The eruption of 12 year old molars, also known as second molars, can significantly impact
orthodontic treatment. Here’s how:
1. Alignment and bite: The 12-year old molars are crucial for achieving a proper bite
(occlusion). As they emerge, they can shift the position of other teeth, potentially
affecting the overall alignment that braces or other orthodontic devices are trying to
achieve.
2. Timing of treatment: Orthodontists often wait for the 12 year old molars to emerge
before finalizing or adjusting a treatment plan. This ensures that any movement or
changes caused by these molars can be accounted for in the treatment.
3. Space considerations: The eruption of second molars can impact the available space in
the mouth. If there isn’t enough space, it might lead to crowding or misalignment, which
could require adjustments in orthodontic appliances or, in some cases, the removal of
teeth to create space.
4. Retention phase: After braces are removed, retainers are used to maintain teeth position.
The eruption of 12 year old molars during this phase might necessitate adjustments to
retainers to ensure they fit properly and continue to hold the teeth in their desired
positions
5. Potential for additional treatment: If the second molars do not erupt as expected or
cause significant misalignment, additional orthodontic treatment might be required, even
if the initial phase of treatment was successful.
In summary, the eruption of the 12 year old molars is a critical factor in orthodontic planning and
treatment, affecting timing, alignment, and the overall success of the treatment.
