Understanding How Teeth Move: The Key to Successful Orthodontic Treatment

:arrow_right:Teeth move when pressure is applied, pushing the root in the desired direction.

:white_check_mark:Bone remodeling occurs when pressure is consistently applied to the tooth.

:timer_clock:Four hours of continuous force is needed for bone remodeling to begin.

:building_construction:The bone material is resorbed on one side and then backfilled on the other side to create space for tooth movement.

:stop_sign:Moving teeth too aggressively or using higher forces can lead to necrosis and slower tooth movement.

Why is wearing aligners consistently important?

—Aligners provide the necessary pressure to trigger bone remodeling, allowing teeth to move effectively.

Can I switch to the next set of aligners once I no longer feel pressure?

—No, the backfilling process takes time, and wearing aligners for the recommended duration ensures proper tooth movement.

Why do adult patients tend to have more tooth mobility?

—As we age, bone density may decrease, and periodontal health can affect tooth stability.

What happens if tooth movement is too aggressive?

—Heavy forces can cause necrosis, leading to longer tooth movement and potential mobility.

Why should tooth movement be supervised by a professional?

—To ensure proper progress, prevent excessive mobility, and address any issues that may arise during treatment.

00:12Teeth have a crown (visible part) and a root (embedded in bone).

01:59Teeth move when pressure is applied, pushing the root in the desired direction.

08:30Light continuous forces for four hours trigger bone remodeling.

10:40Bone resorption creates space, and backfilling with bone material stabilizes the tooth.

12:30Continuous aligner wear ensures consistent pressure for optimal tooth movement.

13:20Heavy forces can cause necrosis and longer tooth movement.

13:45Supervision by an orthodontist or dentist is important for progress monitoring and preventing excessive mobility.
