Cleaning your teeth may sound like a necessity rather than an indulgence - but then again, it really depends what kind of toothpaste you use. A brand new treatment at Toothplace, the UK's first walk-in dental hygiene bar, uses real diamonds to produce a dazzling, Hollywood-style smile.

The High Gloss Diamond Polish is infused with diamond particles to give your teeth that all-important instant sparkle. But first your specially trained hygienist will tackle those pesky tough stains and debris - by getting to work on surface plaque using a state-of-the-art Ultra Sonic Scaler. Visible calculus is quickly removed - then a jet wash spray combines water, air and powder to target stubborn stains and produce a smooth, clear finish.

And to top off your new smile, your gnashers are given the once-over with the diamond-based polish. The result? Your teeth will be restored to their natural gleam and whiteness. Treatment lasts for 30 minutes and costs £80.

However, if you really want to indulge yourself - and ensure you have super-fresh breath - you could splash out £150 on a celebrity-style Breath Freshening Treatment. Your breath is analysed using the latest technology from California - a device called the Halimeter. This measures 'volatile sulphur compound' concentrations - otherwise known as 'the stuff that makes breath smelly'!

You'll then be given a specially tailored treatment, as well as a homecare programme and follow-up appointment, to help keep your breath naturally fresh forever. Now that's definitely something to smile about, isn't it?
