<s>[INST] my dog head butted me on my chin and slammed my bottom teeth into my top left teeth yesterday. I only have 2 teeth on left side after my canines.Is it a bruised tooth or nerve and how long does the pain last?  Each time I eat the pain is almost unbearable.  Thank you [/INST] Thanks for your query, I have gone through your query. The pain can be secondary to the impact, or it can be because of the broken tooth. Nothing to be panic, consult an oral physician and get it evaluated, you need to take radiograph like IOP AR to confirm the diagnosis. Once the diagnosis is confirmed, we can treat accordingly with either root canal treatment or medication.Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole combination(if you are not allergic)I hope my answer will help you, take care. </s>
