In the pursuit of a dazzling, whiter smile, Crest Whitening Strips have emerged as a popular and accessible at-home teeth whitening solution. Known for their ease of use and effective results, these strips are a go-to for many looking to improve the appearance of their teeth. 

However, the journey to a brighter smile involves more than just purchasing a box of whitening strips. Understanding how Crest Whitening Strips work, their availability in the UK, and how to use them effectively is crucial for achieving the best possible outcome.

In this article, we’ll explore everything you need to know about Crest Whitening Strips in the UK, covering key aspects such as their functionality, safety, accessibility, and tips for achieving optimal results.

What Are Crest Whitening Strips?

They are thin, flexible plastic strips coated with a whitening gel that contains peroxide, the active ingredient responsible for lightening stains on the teeth. These strips are designed to conform to the shape of your teeth, delivering the whitening gel directly to the enamel. Unlike other whitening methods, Crest strips are easy to apply and remove, making them a convenient choice for people who want to whiten their teeth without the hassle of dental appointments.

There are different versions of Strips available, each offering varying degrees of whitening power and treatment times. Some common options include:

3D White Professional Effects Crest: These strips claim to remove up to 14 years of stains, offering professional-level whitening results in just 20 days.

Crest 3D White Luxe Glamorous White: With a more affordable price point, these strips promise to remove stains and deliver noticeable whitening in as little as two weeks.

Crest 3D Whitestrips Gentle Routine: Designed for people with sensitive teeth, these strips provide a milder whitening experience that gradually improves tooth color over a longer period.

How Do Crest Whitening Strips Work?

Crest Whitening Strips use hydrogen peroxide or carbamide peroxide as the active ingredients to whiten teeth. These chemicals work by breaking down stains on the enamel, which are often caused by foods, drinks like coffee or wine, and smoking. When the strips are applied to the teeth, the peroxide penetrates the enamel and breaks apart the molecules causing the stains, resulting in a whiter appearance.

The strips are left on the teeth for 20 to 30 minutes, depending on the specific product, and the treatment is usually repeated daily for several days to achieve the desired result. It’s important to follow the instructions carefully to avoid overuse, which could lead to tooth sensitivity or gum irritation.

Are Crest Whitening Strips Available in the UK?

While they are widely available in the United States, their availability in the UK is more limited due to stricter regulations on the concentration of hydrogen peroxide in at-home whitening products. In the UK, teeth whitening products sold over the counter cannot contain more than 0.1% hydrogen peroxide. However, Crest Whitening Strips sold in the US often contain higher concentrations, typically around 6% to 10%.

Despite these regulations, many UK consumers still purchase Crest Whitening Strips online through platforms like Amazon or eBay, where they are often imported from the US. Some UK retailers also sell Crest products unofficially, but buyers should be cautious to ensure they are purchasing from reputable sources.

Are Crest Whitening Strips Safe?

Crest Whitening Strips are generally considered safe when used as directed. The American Dental Association (ADA) has even awarded some Crest products its Seal of Acceptance, signifying that they meet safety and efficacy standards for teeth whitening.

However, consider these points:

Tooth Sensitivity:

Some users may experience temporary tooth sensitivity after using the Strips, especially if the strips contain a higher concentration of peroxide. Crest offers products designed specifically for sensitive teeth, which may be a better option for those prone to discomfort.

Gum Irritation:

In some cases, the whitening gel can come into contact with the gums, causing irritation. This can be avoided by ensuring that the strips are applied properly and don’t overlap onto the gumline.

Overuse:

Using whitening strips too frequently or leaving them on for too long can lead to enamel damage or increased sensitivity. It’s important to follow the recommended usage instructions and take breaks between whitening cycles.

For people with existing dental conditions, such as cavities or gum disease, it’s advisable to consult with a dentist before using any whitening products.

How Effective Are Crest Whitening Strips?

The effectiveness of Crest Whitening Strips varies depending on the product and the severity of the stains being treated. Most users report noticeable whitening after a few uses, with full results appearing after the recommended treatment period, typically between 7 to 14 days.

