Dental implants traditionally have a high success rate with numerous studies showing long-term success rates of over 95%. This is just one of the reasons they have been widely accepted as the best method for permanently replacing missing teeth. In fact, over-dentures, which are full dentures supported and stabilized by at least two dental implants, are now considered the standard of care by the American Dental Association (ADA) for people who have lost all of their teeth in one or both jaws. And while they have a high success rate, there are some factors that can compromise the success rates of implants.
These factors are generally divided into three categories: general health concerns, local factors, and maintenance issues.
- General health concerns: Your general health, lifestyle, and habits can play a major role in the success of dental implants. For example, smoking, diabetes, osteoporosis (porous bone) or a compromised immune (resistance) system can all negatively impact implant healing and success. And if you have a history of radiation treatment to your jawbones, you are at a higher risk for complications.
- Local factors: Some examples of local factors that can affect implant success include bone quality and quantity — having sufficient bone in the right place to accurately secure and locate the implants.
- Maintenance issues: While implants are excellent high tech replacements for missing permanent teeth, they do require routine maintenance. This includes daily cleaning and continued professional care. Otherwise, implants are just like any other technically sophisticated devices — they may be susceptible to breakdown.
Periodontal (gum) diseases are sometimes called “silent” because those who have them may not experience painful symptoms. But certain signs point to the existence of these common diseases. If you are experiencing any of the symptoms below, it is time to visit our office so these problems can be treated before they lead to serious infection and loss of teeth.
Gums that bleed during the brushing of teeth. Some people think that gums bleed from brushing too hard. In fact, healthy gum tissues will not bleed with normal brushing. The usual cause of bleeding gums is an accumulation of dental plaque in the areas where your teeth meet your gums. Plaque is a film of bacteria, called a biofilm, which accumulates on your teeth. If you are not brushing and flossing effectively, plaque irritates your gum tissues and causes an inflammation and swelling called gingivitis. This causes your gums to bleed easily on contact with a toothbrush or floss.
Gum tissues that appear red and swollen. If plaque is allowed to accumulate for 24 hours or more, the inflammation in your gum tissues becomes chronic. The continuous presence of bacteria makes it impossible for your body's natural defenses to fight the infection. Chronic inflammation leads to a breakdown of the normal attachment between the teeth and the gums, causing the formation of “pockets.” Inside these pockets the infection continues to attack the tissues that support your teeth. Eventually this can lead to a breakdown of the bone that surrounds your teeth.
Bad breath. Bad breath is another sign of accumulated plaque. The bacteria in plaque may emit gases that have an unpleasant odor.
Gums that are sensitive to hot or cold. Chronic inflammation can also cause the gums to recede, exposing the roots of the teeth in which nerves may be close to the surface, leading to sensitivity to heat and cold.
Teeth that are getting loose, or a painful area in the gums. If you experience these symptoms, the infection has progressed a long way from the “silent” stage. It is time to seek immediate professional help.
If you answered “yes” to any of the above questions, a professional dental examination is in order. With daily removal of plaque by effective brushing and flossing, along with frequent professional cleanings to remove any plaque that you were unable to catch, you will go a long way to preventing periodontal disease. Also, be aware that smoking tends to mask the effects of gum disease. Generally, if you smoke your gums will not bleed when brushing or flossing, nor will they show signs of swelling.

If you see blood when you brush or floss your teeth, it generally indicates a problem with your oral health. You may think you are brushing too hard, but this is not usually why gums bleed. The usual culprit is dental plaque.
Plaque is the sticky, whitish film of bacteria that forms on your teeth every day. If you brush regularly, you probably remove most of it — but some may remain behind and accumulate where your teeth meet your gums, particularly between your teeth. As the bacteria build up, along with by-products of their metabolism (the chemical reactions that maintain their lives), they cause inflammation, called gingivitis, in the adjacent gums.
Bleeding gums are an early symptom of gingivitis. Continuing contact with plaque at the gum line can cause your gum tissue to separate from nearby teeth, creating pockets in which the inflammation becomes even worse. The process leads to periodontal disease (“peri” – meaning around, “odont” – tooth). The increasing infection can eat away the bone that anchors the teeth, leading to possible tooth loss. Periodontal disease is not an uncommon problem. About 90% of the population has bleeding gums at some time or another, and approximately 10% go on to develop periodontal disease.
When you lose bone around your teeth, the gums separate from the tooth and “pockets” form between your teeth and gums. The inflammation and infection may continue within the pockets even if your gums have stopped bleeding when you brush. That's why it is important to have regular dental exams — to check up on and stop periodontal disease before it has a chance to cause serious damage.
There may also be other reasons for bleeding gums that have to do with your general state of health. Women who have elevated levels of hormones caused by birth control pills or pregnancy may experience an increased response to plaque that makes their gums bleed more easily. Increased bleeding in your gums can also be caused by some diseases or as a side effect of some medications.
The most important way to prevent bleeding gums is to learn proper brushing and flossing techniques so that you effectively remove plaque from your teeth on a daily basis. If you are not sure you are using the right techniques, make an appointment and have us demonstrate at your next dental visit.
With all the best intentions, some plaque may remain. Plaque that is allowed to stay on your teeth hardens into a substance called tartar or calculus. This must be removed periodically with a professional cleaning by me or by our hygienist.
With not too much effort, you can ensure that your teeth are clean and plaque free, and your healthy gums no longer bleed.
“Impacted wisdom teeth.” The term alone sounds ominous. What are wisdom teeth, why do they become impacted, what is the best way to treat them? These are questions people often ask.
What are “wisdom teeth” anyway?
Your third molars, located in the very back of your jaws, are your wisdom teeth. Most people have four of them.
Why is their name associated with wisdom?
They usually begin to come in when a person is 17 to 25 years old, a time when he or she can be said to begin to reach an age of wisdom.
Doesn't everyone get wisdom teeth?
While some people have more than four, others have fewer, and some have no wisdom teeth at all. Some people have wisdom teeth that can be seen in x-rays but do not erupt (grow up through their gums) and become visible.
What does “impacted” mean?
In normal usage, the term “impact” means “influence or effect.” In dental vocabulary, it means that a tooth is affecting another tooth or a nearby structure such as gums, nerves or blood vessels. Often an impacted wisdom tooth grows sideways into an adjacent tooth instead of growing upwards to come through the gums normally. This may be caused by a lack of room in your jaw for your third molars.
What kinds of problems can impacted wisdom teeth cause?
A wisdom tooth can impact the gum tissues surrounding nearby molars, leading to infection called “periodontal disease” (from the root words for “around” and “tooth.”) They can also cause root resorption in adjacent teeth, a process by which the tooth’s roots are slowly dissolved and eaten away.
What are the symptoms of impacted wisdom teeth?
Sometimes impacted teeth are asymptomatic — you feel nothing, even though damage is being done to gums and teeth surrounding the wisdom teeth. That's why it's a good idea to have regular checkups even if you are feeling no pain. Other times, impacted teeth can lead to acute inflammation and infection in surrounding gum tissues that is very painful.
Should I proactively have my wisdom teeth removed if they are not giving me any trouble?
Not necessarily but your wisdom teeth need to be evaluated. Generally speaking, however, it's better to remove wisdom teeth early, before they begin to cause dental problems. By the time a wisdom tooth starts to hurt, its neighboring teeth may already be in big trouble. In addition, younger people's wisdom teeth have undeveloped roots that make them easier to remove with fewer complications.
