There is currently no reliable scientific evidence to suggest that toothpaste can alleviate burns. The cooling sensation after application occurs only on the skin's surface, failing to reduce heat in the underlying damaged tissues, and therefore does not decrease the burn's severity.

Motorbike exhaust burns are a common accident among children, typically occurring on the lower leg or arm from accidental contact with a hot exhaust pipe. The severity of the burn varies based on the exhaust temperature, contact duration, and initial first aid. Mild cases cause only skin redness and stinging pain, while more severe burns can result in blisters, deep tissue damage, and a high risk of scarring if not treated properly.

When a child sustains a burn, immediate first aid is crucial. First, move the child away from the burn source and remove any clothing around the injured area. Then, cool the burn under gently running, clean, cool water for about 20 minutes, ideally within the first 30 minutes after the accident. Do not use ice or direct ice packs, as this can worsen tissue damage.

After cooling, gently wash the burn with clean water or physiological saline and cover it with non-stick sterile gauze to protect the wound. Do not puncture blisters or apply any medication, cream, or other products to the burn without a doctor's instructions.

Children require medical attention if the burn has blisters, is suspected to be deep, covers a large area, or is located on sensitive parts such as the face, hands, feet, or genitals. For young children, parents should also seek early medical examination so a doctor can assess the extent of the injury, minimizing the risk of infection and scarring.

Recovery time depends on the burn's severity and the care provided. Superficial burns typically heal in about two weeks with proper management, while deep burns may take longer and carry a higher risk of scarring. During care, it is essential to change bandages as instructed, keep the wound clean, ensure adequate nutrition, and provide sufficient hydration to support tissue regeneration.

Beyond toothpaste, parents should also avoid applying snake fat, egg whites, fish sauce, fresh turmeric, or other folk remedies to burns. These can increase the risk of infection and complicate treatment. If the wound shows increased swelling or pain, discharge, a foul odor, if the child develops a fever, or experiences prolonged pain, parents must take the child to the hospital for prompt examination and treatment.
