You can learn to care for their teeth well if you understand the structure of the teeth and oral cavity environment. The mouth or oral cavity includes the lips, teeth, gums, tongue, salivary glands, and the lining of the cheeks. The primary function of teeth is to chew the food to make it more digestible, but the teeth are also necessary to speak. The wheezing sounds like the letter “S” are produced when air passes between the teeth producing a hissing sound. The tongue has muscles that help to put food on the teeth to chew properly. The language also has receptors for taste are called taste buds. Chewing, the salivary glands secrete saliva containing enzymes such as amylase that break down complex carbohydrates to produce sugars digestible. It is important to practice good dental hygiene to prevent tooth decay and gum disease.

Teeth
Humans have two types of teeth. Primary teeth or baby teeth appear when children are six or seven months old. Most children have 20 baby teeth at three years. The primary teeth begin to be driven by permanent teeth at five or six years, and at age 14 primary teeth usually all have been replaced by 28 permanent teeth. Approximately 20 years, four teeth grow in the back of the mouth, completing the series of 32 adult teeth.

Children must learn to care for their teeth while they still have baby teeth. In this way, and know how to avoid cavities and gum disease when they have their permanent teeth.

Composition of the Teeth
Teeth and bones consist mainly of inorganic calcium phosphate called apatite. The most common form of the teeth is hydroxyapatite, Ca 5 (PO 4 ) 3 OH. However, hydroxide ions are frequently replaced by fluoride ions (F – ), forming fluorapatite, Ca 5 (PO 4 ) 3 F. Fluorapatite is more resistant to decay than hydroxyapatite. Tooth enamel is approximately 96% inorganic material, while the dentin beneath the enamel contains 70% inorganic material and the rest is collagen, a structural component adhesive. The teeth are developed by specialized cells that stimulate mineralization through specific proteins. Odontoblasts are cells in the pulp of the tooth dentin are life, while the ameloblasts, the enamel-producing cells, but are active before the eruption of teeth in the jaw. Therefore, the enamel lost by abrasion or decay can not be regenerated.

Avoid overuse and injury
Although teeth are the hardest parts of the human body can be damaged by using them inappropriately. Teeth may crack or chip chewing hard objects such as bones, uncorking bottles, or trying to crack nuts. Teeth also can break or dislodge the gum by strong impacts on the face and may have fallen from a bicycle or sports such as football, basketball, hockey, or boxing. Always wear mouth guards for sports aggressive and violent.

Acidic drinks damage teeth
What you eat, drink, or put in your mouth can affect your teeth. Dark beverages such as tea and coffee contain resins that accumulate on the teeth and give them a yellow pigment. Cigarettes and other products of snuff stain the teeth with tar and carcinogenic substances deposited in the soft tissues of the oral cavity. Drinks that contain citric acid or phosphoric acid dissolves the enamel and predispose the teeth to decay. [1] Many sports drinks like Gatorade, have a pH (acidity) of less than 5.5 and cause the demineralization of tooth enamel. [4] Teeth can also be damaged vomiting frequently because stomach acids and enzymes cause enamel erosion contact with the teeth and expose the underlying dentin.

Bacteria
Hundreds of types of bacteria live in the mouth and digestive tract. Bacteria are nourished by the food we eat, but generally do not cause disease and are called “normal flora”. Bacteria in the mouth produced dextran , a sticky polysaccharide in combination with food particles and salivary proteins form a smooth film called dental plaque. These deposits eventually harden into tartar.

The salivarious Streptococcus and Streptococcus mutans are examples of bacteria found in the mouth. Although these bacteria do not cause disease, Streptococcus mutans converts sugars to lactic acid is strong enough to dissolve tooth enamel and start tooth decay if left in contact with the teeth for some time.

Dental plaque contains anaerobic organisms that multiply in the absence of air and living between the teeth and under gums. Porphyromonas gingivalis is an organism that produces enzymes and toxins which cause gum disease characterized by red, swollen gums that bleed easily. Untreated, gingivitis can destroy the supporting structures of teeth.

