Small Teeth (Microdontia)
Microdontia is the term used to describe the small size of the teeth, the most commonly affected teeth are the upper lateral incisors and third molars. In this, the tooth is smaller than the usual size. But to know about the abnormality we have to first know about the normal size so that we can differentiate between normal and abnormal. Small Teeth in adults are also seen occasionally.
Normal Shape and Size of Teeth
The normal shape and size could vary according to the jaw sizes but generally, the teeth size can be judged by observing the teeth. When your mouth is open half inch than 1 to 5 mm of front teeth must be seen. If your teeth are not visible than your teeth might be smaller in size then the normal.
This could be of various types and due to various reasons.
What are various Types of Small Teeth (Microdontia)
The small tooth could be of two types generalised and localised
Generalised Microdontia
The generalised microdontia is said when almost all the teeth are of small size. It could be subdivided as
True Generalised
When all the teeth are of small size, this condition is very rare and occurs in lack of growth hormone.
Relative Generalised
Actually, all the teeth are normal in size but they appear to be small due to the large jaw size.
Localised Microdontia
The localised microdontia occurs when only a few teeth are smaller than the other teeth. Most common in this is the maxillary lateral incisors which are also called peg shaped laterals (Peg Teeth). These are shaped as an inverted cone and have short root. Localised microdontia is far more common than the generalised microdontia.
Causes of Small Teeth (Microdontia)
There could be various causes/factors responsible for the small teeth in adults.
Little Jaws Big Smiles
There might be an increase in the size of a jaw which eventually leads to the appearance of teeth to be small.
Twisted Lateral Incisors
The lateral incisors are sometimes twisted and due to this, it appears to be small than usual.
Small Teeth Big Gums
Sometimes, due to the swelling of the gum tissues, the teeth get covered under it and appear to be small. This is very common in case of gum disease.
