Advances in dentistry over the years have lead to the low radiation levels emitted by dental X-rays. Some of the improvements are new digital X-ray machines that limit the radiation beam to the small area being X-rayed, higher speed X-ray films that require shorter exposure time compared with older film speeds to get the same results, and the use of film holders that keep the film in place in the mouth (which prevents the film from slipping and the need for repeat X-rays and additional radiation exposure). Also, the use of lead-lined, full-body aprons protects the body from stray radiation (though this is almost nonexistent with the modern dental X-ray machines.) In addition, federal law requires that X-ray machines be checked for accuracy and safety every two years, with some states requiring more frequent checks.
You should be brushing your teeth for two minutes, twice a day with fluoride toothpaste. Choose a soft-bristled brush that fits your mouth and place the toothbrush at a 45-degree angle to the gums. Gently move the brush back and forth in short, tooth-wide strokes. Brush the outer surfaces, the inner surfaces, and the chewing surfaces of the teeth. To clean the inside surfaces of the front teeth, tilt the brush vertically and make several up-and-down strokes. Brush your tongue to remove bacteria and keep your breath fresh.
Fluoride helps prevent cavities in children and adults by making teeth more resistant to the acid attacks that cause cavities. When you brush your teeth with fluoride toothpaste, use other fluoride dental products and drink water with fluoride you are preventing cavities and strengthening your teeth’s enamel. Fluoride, also called nature’s cavity fighter, occurs naturally in varying amounts in water sources such as rivers, lakes and even the oceans. Fluoride was first added to public water systems in 1945 and its use has grown significantly over the past 70 years. The most recent data indicates 74.6% of the U.S. population served by public water systems receive the benefits of fluoridated water. Studies have consistently shown that optimizing the level of fluoride in community water supplies is safe and effective in preventing dental decay in both children and adults by at least 25%. Simply by drinking water, people benefit from fluoride's cavity protection whether they are at home, work or school.
All toothpastes help remove surface stains through the action of mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening products contain hydrogen peroxide (a bleaching substance) that helps remove stains on the tooth surface as well as stains deep in the tooth. None of the home use whitening toothpastes can come even close to producing the bleaching effect you get from your dentist's office through chair-side bleaching or power bleaching. Whitening toothpastes can lighten your tooth's color by about one shade. In contrast, light-activated whitening conducted in your dentist's office can make your teeth three to eight shades lighter. .
There is no one-size-fits-all dental treatment. Some people need to visit the dentist once or twice a year; others may need more visits. You are a unique individual, with a unique smile and unique needs when it comes to keeping your smile healthy. Talk to your dentist about how often you need to schedule visits.
The dentist or hygienist will ask about your recent medical history, examine your mouth and decide whether or not you need x-rays. Depending on your treatment plan, the hygienist may use a special dental instruments to check your gums for gum disease. Your dentist will evaluate your overall dental health and conduct an oral cancer screening by holding your tongue with gauze, checking it and your whole mouth, then feeling your jaw and neck.
For a knocked-out permanent or adult tooth, keep it moist at all times. If you can, try placing the tooth back in the socket without touching the root. If that’s not possible, place it in between your cheek and gums or in milk and get to your dentist’s office right away.
For toothaches, rinse your mouth with warm water to clean it out. Gently use dental floss to remove any food caught between your teeth. Do not put aspirin on your aching tooth or gums; it may burn the gum tissue. If the pain persists, contact your dentist.
