SHOULD I TRY WHITENING?
Not everyone’s teeth are suitable for whitening. For many people it poses no serious risk if done correctly. But if you choose the wrong treatment or it is applied incorrectly, then some damage can occur. Potential problems can include reduction of enamel strength, inflamed or blistered gums and tooth sensitivity. Crowns and fillings will not change colour, so you could end up with multi-coloured teeth.
See your dentist first who will check your suitability for whitening by looking at things like enamel thickness, receding gums, existing sensitivity, tooth decay, restorations such as fillings, crowns and veneers, and any other oral diseases.
The results of whitening can range depending on the cause of the discolouration. The reality is most people will achieve a one- or two-shade change but many will see no change at all.
