The old saying, “If it ain't broke, don't fix it,” doesn't really apply when discussing your wisdom teeth. It's great if they are not bothering you, but don't wait for problems to develop before you take action. This may seem counter-intuitive, but you should know that the best time to have your wisdom teeth removed is when they are not causing problems.
Why do wisdom teeth cause problems?
Wisdom teeth are so-called because they appear at ages 17 to 25, the age of supposedly attaining wisdom. They are also known as third molars and are farthest back in your jaws. For some people they come through the gum-line only partially, or they may not erupt into the mouth at all. Unerupted they have the potential to cause problems associated with the neighboring teeth and surrounding gums.
You may have heard of “impacted” wisdom teeth. This means that they are impacted or forced against neighboring structures, teeth or bone that prevent them from coming into the mouth in correct biting position. Since they are your last teeth to come in, space for them may be severely limited. They may push into the teeth that are already in place, becoming stuck as they try to erupt. When wisdom teeth are trapped like this below the gum line and are pushing against neighboring teeth, these molars can cause problems such as infections, cysts, or gum disease.
My wisdom teeth seem OK, so why remove them?
The dilemma is that if you wait until you feel pain connected with your wisdom teeth, their neighboring teeth may already be in trouble.
Another reason to remove these back teeth before they cause problems is that it's a good idea to have your surgery while you are young. Younger, healthy patients with no infections at the site have the best chance of having their wisdom teeth extracted without complications, with an easier recovery and uneventful healing.
Of course, each situation is different. Make an appointment with us for an examination and a consultation to discuss the risks and benefits of removing your wisdom teeth. For more information read the article “Removing Wisdom Teeth” in Dear Doctor magazine.
Dental implants have come a long way since their introduction thirty years ago. Unlike their predecessors, today’s implants come in various shapes and sizes that can meet the precise needs of individual patients. Crown attachment has also developed some variety.
The actual implant is a titanium post surgically imbedded in the jawbone to replace the original tooth root. The restoration crown, the visible part of the implant system that resembles natural tooth, is affixed to the implant post. There are two basic methods to attach the crown: cement it to an abutment that has been installed in the implant; or screw it into the implant with a retaining screw from the underside of the crown. In the latter case, the abutment has been built into the crown.
While either method provides years of effective service, one method may work better than the other depending on the circumstance. Screw-retained crowns require no cement and are more easily removed than cemented crowns if it becomes necessary. On the other hand, the screw access hole can be visible, although the area can be filled with a tooth-colored filling; and although rare, chips near the access hole can occur. Occasionally the screw may become loose, but tightening or replacing the retaining screw is a simple matter because of the access hole.
A cemented crown looks more like a natural tooth and so is more useful in situations where cosmetics are a factor. The cement, however, can cause inflammation and contribute to bone loss in some patients when excess cement gets below the gums. Unlike a screw-retained crown, removal is more difficult and limited.
As a rule, screw-retained crowns are normally used in areas where the screw hole is not conspicuous, such as for posterior (back) teeth. They’re also more desirable than cemented when the implant is permanently crowned at the same time it’s surgically implanted, a process called “immediate loading.”
Which method of crown attachment is best for you? That depends on the implant location and other factors we would explore during a thorough pre-implant exam. Either way, the end result will be a life-like replica of your natural teeth, and a restored, vibrant smile.

Already read every “What to Expect” book twice over? Think you know something about how pregnancy affects your teeth and gums — and vice versa? OK, ace — test your knowledge by taking the quiz below. No peeking at the answers!
Myth or fact: The calcium in baby's teeth comes from mom's teeth.
MYTH. Calcium is needed to build baby's teeth and bones, but it should come primarily from the mother's diet, not her body. If an expectant mom's diet contains too little calcium, however, this essential mineral may be supplied from calcium stored in her bones. That's one reason why a proper diet — with an adequate intake of dairy products, plus dietary supplements, if recommended — is important throughout pregnancy.
Myth or fact: Developing symptoms of periodontal disease is common during pregnancy.
FACT. The levels of many hormones, including progesterone, are higher during pregnancy. When periodontal disease is present, progesterone stimulates the body to produce prostaglandins, which cause inflammation of blood vessels in the gum tissue. This can result in a disease called pregnancy gingivitis. Excess growths of gum tissue called “pregnancy tumors” may also develop. These benign growths are probably related to dental plaque.
Myth or fact: Untreated dental infections pose a risk to the fetus as well as the mother.
FACT. Studies have shown that pregnant women with severe periodontal disease are at greater risk for preterm birth and low birth weight babies, and may be susceptible to an increased rate of pre-eclampsia, a serious complication. This seems to be due to the fact that oral bacteria can trigger inflammatory responses in other parts of the body — even the placenta. That's why a dental evaluation is so important at the first sign of a potential problem.
Myth or fact: All moms should take fluoride supplements to help their babies form strong teeth.
MYTH (for now). The benefits of parental fluoride supplements are poorly studied, and at present remain controversial. Although baby's teeth begin forming in the second month, fluoride works best after the teeth have erupted in the mouth. So, at present, this practice isn't recommended by the American Academy of Pediatric Dentistry.
Myth or fact: Once your baby is born, it's OK to feed them pre-chewed food or slobber over them.
Myth (we gave that one away). First of all, it's gross. Second, while your baby isn't born with the bacteria that cause tooth decay, this behavior can transmit them from you to her, causing dental problems down the road. So don't do it. But do come in for a dental evaluation as soon as you know you're expecting. And have a safe and healthy pregnancy!
