Double row teeth in children: when the permanent pounces behind | Dentistry study Stere
A permanent incisor appears behind the milk tooth, which is still present. For a family it may seem that a second row has appeared.
The appearance does not automatically mean that there are extra teeth or need an appliance immediately.
The visit clarifies what elements are present, how mobile the deciduous and which space has the permanent to continue its path.
What does it mean to have teeth in double row
The expression describes an aspect, not a diagnosis. During the permutation a permanent incisive can emerge on the side of the tongue while the deciduous predecessor has not yet fallen. The situation should be interpreted in the overall teething.
Four elements that change the decision
Identity of the two teeth
The professional recognizes deciduous and permanent and checks that there is no additional element.
Mobility of milk tooth
Mobility helps to understand the permutation, but it should not be provoked by forcing the tooth at home.
Space in the arch
Availability of space and relationships between teeth guide the observation or the need for intervention.
Location and development
Direction of eruption, any obstacles and previous traumas can change the path.
When organizing control
A permanent visible behind a still firm deciduous deserves evaluation, especially if the situation does not evolve. Pain, swelling, trauma or difficulty in the bite require faster contact. The absence of pain does not clarify the available space.
It is not always a sovereign tooth
An additional element was formed in hyperdontia. In the overlap during the permutation, the predecessor and successor may be present. Even the ectopic eruption of a molar is a different problem, with own anatomical relationships.

What assesses the dentist
The visit considers dental age, mobility, permutation symmetry and occlusion. Any X-rays answer specific questions about presence, roots or location: they are not required only because a photo shows two files.
Observation and treatment according to the case
Wait with a program
If the picture is favourable it can be indicated to observe the fall of the deciduous and the evolution of the permanent.
Evaluate the tenth prisoner
When necessary, we consider the professional extraction of the milk tooth, after clarifying relations with the successor.
Reevaluate alignment
The position can change during the eruption, but you cannot promise that each tooth will straighten itself.
Study space if needed
A persistent problem may require orthodontic evaluation. The double row does not determine by itself type and time of the appliance.
What not to do with a tooth still present
Do not use wires, pliers or improvised tractions to extract the deciduous. Do not push the permanent with your fingers and do not buy devices to correct it. Gently clean both surfaces and report difficulties.

It is possible a change, but it is not guaranteed for each case.
Can I push it with my fingers?
No. Domestic manoeuvres do not replace an assessment.
