In-Office Whitening

The last whitening option that we will discuss is in-office whitening.  As the name implies, the whitening is done in the office and the procedure takes approximately 1 hour.  Since the treatment is done in the office, the highest concentration of peroxide is used to achieve a maximum whitening affect. Typically, a hydrogen peroxide of about 40% is used on the teeth. A protective material is placed on the gums to prevent the gel from irritating them.  The application is repeated 3-4 times within the hour until the desired affect is achieved.  With some systems, a light is used to activate the gel, but studies have shown that in-office whitening with or without the light achieve the same effect.

The results vary and what I have found is that to achieve the maximum effect, this treatment has to be done in conjunction with take-home whitening.  This way, the results are more dramatic and longer lasting as well.  For this reason, at Soho Dental, we always include take-home whitening trays and gel for our patients who have the in-office treatment.  This also allows them to touch up the whitening at home from time to time.

Many of you might have seen tooth whitening being offered in aesthetic spas, at the airport etc. Be careful of any claims that are made.  As a dentist, I can use the highest strength products and despite this, the results are variable. This is why, a proper assessment before treatment is essential so that that you can have an idea as to what kind of result to expect.

The pictures below show the results after 1 hour of in-office whitening.  These results are typical.  The teeth will whiten further as the patient continues  the process at home with the take home whitening trays as described in the previous post.
