Porcelain crowns have been used to restore problem teeth since at least the early 20th Century. Crown technology has gradually progressed from the early use of precious metals like gold or silver to more life-like porcelain crowns, often with a metal interior for added strength. Today, most crowns are all-porcelain, made with newer materials that not only look attractive but can endure under the pressures of daily chewing or biting.
While crowns are often part of restorations for missing teeth, they’re also commonly used to cap or fit over a viable tooth with structural or appearance problems. Here are 4 situations where a crown could improve a tooth’s form and function.
Traumatized teeth. A significant blow to the face or mouth could generate enough force to chip away or fracture a significant amount of structure from a tooth. If the root remains healthy and firmly attached within the jaw, however, a crown can replace the missing structure and restore the tooth’s function and appearance.
Root canal treatments. Root canal treatments remove infected or dead tissue within a tooth’s pulp chamber, its inner core, and the root canals. The procedure rescues the tooth but can in the process significantly alter the tooth’s structure and appearance. A crown not only restores the tooth but also provides added protection against further decay or tooth fracture.
Teeth with multiple fillings. We can effectively treat cavities caused by tooth decay by filling them. But with each filling we must remove more of the decayed structure and shape the cavity to accommodate the filling. After a number of times, a tooth may not have enough structure left to support another filling. If the tooth is still viable, a crown could solve this dilemma.
Abnormally developed teeth. Teeth sometimes don’t erupt in the jaw as they should and may be only partly visible. The tooth not only looks out of place but it can’t fully function like a normal tooth. Capping an abnormally developed tooth with a crown will help normalize it and allow it to blend in with surrounding teeth.

Wearing orthodontic braces brings challenges to daily life. During treatment a patient will need to avoid certain foods and habits, take more time to brush and floss properly, and may endure occasional discomfort. But the effect of metal braces on appearance can be especially difficult, especially for peer-conscious teens.
Clear aligners, though, offer an alternative to braces that could make some of these challenges easier, particularly with your appearance. Aligners are clear plastic trays that fit over the teeth to move them. They can be removed by the wearer for easier brushing and flossing or for special occasions. Best of all, they're much less noticeable than metal braces.
Clear aligners were developed thanks to advances in digital technology. An orthodontist uses a computer application incorporating the data from photographs, x-rays or CT scans of a patient's teeth and jaws to produce a series of clear plastic trays. The patient then wears each tray for about two weeks before changing to the next tray in the sequence.
The trays apply pressure much like metal braces to gradually move teeth to the desired position on the jaw. Each tray is slightly smaller in size than the previous tray in the sequence, so that the progression of tooth movement continues with each succeeding tray. The treatment time is about the same as with conventional braces.
This new orthodontic tool works well for many common bite problems, but until recently they've been limited in scope. But new designs in trays and attachments called buttons added to teeth to provide more leverage have greatly increased their use for more complex bite issues.
Clear aligners also have one other disadvantage, ironically due to one of their principal benefits, removability. Although they can be taken out, they must be worn consistently to achieve results. Some younger patients may not have the maturity level and discipline to responsibly wear their aligners as they should.
That's one issue you'll need to discuss with your orthodontist if you're considering clear aligners for your teen. But if they can maintain wearing consistency, and they have a bite problem that can be corrected with aligners, both you and your teen may find this choice more agreeable and attractive than braces.

For a healthy pregnancy, it helps to have healthy teeth and gums. In fact, the American College of Obstetricians and Gynecologists (ACOG) encourages its members to advise expectant moms to see their dentist. But maintaining oral health can be more challenging when you’re expecting. For one thing, hormonal changes make you more susceptible to periodontal (gum) disease, which has been linked to “systemic” (general body) health problems including preterm labor and low birth weight.
Periodontal (gum) disease results from the buildup of bacterial plaque on tooth surfaces in the absence of good oral hygiene. It typically starts as gingivitis — inflammation and redness around the gum margins and bleeding when brushing and flossing. If the infection progresses, it can attack the structures supporting the teeth (gums, ligaments, and bone) and may eventually result in tooth loss. And if the infection enters the bloodstream, it can pose health risks elsewhere in the body. Studies suggest that oral bacteria and their byproducts are able to cross the placenta and trigger an inflammatory response in the mother, which may in turn induce early labor.
TLC for Your Oral Environment
Brushing twice daily with fluoride toothpaste and flossing or using another interdental cleaner at least once daily is your first-line defense again bacteria buildup. Professional cleanings are also important to remove hardened plaque (calculus) that brushing and flossing may miss. And regular checkups can catch problems early to avoid or minimize adverse effects. Periodontal disease and tooth decay aren’t always painful or the pain may subside, so you won’t always know there’s a problem.
Dental emergencies such as cavities, root canals and tooth fractures should be treated promptly to address pain and infection, thereby reducing stress to the developing fetus. Of course, if you know you need a cavity filled or a root canal prior to becoming pregnant, that’s the optimal time to get treated!
