By Dr. Osvaldo Estevam ,DDS


Fractures

Dental fractures can occur for various reasons: from children playing on the playground to adults trying to open bottles of drinks with their teeth or pressure on the teeth from habits like grinding or bruxism.

There are cases where a filling might be too large resulting in weakened integrity of the tooth.

Teeth may become fractured due to trauma to the teeth and supporting structures by injury as a result of a sudden impact to the face or head caused by a fall, fight, car accident or through involvement in contact sports where no mouthguard is worn.

Chewing or biting hard foods, such as bones, ice, nuts, or hard candy can also cause the teeth to get fractured.
