Teeth whitening kits FAQs

What are the main types of teeth whitening kits?

Teeth whitening kits can include whitening pens, powders, gels and strips. Strips are applied straight onto your teeth after you’ve brushed them, while powders can be applied with a toothbrush. Alternatively, whitening pens are portable and easy to use when you’re on the go. Some whitening treatments will come with a mouth tray and an LED light, which helps to speed up the whitening effect.

What ingredients should you look for in a teeth whitening kit?

Hydrogen peroxide and carbamide peroxide are common active ingredients because of their bleaching effect on teeth. While at-home kits contain lower concentrations of peroxide than teeth whitening treatments from dentists, some people may be wary of the risks of using peroxide at home.

These can include issues around sensitivity, which are caused by damage to the tooth enamel. If you want to go peroxide-free, consider formulas with other active ingredients, such as phthalimidoperoxycaproic acid, pentasodium triphosphate, sodium chlorite or coconut oil, among others.

Does whitening damage teeth?

To ensure your at-home teeth whitening is safe, follow the directions carefully. Don’t leave the solution on longer than the brand advises, as this may irritate gums. If so, stop the treatment. It’s also recommended that pregnant or breastfeeding women should not use teeth whitening kits.

Are there any natural alternatives to teeth whitening?

Activated charcoal is a less synthetic solution than hydrogen peroxide. However, some sources say charcoal’s abrasive texture could wear down tooth enamel, so while it can whiten teeth, it can also damage them.

How long will it take to whiten my teeth?

The amount of time it will take to whiten teeth will depend on the product and the amount of staining on your teeth. With most solutions, you’ll notice a difference after two weeks.

How often can you whiten your teeth?

You can top up your whitening when you feel the initial effect has started to fade. How long this will take depends on your diet and dental care. Always check the instructions on the package, as each kit is different, and overuse of whitening kits can cause tooth sensitivity, inflamed gums and enamel erosion.

Do LED teeth whitening kits work?

These kits use light-emitting diodes (LEDs) to emit ultraviolet and infrared light. These lights, particularly UV light, activate teeth whitening agents – gels, for example – and are said to make them work faster. So, while the LED itself doesn’t whiten teeth, Dr Patel says “it helps speed up the whitening process”.

Do teeth whitening strips work?

Teeth whitening strips work, but Dr Patel says “The results depend on the brand and how stained your teeth are to begin with.” He explained that while peroxide-based strips can brighten teeth over time, he warns that “They’re usually more effective for surface stains, rather than deep discolouration.”

Is teeth whitening safe?

Across both LED and strip-based teeth whitening, Dr Patel agrees that opting for a reputable brand and following its guidelines is crucial. “Some kits contain stronger whitening agents that could cause irritation or sensitivity, especially if used too often. It’s good to start slow,” he says.

What causes teeth staining?

Many things cause teeth staining. Dr Patel warns against:

• Tea and coffee – “Tannins in these drinks stick to enamel and cause yellowing.”

• Red wine – “The deep colour and acidity can stain teeth over time.”

• Smoking – “Nicotine and tar turn teeth yellow and brown.”

• Sugary and acidic foods – “These weaken enamel, making teeth more prone to staining.”

• Poor oral hygiene – “If plaque builds up, stains can set in more easily.”

• Ageing – “Enamel naturally wears down over time, making the yellowish dentin underneath more visible.”

What can you eat and drink after teeth whitening?

Annoyingly, you need to be careful after teeth whitening, confirms Patel. “After whitening, your teeth are more porous, so it’s best to avoid stain-causing foods and drinks (like coffee, tea, red wine, and curry) for at least 24-48 hours. Stick to lighter-coloured foods like chicken, rice, and dairy, if you want to be extra careful.”

The verdict: Teeth whitening kits

Overall, Smilepro’s LED and pen kit emerged as the best teeth whitening product, offering great value and effectiveness. Spotlight Oral Care’s strips and LED kit came in a close second, delivering noticeable results at a slightly higher price. For an affordable and quick solution, Colgate’s max white treatment was a strong contender. Meanwhile, Hismile provided an instant glow, and Icy Bear gave a pearly white finish, although neither kit led to a dramatic difference or long-lasting brightness.

