Overnumbered teeth in children in Lecce: signs, diagnosis and possible treatments | Dentistry study Stere

The appearance of an extra small tooth or the delay of a permanent incisive can surprise a family. In some cases the cause is an overnumbered tooth, i.e. an additional dental element compared to the normal number.

An extra tooth can already be visible in the mouth or remain included in the bone without symptoms. Location, shape and relationship with neighboring teeth change from case to case: for this reason a photo or simple tooth count is not enough to determine what to do.

The dental evaluation serves to confirm the presence of the overnnumerary, to understand whether it hinders eruption or changes spaces and choose between control, removal and orthodontic treatment, respecting age and development of teething.

What are the overlapping teeth in children

Overnumbered teeth are teeth that develop beyond the usual number of deciduous or permanent teeth; the condition is also called hyperdontia. They may appear in any area, but in the child one of the best known types is the meseodens, located among the upper central incisors.

Some extra elements resemble a normal tooth, while others are small, conical or tuberculated. They can erode regularly, take an abnormal direction or remain included. The American Academy of Pediatric Dentistry emphasizes that form, position, orientation and dental development affect evaluation and possible surgical approach.


 

Because they can appear and what factors to consider

Alteration during tooth development

The formation of an additional element is linked to changes in processes that start and model the dental gem. It does not depend on a behavior of the child and is not caused by brushing, feeding or falling of a milk tooth.

Familiarity and individual predisposition

In some families, the overnumbered teeth are more often used, suggesting a hereditary component. However, familiarity does not allow itself to predict number, position or need for treatment and does not replace clinical examination.

Associated Syndrome Terms

Most cases may be isolated. The presence of numerous extra teeth or other signs of development may, however, require a wider framework, because some genetic or craniofacial conditions may be associated with hyperdontia.

Shape, seat and orientation of the extra tooth

A small monthsodens facing the palate does not have the same impact as an already erupted incisive. They count the distance from the nearby roots, the available space, the direction of growth and the possible obstacle to the eruption of the permanent tooth.

Signals that can make an extra tooth suspect

The most obvious signal is an additional element, often small or unusual, which appeared between or behind the teeth. Other clues are a permanent incisive that does not stop when the corresponding contralateral is already present, a milk tooth that remains long, a persistent central space, rotations or unexpected movements.

Many overnumbered teeth do not cause pain and are discovered during a control or radiographic examination performed for a precise question. Inflator, secretion, pain or trauma on the area require an evaluation, but their absence does not exclude that the element interferes with eruption.


 

Over-numbered tooth, late eruption and dairy holding

A delayed permanent does not automatically mean that there is an extra tooth. Eruption may vary physiologically or be hampered by lack of space, abnormal position, previous trauma, odontoma or other conditions. Also a detained milk tooth can be consequence, not cause, of the underlying problem.

Comparison with the tooth of the same type on the other side of the arch, the dental age and the sequence of permutations help to direct the diagnosis. Extract independently or force a milk tooth does not necessarily free the path of the permanent and can cause pain or injury.

How clinical and radiographic evaluation takes place

The visit reconstructs eruption times, familiarity, previous traumas and changes observed. The dentist counts the elements present, evaluates symmetry, spaces, mobility of milk teeth, position of the incisors and conditions of gums and mucous membranes.

When the clinical examination does not clarify the location and relationships, a targeted X-ray can confirm presence, orientation and proximity to the roots. The type of image must be chosen according to the question and with the minor exposure reasonably necessary. The AAPD information on development teeth recall the importance of examination, appropriate documentation, differential diagnosis and sequential plan.


 

Possible paths for overlapping teeth

Clinical monitoring over time

If the extra tooth does not hinder eruption, it does not damage neighboring structures and does not create functional or hygienic problems, the professional can propose programmed controls. Monitoring is not abandonment: it provides parameters and times defined according to growth.

Removal when an indication exists

Extraction can be evaluated when the overnumerary blocks or deviates a permanent, reduces space, damages a nearby tooth or presents other complications. The moment depends on the position and the radicular development: intervene immediately is not always the best choice.

Expectation and guidance of spontaneous eruption

After the removal of the obstacle, a permanent tooth can sometimes spontaneously erode if it has favourable space and direction. The control checks progress; there is no identical time for all and the absence of movement may require a new assessment.

Permanent tooth orthodontic recovery

When spontaneous eruption does not occur or the tooth is disallined, it can be indicated to create space and guide it orthodontically. Technique and time depend on age, location, roots and occlusion; fixed devices and other solutions are not automatically interchangeable.

What to do at home and what mistakes to avoid

It is useful to note when the milk tooth fell and when the corresponding permanents appeared, without turning the eruption tables into rigid deadlines. Periodic photos can document a change, but do not replace visits and diagnostic images when indicated.

You don't have to try to push, row or extract an extra item, or use elastics or devices purchased online to close a space. If pain, swelling, secretion, trauma or difficulty to bite, it is prudent to contact the study and do not administer drugs without medical indication.


 

Evaluation of overlapping teeth at Studio STERE di Lecce

At Studio STERE, in Via Giovanni Boccaccio 19 C/D/E in Lecce, the evaluation considers development of teething, present elements, spaces and eruptive path. When necessary, the case may supplement pediatric dentistry, radiographic diagnostics and orthodontics, without anticipating treatment before diagnosis.

Dr. Nicolò Stefanelli and Dr. Rosanna Renò have gained more than ten years of experience in the dental sector in Italy. The Studio remains open all summer until 31 August 2026, with visits to be agreed with the secretariat.

Tra i servizi verificati dello Studio rientra l’ortodonzia con allineatori trasparenti; Invisalign® è uno dei sistemi utilizzati quando la valutazione ortodontica ne indica l’impiego. Nei bambini con denti sovrannumerari la priorità è però definire eruzione, spazio e crescita: un allineatore non rimuove un ostacolo incluso e non sostituisce la diagnosi.

Domande frequenti sui denti sovrannumerari nei bambini

Un dente sovrannumerario deve sempre essere tolto?

No. La scelta dipende da posizione, effetti sull’eruzione, igiene, sintomi e rischio per i denti vicini. Alcuni elementi possono essere monitorati; altri richiedono rimozione in un momento pianificato.

Che cos’è un mesiodens?

È un dente sovrannumerario situato nella zona tra gli incisivi centrali superiori. Può essere visibile oppure incluso e può associarsi a ritardo eruttivo, rotazione o spazio tra gli incisivi.

Una radiografia è sempre necessaria?

Non in ogni controllo, ma spesso è utile quando il dente extra non è visibile o occorre definirne rapporti e orientamento. L’esame viene scelto solo se può rispondere a un quesito clinico concreto.

Dopo la rimozione il dente permanente scende da solo?

Può accadere, soprattutto se esistono spazio e direzione favorevoli, ma non è garantito. Età, posizione e sviluppo radicolare influenzano la possibilità e i tempi dell’eruzione spontanea.

When should I book a check?

Quando compare un dente in più, un incisivo erompe molto dopo quello controlaterale, un dente da latte rimane oltre la permuta attesa o compaiono spostamenti, dolore o gonfiore.
