Crooked Teeth In Babies

Crooked teeth in Babies. Occlusion refers to the relationship between the teeth of both jaws. A malocclusion is not only associated with the bad dental position, but rather it is any alteration in the growth of the maxillary or mandibular bone and/or dental positions that prevent correct chewing function.  In turn it brings subsequent consequences for the teeth themselves, the gums, and bones that support them, the temporal-mandibular joint, and facial aesthetics.

According to the WHO, dental malocclusions are the third most common oral disease after dental caries and periodontal disease worldwide.


What Causes Malocclusion in Babies?

Different factors or causes can cause malocclusions; among them, we have:

  • Heredity:

That which is transmitted from parents to children, presenting an inadequate relationship between the size of the jaws and teeth and can be transmitted between families.


  • Acquired factors:

Those habits that the baby or infant acquires in the first years of life; among them, we have digital suction, pacifier use, which influence the development of malocclusion.


  •   Abnormal habits:

Here we have the presence of atypical swallowing, tongue or lip interposition, and oral breathing associated with adenotonsillar hypertrophy or allergic rhinitis.


  •   Local factors:

These include premature loss of primary teeth, either caused by caries or trauma.

What Habits Cause Malocclusion?

  •     Digital Suction:

This is normal early in life, in newborns, and during the first few months. The position of the thumb touches the palate fully, and the lower incisors are in contact on their incisal edge with the thumb knuckle.

It is believed that when the child is bored, anxious, or tired is when digital sucking happens, harmfully affecting the development of its normal occlusion, leading the child to a different bite (Open Bite).


  •     Use of pacifier, pacifier, or bottle:

It starts around the first six months of life. Pacifier or bottle sucking after one year of age is considered a harmful habit that can cause deformity in the teeth of small children and can cause open bite although less marked than thumb sucking.


How Can I Prevent Malocclusion?

Prevention should be timely to avoid the presence or aggravation of malocclusion; among them, we can do the following:


  • Eradicate sucking habits (pacifier, bottle, thumb sucking) before the age of two years to spontaneously correct the malocclusion caused by them.


  • Prevent children over five years of age from sucking their thumb because they are more at risk of developing malocclusion. This is because the advancement of the maxilla, as well as its narrowness, can cause an anterior open bite.


  • Avoid biting or placing items in the mouth for long periods, since doing so constantly can also lead to the presence of malocclusions or even tooth wear.


  • The intervention of the otorhinolaryngologist will be necessary in cases of adenotonsillar hypertrophy or allergic rhinitis. Since these cause, mouth breathing altering the relationship of the tongue and palate, and as a consequence, will lead to malocclusion problems in the long term.



  • Orthopedic treatments and preventive orthodontics guide the good growth and development of the occlusion. The Spanish Association of Orthodontic Specialists recommends to parents that all children have an orthodontic checkup before the age of seven.


  • Educate children to have good oral hygiene to avoid developing dental caries or periodontal disease, which can lead to premature tooth loss.


What Treatments Can Solve a Malocclusion? 

When identifying some of these bad oral habits in a patient the treatments and eliminating the bad habit, many times some intraoral devices will be used that help recover the correct function.

Also, in case of more developed malocclusions, depending on the evaluation of the specialists, orthopedic appliances or orthodontic appliances could be applied depending on the severity of the case.

It is vital to detect these habits at an early stage. Preventive treatment will avoid serious problems in the long term, so we recommend periodic checkups with our dentists in Oxnard, Santa Paula, Ventura, or Port Hueneme every six months as a preventive way.
