In orthodontics, an open bite is a type of malocclusion, or misalignment of the teeth, where the upper and lower teeth do not touch when the mouth is closed. This gap between the biting surfaces of the front and/or side teeth can affect both the functionality and aesthetics of a person's smile.

Dental crowns, also known as dental caps, are often used to support and restore a cracked tooth. When a tooth is cracked, the structural integrity of the tooth may be compromised, and it may become weak or susceptible to further damage. Dental crowns are an effective treatment option to address this issue.

Pain when biting on a tooth, also known as occlusal pain, can be caused by various dental issues. It's essential to identify the underlying cause of the pain in order to address it appropriately.
