The Teeth Whitening Process

At Smile Aesthetics, we understand that every smile is unique.

That’s why we offer a teeth whitening treatment that is unique to you.

Not all teeth require the same level of whitening, which is why we create a bespoke treatment plan to reach your desired shade.

The process begins with a custom consultation.

We’ll assess the current shade of your teeth and decide which shade you are looking to achieve.

We will work with you to understand your goals and create a treatment plan that is tailored to you.

After your consultation, custom trays are moulded to your teeth for the perfect fit.

These trays are used to apply the whitening gel evenly across your teeth.

We’ll provide you with a course of Boutique Whitening gel along with easy instructions to follow at home.

The entire process is simple, convenient and effective. Perfect for busy people who want to achieve great results without spending hours in the dentist’s chair.

If you are interested in teeth whitening or would like to learn more about our services, please contact us today.

We would be more than happy to answer any of your queries regarding the teeth whitening process.

Professional Teeth Whitening from a Dentist is the only safe, legal, effective and long-lasting method of achieving a whiter, brighter smile.

Here at Smile Aesthetics we use Boutique Whitening, which is a quality, prescription-strength teeth whitening system that delivers superior results.

What Causes Tooth Discolouration?

There are plenty of lifestyle choices that can cause discolouration of teeth over time, but you may not be aware that the whiteness of your teeth can also be influenced by genetics, ageing and your general health and well-being.

Discolouration of the tooth occurs on the hard outer layer, known as the enamel.

Some people are born with slightly discoloured teeth while others develop discolouration with age. 

Yellowing of the teeth and staining can also result from the food and drink you consume and the lifestyle choices you make.

Some of the key contributors to teeth staining include food and drinks, especially those that include high amounts of tannins.

These include tea, coffee, red wine, and cola.

Smoking tobacco products will also have a significant effect on the colour of your teeth, as the nicotine in these products can lead to deep-set staining.

In order to restore a clean white appearance, professional treatment is required.

Whilst there are plenty of commercially available products, none of these are suitable for long-lasting and safe teeth whitening.

Instead, they can cause irreparable damage to the enamel and gum, leaving your teeth looking worse than they were.

At Smile Aesthetics, our teeth whitening is professionally approved and can only be supplied by a certified dental practice, contact us today to find out more.

Before & After


Professional Suppliers of Boutique Whitening

Here at Smile Aesthetics, we are committed to providing the safest and most effective professional teeth whitening to our clients.

Our take-home teeth whitening product, Boutique Whitening, offers just that.

This premium-quality product guarantees effective and controlled results, enabling clients to achieve the smile that they desire. 

Our take-home whitening kits include everything you need to reach the shade you are looking for.

Your kit contains custom-made trays and syringes containing the specialist whitening gel.

Carbamide peroxide gel is a hydrogen peroxide compound that is professionally approved for teeth whitening and offers reliable results.

Whilst creating your treatment plan, we’ll discuss the appropriate strength of whitening gel for the number of hours you wish to wear your trays.

The kit is designed to be worn anywhere from a couple of hours to overnight.

Over a number of days and weeks, you’ll start to notice a gradual build in the whiteness of your teeth.

Depending on your starting shade, it will take between one and two weeks to reach your desired shade of whiteness.

The effects of teeth whitening are permanent, however the shade will very slightly darken over an extended period of time.

Depending on your lifestyle choices and consumption of staining food and drinks, your teeth might darken more quickly.

Top-up whitening sessions at home are usually recommended every 6-12 months to ensure that your perfect smile is maintained. 


There are options for in-surgery whitening however this is limited due to the restrictions on the concentration of gel allowed in the UK.

This means that in-surgery whitening is much less effective and value for money compared to at-home whitening.

It is also rarely provided as a stand-alone treatment, mainly alongside at-home whitening.

We go through all the instructions with you as well as ensuring your whitening trays fit.

Using your trays at home, you will regularly apply the gel for either 1-2 hours or overnight depending on the preferred system.

Results can start to be seen after the first treatment but the ideal treatment length is 1-2 weeks.

It’s as simple as that!

On your first appointment we will check to see if you are suitable for whitening and take impressions/moulds of your teeth, this is sent to our lab to make your custom-fit trays.

In 1-2 weeks once your trays arrive we will bring you back, make sure they fit, give you your Boutique Whitening System and you’re ready to get started!

Home whitening allows you to achieve excellent results in the comfort of your own home.

The whitening gel itself contains Hydrogen Peroxide at a safe, prescription-strength concentration.

This is placed and held against the teeth by custom-fitting whitening trays/mouth-guards, allowing the gel to stay in contact with the teeth without spilling out onto the gums.

The Hydrogen Peroxide safely penetrates the enamel, breaking down the molecules that stain teeth, making the teeth appear whiter and brighter.

Professional teeth whitening is a very low risk procedure, however some people may experience some temporary sensitivity during treatment.

This can be minimised with a good sensitive toothpaste (provided) and by decreasing the frequency of applications.

Teeth whitening only works on natural teeth (not crowns/bridges/implants and fillings).

Results last 6-12 months but top-up syringes can be bought separately.

A professional clean is usually recommended before whitening to remove surface stains & buildup to maximise the effect of the whitening (extra charge, see Platinum Deal for combination of both).