Crest’s higher-end products, such as the Professional Effects or Glamorous White lines, offer more dramatic results, with some users seeing significant improvements in the brightness of their teeth. These strips are particularly effective at removing surface stains caused by coffee, tea, wine, and smoking, but they may be less effective at treating deep, intrinsic stains caused by factors like aging or certain medications.

While Crest Whitening Strips can deliver impressive results, they are not a permanent solution. Over time, stains can reappear due to lifestyle habits, necessitating periodic touch-up treatments.

How to Use Crest Whitening Strips for Best Results

For the best results, it’s important to use Crest Whitening Strips correctly and consistently. Here are some tips to maximize their effectiveness:

Brush and Floss Beforehand: Clean teeth allow the whitening gel to adhere more effectively to the enamel. However, wait about 30 minutes after brushing before applying the strips to avoid sensitivity.

Apply Strips Carefully: Make sure the strips are aligned with your teeth and pressed down firmly so that the gel comes into contact with the entire surface of the tooth. Avoid touching the gumline to prevent irritation.

Follow the Recommended Time: Leave the strips on for the instructed amount of time. Overusing the strips won’t result in faster whitening and may cause damage to your enamel.

Avoid Staining Foods and Drinks: During the whitening process, avoid consuming foods and beverages that can stain your teeth, such as coffee, tea, red wine, and tobacco. This will help preserve the effects of the treatment.

Stay Consistent: Use the strips daily as directed until you’ve completed the full treatment cycle. Inconsistent use can result in uneven whitening or delayed results.

Crest Whitening Strips vs. Other Whitening Methods

When compared to other whitening methods, they offer a balance of convenience, affordability, and effectiveness. Here’s how they stack up:

Professional Whitening:

In-office whitening treatments performed by a dentist tend to deliver faster and more dramatic results, but they are significantly more expensive. Professional treatments often use higher concentrations of peroxide, which is not available in over-the-counter products.

Whitening Toothpaste:

Whitening toothpaste can help maintain the results of a whitening treatment but is generally less effective at removing deep stains. It works best for surface stains and is often used in conjunction with other whitening methods.

Whitening Trays and Gels:

These at-home kits often contain similar concentrations of peroxide to Crest Whitening Strips but require the use of custom or semi-custom trays. While effective, trays can be messier and less convenient than strips.

Ultimately, Crest Whitening Strips are a great option for people looking for a relatively affordable and effective way to whiten their teeth at home, without the need for messy trays or expensive dentist visits.

Whitening Strips and Tooth Sensitivity: Managing Discomfort

Tooth sensitivity is a common side effect of using whitening strips, especially those with higher peroxide concentrations. If you’re prone to sensitivity, here are a few ways to minimize discomfort:

Use a Toothpaste for Sensitive Teeth: Toothpaste formulated for sensitive teeth can help strengthen enamel and reduce discomfort both during and after the whitening process.

Limit Whitening Sessions: If you experience sensitivity, try spacing out your whitening sessions or using the strips every other day instead of daily.

Choose a Gentle Formula: Crest offers products like the 3D Whitestrips Gentle Routine, which are designed for sensitive teeth and provide gradual whitening with less irritation.

Maintaining Results After Whitening

Once you’ve achieved your desired results, it’s important to maintain your newly whitened smile. Here are some tips for keeping your teeth white:

Brush and Floss Regularly: Good oral hygiene is key to preventing the buildup of stains. Brush twice daily and floss daily to keep your teeth clean and free from plaque and food particles.

Use a Whitening Toothpaste: Whitening toothpaste can help maintain the brightness of your teeth by removing surface stains.

Avoid Staining Foods and Drinks: As mentioned earlier, reducing your intake of coffee, tea, red wine, and other staining substances can help prolong your whitening results.

Touch-Up Treatments: Periodic touch-up treatments with Crest Whitening Strips can help maintain your results, especially if you notice stains reappearing over time.
