If you've lost a tooth, you have a number of options for replacing it. Perhaps the best choice in terms of lifelikeness and durability is a dental implant.
All implants have the same basic architecture: a titanium metal post imbedded in the jawbone to replace the root; and an abutment, a metal collar that links the post with a lifelike porcelain crown. But implants can vary in how the crown attaches to the abutment and post — either cemented to the abutment or screwed through the abutment to the post.
Either method will permanently secure the crown to the implant. But there are advantages and disadvantages for each.
A screw-retained crown may better facilitate any future repair that might be needed. For a skilled dentist it's a simple matter of removing the screw and then the crown from the abutment. There's less risk of damage to the implant during repairs or crown replacement. Many dentists also prefer screws for crowns placed at the same time they're installing the implant post (a procedure called immediate loading).
The screw access hole, however, could pose a cosmetic problem. Although we can cover it over with tooth-colored filling, it may still be noticeable and unattractive especially for a tooth visible when you smile (in the smile zone). There's also the possibility the porcelain around the access hole could chip.
By contrast, cemented crowns have a smooth, unbroken surface and are aesthetically ideal for smile zone teeth. But the cement could interact poorly with gum and bone tissue in some patients, causing inflammation and possible bone loss.
And unlike screw-retained crowns, cemented crowns are difficult to remove for implant repair. We may have to drill through the crown to access the screw between the abutment and the post, and then repair it cosmetically if we use the same crown. Again, the final result may not be quite as visually appealing.
In the end, it will depend on the implant's location, how your body reacts to the cement or your dentist's preference. In either case, though, you'll have a tooth replacement that's functional, life-like and able to endure for many years to come.

Magician Michel Grandinetti can levitate a 500-pound motorcycle, melt into a 7-foot-tall wall of solid steel, and make borrowed rings vanish and reappear baked inside bread. Yet the master illusionist admits to being in awe of the magic that dentists perform when it comes to transforming smiles. In fact, he told an interviewer that it’s “way more important magic than walking through a steel wall because you’re affecting people’s health… people’s confidence, and you’re really allowing people to… feel good about themselves.”
Michael speaks from experience. As a teenager, his own smile was enhanced through orthodontic treatment. Considering the career path he chose for himself — performing for multitudes both live and on TV — he calls wearing an orthodontic device (braces) to align his crooked teeth “life-changing.” He relies on his welcoming, slightly mischievous smile to welcome audiences and make the initial human connection.
A beautiful smile is definitely an asset regardless of whether you’re performing for thousands, passing another individual on a sidewalk or even, research suggests, interviewing for a job. Like Michael, however, some of us need a little help creating ours. If something about your teeth or gums is making you self-conscious and preventing you from smiling as broadly as you could be, we have plenty of solutions up our sleeve. Some of the most popular include:
- Tooth Whitening. Professional whitening in the dental office achieves faster results than doing it yourself at home, but either approach can noticeably brighten your smile.
- Bonding. A tooth-colored composite resin can be bonded to a tooth to replace missing tooth structure, such a chip.
- Veneers. This is a hard, thin shell of tooth-colored material bonded to the front surface of a tooth to change its color, shape, size and/or length; mask dental imperfections like stains, cracks, or chips, and compensating for excessive gum tissue.
- Crowns. Sometimes too much of a tooth is lost due to decay or trauma to support a veneer. Instead, capping it with a natural-looking porcelain crown can achieve the same types of improvements. A crown covers the entire tooth replacing more of its natural structure than a veneer does.
