(A) A small spot of decay visible on the surface of a tooth. (B) The radiograph reveals an extensive region of demineralization within the dentin (arrows). (C) A hole is discovered on the side of the tooth at the beginning of decay removal. (D) All decay removed; ready for a filling. A person experiencing caries may not be aware of the disease ...
[3] [5] Eventually, the coronal tooth area (near the crown) can be affected by the decay and erosion. [6] The dental caries of meth mouth often progress slowly, perhaps because their advancement is hindered by intermittent hygienic practices. [5] The decay can lead to tooth fractures and severe pain.

English: SVG version of image, adding several aspects not reproducible by any photograph, including the shape and orientation of the enamel rods (interlocking keyholes oriented away from the surface of the dentin) and of the dentin tubules (S-shaped fibers stretching between the pulp and the enamel/ cementum layer, thicker on the pulp end and narrow on the enamel end).
When it comes to repairing teeth affected by Early Childhood Caries, the extent of tooth decay will guide the choice of treatment. For moderate to severe decay, stainless steel crowns are a common option. These crowns are ready-made and can be tailored to fit over a child's primary molar. The crowns are then fixed in place to restore the tooth.
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Progression and build-up of dental plaque can give rise to tooth decay – the localised destruction of the tissues of the tooth by acid produced from the bacterial degradation of fermentable sugar – and periodontal problems such as gingivitis and periodontitis; [3] hence it is important to disrupt the mass of bacteria and remove it.

The two main classification systems are described below. Others include the tooth surface fluorosis index (Horowitz et al. 1984), which combines Deans index and the TF index; and the fluorosis risk index (Pendrys 1990), which is intended to define the time at which fluoride exposure occurs, and relates fluorosis risk with tooth development stage.
