What should you do for a cracked tooth

If you suspect a cracked tooth, stop chewing on that side, rinse with warm water, and call a dentist promptly. Save any broken pieces if they are large enough to bring in, and seek urgent care if pain is sharp with biting, temperature sensitivity is severe, or a piece of tooth is missing.

Cracks range from tiny hairline fractures that are hard to see to splits that reach the pulp or root. Common triggers include biting hard foods, grinding, old large fillings, and trauma. Some cracks cause brief pain when biting or releasing pressure; others stay quiet until bacteria reach the nerve. Because cracks can worsen quickly, delaying evaluation often leads to more complex treatment later. Your dentist may use magnification, bite tests, or imaging to locate the fracture and decide whether a filling, crown, root canal, or extraction is needed.

Key Points

  • Avoid chewing on the cracked side and skip hard, sticky, or crunchy foods.
  • Rinse gently and keep the area clean without aggressive probing.
  • Cover sharp edges with dental wax if they cut your tongue or cheek.
  • Sharp bite pain, lingering cold sensitivity, or swelling suggest faster care is needed.
  • Bring any sizable broken fragment to your appointment in a clean container.
  • Over-the-counter pain relief may help short-term, but it does not seal the crack.
  • Call same day if the tooth feels loose, the crack is visible and large, or gums swell.

What This Means for You

A cracked tooth needs professional assessment even when pain comes and goes. Protect the tooth from further force, manage discomfort carefully, and get examined soon so a small fracture does not become a split that cannot be saved. Urgent attention is especially important when biting pain, swelling, or a missing chunk appears.
