Whitening gels penetrate your teeth to remove stains and whiten your smile. The gel is sticky and viscous so it stays in place and can continue to whiten your teeth for the duration of the treatment.
Teeth whitening results are very stable, leaving you with a stunning smile long after treatment is over. However, things like genetics, diet, age, some medications (like tetracycline), and certain habits (like smoking) may affect the length of your whitening results. Fortunately, touch-up treatments are quick and easy.
Tooth sensitivity is a relatively common side effect of teeth whitening. If sensitivity occurs, it is often temporary and will go away once you’ve completed the whitening process.
