In some patients, contact of the anterior teeth does not occur, favoring the overload and wear of the posterior teeth. The most common causes of this condition are related to childhood habits such as "thumb sucking" or putting the tongue between these teeth when swallowing, which we commonly call atypical swallowing.
The treatment of this malocclusion involves the use of invisalign aligners and the correction of the habit with the help of speech therapists.
