Crazes: They are often very little, vertical cracks that do not endanger the teeth. Most dentists regard these surface scratches on the teeth to be a natural feature of the tooth biology. Health-related therapies for crazes are hardly ever necessary, but a number of cosmetic procedures can be used to lessen their undesirable visual effects.

Oblique supragingival cracks:  Only the crown of the tooth is affected by these fissures; they do not go past the gum line. Generally, the tooth’s afflicted area will finally break off. The tooth pulp, which houses the nerves and blood vessels, won’t be harmed, so there won’t be much discomfort.

Oblique subgingival cracks: The cracks extend past the gum line and even past the jawbone itself. Unless the dentist decides to remove it, a broken piece normally stays connected. Oblique subgingival cracks are uncomfortable and may need periodontal surgery (to expose the crown) as well as endodontic therapy to insert a crown or other restorative device.

Vertical furcation cracks:  The cracks develop as a result of the tooth roots separating. This sort of crack nearly often damages the tooth’s nerve. Root canal therapy and a crown can preserve the tooth because it won’t normally separate entirely.

Irregular root fractures: The surface of the tooth is often unaffected by these cracks. In reality, the damage is only visible behind the gum line and, in most cases, below the jawbone. The degree to which root canal treatment is an option depends on how close the fracture is to the tooth’s surface. To treat this type of fracture, however, extraction is almost always the sole alternative.

Vertical apical root cracks: The apex, or tip of the root, is where these fissures appear. From a dental standpoint, the tooth does not need to be extracted, but because of the intense pain, many patients ask for this. Root canal therapy temporarily relieves the discomfort, but in most cases, teeth with such cracks must be removed.
