What is oral hygiene Definition?

The purpose of oral hygiene is to prevent the buildup of plaque, the sticky film of bacteria and food that forms on the teeth. Plaque adheres to the crevices and fissures of the teeth and generates acids that, when not removed on a regular basis, slowly eat away, or decay, the protective enamel surface of the teeth, causing holes (cavities) to form. Plaque also irritates gums and can lead to gum disease, , and tooth loss. Brushing and flossing removes plaque from teeth, and antiseptic mouthwashes kill some of the bacteria that help form plaque. Fluoride, found in toothpaste, drinking water, or dental treatments, also helps to protect teeth by binding with enamel to make it stronger. In addition to such daily oral care, regular visits to the dentist promote oral health. Preventative services that the dentist can perform include fluoride treatments, sealant application, and scaling (scraping off the hardened plaque, called tartar). The dentist can also perform such diagnostic services as x-ray imaging and such treatments as filling cavities.

Description

The Centers for Disease Control and Prevention report that dental caries are perhaps the most prevalent of infectious diseases in children. More than 40 percent of all children have cavities by the time they reach kindergarten. It is, therefore, imperative that all parents learn the importance of early oral care and that they teach their children proper oral hygiene.

Good oral hygiene should start at the very beginning of a child's life. Even before his or her first teeth emerge, certain factors can affect their future appearance and health. Pregnant and nursing mothers should be careful about using medications, as some, like the antibiotic tetracycline, can cause tooth discoloration. Even before infants have teeth, they have special oral hygiene needs about which all parents should be aware. These include making certain the child receives adequate fluoride and guarding against baby bottle decay.

Fluoride in infancy

Fluoride is beneficial for babies even before their teeth erupt. It makes the tooth enamel stronger as the teeth are developing. In most municipal water supplies, the correct amount of fluoride is added for proper tooth development. If the water supply does not contain enough fluoride or if bottled water is used for drinking and cooking, the doctor or dentist should be informed. They may prescribe fluoride supplements for the baby.

Baby bottle decay

Baby bottle decay is caused by recurring exposure over time to sugary liquids. These include milk, formula, and fruit juices. These liquids pool for prolonged periods of time as the child sleeps. This exposure can lead to cavities forming, especially in the upper and lower front teeth. For this reason, children should not be allowed to fall asleep with a bottle of juice or milk in their mouths. An alternative is to give the child a bottle filled with water or a pacifier recommended by the dentist. Even breast-fed children are at risk. They should have their gums and teeth wiped with a clean, damp washcloth or gauze pad following each feeding.

Baby teeth, also known as primary teeth, are just as important as permanent teeth. They help the child to bite and chew food, help them speak correctly, save space for the child's permanent teeth, and help guide the permanent teeth into place. That is why it is so important to initiate a program of good oral hygiene for children early on.

Brushing

Once a baby has four teeth in a row, either on top or on the bottom, parents should begin using a toothbrush two times a day. When choosing a toothbrush, make sure the bristles are soft, polished, and made of nylon. Parents should administer only a pea-size amount of fluoride toothpaste that is made especially for children. Children tend to swallow, instead of spit out, toothpaste. If the child does not like the flavor of the toothpaste, using water alone is acceptable. Parents should also continue to wipe the toothless gum areas with a washcloth or gauze.

As the child gets older, parents should demonstrate proper brushing techniques. These include brushing the inside surface of each tooth first, where plaque tends to accumulate most. Then they should clean the outer surfaces of each tooth, angling the brush along the outer gum line. Next, they should brush the chewing surface of each tooth, then using the tip of the brush, clean behind each front tooth. They should use a gentle, back and forth motion when brushing and finish by brushing the tongue.

Children will, at some point, decide they would like to try brushing their teeth themselves. This is fine and should be encouraged, but parents should remain in charge of keeping children's teeth clean until they are between six to eight years old. Children do not have the dexterity or coordination to perform brushing well until this time. Even then, it is important that parents inspect their children's teeth each time they brush. They should

Good oral hygiene remains important as children grow into . In fact, adolescence can often be a time when cavities and periodontal disease happen more frequently. This higher rate is usually caused by an increased intake of junk food and sugary foods such as soft drinks, as well as inattention to oral hygiene procedures. Add to that the fact that many older children and teens wear braces, making the cleaning of teeth even more challenging. Parents should talk to their children about how important good oral hygiene is in preventing not only cavities, but teeth stains, bad breath, and an assortment of other dental problems.
