Millions of microorganisms call your mouth home—and while most are friendly, some are not. An invasive procedure like implant surgery can disrupt the mouth's soft tissues and allow disease-causing bacteria to enter the bloodstream.
This isn't necessarily a major concern if your immune system is sound—your body will move quickly to quash any developing infection. But if your body's defense is weak or compromised by other health conditions, an ensuing infection could cause you problems. In the case of a dental implant, a localized infection around it could lead to its failure.
The bone normally grows and adheres to the surface of an implant soon after it's placed, giving it the added strength and durability for which implants are best known. A bacterial infection, though, could impede bone integration and weaken the implant's hold within the jaw.
One way to avoid this is by treating patients at high risk for infection with an antibiotic before the procedure. In one recent study, researchers concluded that patients receiving a 2-gram dose of amoxicillin an hour before implant surgery helped reduce the risk of future implant failure.
But before taking this route, the dentist must first decide whether antibiotic pre-treatment might be more detrimental than beneficial to an individual patient. Antibiotics can cause side effects in certain people ranging from diarrhea to allergic reactions. Healthcare providers must also be prudent with administering antibiotics for the good of society in general—overuse can potentially give rise to antibiotic-resistant bacteria.
A number of healthcare associations highly recommend antibiotic pre-treatment for any dental patient with prosthetic heart valves, a history of infective endocarditis, a heart transplant and similar heart conditions. They also recognize patients with conditions like prosthetic joints, weakened immune systems, diabetics or other serious health problems could also benefit from antibiotic pre-treatment, but leave it to the physician's discretion on whether or not it's appropriate for an individual patient.
If you're planning to undergo implant surgery or a similar procedure and are concerned about infection, speak with your dentist about whether you would qualify and benefit from antibiotic pre-treatment. If appropriate, taking an antibiotic beforehand could minimize your infection risk.

Losing a tooth can be traumatic, but a dental implant can dramatically turn that experience around. Providing functionality, life-like appearance and durability, implants stand out as the premier restoration for lost teeth.
For adults, that is. An older child or teenager with a missing tooth may need to wait a few more years for an implant. The reason: jaw development. A person's jaws, particular the upper jaw, continue to grow with most growth completed by early adulthood. Natural teeth with their periodontal attachments develop right alongside the jaw.
But because an implant attaches directly to the jawbone, its position is fixed: it won't change as the jaw grows and may gradually appear to sink below the gum line. That's why we wait to place an implant until most of jaw maturity has occurred after full jaw maturity. For females, we try to wait until 20 years of age and for males, usually 21 years of age. These are guidelines as some people mature faster and some slower, so a discussion with your dentist or surgeon is necessary to make an educated decision.
While we wait, we can install a temporary replacement for a child's or teenager's lost tooth, usually a partial denture or fixed modified ("Maryland") bridge. The latter affixes a prosthetic (false) tooth in the missing tooth space by attaching it to the back of natural teeth on either side with bonded dental material. It differs from a traditional bridge in that these supporting teeth aren't permanently altered and crowned to support the bridge.
During the time before implants we should understand that the area where the implant will be placed will undergo some bone deterioration, a common consequence of missing teeth. Forces generated as we chew travel through the teeth to stimulate renewing bone growth all along the jawbone. But with a lost tooth the chewing stimulation ceases at that part of the bone, slowing the growth rate and leading to gradual bone loss.
Fortunately, the titanium posts of dental implants stimulate bone growth as bone cells naturally grow and adhere to their surfaces. Before then, though, if the bone volume is diminished, we may need to graft bone material to stimulate bone growth that will enlarge the jaw bone enough for an implant to be placed.
It usually isn't a question of "if" but "when" we can provide your child with an implant for their missing tooth. In the meantime, we can prepare for that day with a temporary restoration.

How much do you know about dental implants? Test yourself with this quiz.
- Earliest recorded attempts at using dental implants were from
- Medieval England
- The ancient Mayans
- U.S.A. in the 1950s
- Dental implants are called endosseous. What does this mean?
- They fuse with the bone
- They are inside the mouth
- They are not real teeth
- What are most dental implants made of?
- What part of the tooth does an implant replace?
- The implant is the root replacement
- The implant is the root plus the crown
- The implant is the crown
- What is the success rate of dental implants?
- 50 percent or less
- 75 percent
- 95 percent or more
- What could cause an implant to fail?
- Smoking or drug use
- Poor bone quality and quantity at the implant site
- Both of the above
- What is a tooth's emergence profile?
- The implant and crown's shape as it emerges from beneath the gum line
- A measure of the urgency of the tooth replacement
- A measure of the time it takes for you to be able to chew on the new implant
- What are some of the factors that go into the aesthetics of designing the crown?
- Choice of materials
- Color matching
- Both of the above
- b. The concept of dental implants goes back to the Mayan civilization in 600 AD.
- a. The word endosseous (from endo meaning within and osseo meaning bone) refers to the implant's ability to fuse with or integrate with the bone in which it is placed.
- b. Most implants are made of a titanium alloy, a metallic substance that is not rejected by the body and is able to fuse with the bone.
- a. The term “implant” refers to the root replacement, which is anchored in the gum and bone. A crown is put around the implant where it emerges from the gumline.
- c. The majority of studies have shown long term success rates of over 95 percent.
- c. Factors that could cause an implant to fail include general health concerns such as smoking and drug use, osteoporosis, or a compromised immune system; poor bone quality or quantity; and poor maintenance such as lack of proper brushing and flossing.
- a. The emergence profile has a lot to do with the implant's natural appearance. It involves the way the crown, which attaches to the implant, seemingly emerges through the gum tissue like a natural tooth.
- c. Choices such as materials, color, and position can be worked out in the design of a customized temporary crown, which acts as a template or blueprint for a final crown.
