What does this question mean?
Have the dentist record your current shade and inspect for decay, cracks, gum recession, and defective restorations. The plan may use custom trays, controlled gel contact, and instructions to reduce gel touching the gums.
What can you do next?
Seek an examination before whitening if you have untreated pain, cavities, bleeding gums, exposed roots, or a single dark tooth. Stop and contact the dental team if marked gum irritation or persistent tooth pain develops.
When should you seek dental care?
Ask which Kör formulation and delivery method are planned, whether restorations will need replacement for shade matching, and how sensitivity will be handled. Ask how the final shade will be assessed.
