X-rays are so interwoven into dental care that we often don't think twice about them. Even so, we shouldn't take this invisible form of radiation lightly—regular exposure at high levels can affect the human body, especially in children.
The ability of x-rays to pass through tissue greatly improves our ability to diagnose tooth decay and other dental diseases. But x-rays can also potentially harm those same tissues. Because children are more sensitive to x-ray energy, they run a greater risk for cellular damage that could lead to cancer later in life.
In reality, though, these potential risks from x-rays are extremely low—so low, in fact, dental professionals regard their use as altogether safe for children. Here's why.
The ALARA principle. Dentists and other healthcare providers perform x-ray diagnostics based on a principle known as ALARA (“As low as reasonably achievable”). This means dentists only utilize x-rays to gain the most diagnostic benefit at the lowest amounts of radiation exposure. As such, ALARA guides both the development of x-ray equipment and the protocols involved in using them.
Equipment advances. Today's x-ray devices are safer and more efficient, restricting x-ray emissions to a single beam without scattering radiation into the environment. A child's radiation exposure is further lowered with the use of digital x-rays, which produce images in less time than conventional film. Because of these and other advances, children are exposed to less radiation during x-rays than what they typically receive in a day from the outside environment.
Safe practices. Following the ALARA principle, dentists are quite conservative in their use of x-rays in children. The most common means of x-ray is the bitewing, which captures images primarily of the back teeth that are more prone to decay. Bitewings, which require a lower x-ray dosage than a full mouth x-ray, are usually spaced at least six months apart or longer depending on a child's risk for dental disease.
The efficiency of modern radiographic equipment coupled with their judicious use has drastically reduced the amount of x-ray radiation to which a child may be exposed, thus lowering their risk of future health issues. The benefit for saving a child's teeth from disease is well worth their use.

Dentists remove millions of teeth each year, often because of tooth decay or gum disease. But disease isn't the only reason—a tooth extraction might make it easier to straighten a crooked smile.
Realigning teeth for therapeutic or cosmetic reasons is a regular undertaking in dentistry, but the process itself often differs from person to person. Each individual patient requires their own treatment plan taking into account factors like the kind of bite problem involved, the size of the jaw and the space available to move teeth.
This plan could indeed involve removing teeth. For example, an abnormally small jaw could cause crowding. Not only can crowding move teeth out of position, it may also leave little to no room for moving teeth. Although dentists can minimize crowding by influencing jaw development in early childhood, removing teeth for more space is usually the only option available to older adolescents and adults.
Similarly, teeth can fail to erupt properly and remain partially or fully submerged beneath the gums (known as impaction). There is an orthodontic method for pulling an impacted tooth fully onto the jaw, but only if the tooth isn't too far out of alignment. Otherwise, it may be better to remove the impacted tooth and then correct any gaps with braces or a dental implant.
There's also a situation on the opposite side of the spectrum that could benefit from teeth removal—when one or more permanent teeth fail to form, known as congenitally missing teeth. This can cause gaps in the smile or a “lopsided” appearance where a tooth on one side of the jaw is present while its counterpart on the opposite side of the jaw is missing.
The missing tooth can be replaced by an implant, bridge or other restoration. But another option may be to remove the existing counterpart tooth, and then close the gaps. This can result in a much more attractive smile that might be simpler and less costly than replacing the missing tooth.
Again, the decision to remove teeth to improve smile appearance depends on the patient and their particular dental condition. But in the right situation, it could make straightening a smile easier and more effective.

Kill Bill fans have been pressing for a third installment of the stylized revenge tale since Kill Bill, Volume 2 hit the theaters in 2004. Finally, filmmaker Quentin Tarantino is talking about the long-awaited Volume 3 as if it might soon become a reality. The third movie in the franchise would most likely focus on the now-grown daughter of the character played by Vivica A. Fox in the first two. Vivica recently made known that should Kill Bill, Volume 3 go into production, she thinks 24-year-old actress and singer Zendaya would be perfect for the role.
Although Zendaya is a few inches taller than Vivica, the two women have a few things in common. Besides being talented movie and television actresses who have won awards for their roles, they both have camera-ready smiles. And both Vivica and Zendaya can thank their dentists for helping their smiles be their best.
In 2016, Vivica told Dear Doctor magazine that her smile needed a boost, so she opted for dental veneers to correct gaps between her teeth—and she's very happy with them. “I love my veneers!” she exclaimed. Zendaya also had help in achieving her Hollywood-perfect smile. In 2011, early in her career on the Disney channel, she wore clear orthodontic aligners to straighten her teeth. To further perfect her smile, she visited her dentist for professional teeth whitening in 2016, inviting a film crew along to show how easy and effective in-office tooth whitening is.
But you don't have to be a celebrity to enjoy smile-enhancing dental treatments. They are great options for anyone who wants to improve the look of their smile.
Teeth whitening. If your teeth are looking yellowed, in-office whitening can make them up to 10 shades brighter in one visit! Some people prefer professional at-home whitening kits, which produce great results more gradually.
Bonding or veneers. For small chips and cracks, cosmetic bonding can cover flaws by adding layers of a tooth-colored material over the tooth. For bigger flaws, heavy discoloration or gaps between teeth as Vivica had, dental veneers may be the answer. These custom-made thin porcelain shells cover the front-facing surface of the tooth, hiding imperfections to give anyone a Hollywood smile.
Orthodontics. Crooked teeth can detract from the look of a smile. While traditional braces are an option, many people with mild to moderate alignment issues find removable clear aligners the perfect way to get the smile they desire with minimal impact on their daily activities. Clear aligners are very subtle and can be removed for eating and cleaning as well as for special occasions—or for filming scenes, as Zendaya knows.
