If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

Although teeth are quite durable, we can still lose them—even all of them—to disease or injury. The good news, though, is that we have effective ways to restore teeth after they're lost. One of these, the removable denture, has given people their teeth back for several generations. And with recent advances in technology, today's dentures are even better.
Although more advanced, today's dentures share the same basic structure as those from a century ago: prosthetic (false) teeth set in a plastic resin colored to resemble the gums. The traditional denture is molded to fit snugly over an individual patient's alveolar jaw ridges, which once supported the former natural teeth. The denture stays in place primarily through a suction effect between the denture and the ridges.
Modern technology, though, has greatly improved today's dentures. Digital imaging can be used to generate highly accurate impressions of the dental ridges that can lead to denture bases with better fit. Dentists using photographs of the patient, especially in earlier years, are better able to identify facial landmarks, which enables them to position the new teeth to more closely recreate the patient's former smile.
These technological aids now help dentists to create more attractive dentures with better support and comfort. But the fit that makes this possible may not last due to a particular weakness inherent in traditional dentures—continuing bone loss. When teeth are missing, the underlying jawbone can lose bone volume over time. Dentures don't stop this process and can accelerate it due to constant friction and pressure on the dental ridges.
But a new modification incorporating dental implants with dentures can help solve these problems. By placing a few strategically positioned implants in the jawbone that then connect with the denture, the appliance not only gains more stability, but also produces less pressure on the dental ridges. In addition, bone cells naturally grow and adhere to the titanium implant posts, which helps to stop or slow bone loss.
If you've experienced total tooth loss, dentures are an affordable and effective option. Thanks to modern dental advances, you can get back the smile and dental function you once lost.

We Americans love our sports, whether as participants or spectators. But there's also a downside to contact sports like soccer, football or basketball: a higher risk of injury, particularly to the mouth and face. One of the most severe of these is a knocked out tooth.
Fortunately, that doesn't necessarily mean it's lost: The tooth can be reinserted into the empty socket and eventually return to normal functionality. But it must be done as soon as possible after injury. The more time elapses, the lower the chances of long-term survival.
That's because of how teeth are held in place in the jaw, secured by an elastic, fibrous tissue known as the periodontal ligament. When a tooth is knocked out some of the ligament's periodontal cells remain on the tooth's root. If these cells are alive when the tooth is reinserted, they can regenerate and reestablish attachment between the ligament and the tooth.
Eventually, though, the cells can dry out and die. If that has already happened before reinsertion, the tooth's root will fuse instead with the underlying bone. The tooth may survive for a short time, but its roots can eventually dissolve and the tooth will be lost.
Your window of opportunity for taking advantage of these live periodontal cells is only 5-20 minutes with the best chances in those earlier minutes. You should, therefore, take these steps immediately after an injury:
- Find the tooth, hold it by the crown (not the root end), and rinse off any debris with clean water;
- Reinsert the root end into the empty socket with firm pressure;
- Place clean gauze or cloth in the person's mouth between the tooth and the other jaw, and ask them to bite down gently and hold their bite;
- Seek dental or emergency medical care immediately;
- If you're unable to reinsert the tooth, place it quickly in a container with milk and see a dentist immediately.
You can also obtain an Android or IOS smartphone app developed by the International Association of Dental Traumatology called ToothSOS, which will guide you through this process, as well as for other dental emergencies. The quicker you act, the better the chances that the injured person's knocked out tooth can be rescued.

Kill Bill fans have been pressing for a third installment of the stylized revenge tale since Kill Bill, Volume 2 hit the theaters in 2004. Finally, filmmaker Quentin Tarantino is talking about the long-awaited Volume 3 as if it might soon become a reality. The third movie in the franchise would most likely focus on the now-grown daughter of the character played by Vivica A. Fox in the first two. Vivica recently made known that should Kill Bill, Volume 3 go into production, she thinks 24-year-old actress and singer Zendaya would be perfect for the role.
Although Zendaya is a few inches taller than Vivica, the two women have a few things in common. Besides being talented movie and television actresses who have won awards for their roles, they both have camera-ready smiles. And both Vivica and Zendaya can thank their dentists for helping their smiles be their best.
In 2016, Vivica told Dear Doctor magazine that her smile needed a boost, so she opted for dental veneers to correct gaps between her teeth—and she's very happy with them. “I love my veneers!” she exclaimed. Zendaya also had help in achieving her Hollywood-perfect smile. In 2011, early in her career on the Disney channel, she wore clear orthodontic aligners to straighten her teeth. To further perfect her smile, she visited her dentist for professional teeth whitening in 2016, inviting a film crew along to show how easy and effective in-office tooth whitening is.
But you don't have to be a celebrity to enjoy smile-enhancing dental treatments. They are great options for anyone who wants to improve the look of their smile.
Teeth whitening. If your teeth are looking yellowed, in-office whitening can make them up to 10 shades brighter in one visit! Some people prefer professional at-home whitening kits, which produce great results more gradually.
Bonding or veneers. For small chips and cracks, cosmetic bonding can cover flaws by adding layers of a tooth-colored material over the tooth. For bigger flaws, heavy discoloration or gaps between teeth as Vivica had, dental veneers may be the answer. These custom-made thin porcelain shells cover the front-facing surface of the tooth, hiding imperfections to give anyone a Hollywood smile.
Orthodontics. Crooked teeth can detract from the look of a smile. While traditional braces are an option, many people with mild to moderate alignment issues find removable clear aligners the perfect way to get the smile they desire with minimal impact on their daily activities. Clear aligners are very subtle and can be removed for eating and cleaning as well as for special occasions—or for filming scenes, as Zendaya knows.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
