Windex for toothache is not real. Windex is not effective in relieving toothache. Windex is mainly composed of menthol, its effect is mainly to clear heat and detoxification, remove blood stasis and swelling, mostly used for mosquito bites, headaches and dizziness, etc., for the relief of toothache effect is not obvious. Toothache is the reaction of the nerve of the tooth after bacterial infection, which requires dental treatment to relieve. When the tooth decay is shallow, removing the infected tooth tissue can be filled directly, isolating the external cold, hot, sour and sweet stimulation of the dental nerve. Painful eating or even nighttime pain when the nerve is infected requires root canal treatment for relief. Therefore, windex is not a cure for toothache, and tooth pain requires a filling or root canal for relief, which can be done at the dentist.
