Despite improvements in dental care, millions of Americans suffer tooth loss - mostly due to tooth decay, gingivitis (gum disease), or injury. For many years, the only treatment options available for people with missing teeth were bridges and dentures. But, today, dental implants are available.

What Are Dental Implants?

Dental implants are replacement tooth roots. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth.

What Are the Advantages of Dental Implants?

There are many advantages to dental implants, including:

• Improved appearance. Dental implants look and feel like your own teeth. And because they are designed to fuse with bone, they become permanent.
• Improved speech. With poor-fitting dentures, the teeth can slip within the mouth causing you to mumble or slur your words. Dental implants allow you to speak without the worry that your teeth might slip.
• Improved comfort. Because they become part of you, implants eliminate the discomfort of removable dentures.
• Easier eating. Sliding dentures can make chewing difficult. Dental implants function like your own teeth, allowing you to eat your favorite foods with confidence and without pain.
• Improved self-esteem. Dental implants can give you back your smile and help you feel better about yourself.
• Improved oral health. Dental implants don't require reducing other teeth, as a tooth-supported bridge does. Because nearby teeth are not altered to support the implant, more of your own teeth are left intact, improving your long-term oral health. Individual implants also allow easier access between teeth, improving oral hygiene.
• Durability. Implants are very durable and will last many years. With good care, many implants last a lifetime.
• Convenience. Removable dentures are just that; removable. Dental implants eliminate the embarrassing inconvenience of removing your dentures, as well as the need for messy adhesives to keep your dentures in place.

How Successful Are Dental Implants?

Success rates of dental implants vary, depending on where in the jaw the implants are placed but, in general, dental implants have a success rate of up to 98%. With proper care (see below), implants can last a lifetime.

Can Anyone Get Dental Implants?

In most cases, anyone healthy enough to undergo a routine dental extraction or oral surgery can be considered for a dental implant. Patients should have healthy gums and enough bone to hold the implant. They also must be committed to good oral hygiene and regular dental visits. Heavy smokers, people suffering from uncontrolled chronic disorders - such as diabetes or heart disease - or patients who have had radiation therapy to the head/neck area need to be evaluated on an individual basis.

The American Academy of Pediatric Dentistry (AAP) announced new oral health guidelines for pregnant women in 2009 tailored to assist them in maintaining healthy teeth and gums during their pregnancy and into the early stages of motherhood. Why is oral health care important during pregnancy? Mothers with gum disease have a higher instance of preterm birth, a potentially serious pregnancy complication that may cause health concerns for their infant, typically due to a low birth weight.

Pregnancy gingivitis is a common form of gum disease known to develop in almost half of all pregnant women likely due to the change in hormones. When kept at-bay, pregnancy gingivitis generally ends shortly after the birth of the child, although it should be monitored by a dentist periodically during pregnancy in order to prevent this form of gingivitis from progressing into more serious periodontitis, an advanced and irreversible form of gum disease that has been linked with preterm birth. Pregnant mothers with periodontal disease are seven times more likely to go into preterm labor. Prostaglandin, a chemical found in oral bacteria, may induce labor. And high levels of prostaglandin has been found in the mouths of women with severe cases of periodontal disease.

The following guidelines were developed by the AAP in response to the growing concern surrounding oral health during pregnancy:

• Oral Health Education - Counseling and early intervention by healthcare providers such as physicians, nurses, and dentists to provide expectant mothers with the tools and resources necessary to understand the importance of oral health care during pregnancy.
• Oral Hygiene - Removing the bacterial plaque, which researchers have connected to preterm birth and low birth-weight babies, is essential. Using the correct brushing and flossing methods greatly increase the amount of plaque that is removed from the teeth and gums.
• Fluoride - The American Dental Association recommends the use of toothpaste with fluoride by persons over the age of six. Echoing their sentiment, the AAP oral health guidelines advise the continued use of fluoridated toothpaste during pregnancy, and recommends the use of an over-the-counter alcohol-free fluoride rinse to help reduce the amount of plaque in the mouth.
• Nutrition - Educating expectant mothers about proper diet and nutrition during pregnancy will limit unnecessary sugar intake and in turn, prevent plaque build up.
• Treating Existing Tooth Decay - Expectant mothers are encouraged to have existing tooth decay treated during their pregnancy, which experts believe is a completely safe practice during pregnancy. Restoring decayed teeth will help achieve oral health by removing the bacteria associated with tooth decay.
• Transmission of Bacteria - Expectant mothers are discouraged from sharing food and utensils in order to prevent the transmission of the bacteria known to cause tooth decay.
• Use of Xylitol Gum - Expectant mothers are encouraged to chew xylitol gum (four times a day) as research suggests that chewing this gum may decrease the rate of tooth decay in children.

