Trauma in the teeth

Falls are the main cause of dental trauma in children under five years, but it is from that age, product of games and sports accidents, that increase cases.

In children, they are caused mostly by sports activities and by adolescents and young adults, by accidents and fights.

Primary dentition

Many parents think that an injury to a baby tooth has no major repercussions; however, traumatism in the dental or alveolar area can affect oral health and aesthetics even if it is primary dentition.

Depending on the trauma, it can affect the germ of the permanent tooth that is in development, from defects in the formation of the matrix to alterations in the mineralization, or both.

Dental trauma, which occurs more frequently among men, should not be taken lightly.


  • Wear mouth guard when practicing contact sports.
  • Avoid fights or fights.
  • Avoid hard foods.
  • Always use a seat belt.

Management of injuries that affect the denture

A blow or bruise in the area of ​​the mouth or jaw can damage the denture or the tissues that support it, and no person is exempt from going through it; however, children, due to the activities they perform and their little sense of risk, face this type of accident more frequently.

The small ones usually suffer injuries in the tissues of support of the tooth, like avulsion, that is not more than the exit or expulsion of the tooth of his alveoli-bone; extrusion, which consists in the outward displacement of the alveolus (the tooth looks long); and intrusion or displacement of the tooth into the alveolus (the tooth looks short).

Intrusion is the most serious lesion of dental support tissues, because when the tooth moves inside the alveolar-bone it compresses the nerve and produces necrosis or tissue death.

The problem is that most parents do not pay due attention to their children’s dental injuries.

When the child falls or suffers some dental trauma, the parents review it and, seeing nothing abnormal in the teeth, they leave that trauma, that fall, to pass. And after 15 days or a month after that episode has occurred, the tooth begins to change color, the child begins to complain of pain when ingesting hot and cold things, and that is when the parents worry and take it to the dental office??

A dental trauma should not be overlooked, although at first sight there is no serious damage and even if it is a milk tooth, because some injuries affect the permanent tooth that is in formation.


What to do if you lose or move a tooth after a blow? Place the piece back into its cavity – always by manipulating it through the crown and go to the dentist immediately for replantation. Although it is not recommended to wash the tooth, if it should be rinsed, it should be without scrubbing.

If you cannot put the tooth back in its place, immerse it in whole milk or saliva to nourish the remaining cells of the surrounding ligament.

The tooth should not last more than three hours submerged after the trauma; If not, the treatment will not have a good prognosis? When the tissue inside the bone becomes necrotic, the organism rejects the tooth as a foreign body.


In addition to soft tissue injuries, there are other types of trauma, such as tooth fracture, which is more common among adolescents and adults.

The bone of adolescents and adults is stronger and does not easily allow the loosening or exit of its alveolus from the tooth, Explains the president of the Dominican Society of Endodontic.

In any case, it is up to the dentist to determine the type of injury and its treatment, and for that he must perform clinical and radiographic examinations.

The objective of the specialist is to protect the vitality of the dental pulp and that the tooth remains in the mouth fulfilling its aesthetic and functional role for many years. That’s why emergency care is followed up continuously.

The patient with dental trauma may require clinical and radiographic reviews for an average of five years to evaluate the signs and symptoms and treat any unfavorable consequences in time.

The consequences of a trauma can be evidenced up to 5 or 10 years after having suffered the accident? In cases that were not treated, the consequences will be more severe, including injuries such as calcification or obliteration of the root canal, root desorption, dyschromia or change of tooth color, among others??

The medical advances allow to improve the teeth of an adult who has suffered a dental trauma in his childhood.


The dentist handles the trauma depending on the type of injury:

  • In case of dislocations, avulsions, root fractures, a permanent tooth can be treated with endodontic (canal treatment) and splints to hold the piece.
  • Milk teeth could be made lumpectomy (channel treatment in milk teeth), but not using splints.
  • If crown fractures occur or compromise the dental nerve, in both cases endodontic treatments and reconstruction of the tooth will be performed.
  • If the fracture does not compromise the nerve, only reconstruction with resin is performed.