Dental Caries
Tooth decay often starts with an opaque white spot on the surface of a tooth. The spot shows a location where bacterial acids have demineralized enamel. If erosion continues minerals, the enamel and dentin are destroyed, and it is a cavity in the tooth. A bacterial infection that reaches the pulp can cause severe tooth pain. Saliva helps neutralize some acids produced by oral bacteria, but once the board has been formed, the acids can not be neutralized by saliva, diluted with water, or eating fibrous foods eliminated.

How to Brush
toothbrushes are used to clean teeth and stimulate gums. People who wear braces should brush after eating any food. Brushing twice a day with toothpaste, especially after breakfast and before bedtime, helps reduce dental plaque formation. Toothpaste contains abrasives, surfactants, and acid-neutralizing chemicals that clean the teeth gently. Some toothpastes and fluoride toothpastes also have teeth that hardens when used in moderation. Overuse of fluoride during tooth development can result in discoloration of enamel and mottled teeth. This condition is called dental fluorosis . Use only a small amount of toothpaste (about the size of a pea), and avoid swallowing the toothpaste and other oral hygiene products. After brushing, spit out the toothpaste and Rinse mouth with water.

Dentists recommend brushing the surface of each tooth with a circular motion using a toothbrush with soft bristles will not scratch or irritate the gums teeth. Brush only a small group of teeth at once, and continue gradually throughout the mouth. Be careful to brush the chewing surfaces of molars and also internal and external surfaces of all teeth. It is important to maintain a circular or elliptical motion because motions parallel to the gums cause erosion of the enamel and expose the dentine in the tooth root. Cause enamel erosion teeth become too sensitive to hot and cold liquids.

Dental Floss
Dental floss is a thread with wax or no wax is used to clean plaque and food deposits between teeth or under the gums where toothbrushes can not reach. The use of dental floss is as important as brushing. People with narrow interdental spaces generally prefer waxed floss because it slides easily between teeth than unwaxed floss. Dental floss is used by wrapping a length of 30 to 50 cm between the index fingers of both hands, and placed carefully between each pair of teeth with a gentle sawing motion to reciprocating interdental cleaning all surfaces.

Brush before flossing
Some periodontists recommend brushing your teeth before you floss, while others prefer to brush teeth after flossing. Taking into consideration that flossing may carry bacteria and food particles under the gum, it’s probably better to brush your teeth before to reduce the food particles and bacteria that can be transferred between the teeth and gums. The argument for flossing before brushing is based on the idea that fluoride in toothpaste can only strengthen teeth by contacting the enamel. The plaque between teeth can not be removed by brushing. Removing plaque with silk enamel exposed to the beneficial effect of fluoride in toothpaste. The most important thing is to use dental floss to keep teeth clean. You can prevent the transmission of bacteria under the gum using an antiseptic mouthwash before flossing.

Mouth Rinses
Mouth rinses are used for cosmetic and therapeutic purposes. Most mouthwashes sold without a prescription used to eliminate bad breath, refresh the mouth with a pleasant taste, and perhaps reduce the bacteria in the mouth. Mouthwashes contain a variety of ingredients, but some contain up to 26 percent alcohol. Mouthwashes containing alcohol can cause a burning sensation in the cheeks, tongue, and gums, and can cause poisoning when ingested. Breath tests used to determine the car driving under the influence of alcohol may be positive after using a mouthwash that contains alcohol.

Tooth Whitening
White teeth are considered an attractive feature of a smile. Therefore, teeth whitening is now a common procedure in general dentistry and cosmetic dentistry. The bleaching agent is usually a gel containing hydrogen peroxide (hydrogen peroxide) or carbamide peroxide. A mouthguard containing the whitening gel is applied to teeth for a few minutes or several hours, depending on the concentration of bleach. Tooth bleaching is generally a safe procedure, but can cause chemical burns if the soft tissues come into contact with the gel. Some people complain of increased sensitivity to temperature after teeth whitening.
