What is Tooth Whitening?

Tooth whitening is almost always the safest and least invasive way to improve the appearance of your teeth. It works by removing staining within the tooth structure from the outside. You can complete the treatment at home using small whitening trays filled with whitening gel. 98% of patients are satisfied with the results in 3-6 weeks.

Frequently asked questions

  • Will it damage my teeth?

    Whitening at home for 3 weeks does the same damage to enamel as drinking 1 can of coke. There is no evidence that it has any effect on the nerves or root surfaces of teeth.

  • Is it safe for the rest of my body?

    Tens of millions of people have had this form of treatment since its introduction in 1998 and there has been no evidence of any link to any other diseases such as cancer in the rest of the body.

  • My teeth are generally sensitive – will they be more sensitive during whitening?

    50% of people have mild sensitivity during whitening, 10% have moderate sensitivity, 4% have severe sensitivity. Normally more severe sensitivity occurs when patients have recession of their gums, which exposes the roots of their teeth, or when people use too much or too strong whitening gel. Very few people find their teeth are so sensitive that they need to stop whitening and in almost all cases sensitivity is transitory and settles down after treatment.

  • How white will my teeth go?

    If you have never whitened before, the average response is 8 shades lighter on a dental shade guide or to shade A1 (we can show you what this means on a shade guide).

  • How fast will they whiten?

    The tips of your teeth will whiten first, then the bases will catch up. Most people get the maximum whiteness after 3-6 weeks.

  • Does stronger gel make them whiter?

    No. It will cause whitening to occur quicker, but it will also cause more sensitivity.

  • Will I be satisfied with the change?

    Studies have shown that 98% of people are satisfied with results. When discolouration is severe, such as tetracycline staining, this drops to 86%.

  • How long will the change last?

    Your teeth will look their best for 2-3 years. After 18 months 25% of the colour change will be lost. After 3 years 50% of the colour change will be lost. It is at this stage most people decide to whiten again.

  • How often will I need to re-whiten?

    Normally people tend to re-whiten for about a week every 2 years. We will be happy to sell you further whitening gel once we have checked that your mouth is still healthy.

  • Do I have to avoid eating coloured foods?

    No. Coloured foods will not affect the process, however be aware that some mouthwashes (particularly chlorhexidine), some drinks (such as tea, coffee, red wine, and coke), and some foods (curry, beetroot, and colourings), will cause your teeth to stain again.

  • Will my fillings or crowns also whiten?

    No, only natural teeth. It is likely that restorations will need to be replaced if they do not match after whitening at further cost, which we can quote you for in advance.

  • Do I need to whiten one set at a time?

    No. The top and bottom teeth can be whitened at the same time.

  • Are whitening toothpastes an alternative?

    Whitening toothpaste can remove surface staining on teeth. If you drink a lot of tea, coffee, or red wine then it may help. It does not however penetrate the tooth to lighten it from the inside. Only professionally prescribed dental whitening gel is able to do this.

  • What about a Boots whitening kit?

    The only dental whitening gel able to lighten your teeth from the inside is a prescription medicine which cannot be on general sale. Any supermarket kits will not have sufficient amounts of the active ingredient to be effective.

  • Can I buy gel from the internet to use in the trays you have made?

    If the gel you are buying contains an active ingredient that will work safely, it’s sale is illegal other than by a dentist. This is because you need to be assessed to make sure treatment will be safe and that you are using the correct whitening gel. Any fake gels may at best do nothing to your teeth but some are very acidic and may harm your teeth.

  • I have whitening trays already. Can I just buy some more gel?

    It is a legal requirement that a dentist assesses you first before supplying whitening gel for both new and top up treatment. This is to make sure whitening will be safe and so that we can provide you with the correct whitening gel. Please bring your trays in and we can check you are suitable and that the trays still fit.

  • I am worried that my teeth are sensitive after whitening?

    Most people do experience sensitivity at the start. Don’t worry it will go away once whitening has finished. It may be worth trying alternative nights. Applying sensitive toothpaste to your teeth for 3 minutes before and after whitening can help. This can be purchased from reception.

  • I have whitened and white spots on my teeth seem to have gone even whiter?

    This is common but they will fade after treatment is completed.

  • My teeth have gone two colours?

    Often the tips of your teeth will whiten quicker than the bases due to the tooth thickness. Do not worry and keep whitening and the base of your teeth will catch up. Sometimes very white areas of your teeth can become whiter initially due to dehydration. Once you finish whitening this will fade.
