Best home teeth whitening kit: How to whiten teeth


Teeth are a common insecurity among Brits, with the rest of the world poking fun at our supposed crooked smiles. More than 80 percent of us are worried about how our teeth look in photos, and almost 30 percent won't smile with teeth in pictures. These feelings have an impact on our mental health and self-esteem. More than half of us feel pressure to have sparkling teeth to measure up to the smiles of celebs. Instead of opting for a full set of veneers, you can whiten your teeth at home. Express.co.uk chatted with Lucie Marchelot Shukla, Co-Founder of Instant Dentist & Straight Teeth Direct to find out how to whiten your teeth at home.

Why are my teeth yellow?

Dental enamel erosion

Lucie said: “Teeth are made of two layers: the enamel which is more white, and the dentine underneath which is more yellow/cream in colour.

“When teeth have healthy thick enamel, they look whiter.

“However, dental enamel erosion causes the dentine underneath to become more exposed, making the teeth appear more yellow.

“This is the main reason for healthy teeth to become yellow as part of the normal ageing process.

“Enamel gets eroded every day, mainly through acidic food and drinks.

“This is why Straight Teeth Direct has partnered with Regenerate Enamel Science™, as it’s not possible for the body to regenerate enamel alone.

“The revolutionary formula of this toothpaste helps to regenerate tooth enamel in the early stages of erosion by using the same mineral found in its composition.

Do at home whitening kits really work?

There is a whole range of options you can try to whiten your teeth, but you have to be careful.

Lucie said: “There are many different options out there and they are not all effective or adapted to your needs.

“Due to cosmetic regulations, there is a limit on the percentage of peroxide contained in products sold over the counter.

“This peroxide strength could improve the tooth colour by maximum one or two tooth shades, but if you have thin enamel it will have a limited effect.

“There is a big trend with the kits that include LED light in them which we see all over Instagram and social media.

“While it may look cool in selfies, the theory behind the LEDs emitted speeding up whitening when it comes into contact with peroxide is debatable.”

Lucie added: “Research shows that ‘the use of light activator sources with bleaching treatment of vital teeth does not increase the efficacy of bleaching or accelerate the bleaching'.

“This means if the blue light whitening kit contains a peroxide gel, the colour of your teeth will improve as a result of that, but the light has nothing to do with this process.”

Which at-home teeth whitening kits are the best?

Lucie said: “The most effective solution to whiten teeth is through custom-fitted teeth whitening trays that will allow the product to distribute evenly around your teeth and over a sufficient duration to have an effect and whiten throughout the tooth.

“These would generally be worn overnight over a period of 7 to 14 days in combination with desensitising gel.

“This whitening solution should be supplied by a dentist following a screening of your teeth and gums and should not be used in the presence of gum disease or tooth decay, hence the importance to do this following an assessment by a dentist.

“The active ingredient is hydrogen peroxide that penetrates deep into the tooth and brightens the tooth from inside out.”

She added: “As an alternative, you could consider products that boost and strengthen your enamel such as enamel targeted toothpaste or fluoride trays provided by your dentist.
“The Regenerate™ Advanced Enamel serum kit combines the advanced enamel serum with an activator gel that when combined unleashes a concentrated boost of the formula, helping to reverse the early enamel erosion process.

“This approach is sure to improve the quality of your enamel and protect your teeth all together.”

She also recommended a simple two-step process to follow everyday to rid your teeth of stains.

She said: “Use a good electric toothbrush to clean away any surface staining with a whitening toothpaste that is gentle on the enamel such as special care enamel toothpaste.

“Follow up with an irrigator or water flosser to clean away stains between the teeth.

“This will mean your natural teeth are as stain free as possible.”

Can you whiten your teeth with natural products at home?

Lucie pointed out that acidic foods and drinks cause enamel erosion and turn your teeth yellow in the first place, so natural methods may worsen the situation.

She said: “Applying natural DIY potions on your teeth can potentially attack your enamel further and damage your teeth.

“Over the past years, charcoal powder has taken the internet by storm as an all-round beauty miracle in skin products, hair treatments and, you guessed it, teeth whitening.

“Charcoal powder is an abrasive that removes surface stains.

“It’s just a much coarser abrasive, so it’s more aggressive on the stains than regular whitening toothpaste.

“It can only remove stains at the expense of damaging your enamel, the intrinsic colour of the teeth won’t change.

“Baking soda is used in some toothpaste and can potentially help with surface staining but it won’t change the tooth colour.

“There isn’t scientific evidence to back the benefits of coconut oil in relation to teeth whitening.”
