Celebrity teeth before and after veneers and whitening, from Cheryl to Katie Price

Celebrities are known for their love of tooth contouring, championing veneers and getting treatments that will whiten and brighten teeth, but what did their teeth look like before the transformation?

Luckily, we have some answers, as Dr Reena Wadia, Gum Specialist and Founder of RW Perio spoke to OK! about the secrets behind celebrities and their sparkly teeth.

Dr Reena told us veneers “need regular maintenance", while saying “everything has a lifespan,” when asked how long veneers last.

Attention was drawn to Connor Durman's teeth on Love Island last year as the reality star admitted to getting his teeth done in Thailand – which Dr Reena warned you need to be “very careful” about.

She said: “Dental tourism is on the increase and the public need to be very careful about this. Some of the ‘packages’ available abroad are enticing as treatment can be done quickly and cheaper than it would be here but you need to think about quality.

“Also if something goes wrong, it will be tricky to get that sorted with a dentist here if the treatment has been done abroad.”

And veneers are pricey, too, but Dr Reena says that “most places offer interest-free finance plans so that really helps. Fees vary massively depending on the procedure from £100-£3000.”

Championing veneers, Dr Deepak Aulak, the award-winning celebrity dentist and founder of the UK's first teledental platform Tooth Fairy also told us: "The great advancements of dental materials mean that veneers can be thinner than an acrylic nail - and sit neatly on top of teeth. The appeal to many of my celebrity clients is the speed in which they can be placed (usually within 2 weeks) and the many features that veneers can improve such as the shape, width and length of the teeth as well as the overall colour."

Dr Deepak added: "For many of my celebrity clients who are time-poor, veneers can be very quick, but I am now seeing a rise in many of my clients who are models and premiership footballers up-taking invisible straightening through my award-winning dental app. Discussing the negative aspects, Dr Deepak said: "The cons of veneers are that in some cases there is some tooth removal required, even if half a millimetre, but this is dependant on a case by case basis."
