It sounds like your jaw clicking when eating hard foods is likely related to the temporomandibular joint (TMJ), which can sometimes cause a slipping or clicking sensation without pain. This is often due to the movement of the joint or the disc inside it.

• This condition is usually benign if there is no pain, swelling, or difficulty opening your mouth.
• Avoid very hard or chewy foods that might strain the joint.
• Gentle jaw exercises or warm compresses may help if you notice any stiffness or discomfort later.

If the clicking worsens, becomes painful, or you experience jaw locking or difficulty chewing, it would be best to see a dentist or an oral and maxillofacial specialist for a thorough evaluation. They can assess for TMJ disorders and recommend appropriate treatment.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
