Understanding Cracked Teeth – Causes, Symptoms & Treatment
Even though tooth enamel is incredibly strong, it’s also brittle and prone to cracking under pressure. Cracks can start small – often without obvious symptoms – but if left untreated, they can spread, causing pain, sensitivity and more complex dental problems. Early diagnosis offers the best chance of protecting the tooth and avoiding more invasive treatment.
What are cracked teeth?
A cracked tooth happens when there’s a fracture through the enamel and sometimes into the dentine (the softer, sensitive layer beneath). You may notice pain when biting, sensitivity to hot or cold or a piece of the tooth breaking away.
Why do cracks form in teeth?
Although enamel is the hardest material in the body, it has a brittle, glass-like structure. Cracks often form due to biting pressure, teeth grinding, trauma or chewing hard foods.
Do cracked teeth need treatment?
Yes. Cracks can spread over time. If the enamel crack reaches the dentine, it can cause significant pain and may lead to infections, root canals or even tooth loss if untreated.
How are cracked teeth treated?
Treatment depends on how early the crack is detected. Small cracks may be managed with fillings, onlays or crowns. If pain has already started, root canal treatment or, in severe cases, surgery might be needed to save the tooth.
How do I know if I have a cracked tooth?
In the early stages, cracks can be painless and hard to spot. Common signs include pain when biting or releasing pressure, sensitivity or feeling a rough edge. During your check-up, your dentist uses magnification to detect cracks and recommend the right treatment.
