First introduced in the 1980s, dental implants are a popular and reliable tooth replacement option. Numerous studies show that after ten years 95% are still in place. Much of this success owes to the implant’s titanium post imbedded directly into the jaw, which then attracts bone growth. This additional growth securely anchors the implant in place for an unrivaled durability among other replacement options.
Still, a small percentage of implants fail — some in the first few months and others after a few years. Here are 3 reasons why, and how you can overcome them.
Poor bone quantity and quality. Implants need a certain amount of existing bone to succeed. Sometimes, though, there isn’t enough because prolonged absence of a tooth causes bone loss around the empty socket. Conditions like diabetes, osteoporosis or tobacco use can also compromise bone health. It’s often possible to increase bone volume with grafting, especially right after tooth extraction.
Teeth grinding habits. This occurs when you unconsciously grind or clench your teeth, usually during sleep. The habit can create forces far in excess of what’s normal when we bite or chew and can damage or even break the crown attached to an implant. Besides reducing stress (a major factor for teeth grinding), you can also alleviate the abnormal force generated by wearing a night guard.
Periodontal (gum) disease. Although your implants are impervious to disease or infection, supporting gums and bone aren’t. Plaque, a film of food and bacteria that builds up on tooth surfaces, can cause gum disease that weakens the supporting tissues (gums and bone) of the implant. This can give rise to a specific condition with implants known as peri-implantitis where the infected gum tissues and bone around it deteriorate, leading to the implant’s catastrophic loss. To avoid this, practice consistent daily hygiene, including around the implant. And see us regularly for checkups and cleanings, or as soon as possible if you see signs of gum problems.

It’s a big moment after months of wearing braces to finally get a glimpse of your new smile. The crooked teeth and poor bite are gone — and in their place are beautiful, straight teeth!
If you’re not careful, though, your new look might not last. That’s because the natural mechanism we used to straighten your teeth may try to return them to their previous poor positions.
Contrary to what many people think, teeth aren’t rigidly set within the jaw bone. Instead, an elastic, fibrous tissue known as the periodontal ligament lies between the teeth and the bone and attaches to both with tiny fibers. Though quite secure, the attachment allows the teeth to move in very minute increments in response to growth or other changes in the mouth.
Orthodontic appliances like braces or clear aligners put pressure on the teeth in the direction we wish them to move. The bone dissolves on the side of the teeth where pressure is being applied or facing the direction of movement and then builds up on the other side where tension is occurring.
The ligament, though, has a kind of “muscle memory” for the teeth’s original position. Unless it’s prevented, this “memory” will pull the teeth back to where they used to be. All the time and effort involved with wearing braces will be lost.
That’s why it’s important for you to wear an appliance called a retainer after your braces have been removed. As the name implies, the appliance “retains” the teeth in their new position until it’s more permanently set. For most people, this means wearing it for twenty-four hours in the beginning, then later only a few hours a day or while you sleep.
The majority of younger patients eventually won’t need to wear a retainer once bone and facial growth has solidified their teeth’s new position. Older adults, though, may need to wear one from now on. Even so, it’s a relatively slight inconvenience to protect that beautiful, hard-won smile.

You’re a bit self-conscious about your smile. But not because of your teeth — it’s your upper gums, which seem too prominent when you smile. While “too much” is a matter of perception varying from individual to individual, it’s generally accepted that a smile is “gummy” if four or more millimeters (a bit more than an eighth of an inch) of the gums are visible.
The good news is there are ways to improve the appearance of your gums. Which method we use, though, will depend on the underlying reason why the gums are prominent. The amount of gum tissue, in fact, may not be the problem at all, but could be the size of the crowns (the visible parts of teeth), the upper lip’s range of motion, the upper jaw’s position in relation to the face, or a combination of any of these.
For example, if your teeth didn’t erupt and develop properly, the gums might not have moved back to their proper position and stabilized as they should in your late teens or early twenties. A normal crown (the visible part of a tooth) is about 10 millimeters long, with a ratio of width to length of about 75-85%. Below those measurements the teeth can appear smaller, making even normal gum tissue appear larger. In another scenario, the upper lip may rise too high when you smile (hypermobility), which reveals too much of the gums.
If tooth size is the problem, we may recommend a periodontal surgical procedure called crown lengthening that reveals more of the tooth. A hypermobile lip can be treated with Botox shots to temporarily restrict the movement (it must be repeated every six months) or by surgically repositioning the lip muscles that control movement. Similarly, surgically repositioning an overlong upper jaw to make it appear shorter may be the right course.
That’s why our first step is to determine why your gums are too prominent with a complete dental examination. Knowing exactly why they stand out will help us devise a treatment plan that will greatly enhance your smile.

