Why do my molars have grooves?

The deep groves in our molars and premolars are there to provide traction as we chew. These same deep grooves in teeth can trap food and bacteria, increasing our chances of tooth decay.

Is it bad to have deep grooves in teeth?

Some of our teeth, particularly premolars and molars, have deep grooves referred to as pits and fissures. These deep grooves are unfortunately susceptible to tooth decay, as they easily attract and trap food particles and bacteria. It can be especially difficult to successfully clean these areas out with a tooth brush.

Why is incisor contact heavier with the intrusion of molar teeth?

Because the anterior bite was normal initially, the incisor contact has become heavier with the intrusion of the molar teeth. Continuous insertion of accentuated curve of Spee (sliding mechanics) or strong Gable bend (loop mechanics) is usually needed to solve this problem. -> eventually total intrusion of the whole dentition has resulted.

How is molar intrusion used to correct anterior open bite?

Two Types of Vertical Excess Molar intrusion itself is enough for correcting the vertical excess with anterior open bite, because the opened anterior teeth will be automatically seated down by the closureof the mandibular plane.

When do the upper lateral incisors come out?
