Endodontists are specialists at diagnosing your symptoms and saving your teeth. Our smiles are built to last. In fact, tooth enamel — the outer surface of our teeth — is the hardest substance in the human body, stronger even than our bones. That tooth enamel can withstand a lot of wear and tear. But as we live longer, and expose our teeth to stresses like clenching, grinding or chewing on hard objects, we can put our smiles at risk. If you think you have a cracked tooth, it's important to seek treatment quickly, before the problem gets worse.
