What to do if the mouth is scalded by hot oil

Generally, the management of oral scald injuries caused by hot oil mainly includes immediate cooling, oral cleaning, medication for symptom relief, dietary adjustments, and local protection. A detailed analysis is as follows:

1. Immediate Cooling

Rinse the mouth with room-temperature or cold water immediately, holding it in the mouth for 3 to 5 minutes before spitting out; this process may be repeated several times. Hot oil has a high temperature and although contact time with oral mucosa is brief, it can cause deep tissue damage. Low temperature rapidly removes heat from the affected area, halting ongoing thermal injury to the mucosa, relieving pain, and reducing blister formation. Avoid rinsing with hot or irritating liquids, which may worsen the injury.

2. Oral Cleaning

Gently rinse the mouth with mild physiological saline solution 2–3 times daily. The oral cavity contains abundant bacteria, and mucosal barrier disruption after scalding increases infection risk. Saline helps clean residual oil and food debris from the wound surface, lowering the chance of infection and providing a clean environment for mucosal healing. Rinse gently to avoid damaging the injured tissue.

3. Medication for Symptom Relief

Medication should be used under medical guidance. For significant pain, topical application of compound benzocaine gel may be helpful. To prevent infection, chlorhexidine mouthwash can be used. To promote mucosal healing, Xiangfunxin liquid (Rehabilitation New Liquid) may be held in the mouth, or recombinant human epidermal growth factor gel may be applied topically.

4. Dietary Adjustments

Avoid spicy, hot, hard, or acidic foods in the short term. These foods directly irritate the injured area, increasing pain and inflammatory response, and may even cause wound breakdown. Choose cool or lukewarm, soft, liquid, or semi-liquid foods such as porridge, well-cooked noodles, and fruit juice to minimize friction and irritation to the wound.

5. Local Protection

Avoid biting or repeatedly licking the injured area with teeth or tongue, as mechanical trauma may delay healing or lead to secondary infection. Speak slowly and minimize jaw movement to allow the injured site adequate rest and promote regeneration and repair of the mucosa.

In addition, during treatment, follow medical advice regarding proper medication use and closely monitor changes in the wound. If symptoms such as pus discharge, increased pain, fever, or difficulty swallowing occur, seek medical attention promptly. A healthcare professional should evaluate the condition and adjust the treatment plan as needed to ensure proper wound healing.
