Are the results of this treatment permanent? If not, how long does it last? Is the whitening pen included in the deal?

After receiving our LED whitening procedure, it will last an average between 6 months to 2 years; this depends on each person's lifestyle and personal habits. The whitening pen is not included in this deal.