Talk to Your Dentist

If you are pregnant or are considering pregnancy, discuss any concerns you may have with your dentist. Women who are thinking about becoming pregnant may want to consider their oral health before becoming pregnant as research suggests that treating existing gum disease in pregnant women does not reduce the instance of preterm birth. Despite this fact, experts insist that regular oral health care should continue throughout pregnancy.

Frequently asked questions: dental fillings

Are dental amalgams safe? Is it possible to have an allergic reaction to amalgam? Is it true that dental amalgams have been banned in other countries? Is there a filling material that matches tooth color? If my tooth doesn't hurt and my filling is still in place, why would the filling need to be replaced? Read this interesting and informative discussion from the American Dental Association.

FDA consumer update: dental amalgams

The Food and Drug Administration and other organizations of the U.S. Public Health Service (USPHS) continue to investigate the safety of amalgams used in dental restorations (fillings). However, no valid scientific evidence has shown that amalgams cause harm to patients with dental restorations, except in rare cases of allergic reactions.

ATSDR - public health statements: mercury

The Centers for Disease Control and Prevention offers some scientific background on mercury (contained within silver-colored fillings), and whether it believes the substance presents any health hazards.

Analysis reveals significant drop in children's tooth decay

Children have significantly less tooth decay in their primary (baby) and permanent teeth today than they did in the early 1970s, according to the Journal of the American Dental Association (JADA). The analysis reveals that among children between the ages of six and 18 years, the percentage of decayed permanent teeth decreased by 57.2 percent over a 20-year period. In addition, children between the ages of two and 10 years experienced a drop of nearly 40 percent in diseased or decayed primary teeth.

Alternative Materials

Advances in modern dental materials and techniques increasingly offer new ways to create more pleasing, natural-looking smiles. Researchers are continuing their often decades-long work developing esthetic materials, such as ceramic and plastic compounds that mimic the appearance of natural teeth. As a result, dentists and patients today have several choices when it comes to selecting materials used to repair missing, worn, damaged or decayed teeth.

The advent of these new materials has not eliminated the usefulness of more traditional dental restoratives, which include gold, base metal alloys and dental amalgam. The strength and durability of traditional dental materials continue to make them useful for situations where restored teeth must withstand extreme forces that result from chewing, such as in the back of the mouth.

Alternatives to amalgam, such as cast gold restorations, porcelain, and composite resins are more expensive. Gold and porcelain restorations take longer to make and can require two appointments. Composite resins, or white fillings, are esthetically appealing, but require a longer time to place.

Here's a look at some of the more common kinds of alternatives to silver amalgam:

