These over-the-counter teeth whitening products come pretty close to giving you dentist office results

Professional teeth whitening at a dental office is the quickest and most effective method for brightening your smile, though it is often expensive and time-consuming. If you are considering over-the-counter (OTC) whitening products, there is a wide variety of choices available, including strips, gels, toothpastes, and mouthwashes. However, their effectiveness depends on the specific product, your adherence to the instructions, and your personal expectations.

To help you select a product that meets your needs, I consulted with dentists regarding the advantages and drawbacks of various OTC whitening treatments, including when you might expect to see visible changes in tooth shade. Using expert advice, I compiled a list of top-rated options from brands like Crest, Sensodyne, Act, and Colgate, many of which have been evaluated by our team.

All of the over-the-counter teeth whitening products listed below align with expert recommendations. I have included items that carry the American Dental Association’s Seal of Acceptance, products tested by our staff, award-winning treatments, and other highly regarded options.

Regardless of how many times our team evaluates whitening strips, Crest’s versions consistently rank highest because they are both effective and user-friendly. These strips feature a hydrogen peroxide gel coating and a non-slip design, which keeps them securely in place during use — I can hold full conversations while wearing them without any shifting, and they are thin enough to be barely noticeable. The strips are flexible, allowing them to conform to the curve of your teeth, yet they remain sturdy enough to avoid folding when removed from the packaging. This kit includes enough strips for 20 45-minute sessions and two 1-hour express treatments.

Former senior editor Lindsay Schneider finds that Opalescence whitening trays are simpler to apply than strips, as you simply bite into them to mold them to your teeth. “They’re so easy to pop on and off, and I find them comfortable to wear for longer periods of time,” says Schneider. Her dentist recommended these trays, which are worn for about 30 minutes and contain a professional-grade, 10% hydrogen peroxide mint gel. “I definitely see a difference when using these consistently — my teeth are noticeably whiter,” says Schneider. “Because they’re stronger, my teeth get a little sensitive when using them, but that’s the case with almost all whitening products for me.”

Opalescence whitening gel, designed for use in custom-made dental trays, offers professional-grade quality similar to their pre-filled trays. The primary active ingredient is carbamide peroxide, supplemented by hydrogen peroxide. The gel is sold in four concentrations—10%, 15%, 20%, and 35%—each requiring a different application time ranging from 30 minutes to overnight. It comes in syringes with a narrow tip, which helps you fill your trays without overflow. The gel is available in mint and melon flavors, as well as an unflavored version.

All of the whitening toothpastes listed below contain fluoride to help prevent cavities and strengthen enamel.

Every team member who tested this toothpaste reported the same result: it is remarkably effective. “My coffee-stained teeth started visibly whitening in just days, so much so that my dentist thought I’d gotten a professional treatment,” says editorial director Lauren Swanson. According to the manufacturer, this minty toothpaste uses hydrated silica to break down stain bonds and scrub them from the tooth surface. It is packaged in a pump dispenser, which helps control the amount used per brushing.

In addition to trays and gels, Opalescence produces a whitening toothpaste that is a favorite among our staff. The formula includes silica to gently lift surface stains, and after several weeks of use, editorial operations associate Jem Alabi noted that her teeth appeared visibly brighter. She also found that the toothpaste did not irritate her teeth, unlike other products she had previously tried. It features a gel-like consistency and a cool mint flavor.

Sensodyne offers some of our preferred toothpastes for sensitive teeth, and this particular version provides added whitening benefits. The formula utilizes hydrated silica to polish away stains, while stannous fluoride helps soothe sensitivity and fight cavities. “I’ve always had really sensitive teeth, especially to cold, and I’m always nervous to do whitening treatments,” says senior community manager Rosalie Sparaco. “Having a toothpaste that can help my teeth feel less sensitive to cold drinks while whitening is a win-win.” The toothpaste lathers well while brushing and has a refreshing peppermint and spearmint taste.

According to the brand, this whitening toothpaste provides up to 24 hours of antibacterial protection. The hydrated silica in the formula works to fade surface stains and yellowing, and regular use can also assist in managing plaque and tartar buildup. In my experience, the toothpaste has a pleasant mint flavor and does not produce a heavy foam during use.

ACT’s Whitening + Anticavity mouthwash utilizes hydrogen peroxide to brighten teeth and fluoride to guard against cavities. The brand notes that it is free of alcohol and dyes, and it includes a mint flavor to help freshen breath.

