Untreated tooth decay can destroy your teeth; prompt action as soon as its diagnosed will help prevent that undesirable outcome. And even if decay has advanced into the tooth's pulp and root canals, there's still a good chance we can stop it with a root canal treatment. Using this procedure, we can clean out the infection and refill the tooth's interior space with a special filling to protect it from further infection.
Although root canal treatments have gained an unwarranted reputation for pain, they rarely cause even the mildest discomfort. More importantly, they work, which is why they're the go-to treatment dentists use for advanced decay.
But sometimes a unique dental situation might make performing a root canal extremely difficult—possibly even doing more harm than good. For example, trying to access the interior of a tooth with a crown restoration might require removing the crown, which could further weaken or damage the tooth. In other cases, the root canals might have become calcified due to trauma or aging and become too narrow to access.
Even so, we may still be able to save a tooth through a minor surgical procedure called an apicoectomy. Rather than access the diseased area through the tooth crown as with a root canal treatment, an apicoectomy makes access to the infected tissue at the root end.
An apicoectomy also differs from a root canal treatment in that we'll need to surgically go through the gum tissue. After numbing the area with a local anesthetic, we'll make a small incision through the gums at the level of the infection. After removing any infected tissue, we would then fill the space with a small filling to prevent re-infection. We then close the incised gum tissues with sutures and allow them to heal.
With the help of fiber optic lighting and surgical microscopes, endodontists (specialists in interior tooth problems) can perform an apicoectomy quickly and with very little trauma at the surgical sight. If you undergo an apicoectomy, you should be back to normal activity in a day or two at the most. And like its sister procedure the root canal, an apicoectomy could help preserve your teeth for many years to come.

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.

A beautiful smile is a balanced smile, especially in regard to your gums. A normal smile usually shows 4 mm or less of gum tissue along with about 10 mm of tooth length. But if your gums show more than that, your smile may seem too gummy. In terms of perceived balance, this could detract from your smile's attractiveness.
Fortunately, you don't have to live with a gummy smile—there are various ways to correct or minimize its effect. First, though, we'll need to determine the underlying cause before deciding on the best treatment. And, there are several possible causes, the obvious being too much gum tissue present. Teeth that appear shorter due to wear or incomplete eruption could also make the gums appear larger.
We may be able to correct these size problems by surgically removing and reshaping excess gum tissues and possibly the underlying bone to reveal more of the teeth. We can also bond composite resins or porcelain veneers to shorter teeth to make them appear larger.
But not all gummy smile problems pertain directly to the teeth and gums; instead, it could be your upper lip moves too far up as you smile (hypermobility). Or, your upper jaw may be too long for your face, which can also cause too much of the gums to show during smiling.
With upper lip hypermobility, we may be able to inhibit the lip muscles' movement temporarily with Botox injections that partially paralyze the muscles (the effect eventually wears off, so this treatment will need to be repeated). A periodontist, an oral surgeon, or a plastic surgeon could also permanently alter the upper lip movement through a surgical procedure. Surgery may also be necessary for an abnormally long upper jaw: orthognathic surgery re-positions the jaw to the skull, which can lessen the amount of gums showing.
If your smile is too gummy, we can transform it. But first, let's find out what the real cause is with a comprehensive dental examination. Once we know, we can better advise you on the best way to bring beautiful balance to your smile.
