Twenty-first Century techniques can create a replacement for a missing or damaged tooth that looks exactly like a natural tooth and actually fuses with the bone of your jaw. How does this amazing technology work? Test your knowledge on these questions.
What is a dental implant?
A dental implant is actually a replacement for the root of a tooth. In the natural tooth, the root is the part of the tooth below the gum line that is suspended in the bone by ligaments that attach the root to the bone. An implant is a root like substitute that is directly attached to the bone by a process referred to as osteointegration. An implant crown is then attached to the implant and is the visible part that we see above the gum tissues.
What is a modern dental implant made of?
Most are made of titanium. This metal is not rejected by the body and in fact fuses with the bone in which the implant is anchored, making it extremely stable.
How long do implants last?
A successful implant can last a lifetime. Factors that can affect an implant's success are smoking, certain drugs, osteoporosis, a history of radiation treatment, or a compromised immune system. We will evaluate all your conditions of dental and general health before deciding on an implant for you.
What makes the crown look like a real tooth?
The new crown looks real if it matches the shape and color of adjacent natural teeth. Its appearance also depends on what we as dentists refer to as the emergence profile (the way the crown seems to emerge from the gum tissue).
What is the function of a temporary crown?
A customized temporary crown can allow details of color, shape, and emergence profile to be worked out during this “temporary” phase of treatment. It can also test whether the tooth will function correctly for speech, biting and chewing. After these details are worked out, the temporary crown can be used as a blueprint for the permanent one.

Dental implants are replacements for missing teeth. They are very stable and can be made to look as good as or better than the teeth they replace. How do we do it? Here are seven frequently asked questions.
What are the parts of a dental implant?
The implant consists of a root, usually made of a titanium alloy, which extends below the gum tissue into the bone; and a crown, which emerges from the gum and resembles the crown of the original tooth.
Why is a dental implant so stable?
Titanium has a property of fusing with the bone of the jaw, so that it actually becomes part of the bony structure. The new implant's stability depends on having the needed volume of bone and gum tissue in the right position to anchor the implant.
How can you make sure I have enough bone?
When a tooth is lost, the bone in which it was anchored will resorb or melt away if care is not taken. It is important to minimize trauma during tooth removal to preserve bone tissue. If tissue has been lost it can be built up by bone grafting techniques.
What factors make a crown on an implant look real?
How real the crown looks depends on its shape, particularly as it emerges through the gum tissues, its color and its position relative to the teeth around it.
What is the emergence profile?
This term refers to the way the crown emerges through the gum tissue. It involves both the shape of the implant and how far it is placed into the gum and bone tissues.
How do you match the color of the crown?
We analyze your tooth color using shade guides and/or photography to provide the dental lab with as much information as possible to create the best color match. This is part of the artistry of reconstructive dentistry.
How will my gums look with my dental implant in place?
When people use the word “gums” they are often referring to the small pink triangles of tissue that fill in the spaces between teeth, called “papillae.” An implant must be placed at the correct distance from adjacent teeth and at the correct depth below the gum tissue for natural looking papillae to form.
You can see that success in matching of color, shape, and location of an implant is not simple and depends on the skill, artistry, and experience of your dental team.
A number of factors can lead to dental caries (tooth decay). To find out if you are at high risk, ask yourself these questions.
Is plaque visible in my mouth?
Dental plaque is a whitish film of bacteria that collects on your teeth. If it is clearly visible, it means that there is a lot of it. Among the bacteria in the plaque are those that produce tooth decay, particularly in an acidic environment. (A normal mouth is neutral, measured on the pH scale, midway between the extreme acidic and basic ends of the scale.)
Do I have a dry mouth?
Saliva protects your teeth against decay by neutralizing an acidic environment and adding minerals back to the outer surface of enamel of your teeth, so reduced saliva is a high risk for caries. Many medications can cause dry mouth as a side effect.
Do I eat a lot of snacks, particularly unhealthy ones?
Frequently eating sugars, refined carbohydrates, and acidic foods promotes the growth of decay-producing bacteria. The more frequently you eat, the longer your teeth are bathed in sugars and acids. Acidic foods not only promote bacterial growth, they also directly cause erosion of the tooth's hard surface by softening and dissolving the minerals in the enamel.
Do I wear retainers, orthodontic appliances, bite guards or night guards?
These appliances are recommended for various conditions, but they tend to restrict the flow of saliva over your teeth, cutting down on the benefits of saliva mentioned above.
Do my teeth have deep pits and fissures?
The shape of your teeth is determined by your heredity. If your teeth grew in with deep grooves (fissures) and pits in them, you are at higher risk for bacterial growth and resulting decay.
Do I have conditions that expose my teeth to acids?
If you have bulimia (a psychological condition in which individuals induce vomiting), or GERD (Gastro-Esophageal Reflux Disease), your teeth may be frequently exposed to stomach acids that can cause severe erosion to your teeth.
Do I already have cavities?
Visible cavities can range from those only visible with laser technology or x-ray examination to those a dentist can see with a naked eye. If you already have small cavities, you are at high risk for developing more.
Do I have white spots on my teeth?
White spots are often the first sign of decay in a tooth's enamel. At this point, the condition is often reversible with fluorides.
Have I had a cavity within the last three years?
Recent cavities point to a high risk of more cavities in the future, unless conditions in your mouth have significantly changed.
If you have any of these indications of high risk, contact us today and ask us for suggestions for changing the conditions in your mouth. You can also learn more by reading the Dear Doctor magazine article “Tooth Decay.”
