The One Click Smile system is designed to be quick, effective and unobtrusive. But to maximise the effectiveness of the results, you can follow some simple tips. Certain foods are more likely to stain and colour your teeth. Avoiding them for a short period after your treatment can increase the amount of time that it will last. Foods like tea, coffee, soft drinks, red wine, berries and curries all contain things that can stain your teeth. Simply avoid them for 48-72 hours after your treatment for the best results before resuming your usual diet. Of course, if you can’t avoid these things, then it is advisable to sip water after consuming them and brush your teeth as soon as is practicable afterwards.
