Cracked tooth: pain when biting and what to do next
A brief pain when chewing can sometimes point to a crack. Learn how to protect the tooth until your visit and when to seek urgent help.

Key takeaways
- Pain when biting can have several causes.
- Arrange a prompt visit if you suspect a crack.
- Keep a broken fragment in milk or saliva.
- Swelling with breathing difficulty is an emergency.
You bite down and feel a brief, sharp pain in one tooth. This does not prove that it is cracked: other problems can feel similar. If it keeps happening, arrange a dental visit soon, even if the discomfort settles between meals.
What should you notice?
A cracked tooth may hurt when chewing, including when releasing a bite, or react to hot and cold. Symptoms alone cannot tell you how deep a crack is. Tell the dentist when the problem began and whether there was an injury or a broken fragment.
While waiting: protect the tooth
Choose soft food and avoid chewing with the sore tooth. Avoid very hot or cold drinks. If you find a broken piece, keep it in a container of milk or saliva and bring it to the appointment; it may sometimes be used in the repair. Do not put aspirin directly on the tooth or gum.
What treatment might help?
Depending on the damage, options include reattaching the fragment, a filling or a crown. Root canal treatment may be needed if the pulp is affected. Some deep cracks mean that the tooth cannot be saved. An examination helps select an appropriate next step; it does not automatically commit you to a particular procedure.

When is it urgent?
Severe pain with fever, swelling or difficulty opening your mouth needs prompt assessment. Difficulty breathing, swallowing or speaking, substantial swelling inside the mouth or swelling around the eye requires immediate medical help. When booking at Plovdiv Dent, describe the symptoms so the next step can be discussed.
