Treatments, Signs, and Symptoms Dental caries, which is also referred to as tooth decay or cavities, is one of the most common and widespread persistent diseases today and is also one of the most preventable. When you eat certain foods, the bacteria on your teeth breaks them down and produces acids that have the ability to seriously damage the hard tissues of your tooth. The result is the formation of dental caries cavities.
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 Dental caries experiencing caries may not be aware of the disease. This is referred to as a white spot lesion, an incipient carious lesion or a "microcavity". Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated.

A lesion that appears dark brown and shiny suggests dental caries were once present but the demineralization process has stopped, leaving a stain. Active decay is lighter in color and dull in appearance.
The affected areas of the tooth change color and become soft to the touch. Once the decay passes through enamel, the dentinal tubules, which have passages to the nerve of the tooth, become exposed, resulting in pain that can be transient, temporarily worsening with exposure to heat, cold, or sweet foods and drinks.
When the decay has progressed enough to allow the bacteria to overwhelm the pulp tissue in the center of the tooth, a toothache can result and the pain will become more constant.
Death Dental caries the pulp tissue and infection are common consequences. The tooth will no longer be sensitive to hot or cold, but can be very tender to pressure. Dental caries can also cause bad breath and foul tastes.
Complications such as cavernous sinus thrombosis and Ludwig angina can be life-threatening. Four factors, namely, a suitable carbohydrate substrate 1micro-organisms in dental plaque 2a susceptible tooth surface 3 and time 4 ; must be present together for dental caries to occur 5.
Saliva 6 and fluoride 7 are modifying factors Four things are required for caries formation: The caries disease process does not have an inevitable outcome, and different individuals will be susceptible to different degrees depending on the shape of their teeth, oral hygiene habits, and the buffering capacity of their saliva.
Dental caries can occur on any surface of a tooth that is exposed to the oral cavity, but not the structures that are retained within the bone. Certain bacteria in the biofilm produce acid in the presence of fermentable carbohydrates such as sucrosefructoseand glucose.
The most common bacteria associated with dental cavities are the mutans streptococci, most prominently Streptococcus mutans and Streptococcus sobrinusand lactobacilli.
However, cariogenic bacteria the ones that can cause the disease are present in dental plaque, but they are usually in too low concentrations to cause problems unless there is a shift in the balance.
Streptococcus mutans and Lactobacillus species among them. Streptococcus mutans are gram-positive bacteria which constitute biofilms on the surface of teeth. These organisms can produce high levels of lactic acid following fermentation of dietary sugars and are resistant to the adverse effects of low pH, properties essential for cariogenic bacteria.
Bacteria collect around the teeth and gums in a sticky, creamy-coloured mass called plaquewhich serves as a biofilm. Some sites collect plaque more commonly than others, for example, sites with a low rate of salivary flow molar fissures.
Grooves on the occlusal surfaces of molar and premolar teeth provide microscopic retention sites for plaque bacteria, as do the interproximal sites. Plaque may also collect above or below the gingivawhere it is referred to as supra- or sub-gingival plaque, respectively.
These bacterial strains, most notably S. The process is dynamic, however, as remineralization can also occur if the acid is neutralized by saliva or mouthwash. Fluoride toothpaste or dental varnish may aid remineralization.
The impact such sugars have on the progress of dental caries is called cariogenicity. Sucrose, although a bound glucose and fructose unit, is in fact more cariogenic than a mixture of equal parts of glucose and fructose. This is due to the bacteria utilising the energy in the saccharide bond between the glucose and fructose subunits.
Net demineralization of dental hard tissues occurs below the critical pH 5. The frequency with which teeth are exposed to cariogenic acidic environments affects the likelihood of caries development.
As time progresses, the pH returns to normal due to the buffering capacity of saliva and the dissolved mineral content of tooth surfaces. During every exposure to the acidic environment, portions of the inorganic mineral content at the surface of teeth dissolve and can remain dissolved for two hours.
Evidence suggests that the introduction of fluoride treatments has slowed the process. Because the cementum enveloping the root surface is not nearly as durable as the enamel encasing the crown, root caries tends to progress much more rapidly than decay on other surfaces.
The progression and loss of mineralization on the root surface is 2.Dental caries or cavities, more commonly known as tooth decay, are caused by a breakdown of the tooth enamel. This breakdown is the result of bacteria on teeth that breakdown foods and produce acid that destroys tooth enamel and results in tooth decay.

Recommendations for Using Fluoride to Prevent and Control Dental Caries in the United States. Fluoride Recommendations Work Group. Steven M. Adair, D.D.S., M.S. School of Dentistry Medical College of Georgia Augusta, Georgia. Dental caries can occur on any surface of a tooth that is exposed to the oral cavity, but not the structures that are retained within the bone.
Tooth decay is caused by biofilm (dental plaque) lying on the teeth and maturing to become cariogenic (causing decay). Dental Caries (Tooth Decay) Dental caries (tooth decay) remains the most prevalent chronic disease in both children and adults, even though it is largely preventable.
Although caries has significantly decreased for most Americans over the past four decades, disparities remain among some population groups.
