Teeth whitening in London: things to know before you go

Teeth whitening has gone from niche luxury to a mainstream essential in a matter of years. More people are cranking their smiles up a notch – and teeth whitening is now a billion-dollar industry. All the most common questions you have about teeth whitening are answered here.

Does teeth whitening really work?

Teeth whitening is proven to deliver a brighter smile. Teeth naturally discolour with age and stain as part of your daily London life – be it a coffee-to-go every day, a cheeky cigarette on your break, or glass of red wine in the evening after a hard day’s work. Many people feel more confident with whiter teeth. Teeth whitening treatment is a speedy process that works in several ways:

  • Intrinsic teeth whitening - brightening the colour of the dentin inside your teeth
  • Extrinsic teeth whitening – whitening the enamel of your teeth

When having your teeth whitened by a dentist, you’ll find they tend to use a concentrated hydrogen peroxide formula to your teeth using a mouth guard. In London, laser teeth whitening is becoming popular and only takes an hour. However, take note that teeth whitening will not work on dentures, veneers, fillings or crowns.

Does teeth whitening cause any dental problems?

Teeth whitening is a completely safe dental treatment, but it can cause dental problems when the treatment is carried out too much or incorrectly.

For example, over-bleaching can increase the sensitivity of your teeth and wear down your enamel to dangerously low levels – making tucking into delicious ice creams and sipping on cold drinks painful.

Teeth whitening kits can also cause problems. The mouth guards they typically provide are generic in size, increasing the risk of the hydrogen peroxide gel leaking out, and potentially causing irritation in your mouth.

In London, there are many prestigious teeth whitening clinics that carry out this process – and other types of dental treatments – quickly and safely.

How much can I whiten my teeth and how long does it last?

Teeth whitening is never a permanent solution, as your teeth will continuously change colour as you get older. Over time, enamel thins and the yellow from your dentin shines through. Your lifestyle may also affect the amount of staining present on the exterior of your teeth.

Using whitening toothpaste daily removes superficial stains and will whiten your teeth a little. Bleaching is the most effective teeth whitening treatment, lasting anywhere between six months and three years. However, it shouldn’t be repeated as often.

Where can I get the best teeth whitening services?

Living in a city as large as London gives you so many options for teeth whitening. Whether you’re looking at booking in for a professional teeth whitening service, or you want to apply your own teeth whitening treatment at home, you can find deals on teeth whitening services, products and kits all over the city.

A stone’s throw away from Leicester Square underground station, Covent Garden Aesthetic Clinic is one of the highest-rated clinics providing Zoom laser teeth whitening treatment. Closer to the Barbican you can find Smileright Dencare – another top-rated clinic with a prestigious reputation in London.
