Toothpaste is useful in reducing swelling, as it has certain anti-inflammatory, antiseptic, and pain-relieving effects. For small localized edema, toothpaste can be gently applied to the affected area to relieve pain and reduce swelling. However, the effect of toothpaste is not particularly satisfactory if it is used only to reduce swelling, and other forms of treatment are needed. If the patient’s trauma area is relatively large, the ointment will certainly not play a significant role, you need to use magnesium sulfate solution for local wet compress treatment, but also need to carry out the affected area dressing treatment, in order to avoid the occurrence of infection, inflammation or septicemia of the wound and so on. Toothpaste can reduce edema, but the effect is not very large, it is recommended to go to the hospital to do timely examination and treatment.
