Whitening will not hurt your teeth. If you already have sensitive teeth this will not enhance that sensitivity.
We use a product to coat and protect teeth after the appointment to curb post treatment sensitivity (stain- x ) and can work around sensitive or recessed areas. The Beautiful Bright Smile products have been researched are both safe and gentle on your teeth.
If you have sensitive teeth you may wish to choose our peroxide free whitening gel. Discuss this option with the technician.
