It is worthwhile seeking out the guidance of dental healthcare professionals when considering teeth whitening, as there are risks associated with making poor decisions.
While many internet and pharmacy-bought kits may be much cheaper than going to a treatment centre, the end result is sufficiently different to warrant paying more.
According to the Daily Mirror's Miriam Stoppard, professionals will apply a special teeth whitening gel and explain exactly what to do in the weeks following an appointment.
In her view, it is definitely worthwhile spending more money, as the treatment will be done with the patient's teeth in mind, rather than simply being a standard application from a box.
Ms Stoppard added: "Some online treatments, supplied from abroad (don't be fooled by a co.uk address!) may contain illegally high concentrations of bleach that may permanently damage the tooth enamel."
Last month, BBC News reported that the General Dental Council called for new legislation regulating who is able to carry out tooth whitening operations in the UK.
