Sometimes you need only a single solution to improve your smile: teeth whitening to brighten stained teeth; porcelain veneers or crowns to mask dental flaws; or a life-like dental implant to replace a missing tooth. But not all dental situations are that simple and sometimes require a combination of treatments.
A case in point: restoring a missing tooth within a poor bite. The absent tooth itself may be the cause of the bite problem if it’s been missing for some time: The nearby teeth tend to move or “drift” into the empty space, leaving no room for implant placement.
When this happens, you’ll first need orthodontic treatment to correct the bite problem. Not only will this open the space for the implant, it also comes with its own benefits. It obviously improves your smile appearance—but straighter teeth are also easier to keep clean of bacterial plaque, which reduces your disease risk. You may also experience better digestion after your teeth are properly aligned and able to function as they should during eating.
The traditional way to improve a bite is through metal braces. But there are some downsides: For one, braces can make it difficult to keep teeth adequately clean, making wearers more susceptible to tooth decay and gum disease. Braces are also quite visible and can detract from a person’s appearance (even more so if a missing tooth is involved).
Unless your situation requires braces, you can choose clear aligners as an alternative. These clear, computer-generated plastic trays are worn in sequence to gradually move teeth to their desired positions. Unlike braces, you can remove aligners for eating, cleaning or rare special occasions. And, they’re barely noticeable to others.
If you also have a missing tooth, you can have a temporary prosthetic (“false”) tooth built into your aligner trays. In this way you can still enhance your smile while undergoing aligner treatment.
Once your bite has been corrected, we can then proceed with restoring your missing tooth permanently with a dental implant. Although orthodontics adds to the time and expense of restoration, its often necessary to achieve the best result. Your future smile will be the better for it.
If you’ve ever read online that root canal therapy causes cancer, don’t be alarmed—it doesn’t. What it does do is save a deeply decayed tooth that might otherwise be lost.
Tooth decay is caused by acid produced by bacteria, which dissolves enamel to create a hole or cavity. But it doesn’t stop there: decay can move on to infect the tooth’s innermost layer, the pulp filled with nerves and blood vessels. Unchecked, the resulting infection can travel through the root canals to eventually infect the bone.
A root canal treatment stops the infection before it goes this far. After administering a local anesthetic, we drill a small hole into the tooth to access the pulp chamber and root canals. We then remove all the diseased tissue, disinfect the space and then place a filling within the empty chamber and root canals to prevent further infection. We then seal the access hole and later crown the tooth to further protect and stabilize it.
It’s no exaggeration, then, to say that root canal treatments have saved millions of teeth. So, for all its beneficial effect, why is it considered by some to pose a health danger?
The germ for this notion comes from the early 20th Century when a dentist named Weston Price theorized that leaving a “dead” organ in place would harm the body. Since a root-canaled tooth with the pulp’s living tissue removed is technically no longer viable, it fit the category of “dead” tissue. Thus, according to this theory, maladies like cancer could arise because of the “dead” tooth.
Unfortunately, this theory has found a somewhat new life recently on the internet, even though it was thoroughly investigated and debunked in the 1950s. And as late as 2013, a study published in a journal of the American Medical Association found no increased cancer risk after root canal treatment, and even some evidence for a reduced risk.
So, if your dentist recommends root canal treatment, rest assured it’s needed to save your tooth. Rather than harm your health, it will improve it.

You can find some version of the ever popular kids’ meal at most major fast-food restaurants. It’s a neat little package: child’s size portions of burgers, chicken nuggets or sides—and often a small toy or treat to boot—all tucked into its own colorful cardboard container.
The drive-thru menu board at your favorite fast-food joint gives you plenty of choices to fill out your child’s meal. But you may notice something missing on many major chains’ kids’ menus—the mention of soft drinks as a beverage choice. You can still get one for your child’s meal, but the visual cue is no more on the menu board.
None of the “Big Three”—Burger King, McDonald’s or Wendy’s—post soft drinks as a menu item for their kid’s meals. It’s the result of an effort by health advocates promoting less soda consumption by children, the leading source of calories in the average child’s diet. With its high sugar content, it’s believed to be a major factor in the steep rise in child obesity over the last few years.
Sodas and similar beverages are also prime suspects in the prevalence of tooth decay among children. Besides sugar, these beverages are also high in acid, which can erode tooth enamel. These two ingredients combined in soda can drastically increase your child’s risk of tooth decay if they have a regular soda habit.
You can minimize this threat to their dental health by reducing their soda consumption. It’s important not to create a habit of automatically including sodas with every meal, especially when dining out. Instead, choose other beverages: Water by far is the best choice, followed by regular milk. Chocolate milk and juice are high in sugar, but they’re still a healthier choice than sodas due to their nutrient content.
Keeping sodas to a minimum could help benefit your child later in life by reducing their risk for heart disease, diabetes and other major health problems. It will also help them avoid tooth decay and the problems that that could cause for their current and future dental health.
For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.
