The Potential Dangers of at Home Whitening Kits


A recent study found that 76% of people in the UK wanted to change something about their face or body, with the most desired treatment being cosmetic dentistry.

43% of UK respondents wanted to improve their teeth with whitening, veneers or Invisalign, with the main reason reported as being to improve their self-esteem and confidence.

For these reasons, at home whitening kits have increased in popularity… but are they safe and what are the dangers?

The active ingredient in most teeth whitening products is hydrogen peroxide, a substance that can be dangerous if not used correctly. Worryingly, many products sold online contain illegal amounts.

Potential Dangers Include:

– Chemical Burns
– Damage to Teeth Enamel
– Damage to Gums
– Mouth Infections
– Sensitivity

To be safe, it is always best to ask your dental practitioner who will be able recommend the best product for you to safely achieve fantastic results.

On the other hand there are numerous products available that claim to provide a sparkling smile but simply don’t work, and are a waste of time and money!

How to Avoid The Dangers of Home Whitening Kits

– Ask your dentist to recommend a suitable product for your teeth
– Check the bleach concentration and make sure it is no more than 10%
– Check online reviews
– Make sure the guards/strips fit teeth perfectly to avoid overexposure to the gums. Dentist provided home whitening kits usually include a special mould created from a impression of your teeth for a perfect fit.

When to Take Extra Care:

– If you have restorative work such as fillings: The materials used to carry out restorative work often don’t whiten well, meaning you could end up with an uneven and patchy result from whitening.
– If you are allergic to peroxide: Anyone with  allergies MUST consult their Dentist before beginning teeth whitening.
– If you have existing dental health issues: Individuals with existing problems such as cavities or thin enamel should also consult with a dental professional before using home teeth whitening kits.
– If you wear braces: Whitening strips and guards can not be used with braces, as only the surface of the tooth in contact with the product will be whitened.
– If you take any prescription drugs: Speak to your dentist before beginning treatment.
