The short answer
Whitening can irritate gums when gel contacts them, especially if the product is too strong, used too long, or held against the tissue by a poor-fitting tray.
What is the direct answer?
What does this question mean?
Peroxide whitening gel can cause temporary gum burning, whitening of the surface tissue, or soreness when it leaks beyond the tooth. Existing gingivitis, ulcers, recession, cracked trays, and untreated dental disease can increase irritation.
What can you do next?
Have the gums and teeth examined, use a correctly fitted tray or professionally controlled system, keep gel on the intended tooth surfaces, and stop if the gums burn or become sore. Rinse and follow the product instructions.
When should you seek dental care?
Seek dental care for persistent soreness, ulcers, swelling, bleeding, severe pain, or a reaction involving the lips or face.
What should you ask the dentist?
Are my gums healthy enough to whiten, does the tray seal correctly, and what should I do if gel touches the gumline?