Whitening Strips: A Comprehensive Review

In the pursuit of a brighter, whiter smile, the quest for effective teeth-whitening solutions has led many to explore the realm of at-home treatments. In a world where beaming smiles are coveted, individuals increasingly turn to convenient and cost-effective alternatives, eschewing pricier in-office treatments at the dentist's office. With the rise of at-home whitening options, Amazon has become a hub for an array of teeth-whitening strips, promising dazzling results without the hefty price tag. In this comprehensive guide, I delve into a side-by-side comparison of seven of the most popular whitening strips available on Amazon, shedding light on the key factors to consider when navigating the diverse landscape of at-home teeth-whitening solutions. Whether you're a seasoned teeth-whitening enthusiast or a newcomer seeking a radiant smile, understanding these essential criteria will empower you to make an informed choice for a brighter, more confident you.

When comparing teeth whitening strips, it's crucial to consider several factors:

1. Active Ingredients: Look for strips that contain peroxide-based ingredients like hydrogen peroxide or carbamide peroxide, known for their whitening properties.

2. Concentration of Active Ingredients: Higher concentrations of peroxide may lead to faster results but can also increase the risk of tooth sensitivity or gum irritation. Lower concentrations may offer a safer but slower approach.

3. Adhesive Quality: The effectiveness of whitening strips often depends on how well they adhere to your teeth. Strips that stay in place without sliding around or losing adhesion tend to provide more consistent results.

4. Ease of Use: Consider the convenience and ease of application. Some strips might be easier to apply and remove than others.

5. Sensitivity: Whitening strips can sometimes cause tooth sensitivity or gum irritation. Choose strips that are less likely to cause discomfort, especially if you have sensitive teeth.

6. Reviews and Recommendations: Look for reviews from reputable sources or dental professionals to gain insight into the effectiveness and safety of these products.

Understanding active ingredients in Teeth Whitening Strips

Teeth whitening strips typically rely on various active ingredients to lift stains and brighten enamel. Let's delve into some common whitening agents and their efficacy:

1. Hydrogen Peroxide:

• Efficacy: Hydrogen peroxide is a well-established and widely used whitening agent. It works by breaking down stains into smaller, less concentrated particles, leading to a brighter smile.

• Concentration: Strips with hydrogen peroxide often come in varying concentrations. Higher concentrations may deliver faster results but could increase the risk of tooth sensitivity.

2. Carbamide Peroxide:

• Efficacy: Carbamide peroxide breaks down into hydrogen peroxide when applied. It is effective for teeth whitening and is often found in at-home whitening products.

• Gentleness: Carbamide peroxide is considered gentler than hydrogen peroxide, making it a good choice for those with sensitive teeth.

3. Phthalimidoperoxycaproic Acid (PAP):

• Efficacy: PAP is a newer whitening agent that has shown promise in delivering effective results. It works similarly to hydrogen peroxide by breaking down stains.

• Sensitivity: PAP is generally considered less likely to cause sensitivity compared to traditional peroxides.

4. Dead Sea Salt:

• Efficacy: Dead Sea salt is often included for its natural abrasive properties. While it can help remove surface stains, it might not penetrate as deeply as peroxide-based agents.

• Mild Whitening: Dead Sea salt is suitable for mild whitening and is often used in more natural or organic whitening products.

5. Lemon Peel Oil:

• Efficacy: Lemon peel oil contains natural citric acid, which may help remove surface stains. However, its effectiveness for deep whitening might be limited.

• Caution: Citric acid can be acidic and may contribute to tooth sensitivity. Products containing lemon peel oil should be used with caution.

Choosing the Right Whitening Strips:

• Consider Your Sensitivity: If you have sensitive teeth, you might want to opt for products with lower concentrations of peroxide or alternative ingredients like PAP.

• Personal Preferences: Some individuals prefer natural ingredients like dead sea salt or lemon peel oil for a milder approach. However, their efficacy might vary compared to peroxide-based options.

• Consult with a Professional: Before choosing a teeth whitening strip, consult with your dentist or dental professional. They can provide personalized recommendations based on your oral health and preferences.

Understanding the active ingredients in teeth whitening strips empowers you to make an informed decision based on your unique needs and preferences. Always follow product instructions, and if you experience any discomfort, consult with a dental professional.

In my testing, Ollie and Crest emerged as the most effective whitening strips, considering their ingredient concentrations and performance. Ollie stands out as the only strip containing potassium nitrate, making it suitable for sensitive teeth. While preferences may vary, these two options offer reliable whitening with careful consideration of potential sensitivity issues.

For more detailed information of each specific product, I recommend checking each product's official website, reading customer reviews, consulting with dental professionals, or referring to dental associations or reputable dental resources that might offer comparative analyses of various whitening strips. This approach will help you make a more informed decision tailored to your individual dental needs and preferences.
