Most of us wouldn't think of buying a new car without a “test drive.” It's a serious investment, so you want to make sure you're comfortable with your new ride.
Like an auto purchase, the plan you and your dentist agree on to cosmetically enhance your teeth and gums — a “smile makeover” — is a significant investment. Wouldn't it be nice to “test drive” your future smile before you undergo any procedures?
Actually, you can — two ways, in fact. For one, your dentist could use computer imaging software that alters a photo of your face to show how your smile will appear after dental work. These computer enhancements are a great planning tool for making decisions on the look you want to achieve.
But even the best computer images only provide a static, two-dimensional representation of your new smile. It can't capture all the angles and movement dynamics of any proposed changes. That's where the other way, a trial smile, is a true test drive — you can see your future smile in action.
With a trial smile, your dentist temporarily places tooth-colored material called composite resin on your teeth to simulate the proposed changes. The resin can be shaped and sculpted to create a life-like replica that you'll be able to view in all three spatial dimensions. What's more it will give you a chance not only to see what your new smile will look like, but to actually experience how it feels in your mouth.
Creating a trial smile is an added expense and it's only available during your consultation visit — the dentist will need to remove the resin before you leave. But you'll still be able to get a good impression of what your final smile will be like. You'll also be able to take photos you can show to family and friends to get their impressions of your proposed new look.
A trial smile allows you to know beforehand what your dental work investment will provide you, and even fine-tune your makeover plan before work begins. With this particular kind of “test drive” you'll have greater assurance that you'll be happy and satisfied with the end results.

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.
