1 Find the tooth and call your dentist. A tooth that is knocked out of a personâs mouth is called an avulsed tooth. Your best chance of saving the tooth is to re-implant it within 30 minutes of it being dislodged.  Hold the tooth only by the crown, not the roots. Touching the roots can kill them.
Other signs of tooth erosion include a yellow discolouration, rounded teeth, or even cracking. You can also damage tooth enamel by grinding your teeth, brushing too hard, or chewing on hard objects, such as pens. Alldritt says it's vital you protect every bit of enamel that you have.
