Generally, tooth sensitivity is only experienced with highly concentrated hydrogen peroxide gel. Our products use carbamide peroxide gel, which does not typically cause tooth sensitivity. The home whitening kit comes with a remineralization gel, which eliminates any sensitivity that you may experience as well as strengthens your enamel.
Our gel is formulated with carbamide peroxide and typically does not cause tooth sensitivity. People with existing sensitivity, recently cracked teeth, micro-cracks, open cavities, leaking fillings, or other dental conditions that cause sensitivity may find that these conditions increase or prolong tooth sensitivity (or “zingers”) during the first 24–48 hours after treatment. If you experience zingers, try using a sensitive toothpaste to ease the discomfort. Brush your teeth with sensitive toothpaste until the sensitivity goes away. Wait until the zingers are gone before starting your treatment again. We also recommend using our Remineralizing Gel or Minerals™ Enamel Booster to help prevent or eliminate tooth sensitivity.
