Hello, Thanks for your query. A tooth extraction can trigger difficulty with headache and dizziness. The reason is that the ear, nose, throat and teeth are intimately connected. In this setting the nerves which deliver sensation and pain to the teeth are disturbed and inflamed. I am confident this will resolve over time with the raking process after your tooth extraction. For now I recommend you maintain good hydration and consider maintaining steady doses of anti-inflammatory doses of ibuprofen. This will also help the healing process. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
