surfboard hit my jawww.. do i need a dentist?

so.. today i was surfing and my surfboard slammed into my jaw. my mouth closed really hard and my front two bottom teeth are in quite a lot of pain
There wasnt really any bleeding.. nothing noticible.... my tooth are still firm in place but it is really painful when the front two teeth touch anything. The backside of the teeth, around the gums are a little bit black? I checked web MD's symptom checker and it said trauma.... will it get better as time passes? because trying to eat is like torture!!
