Your teeth should not be used for anything other than chewing food, as doing so can damage them permanently. Never use your teeth to open bottles, rip open packaging or anything else they’re not designed for. If a tooth fractures, depending on the level of the fracture, they may need a filling or a crown and sometimes even a root canal to repair the tooth. In extreme cases, a fractured tooth will need to be extracted and replaced with an implant, bridge or denture. Take care of your pearly whites!