Colgate’s whitening pen contains a hydrogen peroxide gel and is designed similarly to a lipstick tube. You unscrew the integrated brush, dip it into the gel, and apply it directly to your teeth. Because the brush is quite small, you can target one tooth at a time to ensure complete coverage. The manufacturer suggests applying the quick-drying gel before bed, leaving it on overnight, and brushing it off the following morning.

There are seven primary categories of over-the-counter teeth whitening products to consider. To determine which is best for you, evaluate what fits your lifestyle, as these products only yield results if used consistently.

Whitening strips: These function like stickers for your upper and lower teeth, coated with a thin layer of a bleaching agent such as hydrogen peroxide. As the strips remain on your teeth, the ingredients penetrate the enamel to lighten it.

Whitening trays: These operate similarly to strips, but you bite into them rather than sticking them to the front of your teeth. Most trays come pre-filled with a whitening gel containing active bleaching agents; otherwise, you must fill them yourself before treatment.

Whitening gel with custom trays: OTC trays are one-size-fits-all, which some find uncomfortable or ineffective. Alternatively, your dentist can create custom trays that fit your mouth perfectly, and you can purchase professional-strength whitening gel to use with them. “Using custom whitening trays made by your dentist can isolate where the whitening material goes,” says Dr. Erin Fraundorf, the founder and orthodontist at Boca Orthodontic and Whitening Studio. “You can better control it to prevent it from touching your gum tissue.”

Whitening toothpaste: According to the ADA, whitening toothpastes primarily use abrasives rather than active bleaching agents to remove surface stains. While all toothpaste is mildly abrasive to clean teeth, whitening versions contain specific abrasives like sodium bicarbonate (baking soda) to target surface discoloration.

Whitening mouthwash: These rinses contain active bleaching ingredients that break down stains as you swish the liquid around your mouth.

Whitening pens: These are designed for quick, on-the-go brightening. They contain a gel made with active bleaching agents that you brush onto your teeth and leave on for a set duration.

LED light kits: Some strips and trays are bundled with an LED light, which many companies claim will accelerate the whitening process. However, the dentists I interviewed do not recommend them, so I have excluded them from this list. “Not all LED lights are created equal, and the ones included in at-home whitening kits are significantly weaker than those used in professional treatments,” says Fraundorf. “Whether or not you use an LED light with your at-home whitening kit, your results will be the same.”

According to the experts I consulted, OTC whitening strips, trays, and gels for custom trays are generally the most effective because they contain higher concentrations of active ingredients. The higher the concentration, the more potent the product. Dr. Matt Messina, an assistant professor at The Ohio State University College of Dentistry, notes that whitening toothpastes, mouthwashes, and pens typically have low concentrations of active ingredients, making their impact minimal. He suggests using these as maintenance tools following a more intensive treatment and notes they are ideal for beginners. If you are new to whitening or have a history of tooth sensitivity, start with products containing lower concentrations and increase them gradually if your teeth can tolerate it.

Hydrogen peroxide and carbamide peroxide are the two most common whitening agents found in both professional and over-the-counter dental products, according to the ADA. Experts explain that these active ingredients penetrate the tooth enamel to break down discoloration without thinning or softening the teeth.

Yes, over-the-counter whitening products can earn the ADA Seal of Acceptance, which is considered the gold standard for dental care. Brands may voluntarily submit data for review, and if the organization determines the product is safe and effective based on specific criteria, it receives the seal. A lack of the seal does not necessarily mean a product is ineffective; it simply means the brand has not submitted it for ADA evaluation.

There are two types of teeth whitening: mechanical and chemical.

Mechanical whitening removes exterior stains by physically scrubbing them away, says Fraundorf. Examples include brushing with an electric toothbrush, using a semi-abrasive whitening toothpaste, or using a water flosser.

Chemical whitening targets interior stains by bleaching them with active ingredients like hydrogen and carbamide peroxide. According to the ADA, these ingredients penetrate the enamel to reach interior tissues, lightening the tooth color from the inside out through a chemical reaction. While higher concentrations of these ingredients are more powerful, they also carry a greater risk of gum irritation and tooth sensitivity. Whitening strips and professional in-office treatments are examples of chemical whitening.

Yes, you can effectively whiten your teeth at home, but you should manage your expectations. OTC products are primarily designed to correct surface-level discoloration rather than deep, internal staining. Furthermore, they will not work if not used correctly and consistently. “Most people are not compliant at home and therefore do not get the results they are looking for,” says Dr. Ilona Casellini, the founder of and a dentist at Swiss Quality Smile. “In-office bleaching is more effective because you get instant gratification. In one session, patients usually get one to two shades lighter and all they have to do is relax while the dentist does the work.”

