(caries) The decay of a tooth, in which it becomes softened, discolored, and/or porous.

(tooth decay) Infectious disease that attacks the teeth. Also called dental caries.

(tooth decay) Tooth decay is damage to a tooth's surface, or enamel. It happens when bacteria in your mouth make acids that attack the enamel. Tooth decay can lead to cavities (dental caries), which are holes in your teeth. If tooth decay is not treated, it can cause pain, infection, and even tooth loss. Our mouths are full of bacteria. Some bacteria are helpful. But some can be harmful, including the ones that play a role in tooth decay. These bacteria combine with food to form a soft, sticky film called plaque. The bacteria in plaque use the sugar and starch in what you eat and drink to make acids. The acids begin to eat away at the minerals on your enamel. Over time, the plaque can harden into tartar. Besides damaging your teeth, plaque and tartar can also irritate your gums and cause gum disease. You get fluoride from toothpaste, water, and other sources. This fluoride, along with your salvia, helps the enamel repair itself by replacing the minerals. Your teeth go through this natural process of losing minerals and regaining minerals all day long. But if you don't take care of your teeth and/or you eat and drink lots of sugary or starchy things, your enamel will keep losing minerals. This leads to tooth decay. A white spot may appear where minerals have been lost. This is an early sign of tooth decay. You may be able to stop or reverse the decay at this point. Your enamel can still repair itself, if you take better care of your teeth and limit sugary/starchy foods and drinks. But if the tooth decay process continues, more minerals are lost. Over time, the enamel is weakened and destroyed, forming a cavity. A cavity is a hole in your tooth. It is permanent damage that a dentist has to repair with a filling. The main risk factors for tooth decay are not taking care of your teeth and having too many sugary or starchy foods and drinks. Some people have a higher risk of tooth decay, including people who: Don't have enough saliva, because of medicines, certain diseases, or some cancer treatments; Don't get enough fluoride; Are very young. Babies and toddlers who drink from bottles are at risk, especially if they are given juice or get bottles at bedtime. This exposes their teeth to sugars for long periods of time.; Are older. Many older adults have receding gums and more wear on their teeth. These raise the risk of decay on the exposed root surfaces of their teeth. In early tooth decay, you usually don't have symptoms. As tooth decay gets worse, it can cause: A toothache (tooth pain); Tooth sensitivity to sweets, hot, or cold; White or brown stains on the surface of a tooth; A cavity; An infection, which can lead to an abscess (pocket of pus) forming. The abscess can cause pain, facial swelling, and fever. Dentists usually find tooth decay and cavities by looking at your teeth and probing them with dental instruments. Your dentist will also ask if you have any symptoms. Sometimes you may need a dental x-ray. There are several treatments for tooth decay and cavities. Which treatment you get depends on how bad the problem is: Fluoride treatments. If you have early tooth decay, a fluoride treatment can help the enamel to repair itself.; Fillings. If you have a typical cavity, your dentist will remove the decayed tooth tissue and then restore the tooth by filling it with a filling material.; Root canal. If the damage to the tooth and/or an infection spreads to the pulp (inside of the tooth), you might need a root canal. Your dentist will remove the decayed pulp and clean inside the tooth and root. The next step is to fill the tooth with a temporary filling. Then you will need to come back to get a permanent filling or a crown (a cover on the tooth).; Extraction (pulling the tooth). In the most severe cases, when the damage to the pulp cannot be fixed, your dentist may pull the tooth. Your dentist will suggest that you get a bridge or implant to replace the missing tooth. Otherwise, the teeth next to the gap may move over and change your bite. There are steps that you can take to prevent tooth decay: Make sure that you get enough fluoride by Brushing with a fluoride toothpaste; Drinking tap water with fluoride. Most bottled water does not contain fluoride.; Using fluoride mouth...

(carious teeth) Caries is a multifactorial bacterial infection affecting the structure of the tooth. This term has been used to describe the presence of more than expected dental caries.

Demineralization and breakdown of tooth enamel due to bacterial infection.

Localized destruction of calcified tissue initiated on the tooth surface by decalcification of the enamel of the teeth, followed by enzymatic lysis of organic structures, leading to cavity formation that, if left untreated penetrates the enamel and dentin and may reach the pulp.

Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formation. If left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp.

A disorder characterized by the decay of a tooth, in which it becomes softened, discolored and/or porous.

Caries is tooth decay, commonly called cavities. The symptoms--tender, painful teeth--appear late. Diagnosis is based on inspection, probing of the enamel surface with a fine metal instrument, and dental x-rays. Treatment involves removing affected tooth structure and restoring it with various materials. Fluoride, diligent dental...

Caries, cavity or decay of a tooth, a localized disease that begins at the surface of the tooth and may progress through the dentine into the pulp cavity. It is believed that the action of microorganisms in the mouth on ingested sugars and carbohydrates produces acids that eat away the enamel. The...