For most dental procedures you’re usually back to your regular routine in no more than a day or two (or even hours) afterward. For the most part, the mouth heals rather quickly.
But there may still be a short period of discomfort after tooth extraction, gum surgery or similar invasive procedures. The good news is you will most likely have no need for strong narcotic painkillers — milder, over-the-counter pain relievers are usually sufficient to manage your discomfort.
The most common of these are known as non-steroidal anti-inflammatory drugs (NSAIDs). This group of pain relievers — which include aspirin and ibuprofen — block the release of substances in the body known as prostaglandins that stimulate inflammation that increases pain in damaged tissues. They’re much preferred for mild to moderate pain because they don’t have the side effects of steroids or narcotics like morphine or codeine. They also tend to be less costly than these other prescription drugs.
But while they’re reasonably safe, they can cause problems if you exceed the recommended dosage or use them for prolonged periods. Their blockage of certain chemicals reduces the clotting mechanism in blood leading to a blood-thinning effect. Not only will this increase bleeding, it can also damage the stomach lining and cause ulcers if used over a period of weeks. Improper dosage of NSAIDs has also been linked to miscarriages and repeat heart attacks, which is why they’re not recommended for use during pregnancy or with patients with a history of heart or intestinal problems.
But if taken as directed by your physician or dentist — usually no more than 2,400 milligrams a day and only for a few days — such side effects are quite rare. The benefit is much more common: about five hours of pain relief from a single dose for most people. With the help of ibuprofen or similar drugs, you’ll be on your feet after your dental work in no time.Â

There are instances when a general dentist will remove (extract) a problem tooth. At other times, though, the same dentist may refer a patient needing an extraction to an oral surgeon. Why the difference?
The procedure performed by a general dentist is referred to as a “simple tooth extraction.” “Simple” doesn’t mean easy and requiring no skill or expertise — it certainly does. In this case, the term refers to the anatomy of the tooth being extracted, particularly its roots.
Teeth that respond well in a simple extraction have an uncomplicated root system. The path of removal, usually with a single root involved, is fairly straight and without extreme angles. In the hands of a skilled and experienced dentist, it can be removed with little to no discomfort.
Dentists actually must use finesse to remove a tooth from its socket. The tooth is held in place with tiny collagen fibers that extend from a tough, elastic gum tissue known as the periodontal ligament, which lies between the teeth and the bone. With some manipulation, a dentist can loosen these fibers, which then makes removing the tooth much easier. All of this can usually be performed with local anesthesia.
Of course, to determine if a tooth can be removed this way, we must conduct a thorough dental examination first, including x-ray imaging to determine the exact nature and location of the roots. If the exam reveals the root system is more complex, or that there are defects to the bone or the tooth that could make a simple extraction difficult (resulting, for example, in not removing the crown and root in one piece), then the tooth may need to be removed surgically.
Such situations require the skill and resources of an oral surgeon. These specialists perform a number of surgical procedures related to the mouth and face; as procedures go, extraction is among the most routine. Using local anesthesia and post-operative pain management, undergoing a surgical extraction involves only minimal discomfort and a very short recovery time.
After examining your tooth we’ll recommend the best course for extraction, whether simple or surgical. In either case, we’ll see that your problem tooth is extracted as efficiently and painlessly as possible.
