Crest 3d white strips gum irritation

Gum irritation from whitening strips usually occurs when peroxide gel overlaps the gingiva or remains in contact with it for too long.

Whitening strips carry a peroxide-containing film against the front teeth. The gel can irritate the gum margin, especially if the strip is folded onto the gums, the tissue is already inflamed, or the product is used more often or longer than directed.

Remove the strip, rinse with water, and pause whitening until the tissue feels normal. Do not cut or stack strips, press gel into the gumline, or apply another whitening product while the area is irritated.

See a dentist if burning, peeling, ulceration, bleeding, or swelling persists after stopping the strips. Urgent care is appropriate for facial swelling or trouble breathing or swallowing.

Ask whether the irritation is chemical, plaque-related, or caused by a damaged tooth. Ask about a tray design, concentration, wear time, and treatment plan that protects the gum margin.
