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.

Your gums aren’t just for show—they also play an important role in supporting and protecting your teeth. Healthy gums are essential for healthy teeth.
Your gums can take a lot from daily chewing or other environmental factors. Unfortunately, disease or trauma can weaken their resilience. This weakening could lead to gum recession.
Gum recession occurs when the tissues covering a tooth begin to lose their attachment and shrink back (recede). As a result, the tooth appears “longer” as more of it that’s normally below the gum line becomes visible. Not only is gum recession unattractive, it also exposes more of the tooth to disease-causing bacteria.
The most common cause for gum recession is periodontal (gum) disease, an infection arising from the accumulation of a thin bacterial biofilm on the teeth called plaque. Infected gums become inflamed, a normal defensive response to isolate diseased or damaged tissues from the rest of the body. Chronic inflammation, however, weakens affected tissues over time and results in bone loss.
Other factors can also contribute to gum recession. A tooth that didn’t erupt properly and has come in away from the center of its protective bony housing can impede adequate gum coverage. Your gum tissue thickness, which you genetically inherit, can also increase the risk of gum recession. People with thinner gum tissues are more susceptible to recession than with thicker tissues.
You can also damage your gums (ironically) while trying to care for them. Over-aggressive brushing over time may traumatize the gums to the point that they recede. While it’s essential in removing disease-causing dental plaque, brushing only requires a gentle scrubbing action covering all portions of tooth surfaces. The brush bristles and mild abrasives in the toothpaste do most of the work of plaque removal.
To minimize the chances of gum recession, you should practice proper oral hygiene and visit your dentist regularly for professional cleanings and checkups. And you might also consider orthodontics for improperly positioned teeth that could not only improve your smile, but also your gum health.
And by all means see your dentist if you notice any signs of gum infection like swollen, reddened or bleeding gums. The sooner you begin gum disease treatment, the less likely your gums will recede in the future.

Tooth loss is a problem that affects many seniors—and since May is Older Americans Month, this is a good time to talk about it. Did you know that more than a quarter of adults over age 75 have lost all of their natural teeth? This not only affects their quality of life, but poses a significant health risk.
According to a study in The Journal of Prosthodontics, significant tooth loss is associated with increased risk for malnutrition—and also for obesity. If this seems like a contradiction, consider that when you have few or no teeth, it’s much easier to eat soft, starchy foods of little nutritional value than it is to eat nutritious fresh fruits and vegetables.
That’s just one reason why it’s important to replace missing teeth as soon as possible. There are several ways to replace a full set of missing teeth including removable dentures, overdentures, and fixed dentures.
Removable dentures are the classic “false teeth” that you put in during the day and take out at night. Dentures have come a long way in terms of how convincing they look as replacement teeth, but they still have some disadvantages: For one thing, they take some getting used to—particularly while eating. Also, wearing removable dentures can slowly wear away the bone that they rest on. As that bone gradually shrinks over time, the dentures cease to fit well and require periodic adjustment (re-lining).
Overdentures are removable dentures that hook onto a few strategically placed dental implants, which are small titanium posts placed in the bone beneath your gums. Strong and secure, implants prevent the denture from slipping when you wear it. Implants also slow the rate of bone loss mentioned above, which should allow the denture to fit better over a longer period of time. But overdentures, too, are not meant to be worn all of the time.
Fixed dentures are designed to stay in your mouth all the time, and are the closest thing to having your natural teeth back. An entire row of fixed (non-removable) replacement teeth can usually be held in place by 4-6 dental implants. Dental implant surgery is an in-office procedure performed with the type of anesthesia that’s right for you. After implants have been placed and have integrated with your jaw bone—generally a period of a few months—you can enjoy all of your favorite foods again without worry or embarrassment.
