What is the direct answer?
What does this question mean?

What can you do next?
Use only a dental product according to its instructions, and stop if you develop significant sensitivity or gum irritation. Do not swallow peroxide or use concentrated household products in the mouth, because the tissue response depends on concentration and exposure.
When should you seek dental care?
Have a dental examination before whitening if you have pain, cavities, gum inflammation, enamel defects, or extensive restorations. Seek care for chemical burns, persistent sensitivity, or uneven color after use.

Ask which peroxide formulation and delivery method suit your teeth, whether existing restorations will match afterward, and how sensitivity or gum contact will be managed.
