Just felt tooth break...OMG..flippin out!!!!?

Root canal therapy can weaken the tooth, which is why you're often recommended to get a crown (expensive!). anyway, yes, you probably cracked the tooth, but don't be freaking out, especially if there's not blood, and you're not in pain, and the tooth is still there. Just make an appointment to see your dentist soon and explain to them what happened. you still need to see them, even if you're not in pain, as the crack in the tooth might lead to an infection, or your tooth getting more damaged and falling out later, or having to be removed altogether.
