Enamel may appear yellow/brown with discolouration and/or many pitted white-brown lesions similar to cavities. They are often described as "mottled teeth". [ 8 ] Fluorosis does not cause discolouration to the enamel directly, as upon eruption into the mouth, affected permanent teeth are not discoloured yet.
The enamel is fragile, the teeth appear yellow or brown, and surface stains build up more readily. [1] Dentinogenesis imperfecta is a defect of dentin formation, and the teeth may be discolored yellow-brown, deep amber or blue-grey with increased translucency. [1] Dentinal dysplasia is another disorder of dentin.
The normal temperature of the mouth ranges between 35 and 36 °C, and a two-degree (°C) change has been shown to drastically shift the dominant species in the plaque. [18] Redox reactions are carried out by aerobic bacteria. This keeps the oxygen levels in the mouth at a semi-stable homeostatic condition, which allows the bacteria to survive. [18]
These X-rays allow dentists to see if any small cavities are forming in between the teeth “so that we can either prevent it or reverse it before it becomes a big issue,” he tells Yahoo Life.
Fluoride’s dental health benefits were discovered in the early 1900s when a dentist in Colorado noticed several patients had brown stains on their teeth but no cavities. After researching the ...

Later, the fluoride is re-released into the oral cavity from these reservoirs which acts as protection for the teeth against cavities. [36] Currently, there is also no published evidence that indicates that professionally applied fluoride varnish is a risk factor for enamel fluorosis. The varnish is applied with a brush and sets within seconds.
However, the capacity for remineralization is limited, and if sugars enter the mouth too frequently then a net loss of minerals from enamel produces a cavity, through which bacteria can infect the inner tooth and destroy the latticework. This process requires many months or years. [8] [4]
