Laser teeth whitening provides an easy and comfortable way to achieve immediate results. Patients who suffer from teeth that are severely stained from chemicals or medications, can achieve extraordinary results with this 20 minute procedure. Laser teeth whitening also renders a positive side effect for sensitive teeth. Post treatment, previously sensitive teeth are de-sensitized to hot, cold or sweets. Gentle whitening can be done incrementally, to reach the desired shade of white, for some patients, teeth are brightened up to 9 shades whiter.
