In the realm of restorative dentistry, dental implants are king. A dental implant can replace a tooth with a permanent, life-like restoration with a solid reputation for durability.
Implants are also known for one other quality — variety. Not all implants are alike, and they have varied applications for use. Available in various shapes and sizes, they can be used for a single tooth or as part of a multiple tooth bridge or overdenture. And while their basic architecture is the same, you also have two options for how the permanent crown (the visible tooth portion) attaches to the implant: screwed or cemented.
A screw attachment can securely fasten a crown to an implant without the need for cement; it also allows for easy removal for repair or replacement should the crown become damaged or worn. On the other hand, it could pose a cosmetic problem — even though the access hole for the screw may be covered with a tooth-colored filling, it could still be distinguishable from the rest of the crown. There’s also a slight risk of the crown chipping around the access hole.
A crown cemented to the implant won’t have this cosmetic issue with an access hole, and will look just like a natural tooth. But unlike a screwed crown, removing a cemented crown can be more difficult. The cement may also cause gum inflammation and potential bone loss in sensitive patients.
The condition of your mouth, the type of implant you’re receiving and other circumstances will all factor into determining which method is best for you. If we’re “immediately loading” the crown (meaning we’re affixing a temporary crown to the implant immediately after placement in the jaw), then the screw method may be more advantageous. Aesthetically speaking, though, a cemented crown may be a better option in terms of final smile appearance.
But whichever method is used, you’ll still benefit from what implants do best — help you regain the function lost from a missing tooth and change your smile for the better.

Did you see the move Cast Away starring Tom Hanks? If so, you probably remember the scene where Hanks, stranded on a remote island, knocks out his own abscessed tooth — with an ice skate, no less — to stop the pain. Recently, Dear Doctor TV interviewed Gary Archer, the dental technician who created that special effect and many others.
“They wanted to have an abscess above the tooth with all sorts of gunk and pus and stuff coming out of it,” Archer explained. “I met with Tom and I took impressions [of his mouth] and we came up with this wonderful little piece. It just slipped over his own natural teeth.” The actor could flick it out with his lower tooth when the time was right during the scene. It ended up looking so real that, as Archer said, “it was not for the easily squeamish!”
That’s for sure. But neither is a real abscess, which is an infection that becomes sealed off beneath the gum line. An abscess may result from a trapped piece of food, uncontrolled periodontal (gum) disease, or even an infection deep inside a tooth that has spread to adjacent periodontal tissues. In any case, the condition can cause intense pain due to the pressure that builds up in the pus-filled sac. Prompt treatment is required to relieve the pain, keep the infection from spreading to other areas of the face (or even elsewhere in the body), and prevent tooth loss.
Treatment involves draining the abscess, which usually stops the pain immediately, and then controlling the infection and removing its cause. This may require antibiotics and any of several in-office dental procedures, including gum surgery, a root canal, or a tooth extraction. But if you do have a tooth that can’t be saved, we promise we won’t remove it with an ice skate!
The best way to prevent an abscess from forming in the first place is to practice conscientious oral hygiene. By brushing your teeth twice each day for two minutes, and flossing at least once a day, you will go a long way towards keeping harmful oral bacteria from thriving in your mouth.
