Loose tooth front bottom crack in tooth small bump at bottom of tooth sometime with pulse in it no tooth pain is that normal?

No: This tooth needs to be evaluated by a dentist. Just because there is no pain does not mean that you don't need treatment.

Teeth: The symptoms you mention mean that you need to see your dentist. He/she will fix the situation and prevent things from getting worse. Peace and good health.

Evaluation: No, I'm afraid that's not normal. Please have your Dentist evaluate before your problem becomes exacerbated. Probability is that will only worsen, not self-heal.

Contact DDS: See your dentist ASAP for an evaluation. Possible history of past trauma or decay, if the tooth can be saved, treat it immediately, if the tooth is deemed non-restorable, have a treatment plan for the replacement if possible.
