Mechanical trauma, e.g. caused by a sharp edge on a denture, or a broken tooth, may cause white patches which appear very similar to leukoplakia. However, these white patches represent a normal hyperkeratotic reaction, similar to a callus on the skin, and will resolve when the cause is removed. [ 1 ]
The "very mild" (and most common) form of fluorosis, is characterized by small, opaque, "paper white" areas scattered irregularly over the tooth, covering less than 25% of the tooth surface. In the "mild" form of the disease, these mottled patches can involve up to half of the surface area of the teeth.

Hyperplastic reactive lesions or nodular swellings: These occur in the oral mucosa due to low grade inflammation or trauma. They develop where the mucosa is ...
They are small white or yellow cystic vesicles (1 to 3 mm in size) often seen in the median palatal raphe of the mouth of newborn infants (occur in 60-85% of newborns). They are typically seen on the roof of the mouth (palate) and are filled with keratin. They are caused by entrapped epithelium (fissural cyst) during the development of the palate.
