Yes. Even if you don’t have any symptoms, you can still have dental health problems that only a dentist can diagnose. Regular dental visits will also help prevent problems from developing. Continuity of care is an important part of any health plan and dental health is no exception. Keeping your mouth healthy is an essential piece of your overall health. It’s also important to keep your dentist informed of any changes in your overall health since many medical conditions can affect your dental health too.

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.

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.

The American Dental Association offers these suggestions in finding a dentist:

• Visit ADA Find-a-Dentist to search dentists in your area. 
• Ask family, friends, neighbors or co-workers for recommendations. 
• Ask your family physician or local pharmacist.
• If you're moving, your current dentist may be able to make a recommendation.
• Call or write your state dental society.

You may want to call or visit more than one dentist before making your decision. Dental care is a very personalized service that requires a good relationship between the dentist and the patient. During your first visit, you should be able to determine if this is the right dentist for you.

Consider the following:

• Is the appointment schedule convenient for you?
• Is the office easy to get to from your home or job?
• Does the office appear to be clean, neat and orderly?
• Was your medical and dental history recorded and placed in a permanent file?
• Does the dentist explain techniques that will help you prevent dental health problems? Is dental health instruction provided?
• Are special arrangements made for handling emergencies outside of office hours? (Most dentists make arrangements with a colleague or emergency referral service if they are unable to tend to emergencies.)
• Is information provided about fees and payment plans before treatment is scheduled?
• Is your dentist a member of the ADA? All ADA member dentists voluntarily agree to abide by the high ethical standards reflected in the member code of conduct. You and your dentist are partners in maintaining your oral health. Take time to ask questions and take notes if that will help you remember your dentist's advice.

If you’re looking to find a dentist you may notice that while most are listed with a “DDS”, some may be listed as “DMD”. They both mean the same thing—your dentist graduated from an accredited dental school. The DDS (Doctor of Dental Surgery) and DMD (Doctor of Dental Medicine) are the same degrees. Dentists who have a DMD or DDS have the same education. The level of education and clinical training required to earn a dental degree, and the high academic standards of dental schools are on par with those of medical schools. Upon completion of their training, dentists must pass both a rigorous national written exam and a state or regional clinical licensing exam in order to practice. In order to keep their licenses, they must meet continuing education requirements for the remainder of their careers so that they may stay up to date on the latest scientific and clinical developments.

Here are some tips to help you take care of your smile:

• Healthy habits. Brushing twice a day for two minutes and flossing daily are essential for everyone, no matter how unique your mouth is. It’s the best way to fight tooth decay and gum disease.
• Build a relationship. Continuity of care is an important part of any health plan and dental health is no exception. When your dentist sees you regularly, he or she is in a good position to catch oral problems early. For instance, catching gum disease when it’s still reversible, or cavities when they are small and are more easily treated.
• Maintain. Keeping your mouth healthy is an essential piece of your overall health. It’s important to keep your dentist informed of any changes in your overall health as well.
• Talk about it! Only your dentist can determine what the best treatment plan is for you. Have questions about your oral health or certain dental procedures? Start a conversation. Ask your dentist to explain step-by-step. Dentists love having satisfied, healthy patients.

Exposure to all sources of radiation -- including the sun, minerals in the soil, appliances in your home, and dental X-rays -- can damage the body's tissues and cells and lead to the development of cancer. Fortunately, the dose of radiation you are exposed to during the taking of X-rays is extremely small.

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.

Sealants are a thin, plastic coating that is painted on the chewing surfaces of teeth -- usually the back teeth (the premolars, and molars) -- to prevent tooth decay. The painted on liquid sealant quickly bonds into the depressions and groves of the teeth, forming a protective shield over the enamel of each tooth.

Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in. In this way, the dental sealants can protect the teeth through the cavity-prone years of ages 6 to 14. However, adults without decay or fillings in their molars can also benefit from sealants.

Sealants can protect the teeth from decay for many years, but they need to be checked for chipping or wear at regular dental check-ups.

Drill-less dentistry, also called air abrasion and microabrasion, is being offered by some dentists. Air abrasion can be used to remove some tooth decay, to remove some old composite restorations, to prepare a tooth surface for bonding or sealants, and to remove superficial stains and discolorations. The air abrasion instrument works like a mini sandblaster to spray away the decay, stain, or to prepare the tooth surface for bonding or sealant application. With air abrasion, a fine stream of particles is aimed at the tooth surface. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air or a gas that runs through the dental handpiece. Small particles of decay, stain, etc., on the tooth surface are removed as the stream of particles strikes them. The remnant particles are then "suctioned" away.

Over the past several years, concerns have been raised about silver-colored fillings, otherwise called amalgams. Because amalgams contain the toxic substance mercury, some people think that they are responsible for causing a number of diseases, including autism spectrum disorders, Alzheimer's disease, and multiple sclerosis.

The American Dental Association (ADA), the FDA, and numerous public health agencies say amalgams are safe, and that any link between mercury-based fillings and disease is unfounded. The cause of ASD, Alzheimer's disease, and multiple sclerosis remains unknown. Additionally, there is no solid, scientific evidence to back up the claim that if a person has amalgam fillings removed, he or she will be cured of these or any other diseases.

