Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth while swallowing, chewing, resting, or speaking. Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites.
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [2]
The basic sound, or phoneme, is selected as a target for treatment. Typically the position of the sound within a word is considered and targeted.

Non-eruption of non-ankylosed teeth occurs due to an eruption mechanism that has failed leading to a posterior unilateral/bilateral open bite. [28] Infra occlusion is the primary hallmark of PFE. Primary teeth are most commonly affected and normally all teeth distal to the most mesially affected tooth will show characteristics of this disease.
The [t] sound is a very common sound cross-linguistically. [1] Most languages have at least a plain [t], and some distinguish more than one variety. Some languages without a [t] are colloquial Samoan (which also lacks an [n]), Abau, and Nǁng of South Africa. [citation needed]
