t have a lot of free time, I specifically chose ones with straightforward directions that many people can understand and ones that don’t require a great deal of effort to use and obtain results.

Ingredients

Since my experts recommended whitening kits containing hydrogen or carbamide peroxide, most of my picks contain these active ingredients.

Types

Different people prefer different kinds of kits so I made sure to include those that are LED, toothpaste, strips, and pens.

Types of teeth whitening kits

There are many teeth whitening kits on the market. To determine which one best fits your dental needs, you should know their pros and cons.

Toothpaste

Dr. Liu notes that whitening toothpastes containing peroxides can whiten teeth, but usually do so at a slower rate and require more consistent and routine use as the whitening agent only covers teeth for a couple of minutes during each use.

Gels

According to Dr. Liu, gel-based whitening kits often whiten teeth more effectively as the trays that are typically used can more effectively cover one’s teeth.

Strips

Whitening strips are often easy to use as they simply stick onto teeth and can usually be pulled off effortlessly. “These are the safest and most effective teeth whitening kits you can buy at home,” explains Dr. Liu.

Pens

Whitening pens can be a viable option for those looking for compact teeth whitening kits that can be put in a bag and are easily accessible while traveling. However, “they take longer to whiten, since the gels wash out faster without a tray or strip to hold the gels in place,” explains Dr. Liu.

LED

LED-based teeth whitening kits may work faster to improve teeth color as they “activate the peroxide gels to accelerate the whitening effect,” says Dr. Liu. However, if you have sensitive teeth or are trying to whiten your teeth without developing sensitivity issues, these kinds of kits may cause sensitivity issues as a result of how quickly they work.

How to use a teeth whitening kit

How you use a teeth whitening kit will vary depending on the type you select. For example, many toothpaste-based teeth whitening kits instruct people to use them once or twice per day or as directed by their dentist and only require them to put some toothpaste onto their brush and brush. On the other hand, other teeth whitening kits require two or more steps such as applying a gel with a teeth whitening pen before LED lights or squirting whitening gel into a tray before placing it into the mouth for a recommended time. Regardless of the kit used, a best practice is to thoroughly read the directions and speak with your dentist before using.

Frequently asked questions (FAQs)

What is the most effective product to whiten teeth?

According to Dr. Becker, there isn’t one specific product that’s most effective at whitening teeth as every person differs regarding how well they upkeep their teeth and their sensitivity level. The product that’s most effective at whitening teeth for one person may not provide the same results for another.

Can yellow teeth become white again?

Whether yellow teeth can become white again will vary by individual. Dr. Becker notes that the cause of teeth discoloration often plays a big role in whether yellow teeth can whiten. “Most yellow teeth can become whiter and lighter with a good tooth whitening regimen. However, intrinsic stains from long-term antibiotic use, cavities, and previous root canal treatment cannot be whitened by dental teeth whitening,” notes Dr. Liu.

Are home teeth whitening kits worth it?

According to Dr. Liu, home teeth whitening kits can be worth it depending on your unique circumstances and if you’re willing (and able to) to wait a bit longer to see results. “They [home kits] have comparable results to dentist-prescribed teeth whitening trays, but may take longer to achieve the same results,” explains Dr. Liu. With this in mind, it’s always best to speak with your dentist to see which whitening option best suits your dental needs.
