It might not rise to the level of a miracle, but cosmetic dentistry can achieve some amazing outcomes with unattractive teeth. A skilled and experienced dentist can turn "ugly ducklings" into beautiful "swans." And that achievement might not be as in-depth or expensive as you might think, thanks to the increased use of dental materials called composite resins.
Composite resins are pliable, tooth-colored materials we apply directly to tooth surfaces. They're most often used with broken, chipped or misshapen front teeth—the composite material replaces the missing tooth structure.
Composite resins have been around for decades, but haven't been widely used because they didn't have the strength of dental porcelain. In recent years, though, dentists have perfected techniques for bonding and shaping composites to teeth that have increased their durability. With just the right skill and artistry, composites can look like natural teeth.
We can correct many tooth flaws using composite resins right in our office. After roughening up the outer enamel surface of the tooth and performing other steps to aid bonding, we begin applying liquid resins to form a base layer that we then harden with a special light source. We continue to add layers to increase the color depth and shape of the restoration, before finally polishing it to resemble natural teeth.
Composite restorations are ideal for moderate tooth structure loss, but may not be appropriate for heavily worn, previously root canal-treated or fractured teeth. These and other kinds of flaws may require a different solution such as a dental porcelain restoration with veneers or crowns. Where composites can be used, though, they provide an affordable option that doesn't require an outside dental lab for fabrication—we can often perform it in one visit.
If you'd like to consider a composite resin restoration for a less than perfect tooth, see us for a complete examination and consultation. If your situation appears to be compatible for using this particular technique, composite resins could change your smile for the better in just a few minutes.

The braces are finally off! But to keep your new, straighter smile you'll need to wear a retainer for some time. That's because the same structural mechanism used to move your teeth could undo what we've just accomplished.
That mechanism resides in an elastic tissue called the periodontal ligament that lies between the teeth and the bone and attaches to both with tiny fibers. While the ligament holds the teeth securely in place, it also allows for slight movement in response to bite changes. Braces "pull" the teeth in the desired new direction, and the ligament responds.
But with that pressure gone after the braces' removal, a kind of "muscle memory" can set in that moves the teeth back towards their original positions. A retainer, a dental appliance worn on the teeth, exerts just enough pressure to "retain" or keep the teeth from regressing.
Retainers are effective, but the most common type has a feature that poses potential problems: it can be removed by the wearer. Because of this, less disciplined patients might be tempted not to wear their retainer as directed. There's also a higher risk of losing one and incurring additional cost to replace it.
But there is another type, the bonded retainer, which stays permanently in the mouth until removed by an orthodontist. It's composed of a thin piece of metal that's firmly attached to the back of the teeth with dental composite material. Not only does a bonded retainer solve the problems mentioned before, it also can't be seen from the outside like a removable retainer.
A bonded retainer does have one disadvantage: because it can't be removed, it can obstruct the teeth during brushing and flossing and require more effort. You won't have as much difficulty with a removable retainer keeping teeth and gums clean. You can overcome this disadvantage, though, with specialized tools like a water flosser or a floss threader to make hygiene easier.
To choose which type of retainer is best for you or your family member, have a talk with your orthodontist. And if you choose a bonded retainer and later have it removed, be sure to switch immediately to a removable one if your orthodontist advises. With either retainer, you'll be able to preserve that hard-earned smile for years to come.
