Following a tooth removal, it is crucial to refrain from eating or drinking anything, including water, for a period of four hours. This allows the blood clot, which is fundamental for healing, to properly form and stabilise, thereby initiating the healing process. Disturbing this clot can result in a painful condition known as a dry socket, which significantly delays recovery. Therefore, it is highly recommended to ensure you are well-nourished and hydrated before your tooth extraction appointment to support optimal healing post-procedure.
