Can yellow teeth become white? A guide to Zoom teeth whitening in Harley Street

One of the most well known and most popular of all cosmetic procedures that we can offer our patients at Harley Street is dental whitening.


Once a procedure that could cause high levels of discomfort due to the chemicals which were used, whitening has become more comfortable and affordable for many people who may feel a bit of embarrassment related to the shade of their teeth.

And while you may have concerns that whitening options which use gels may set off your dental sensitivity, our team at Harley Street only use the gentlest gels, which will help you get the whiter smile you want, without the discomfort.

When you come to our team for teeth whitening Harley Street, we can offer you 2 different types of whitening gels. The first is Zoom, which utilises custom-fitted plastic trays and at-home treatments to whiten your smile. The second is Enlighten, which also uses trays and an at-home based procedure to get your teeth whiter in as little as 2 weeks! However, our team will help you choose the correct treatment for you.

In this article about teeth whitening Harley Street, our team will answer 5 frequently asked questions about the Zoom whitening system.

Can my yellow teeth really become whiter?

Yes, of course they can.

But depending on the underlying cause of the discolouration and how yellow your teeth are, your teeth whitening Harley Street may take slightly longer. Using Zoom, your teeth can be lightened up to 16 shades in 2 weeks, but the level of whiteness obtained will depend greatly on the initial shade of your teeth.

How does it work?

Our team will paint an oxidising gel onto the surface of your teeth and then, using a specialist light, this will help to break down stubborn stains.

Once you are home, you will be given a set of custom-fitted trays to place a milder whitening gel into, which will need to be worn for 14 days, preferably overnight.

My teeth are discoloured due to medication; can this treatment still work?

Yes, it can, it may just take multiple whitening treatments.

If you feel that the Zoom whitening system is not working as well as you want it to, talk to our team about alternative whitening treatments that we can offer you.

How many shades can my teeth be lightened by?

As mentioned earlier, Zoom whitening can make your teeth up to 16 shades whiter in 14 days.

But this may or may not give you the final shade that you were looking for, and so, additional treatments may be required.

How long will the effects last?

The results of Zoom whitening can last up to a year, but this may be shortened if you smoke or regularly consume acidic products like oranges, sodas, red wine or drink black coffee.

Luckily, our team can provide you with a top-up gel, designed to keep your teeth as white as possible for an extended period of time. What’s not to like about that?
