Dentist burned my gums
A white, sore or peeling gum area after treatment may be a chemical or heat injury; care depends on its appearance and severity.
The short answer
A white, sore or peeling gum area after dental treatment may be a chemical or heat injury; care depends on its appearance and severity. The dentist should identify the material or instrument involved, examine the tissue, and check for infection or deeper damage.
Which dental materials or instruments can irritate gums?
The gum, or gingiva, can be irritated by concentrated whitening gel, etching gel, disinfectant, bonding resin, hot instruments, or prolonged pressure from a retractor or rubber dam. A superficial chemical injury often looks white because the outer epithelial cells have been damaged and may later shed.
How should you care for a sore gum after treatment?
Rinse gently with lukewarm salt water, keep brushing the unaffected teeth with a soft brush, and avoid alcohol mouthwash, smoking, spicy foods, and picking at the white tissue. Do not apply household chemicals or put aspirin directly on the gum; arrange a review so the area can be photographed and monitored.
When should a post-treatment gum injury be checked?
Contact the treating dental clinic promptly if pain is increasing, the area is spreading, bleeding persists, or the tissue is not improving. Seek urgent care for facial swelling, fever, pus, trouble swallowing, or trouble breathing.
What should you ask about the injured gum?
Ask which product or instrument contacted the gum, whether the injury is limited to the surface epithelium, and how it should be cleaned and reviewed. Ask whether a protective dressing, prescription pain relief, or treatment for an underlying burn or infection is needed.
Frequently asked questions
Can a dental chemical burn heal?
A superficial injury often heals as the damaged surface sheds and new epithelium forms, but a dentist should assess persistent or worsening tissue changes.
Should I brush the injured spot?
Clean the surrounding teeth gently, but do not scrub or pick the sore area; follow the treating dentist’s instructions for that site.