• Composite fillings - Composite fillings are a mixture of acrylic resin and finely ground glasslike particles that produce a tooth-colored restoration. Composite fillings provide good durability and resistance to fracture in small-to-mid size restorations that need to withstand moderate chewing pressure. Less tooth structure is removed when the dentist prepares the tooth, and this may result in a smaller filling than that of an amalgam. Composites can also be "bonded" or adhesively held in a cavity, often allowing the dentist to make a more conservative repair to the tooth. In teeth where chewing loads are high, composite fillings are less resistant to wear than silver amalgams. It also takes longer to place a composite filling.
• Ionomers - Glass ionomers are tooth-colored materials made of a mixture of acrylic acids and fine glass powders that are used to fill cavities, particularly those on the root surfaces of teeth. Glass ionomers can release a small amount of fluoride that help patients who are at high risk for decay. Glass ionomers are primarily used as small fillings in areas that need not withstand heavy chewing pressure. Because they have a low resistance to fracture, glass ionomers are mostly used in small non-load bearing fillings (those between the teeth) or on the roots of teeth. Resin ionomers also are made from glass filler with acrylic acids and acrylic resin. They also are used for non-load bearing fillings (between the teeth) and they have low to moderate resistance to fracture. Ionomers experience high wear when placed on chewing surfaces. Both glass and resin ionomers mimic natural tooth color but lack the natural translucency of enamel. Both types are well tolerated by patients with only rare occurrences of allergic response.
• Porcelain (ceramic) dental materials - All-porcelain (ceramic) dental materials include porcelain, ceramic or glasslike fillings and crowns. They are used as inlays, onlays, crowns and aesthetic veneers. A veneer is a very thin shell of porcelain that can replace or cover part of the enamel of the tooth. All-porcelain (ceramic) restorations are particularly desirable because their color and translucency mimic natural tooth enamel. All-porcelain restorations require a minimum of two visits and possibly more. The restorations are prone to fracture when placed under tension or on impact. Their strength depends on an adequate thickness of porcelain and the ability to be bonded to the underlying tooth. They are highly resistant to wear but the porcelain can quickly wear opposing teeth if the porcelain surface becomes rough.

Sealants

Research has shown that almost everybody has a 95 percent chance of eventually experiencing cavities in the pits and grooves of their teeth.

Sealants were developed in the 1950s and first became available commercially in the early 1970s. The first sealant was accepted by the American Dental Association Council on Dental Therapeutics in 1972. Sealants work by filling in the crevasses on the chewing surfaces of the teeth. This shuts out food particles that could get caught in the teeth, causing cavities. The application is fast and comfortable and can effectively protect teeth for many years. In fact, research has shown that sealants actually stop cavities when placed on top of a slightly decayed tooth by sealing off the supply of nutrients to the bacteria that causes a cavity.

Sealants act as a barrier to prevent bacteria and food from collecting and sitting on the grooves and pits of teeth. Sealants are best suited for permanent first molars, which erupt around the age of 6, and second molars, which erupt around the age of 12.

Sealants are most effective when applied as soon as the tooth has fully come in. Because of this, children derive the greatest benefit from sealants because of the newness of their teeth. Research has shown that more than 65% of all cavities occur in the narrow pits and grooves of a child`s newly erupted teeth because of trapped food particles and bacteria.

Application

Sealant application involves cleaning the surface of the tooth and rinsing the surface to remove all traces of the cleaning agent. An etching solution or gel is applied to the enamel surface of the tooth, including the pits and grooves. After 15 seconds, the solution is thoroughly rinsed away with water. After the site is dried, the sealant material is applied and allowed to harden by using a special curing light.

Sealants normally last about five years. Sealants should always be examined at the child`s regular checkup. Sealants are extremely effective in preventing decay in the chewing surfaces of the back teeth.

Insurance coverage for sealant procedures is increasing, but still minimal. Many dentists expect this trend to change as insurers become more convinced that sealants can help reduce future dental expenses and protect the teeth from more aggressive forms of treatment.

February is Dental Health Month as well as American Heart Month. We would like to educate our patients on the connection between oral health and the heart.

Oral health and its relationship to total health underscore the need to educate consumers about the importance of quality preventive oral health care.

Research has identified periodontal (gum) disease as a risk factor for heart and lung disease, diabetes, premature, low birth weight babies and a number of other conditions. The 2000 Surgeon General's report, Oral Health in America, has called attention to this connection and states that, if left untreated, poor oral health is a "silent X-factor promoting the onset of life-threatening diseases which are responsible for the deaths of millions of Americans each year."

A major disease with an oral health connection is heart disease—the number one killer of men and women—claiming more victims than all forms of cancer and AIDS combined. In 2005, more than 80 million people had one or more forms of cardiovascular disease (CVD); almost 900,000 died in 2004 from CVD.(1) Numerous research studies have shown a connection between heart disease and key bacteria in periodontal disease. While research continues to explore this link, dental hygienists are instrumental in identifying the presence and extent of the periodontal infection and work with patients, both to treat existing periodontal problems and to prevent future complications.
