Want to undertake teeth whitening? A guide to the procedure from Harley Street Dental Clinic

When you brush your teeth each day, do you feel that they look white enough afterwards?


If you are like most dental patients, then the answer is no!

With busy daily schedules and highly acidic foods and drinks now commonplace, it is no surprise that many people have a yellow tint to their teeth. Even with brushing and whitening toothpaste, some stains are stubborn and will require a professional to remove them correctly.

Whitening teeth is one of our most popular procedures at Harley Street Dental Clinic and should you want to banish yellow tints for good, come to us!

Our team can offer you 2 systems for teeth whitening Harley Street, and we will choose the one that is most suited to you based on the causes and severity of your staining. We can offer both Zoom and Enlighten, which combine at-home procedures with in-surgery whitening to give your teeth an ice-white smile you won’t be able to stop showing off to all around you!

But what exactly is the process for teeth whitening Harley Street? Read on to find out!


Before we begin your teeth whitening Harley Street, our team will need to examine the level of staining to assess the best system for you.

As mentioned earlier, highly acidic foods and drinks can cause staining, but so can medications, smoking and even genetics. Also, we will need to assess your teeth for eroded enamel and exposed dentine. During your assessment, we will also take moulds of your teeth, so you can have a custom-fitted device for at-home whitening.

First session

During your first tooth whitening session, with both Zoom or Enlighten, we will gently paint an oxidising gel onto your teeth and will place a UV lamp to begin removing the stains.

Depending on the severity of the staining, the time that this takes may vary and once it is over, we will provide you with an oxidising gel to wear at home with your customised mouthpiece.

At home whitening

For the next 14 days, you will need to apply the oxidizing gel we provided to the inside of the mouthguard.

Wearing it to bed, it will gently remove the more stubborn stains that are present on your teeth. For the best results, you should also try to refrain from drinking coffee, wine or sodas to prevent stains from reforming on the enamel.

If you feel that there is an issue with the process or if your mouthpiece feels loose, contact us.

Second session

On your second visit, we will once again apply an oxidising gel to your teeth and use UV light to remove the remaining stains.

Regardless of whether our team has used Zoom or Enlighten, your teeth will now be up to 16 shades whiter. Be aware that, as with most gel-based whitening, there is going to be a period of sensitivity, where your teeth may react to hot or cold liquids and food. Given time, this should settle – if it doesn’t, contact us!