In-office treatments are more powerful because dentists utilize higher concentrations of active ingredients that work rapidly. It may take days or weeks to see results from lower-concentration OTC products, and you may see little improvement if your discoloration is caused by oral health issues like cavities or decay, which can turn teeth a dark gray, says Messina. The same applies to problems like gum irritation and plaque buildup.

Overall, whitening your teeth at home is safe. However, it is important to consult your dentist before beginning an OTC treatment, particularly if you have experienced gum or tooth sensitivity in the past. If you cannot tolerate highly concentrated agents, your dentist can help you identify a more suitable product.

While whitening at home, pay close attention to how your teeth feel, especially when trying a new product. If you experience any sensitivity in your gums or teeth, stop using the product immediately and reach out to your dentist.

The best way to ensure safety is to follow the product instructions precisely. “If it says 30 minutes, an hour isn’t better,” says Messina. “It may instead dramatically increase your tooth sensitivity, making it hard to handle cold things like ice cream or even water.”

Any dental product used incorrectly or excessively can cause damage. “Even though at-home bleaching products usually have a lower concentration of peroxide, if used excessively, it can cause your teeth to become dehydrated and brittle, not to mention overly sensitive,” says Casellini. To avoid this, follow the directions exactly and limit your usage. Additionally, maintain a standard oral care routine that includes brushing with fluoride toothpaste, flossing, and using mouthwash.

No, natural and DIY whitening methods do not work, according to the experts I interviewed. They have not been studied as extensively as professional or OTC options and can cause negative side effects, such as increasing sensitivity or reducing tooth hardness, per the ADA. Charcoal toothpaste is a common example; its abrasiveness can strip enamel over time, which Messina compares to sanding a floor. Other DIY treatments, such as creating pastes from vinegar, acidic fruits, or baking soda, as well as oil pulling with coconut oil, are not well-researched and are discouraged by the ADA and the dentists I consulted.

Teeth whitening is not suitable for everyone. People who are unhappy with their tooth color or wish to match their natural teeth to a bridge or crown are the best candidates, says Casellini. Conversely, those with veneers, crowns, or bridges that match their natural teeth should avoid whitening. Doing so can lead to mismatched colors, as the natural teeth will lighten while the prosthetics remain the same shade.

Additionally, if you have a history of dental issues such as cracks, chips, untreated cavities, severe sensitivity, or gum recession, you should avoid OTC whitening products, says Fraundorf. Consult your dentist, who may be able to tailor an in-office treatment to your specific needs.

There are numerous reasons why teeth develop interior and exterior stains over time. Interior stains are typically caused by genetics and aging, which cannot be prevented, while exterior surface stains are often linked to tobacco use and the consumption of pigmented foods, which can be managed to some extent, says Casellini.

Fraundorf outlined some of the most common causes of tooth discoloration below. To determine the specific cause of your staining, consult your dentist.

Poor oral hygiene: Your teeth are more likely to yellow if you do not brush twice daily for two minutes, floss at least once a day, use fluoride toothpaste, and visit your dentist every six months for a cleaning.

Diet: “If it can stain a white T-shirt, it can stain your teeth,” says Fraundorf. Beverages and foods like tea, coffee, red wine, sports drinks, sodas, berries, curry, and tomatoes contain pigments that cling to enamel and cause surface stains.

Genetics: Teeth have a genetic component inherited from your family, meaning you may be naturally predisposed to having less white teeth.

Thin or worn enamel: The layer beneath the enamel, known as dentin, is yellow-brown in color. If your enamel is translucent or thin, the dentin may be more visible. Enamel wears down over time due to aging, grinding, chewing, and consuming acidic foods or drinks.

Smoking: Nicotine from cigarettes leaves heavy brown and yellow surface stains on the teeth.

Medication use and tooth trauma: Certain medications or physical trauma to the teeth can make you more susceptible to discoloration.

The easiest ways to prevent yellowing and staining are to practice good oral hygiene and limit your intake of highly pigmented foods and drinks. If you consume dark beverages like tea or coffee, use a straw to minimize contact with your teeth and rinse with plain water afterward, says Fraundorf. Also, try to choose flat water over sparkling, as it is less acidic. Dentists also recommend avoiding tobacco products.
