“To gain something, sometimes you have to give up something else.”
No, that isn't the latest viral meme on the Internet. It's actually a practical consideration that could arise in orthodontics.
In this case, the “something” to gain is a straighter, more attractive smile; the “something” you may have to part with is a few teeth. This may be necessary if there are too many teeth on a dental arch for its capacity, a situation called crowding. A lack of space is the main reason teeth come in misaligned.
Before we can correct this, we'll need to free up space to allow for tooth movement by removing one or more of the existing teeth. The ideal candidates are those that are near to the teeth we wish to move but not highly visible. The first bicuspids are the most frequent choices for removal: they're located behind the cuspids or eyeteeth (the pointed teeth right under the eyes).
Ideally, we'll remove the target teeth some time before we apply braces to give the gums a chance to heal. At the same time we want to preserve the bone that once supported the teeth we've extracted. This is because when we chew the forces generated by the teeth stimulates bone replacement growth. When a tooth is no longer there the supporting bone doesn't receive this stimulation and may ultimately reduce in volume.
We may try to prevent this by placing a bone graft in the empty socket immediately after removing the tooth. The graft serves as a scaffold to encourage new bone to grow. Hopefully when we're ready to apply braces, the bone will be strong and healthy to handle the movement of the teeth.
As the teeth move under the influence of braces, they'll begin to fill up the space created by tooth removal. Once it's completed, the extracted teeth won't be missed — the other teeth now straightened will completely fill out the smile.
The different steps in this process must be carefully planned and executed precisely, and it will take months or even years to complete. In the end, though, this complicated bite problem can be corrected and replaced with an attractive, straight smile.

At your child's latest dental visit, you found out one of their primary (“baby”) teeth has become decayed and in danger of loss. Of course, you may think, it's only a primary tooth — it's going to come out sooner or later.
But a primary tooth lost “sooner” rather than “later” can create long-term negative consequences for your child's dental health. For the sake of the future permanent tooth, the best treatment strategy could be to put forth the effort and expense to save it.
Besides its role in eating and chewing, a primary tooth's most important function is as a “trailblazer” for the permanent tooth developing below it. A primary tooth doesn't normally loosen and let go until the new permanent tooth is ready to erupt. Until then they hold the new tooth's space in the jaw.
But if the primary tooth is lost prematurely, nearby teeth can drift into and crowd the space so that the permanent tooth comes in out of position. This can result in a malocclusion, or poor bite.
Depending on the state of your child's jaw development, it may be advisable to attempt saving the tooth through a filling or, in the case of deep decay, a modified root canal treatment. If the tooth can't be saved, then placing an orthodontic appliance known as a space maintainer might be necessary. Cemented to a tooth next to the empty space, this appliance has a looped band of metal that butts against the tooth on the other side of the gap, and prevents both teeth from drifting into the space.
Intervening for a decayed primary tooth can seem a waste of time and money since it has a limited lifespan to begin with. But for the health of its companion permanent tooth, as well as possibly avoiding orthodontic treatment, it could be well worth it for your child's long-term dental health.

There are a variety of methods for treating periodontal (gum) disease depending on its severity — from routine office cleanings to periodontal surgery. But the goal behind all of them remains the same: remove bacterial plaque and calculus (tartar), the root cause for gum disease, from all tooth and gum surfaces.
The traditional method for doing this is called scaling in which we use special hand instruments (scalers) to mechanically remove plaque and calculus. Scaling and a similar procedure called root planing (the root surfaces are “planed” smooth of plaque to aid tissue reattachment) require quite a bit of skill and experience. They're also time-consuming: full treatment can take several sessions, depending on how extensive the infection has spread.
In recent years, we've also seen a new method emerge for removing plaque: lasers. Commonly used in other aspects of healthcare, lasers utilize a focused beam of light to destroy and remove diseased or unhealthy tissue while, according to studies and firsthand accounts, minimizing healthy tissue destruction to a better degree than traditional techniques. Procedure and healing times are likewise reduced.
Because of these beneficial characteristics, we are seeing their use in gum disease treatment, especially for removing diseased and inflamed tissues below the gum line and decreasing sub-gingival (“below the gums”) bacteria.
Dentists who have used lasers in this way do report less tissue damage, bleeding and post-treatment discomfort than traditional treatments. But because research is just beginning, there's not enough evidence to say laser treatment is preferably better than conventional treatment for gum disease.
At this point, lasers can be an effective addition to conventional gum disease treatment for certain people, especially those in the early stages of the disease. As we continue to study this technology, though, the day may come when lasers are the preferred way to stop gum disease from ruining your dental health.

We've known for a long time that fluoride strengthens tooth enamel against decay. We've also learned that fluoride consumption early in life pays later dividends with healthier teeth.
But while fluoride has generally proven safe, too much ingested by young children could cause enamel fluorosis. This condition produces a mottled or streaked appearance in teeth ranging from faint white patches to darker, pitted staining. Fluorosis doesn't harm teeth, but it does make them less attractive.
To prevent this, it may be necessary with your dentist's help to monitor your infant's or young child's fluoride intake and keep it in check. That will depend in large part on where you live, as well as your child's hygiene and eating habits.
Like three-quarters of public water systems, your local utility may be adding fluoride to your drinking water. The amount is governed by federal guidelines, which currently recommend fluoride amounts of no more than 0.70 parts per million of water. The fluoride levels in your water could have an impact on your child's total fluoride intake. You can find out for sure how much fluoride is present in your water by contacting your water utility company.
Another major fluoride source is toothpaste and other hygiene products. You can control your child's fluoride exposure by limiting the amount of toothpaste on their brush. Children under two only need a “smear,” while those between two and six need only a pea-sized amount.
Processed foods can contain fluoride if fluoridated water was used in their production. In this case, replace as much of the processed food items in your family's diet as you can with fresh fruits, vegetables and other foods.
Along this line, if you have an infant you want to pay particular attention to feeding formula, especially the powdered form you mix with water. If you're concerned about the amount of fluoride in your water consider other infant feeding options. Besides breast-feeding in lieu of formula, you can also use ready-to-feed pre-mixed with water (usually lower in fluoride) or mix powdered formula with bottled water specifically labeled “de-ionized,” “purified,”Â “demineralized,” or “distilled.”
This can be a lot to keep up with but your dentist can advise you. Fluoride is still a potent weapon against tooth decay and a safeguard on your child's current and future dental health.
