What should an international patient prepare before traveling to China for impacted wisdom tooth treatment?

You will need a valid passport and a medical visa (S or L visa) for treatment; many hospitals offer invitation letters to assist. Arrange for an English-speaking interpreter if needed, as most hospitals provide this service for international patients. Plan to stay in China for at least 5 to 7 days to allow for the procedure and initial recovery, and ensure you have a local contact or clinic for any post-operative concerns.
