There’s no magic cure to make a burn heal faster, but there are things you should avoid that can make it worse. According to the experts, this includes very hot food (obviously); acidic or spicy food, which can increase irritation; and crunchy foods like chips, which can scratch and damage the fragile, burned skin. Stick to foods like yogurt, oatmeal, or mashed potatoes, Bruce says.
Just like after you get your wisdom teeth out, after a burn you’ll want to keep your mouth clean. “Your mouth is naturally filled with bacteria and most of it is harmless, but you still want to keep your burn very clean to avoid an infection,” Bruce says. So don’t touch, poke, or pick at the burn with your germy fingers.
You should brush your teeth — but be gentle or use a soft toothbrush — and do a saltwater rinse two to three times a day. The latter will kill bacteria and it’ll be more soothing than mouthwash. A saltwater rinse is just 1 cup of warm water with ½ teaspoon of table salt, Bruce says. And as we said before, stick to over-the-counter pain meds or numbing gels to manage the pain.
