The Teeth Whitening process

First appointment

At the initial assessment, your dentist will assess your suitability for teeth whitening and discuss any points that need further consideration.

By taking the current shade of your teeth, the dentist can give you a clear idea of the expected results you can achieve.

If you are happy to commence with the whitening treatment, the dentist will take impressions of your teeth. These impressions will be sent to a dental laboratory and are used to make the custom-made whitening trays that you will later use to whiten your teeth. It usually takes 2 weeks for the whitening trays to come back.

Second appointment

The dentist will first check the custom-made trays fit your teeth correctly. You will then be advised on how to safely carry out the whitening treatment. Your dentist will advise you on what to do before placing the trays in your mouth.  And also how to adequately place the gel in the whitening trays.

What are the recommended wear times?

When using the Zoom DayWhite system, recommended wear time is 30mins twice daily. Optimal results will be achieved after 1-2 weeks.

With the Zoom NiteWhite system, recommended wear time is 4-6 hours or overnight. For optimal results will be achieved after 2-3 weeks.

General Aftercare

It is important to maintain routine check-ups with your dentist, normally twice a year. This is to ensure your teeth and gums remain healthy and strong.

Brush twice daily and floss to effectively remove the plaque on your teeth.

We recommend using normal toothpastes after completing treatment. There is no need to use whitening toothpastes. 

Are teeth whitening kits safe?


Teeth whitening should always be carried out under the supervision of a dental professional. When conducted properly, it is a very safe procedure with predictable results. During treatment, your teeth can become temporarily sensitive to hot and cold. The Zoom whitening gel has potassium nitrate integrated into the gel to reduce sensitivity during treatment. Potassium nitrate is the same ingredient used in many desensitising toothpastes. 

Check with dental professional if using the kit is suitable for you.

Teeth Whitening FAQs

What is the difference between teeth whitening and airflow treatments?

Airpolish is an effective way to remove the external staining on your teeth as a result of your diet and lifestyle habits. Removal of external staining on enamel will bring back the tooth's natural shade but does not alter the shade of the enamel. Professional teeth whitening will change the colour of the enamel layer of teeth, resulting in a whiter brighter smile.

How often can I whiten my teeth?

There is no specific time limit with regard to bleaching your teeth. Most patients are happy with whitening results after 2-3 weeks of use. This process can be safely repeated after a few months. In very resistant circumstances, bleaching would need to be carried out for several months before the desired result is achieved. In such scenarios we would advise close monitoring of treatment with your dentist.

How long does it take to whiten teeth?

Length of treatment varies from person to person. Almost all patients will get whiter teeth, however, some take longer than others depending on their start shade and type of staining. The type of staining that responds best to whitening treatment are staining caused by foods/drinks, tetracycline medication staining, tobacco and non-vital teeth. Duration of treatment is also dependent on the shade of tooth colour you would like to achieve, as a whiter shade will take longer to achieve. Most of our patient will whiten their teeth for a period of 2 to 3 weeks to achieve their desired tooth colour.

Is the whitening effect permanent?

Of all the methods that can whiten your teeth, the home whitening treatment with bleaching gel is the most effective and long-lasting treatment. However, the change in shade will vary according to your habits. The whitening effect will last longer if you avoid/reduce smoking, tea, coffee and other dark coloured foods and drinks.

What is the price to professionally whiten my teeth?

At Wandsworth Dental Centre, we offer some of the best prices to whiten your teeth. The price is £300 for Home Tooth Whitening bespoke treatment kit. And £20 per whitening syringe.

Does the whitening gel expire?

Yes. Note the expiry date is present on the outer packaging and on the individual bleaching syringes.

What should I avoid during whitening treatment?

During whitening treatment, your teeth are more porous and therefore more suseptible to staining. For this reason, to achieve the best possible whitening results, we would advise to cut down or eliminate smoking, dark staining drinks like red wine, coffee, tea and fizzy drinks. Also avoid dark staingin foods containing tomato sauces, soy sauce, chocolate and dark marinades. Note that following the above advice after completing teeth whitening will prolong the whitening effect on your teeth.

What if I'm not happy with the results?

The first thing to do is to contact the dental practice and discuss your results with a dental professional. The solution could be as simple as changing the whitening get or other options can be discussed with your dentist to give you your desired result.

What if I experience gum discomfort or tooth sensitivity?

It is very normal to experience some tooth sensitivity during treatment. This is usually mild and temporary. After completing treatment, these effects will fade away. If the whitening causes significant discomfort and sensitivity, reduce the wear time or carry out treatment every other day. Please note when you reduce your wear time, it will normally take longer for you to achieve the desired whitening effect.

What is the best teeth whitening system to use?

At Wandsworth Dental Centre, we believe we are giving our patients the best whitening product with the Philips Zoom home whitening kit. The whitening process is effective, with consistent and predictable results.

What happens to the whitening gel when it is in my mouth?

Hydrogen peroxide, which is the active ingredient in whitening gels, breaks down slowly over a period of a few hours into water and oxygen gas which are safe.

How should I store the whitening gel?

The gel should be stored in a cool dry place like a fridge. Avoid leaving in warm places and under direct sunlight. Do not freeze
