Ask our dentist – all you need to know about whitening

In the era of selfies and social media, we all want to look our best. Often, that starts with teeth whitening, one of the most popular forms of cosmetic dentistry and a treatment that patients regularly ask about. So, we asked our lovely dentist, Dr Emily, to answer all of your burning questions about whitening treatment.

What does the process of teeth whitening treatment involve and how long before I can see results?

The first appointment will involve us taking accurate moulds of your teeth so your whitening trays can be made. At the second appointment we then fit the trays and take some time explaining exactly how to apply the gels at home and how to get the best results. A course of whitening lasts up to 2 weeks and you can normally start seeing gradual changes after the first couple of applications.

Why is it illegal for non-dental professionals to provide whitening treatment?

Only dental professionals are licensed to prescribe the strength of whitening gel that is needed for effective tooth whitening. It is extremely dangerous to have your teeth whitened by anyone that hasn’t been trained properly and can have serious consequences to both your gums and your teeth.

Will my teeth become sensitive?

The studies show there is about a 1 in 4 chance that your teeth may become sensitive during the treatment. The reason for this is because the action of the whitening gel makes the teeth more porous so the stains can leave the teeth. Don’t worry though, as soon as you stop the treatment the sensitivity will resolve.

Does whitening toothpaste work?

There are several whitening toothpastes on the market. They will not change the natural colour of your teeth but may be effective at removing the external staining.

How long does teeth whitening treatment last?

The effects of whitening can last up to three years, but this will vary from person to person. If you smoke and eat or drink products that stain your teeth, you will need to whiten your teeth more frequently.

I have crowns/veneers, can I still whiten my teeth?

Yes, however whitening will not change the colour of any crowns or fillings and if you have any of these at the front these may need to be changed after your whitening is complete so they can match the rest of the teeth.
