Hi Andrew. I’m 47 and have always had natural cream toned teeth. But, I’m now feeling quite embarrassed whenever I smile as they are now rather yellow. My dentist and my son’s orthodontist technician think that I may have antibiotic staining. (I did have various antibiotics in my teens for acne treatment) and that bleaching by the orthodontist may not have any effect or leave me with lines of discolouration.
Would laser whitening be more effective? Thank you.
