Introduction

If the crack extends into the dentin and causes sensitivity to hot or cold, continued use of the front teeth to tear food will increase biting forces, causing the crack to progressively deepen. It may develop into a complete fracture within one to two months, and in severe cases, the tooth may break outright, making it impossible to save and requiring immediate treatment. Have an oral examination every three months so your dentist can monitor changes in the crack.

There is significant variation in how long a cracked front tooth can last. With proper care, a shallow crack may remain stable for 3–5 years, while a deep crack or poor maintenance might lead to failure within just 1–2 months—there is no fixed standard. If discomfort occurs, prompt medical attention is recommended.

If the crack is limited to the enamel layer and there is no sensitivity or pain, avoiding chewing hard foods (such as nuts or bones) and cleaning the teeth promptly after each meal can prevent the crack from spreading. In most cases, the condition can remain stable for 3–5 years or even longer without rapid deterioration.

If the crack extends into the dentin and causes sensitivity to hot or cold temperatures, continued use of the front teeth for tearing food will subject them to biting forces that progressively deepen the crack. This could result in a complete fracture within 1–2 months, potentially causing the tooth to split severely, making it non-viable and requiring immediate treatment.

Daily care should include using a soft-bristled electric toothbrush and avoiding habits such as biting thread or tearing open packages with the front teeth. If food becomes lodged in the crack, gently clean it with dental floss instead of picking at it aggressively. Schedule a dental check-up every three months to allow your dentist to monitor any changes in the crack.

Why haven't my front teeth grown back after falling out six months ago?

Incisors refer to the front teeth. In general, if incisors have not erupted six months after falling out, it may be related to delayed tooth development, premature loss of primary teeth, malnutrition, gingival hyperkeratosis, or abnormal tooth germ development. It is recommended that patients promptly visit a hospital and follow medical advice for treatment. In daily life, one should develop good habits and avoid eating overly hard foods.
