Dental caries also known as tooth decay or a cavity, is an infection, bacterial in origin that causes the demineralization and destruction of the hard tissues of the teeth.

What is dental caries in medical terms?
Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.
What is dental caries and how can it be prevented?
A cavity is a hole in a tooth that develops from tooth decay. Cavities form when acids in the mouth wear down, or erode, a tooth’s hard outer layer (enamel). Anyone can get a cavity. Proper brushing, flossing and dental cleanings can prevent cavities (sometimes called dental caries).
What is the mechanism of dental caries?
Streptococcus mutans, which causes caries, adheres to the teeth and produces plaque, metabolizes carbohydrates contained in food (sugar in particular) and produces acid inside plaque. This acid dissolves the calcium or phosphorus that composes teeth, causing caries.
What is caries Class 11?
The breakdown of teeth by bacterial infection is known as dental caries or tooth decay. Commonly dental caries are referred to as cavities of teeth.
What are dental caries how can these be prevented Class 10?
Dental caries is caused by the action of acids on the enamel surface. The acid is produced when sugars (mainly sucrose) in foods or drinks react with bacteria present in the dental biofilm (plaque) on the tooth surface. Was this answer helpful?
What bacteria causes dental caries?
Etiology. Streptococcus mutans is the main cause of dental decay. Various lactobacilli are associated with progression of the lesion.
What are the classification of dental caries?
Caries classification according to severity The appearance of interproximal caries can be classified as incipient, moderate, advanced, or severe, depending on the amount of enamel and dentin involved in the caries process.
What are the 4 causes of tooth decay?
- 1) Poor oral hygiene. By far, oral hygiene problems are one of the main causes of tooth decay.
- 2) Poor diet choices. Patients who consume a diet that heavily consists of sticky or acidic foods and beverages are setting themselves up for tooth decay.
- 3) Location of the tooth.
- 4) Stomach acid.
What is the difference between cavity and caries?
Dental Caries (or Tooth Decay) Ultimately Develop into Cavities. As acidic by-products from bacteria continue to break down tooth enamel, eventually caries extend closer to the dentin or inner tooth layer.
How can dental caries affect your health?
Tooth decay does more damage than simply breaking down your teeth. It can lead to infections that can spread to the other parts of the body, it can increase your risk of heart disease and it can weaken your immune system.
What are 5 causes of tooth decay?
- Poor Diet. A poor diet, namely one high in sugars and starches, is one of the leading causes of tooth decay.
- Poor Dental Hygiene Habits.
- Dry Mouth.
- An Untreated Medical Disease or Disorder.
- Putting Off Visits to the Dentist.
Is dental caries a disease?
Dental caries is the most common chronic disease in children: it is about five times as common as asthma and seven times as common as hay fever. The most common cause of tooth loss among adults is untreated periodontal disease. Fifty-three million people live with untreated tooth decay in their permanent teeth.
What are the three factors necessary for the formation of dental caries?
The 3 main factors that lead to dental caries are sugars, oral bacteria and the time these are combined in the presence of the tooth.
What are the four main types of caries?
- Initial caries, caries in the spot stage or, as it is also called “white caries”. At this stage, a matte light spot is formed on the enamel surface at the place of enamel demineralization.
- Superficial caries.
- Medium caries.
- Deep caries.
What is a Class 3 cavity?
A cavity that occurs between front teeth is referred to as a class 3. Food collects between teeth. Sugars within food are converted to acids that decalcify enamel. Continued destruction forms a hole and therefore, the term cavity.
What causes tooth decay class 10?
Tooth decay is caused by bacteria and other things. It can happen when foods containing carbohydrates (sugars and starches) are left on the teeth. Such foods include milk, soda, raisins, candy, cake, fruit juices, cereals, and bread. Bacteria that normally live in the mouth change these foods, making acids.
How can 5 points prevent tooth decay?
- Keep Up with Brushing and Flossing.
- Visit Brock and Casas Every Six Months.
- Fluoride Treatments and Sealants.
- Eat Less Sugar and More Fiber.
- Educate Your Children About Oral Health.
Why is tooth decay painful?
Over time, these bacteria can eat into the enamel of the teeth, eventually causing decay deep in the tooth. These bacteria form biofilms that cause plaque, making them more difficult to remove. Over time, the bacteria damage the sensitive pulp and nerve of the tooth, causing cavity pain.
What are the two types of dental caries described by location?
Dental caries come in two forms: Pit-and-fissure Cavities, which commonly form on the chewing surfaces of back teeth, and. Smooth-surface Cavities, which form slowly on the exterior flat surfaces of teeth.
What is dental caries PDF?
Case Definition: Dental caries is an infectious microbiologic disease of the calcified tissues of the teeth, characterized by demineralization of the inorganic portion and destruction of the organic substance of the tooth. It is a common chronic disease that leads to pain and disability across all age groups.
What is the biggest cause of cavities?
Cavities often develop in your back teeth like the molars and premolars. These teeth have deep grooves and pits where food debris can accumulate. Foods that stick to your teeth like honey, sugar, dried fruit, cake, cookies, hard candy, and chips are more likely to cause cavities.
Can dental caries be cured?
If your cavity just started, a fluoride treatment may help restore your tooth’s enamel and can sometimes reverse a cavity in the very early stages. Professional fluoride treatments contain more fluoride than the amount found in tap water, toothpaste and mouth rinses.
How do you detect caries?
The most common method of caries detection is visual-tactile. Other non-invasive techniques for detection of early caries have been developed and investigated such as Quantitative Light-induced Fluorescence (QLF), DIAGNOdent (DD), Fibre-optic Transillumination (FOTI) and Electrical Conductance (EC).
What foods cause dental caries?
Sugary food and drinks are one of the main causes of tooth decay. Acid is produced when the bacteria in your mouth break down the sugar. The acid dissolves the tooth surface, which is the first stage of tooth decay.
