hello doctor, i have this question. i’m a patient of LUPUS (SLE). have had it now for 5 years. n i have noticed a change in color in my teeth. i want to get a permanent teeth whitening procedure but m not sure about the risks or which one should i go for ? i have been through teeth scaling and polishing which worked fine for me at the time but didnt really help in the overall color whitening . can u pls guide me about which procedure shud i go through and if i shud do it at all or not? the process i went through was good enough for particular stains on my teeth but i need a total color whitener tht wi ll help to whiten the teeth and not only remove stains. i read through the internet about bleaching and laser .dont know which one wud be best suitable for me .help.thanks
