Teething is the process by which an infant's first teeth (the deciduous teeth, often called "baby teeth" or "milk teeth") appear by emerging through the gums, typically arriving in pairs. The mandibular central incisors are the first primary teeth to erupt, usually between 6 and 10 months of age and usually causes discomfort and pain to the infant.
The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as "teething". These teeth are the only ones in the mouth until a person is about 6 years old creating the primary dentition stage.
Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
Symptoms of ADHD include inattentiveness, impulsiveness, and hyperactivity. Many of the behaviors that are associated with ADHD include poor control over actions resulting in disruptive behavior and academic problems.

Typically, all baby teeth will be present by the age of three. As for all adult teeth, they erupt between the ages 6 to 14, with the exception of the third molar, also known as the wisdom teeth which normally erupt between 17 and 25 years of age. If the tooth has yet to erupt by an appropriate age, panoramic x-rays are taken.
For instance, ADHD symptoms are associated with problems with emotional regulation, motivation, and arousal. [15] One study found a connection between emotional dysregulation at 5 and 10 months, and parent-reported problems with anger and distress at 18 months.
The signs of late congenital syphilis tend to reflect early damage to developing tissues that does not become apparent until years later, [20] such as Hutchinson's triad of Hutchinson's teeth (notched incisors), keratitis and deafness. [21] [22] Symptoms include: [21] Blunted upper incisor teeth known as Hutchinson's teeth, or mulberry molars [7]
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]