In March of 2002, the FDA reconfirmed the safety of amalgams. Although amalgams do contain mercury, when they are mixed with other metals, such as silver, copper, tin, and zinc, they form a stable alloy that dentists have used for more than 100 years to fill and preserve hundreds of millions of decayed teeth. The National Institutes of Health conducted several large-scale studies that concluded in 2006 that amalgam fillings were safe.

In addition, there has been concern over the release of a small amount of mercury vapor from these fillings, but according to the ADA, there is no scientific evidence that this small amount results in adverse health effects.

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.

Several different options are available to change the shape of teeth, make teeth look longer, close spaces between teeth or repair chipped or cracked teeth. Among the options are bonding, crowns, veneers, and recontouring.

• Dental bonding is a procedure in which a tooth-colored resin material (a durable plastic material) is applied to the tooth surface and hardened with a special light, which ultimately "bonds" the material to the tooth.
• Dental crowns are tooth-shaped "caps" that are placed over teeth. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
• Veneers (also sometimes called porcelain veneers or dental porcelain laminates) are wafer-thin, custom-made shells of tooth-colored materials that are designed to cover the front surface of teeth. These shells are bonded to the front of the teeth.
• Recontouring or reshaping of the teeth (also called odontoplasty, enameloplasty, stripping, or slenderizing) is a procedure in which small amounts of tooth enamel are removed to change a tooth's length, shape or surface.

Each of these options differ with regard to cost, durability, "chair time" necessary to complete the procedure, stain resistant qualities, and best cosmetic approach to resolving a specific problem. Talk to your dentist to see if one is right for you.

If you fear going to the dentist, you are not alone. Between 9% and 15% of Americans state they avoid going to the dentist because of anxiety or fear. The first thing you should do is talk with your dentist. In fact, if your dentist doesn't take your fear seriously, find another dentist. The key to coping with dental anxiety is to discuss your fears with your dentist. Once your dentist knows what your fears are, he or she will be better able to work with you to determine the best ways to make you less anxious and more comfortable.

The good news is that today there are a number of strategies that can be used to help reduce fear, anxiety, and pain. These strategies include use of medications (to either numb the treatment area or sedatives or anesthesia to help you relax), use of lasers instead of the traditional drill for removing decay, application of a variety of mind/body pain and anxiety-reducing techniques (such as guided imagery, biofeedback, deep breathing, acupuncture, and other mental health therapies), and perhaps even visits to a dentophobia clinic or a support group.

First, when purchasing a toothpaste for you or your child, select one that contains fluoride. Fluoride-containing toothpastes have been shown to prevent cavities. However, one word of caution:Use only a very small amount for children under age 6 (the size of their fingernail). This is because young children swallow toothpaste, and swallowing too much fluoride can lead to tooth discoloration in permanent teeth.

It is also wise to select a product approved by the American Dental Association. The ADA's Seal of Acceptance means that the product has met ADA criteria for safety and effectiveness and that packaging and advertising claims are scientifically supported. Some manufacturers choose not to seek the ADA's Seal of Acceptance. Although these products may be safe and effective, these products' performance have not been evaluated or endorsed by the ADA.

Next, when considering other properties of toothpaste -- such as whitening toothpastes, tartar-control, gum care, desensitizing, etc. -- the best advice for selecting among these products may be to simply ask your dental hygienist or dentist what the greatest concerns are for your mouth at this time. After consulting with your dentist or hygienist about your oral health's greatest needs, look for products within that category (for example, within the tartar control brands or within the desensitizing toothpaste brands) that have received the ADA Seal of Acceptance.

Finally, some degree of personal preference comes into play. Choose the toothpaste that tastes and feels best. Gel or paste, wintergreen or spearmint all work alike. If you find that certain ingredients are irritating to your teeth, cheeks or lips, or if your teeth have become more sensitive, or if your mouth is irritated after brushing, try changing toothpastes. If the problem continues, see your dentist.

Yes. Thousands of dentists across the country offer their services at reduced fees through dental society-sponsored assistance programs. Since aid varies from one community to another, call your local dental society for information about where you can find the nearest assistance programs and low-cost care locations (such as public health clinics and dental school clinics).

Check your local phone book or the Internet for your local dental society (for example, the Georgia Dental Society, Georgia Dental Association, or search by your county or region).

The American Dental Association's website provides links to state dental associations local societies, and state dental schools. Ask your dentist or call your local social service organization for assistance in locating these types of services in your community.

The American Dental Association offers these suggestions:

• Ask family, friends, neighbors, or co-workers for their recommendations.
• Ask your family doctor or local pharmacist.
• If you're moving, your current dentist may be able to make a recommendation.
• Call or write your local or state dental society. Your local and state dental societies also may be listed in the telephone directory under "dentists" or "associations." The ADA provides a list of local and state dental societies on its website.
• Visit more than one dentist before selecting one you feel you can build a good long-term relationship with.
