We treat most malocclusions (bad bites) with braces or clear aligners. But not all malocclusions are alike — some can require extra procedures to achieve successful results.
One such example is when incoming teeth crowd other teeth and cause them to erupt abnormally. The crowding also reduces the space needed to move the misaligned teeth to better positions. To make more room we'll often remove some of the teeth before undertaking orthodontics.
The key is to extract the right teeth. The best candidates are those whose absence will have minimal effect on both appearance and dental function. That's commonly the bicuspids, located right on the edge of the “smile zone” (the teeth most visible when we smile) between the cuspid (eye) teeth and the back molars.
Once we choose and remove the teeth our next concern is to protect the bone at the extraction site.Â The bone in our jaws benefits from the pressure created when we bite or chew. This stimulates new bone cells to form and replace older cells. Without it, as when we have a missing tooth, the amount of bone can diminish over time and affect the success of any future orthodontics.
To prevent this, we take care not to damage the gums and bone removing the tooth. We may also install a graft under the empty socket to encourage bone growth.
If we've removed teeth outside the smile zone, the resulting orthodontics will move teeth into the opened space. In the end, you won't even notice they're gone. Teeth lost or congenitally missing in the smile zone, though, may eventually require a replacement tooth. A dental implant is the best choice, but it should be put on hold for a younger person until their jaw has fully developed.
In the meantime, we can install a spacer or a temporary restoration to hold the empty space and prevent other teeth from drifting into it. This can be incorporated into braces or aligners, or with a removable partial denture or a temporary modified bridge.
Extracting teeth to aid orthodontics first requires a well-laid plan that could encompass several years. The end result, though, can be well worth the time and effort — better function and a new, attractive smile.

When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!
Losing a tooth affects not only your smile but your overall dental health too. A dental implant solves both issues: it replaces the whole tooth, including the root, to merge durability with a life-like appearance.
For teenagers with a missing tooth, however, an implant may not be a good idea, at least until they've physically matured. Although their permanent teeth have usually all come in by puberty, the jaws and facial structure continue to develop into early adulthood. An implant placed too early could appear misaligned when the jaw fully matures.
The best approach for teens is a temporary replacement until they're physically ready for an implant. There are two good options: a removable partial denture (RPD) or a fixed bonded bridge.
Common among adults, an RPD is also a viable replacement for a teenager's missing tooth. An RPD consists of a prosthetic (false) tooth set in a nylon or acrylic base that resembles gum tissue. Metal clips formed in the RPD fit over adjacent teeth to hold the appliance in place; this also makes it easy to remove for cleaning or sleep time. We typically recommend an acrylic base for teens because it's easier to adjust if the RPD's fit becomes loose.
To hold it in place, a traditional bridge uses crowns on either side of the replacement tooth to bond over the natural teeth next to the open socket. Because this requires permanently altering the support teeth, we recommend a bonded bridge that doesn't.
This modified bridge uses wing-like strips of dental material on the back of the false tooth that project outward. With the tooth in place, we bond the extending portions of these projections to the back of the adjacent teeth, which secures the false tooth in place.
Of the two options, the bonded bridge is more comfortable, buys the most time and looks the most natural. But it will cost more than an RPD. Bite issues, teeth grinding, overall gum health or your child's level of hygiene conscientiousness could also nix it as a viable option.
Either choice will effectively replace your child's missing tooth until it's time for a permanent restoration. We'll help you weigh all the factors to determine which one is best for your situation.
