Crest 3D Gentle Whitestrips Whitening Kit for Sensitive Teeth

Why do we choose it?: Unlike other strips, Crest 3D Whitestrips do not cause pain, sensitivity, or stinging during and after use. These strips work quickly; in fact, we noted significant improvement after removing the first strip and expect to see better results in the future. Moreover, the strips are easy to use and store and integrate easily into the daily oral care routine. The strips need to be applied for 30 minutes daily. 

Opalescence Go Teeth Whitening Trays

Product specifications

Category: Trays

Price: 73.99$ at ebay

Active ingredients: Hydrogen peroxide (15%) 

Our rating

Comfort: 2.5/ 5

Convenience: 4/ 5

Value: 5/ 5

Effectiveness: 4.5/ 5     

User rating: 4.9/ 5 (based on only 16 reviews)

Pros: Easy to insert and work quickly.

Cons: Bit expensive, high strengths cause sensitivity.

Opalescence Go Teeth Whitening Trays

Why do we choose it?: These pre-filled whitening trays are the least messy and easiest-to-use whitening trays tested by us. Two trays are applied simultaneously, and the outer coloured tray is removed while the inner tray containing the whitening gel is kept in place for 15 minutes. We note somewhat discomforting yet bearable pain while applying the upper tray. The trays ensure bright and shining teeth after use for the recommended duration of just 15 minutes. It is discomforting, yet worth it. The users can adjust strength as desired.

iSmile LED Whitening Kit

Product specifications

Category: Gel

Price: 55£ at Amazon UK

Active ingredients: Carbamide peroxide (35%)  

Our rating

Comfort: 4/ 5

Convenience: 4/ 5

Value: 5/ 5

Effectiveness: 5/ 5     

User rating: 4.1/ 5

Pros:  High value for money, fast action and less messy to apply

Cons: Uncomfortable on gums

iSmile LED Whitening Kit

Why do we choose it?: The iSmile products are made of natural ingredients, e.g., chamomile flower extract, pomegranate and aloe leaf. Its natural and refreshing taste leaves the smile enhanced, and breath refreshed. Our testing found that the rapid 7-day application for 10 minutes daily is efficient. The effectiveness outweighs the slight discomfort experienced during the whitening process.

Spotlight Oral Care Teeth Whitening Strips

Product specifications

Category: Strips

Price: £27.30 at Amazon UK

Active ingredients:   Hydrogen peroxide (0.01%)

Our rating

Comfort: 5/ 5

Convenience: 4/ 5

Value: 4.7/ 5

Effectiveness: 5/ 5    

User rating: 3.9/ 4

Pros:  Good for sensitive teeth, fits comfortably and has a comfortable carrying case

Cons: Bit longer application time of 60 minutes

Spotlight Oral Care Teeth Whitening Strips

Why do we choose it?: The Spotlight Oral Care strips are an excellent blend of gentle formulation and comfort. Our testing found that the strips fitted quite comfortably and adhered tightly to the back and front of the teeth. The so-called “vacuum-sealed” effect created by the tight adhesion makes the full hour of wearing less comfortable. These strips work very quickly and produce visible results within a few days. A tester with sensitive teeth reported these strips as comfortable for sensitive teeth. Additionally, the packing has vitamin E oil for post-treatment application and a convenient travel pouch.

Lumineux Oral Essentials Whitening Strips

Product specifications

Category: Strips

Price: £37.30 at Amazon UK (42 strips, 21 treatments)

Active ingredients: Peroxide free formula

Our rating

Comfort: 4.5/ 5

Convenience: 4.5/ 5

Value: 5/ 5

Effectiveness: 5/ 5     

User rating: 4.2/ 5

Pros: Excellent results within three days, allow talk while wearing

Cons: Leave a film that persists unless brushed and covers only the visible part of the teeth.

Lumineux Oral Essentials Whitening Strips

Why do we choose it?: These strips are the best choice for people who prefer natural ingredients over chemical-based strips. Despite the lack of chemicals, these strips are highly effective for the job. These strips don’t interfere with the conversation and leave a refreshing taste. Our testing noted a two-shade improvement in whitening with just three days of regular use. Moreover, the lack of chemicals makes it highly friendly for sensitive teeth.

Auraglow LED Whitening Kit

Product specifications

Category: Light kit

Price: 48

Active ingredients:   

Our rating

Comfort: 4.5/ 5

Convenience: 3.3/ 5

Value: 4.5/ 5

Effectiveness: 5/ 5    

User rating: 5/ 5

Pros: Easy to use, comfortable and highly effective

Cons: No battery indicator available, somewhat awkward

Auraglow LED Whitening Kit

Why do we choose it?: Albeit a low efficacy, the results are still excellent with just two weeks of regular use. Keeping a whitening LED tray in the mouth for 30 minutes is awkward. Our tester found the lack of low battery notification very frustrating, but this drawback is manageable given that one recharge is enough for daily use. Whitening results are excellent, given the price tag and lack of discomfort and pain during the process.

Auraglow Whitening Pen

Product specifications

Category: Pen   

Price: 22$

Active ingredients: Carbamide peroxide (35%)

Our rating

Comfort: 4.5/ 5

Convenience: 5/ 5

Value: 3.5/ 5

Effectiveness: 3.2/ 5

User rating: 4/ 5

Pros: Convenient small pen, no discomfort, short application time of just 1-2 minutes and easy whitening on the go

Cons:  Moderate results

Auraglow Whitening Pen

Why do we choose it?: It offers excellent convenience, albeit at the cost of whitening efficacy. Our testing found that it causes only one shade of whitening. However, it is still a reasonable choice when coupled with a low price tag, a painless process, and the ability to use it on the go. The ease of application and option to take it everywhere make it a trustworthy partner for a nighttime brushing routine.

Price: £16.70 (at ebay)

Active ingredients: Peroxide free formula

Our rating

Comfort: 4.5/ 5

Convenience: 5/ 5

Value: 4/ 5

Effectiveness: 3.5/ 5     

User rating: 3/ 5

Pros:  Good sensitivity, convenience, cost-effective and instant results 

Cons: limited effectiveness, poor taste and texture of the paste

  Laser Glow Toothpaste Colour Corrector

Why do we choose it?: The unique formula of Laser Glow toothpaste, gentle whitening effects, and ease of use make it the best whitening paste. Despite the lack of chemical ingredients, its unique formula reduces the discolouration and yellowing of the teeth, albeit only for the superficial ones. The ease of application makes it very easy to incorporate it into daily oral health care routine.

Cali White Teeth Whitening Kit

Product specifications

Category: Whitening gel

Price: 28.61£ (at ebay)

User rating: 3.9/ 5

Pros: Good whitening results, convenient application and cost-effective

Cali White Teeth Whitening Kit

Why do we choose it?: The Cali White Teeth Whitening Kit provides a convenient option to achieve a brighter smile at home. The gel penetrates well into the crevices between the teeth to deliver a deep and uniform cleaning. Including a blue LED light with a timer makes it highly effective. A stylish topical case and universal comfort tray are additional plus points. The good news for vegans is that it is a vegetarian product and cruelty-free. It is free from gluten, dairy, GMPs, phthalates, parabens and sulphates, enhancing its acceptability and safety.
