How long does whitening last? Are the results permanent?
The results are not permanent. It can last a few months to years depending on the color of your teeth, lifestyle habits and if you follow up with maintenance bleaching. Gray teeth do not usually whiten as much or last as long although with Power Whitening we can get great good results. For some people drinking a lot of coffee and red wine can cause the teeth to get darker sooner but with follow-up at home maintenance you can keep your teeth looking beautiful.
