Although techniques and materials have changed, dentists still follow basic principles for treating tooth decay that date from the late 19th Century. And for good reason: They work. These principles first developed by Dr. G.V. Black—the "father of modern dentistry"—are widely credited with saving millions of teeth over the last century.
One of the most important of these treatment protocols is something known as "extension for prevention." In basic terms, it means a dentist removes not only decayed tooth structure but also healthy structure vulnerable to decay. But although effective in saving teeth, practicing this principle can result in loss of otherwise healthy tissue, which can weaken the tooth.
But with new advances in dentistry, decay treatment is getting an overhaul. While Dr. Black's time-tested protocols remain foundational, dentists are finding new ways to preserve more of the tooth structure in a concept known as minimally invasive dentistry (MID).
Better diagnostic tools. Because tooth decay can ultimately infect and damage the tooth's interior, roots and supporting bone, the best way to preserve more of the tooth structure is to treat it as early as possible. Now, new diagnostic tools like digital x-rays, microscopic magnification and optical scanning are helping dentists detect and treat decay earlier, thus reducing how much tissue is removed.
Better prevention methods. Oral hygiene and regular dental care are our basic weapons in the war with tooth decay. In addition, utilizing topical fluoride in combination with a milk-derived product called CPP-ACP dentists can get more of the cavity-fighting organic compound into the tooth enamel to strengthen it against acid attack.
Better treatment techniques. Using air abrasion (a fine particle spray that works like a miniature sandblaster) and lasers, dentists can now remove decayed structure with less harm to healthy tissue than with a traditional dental drill. And new, stronger dental fillings like those made with composite resins require less structural removal to accommodate them.
With these innovative approaches, dentists aren't just saving teeth, they're preserving more of their structure. And that can improve your overall dental health for the long-term.

Calling someone "long in the tooth" is an unflattering way of saying they're getting old. The phrase refers to the effects of gum recession, in which the gums pull away from the teeth and cause them to appear longer. The problem, which makes the teeth vulnerable to disease as well as look unattractive, is a common problem for older people.
The most common cause for gum recession is periodontal (gum) disease. Bacteria and food particles, which make up dental plaque, trigger an infection. The deposits of plaque and calculus (hardened plaque) continue to fuel the infection as it continues to weaken gum tissue attachments.
As a result, the gums begin to lose their attachment to the teeth and pull away, exposing the root areas normally covered by the gums. Unlike the enamel-protected crowns (the parts of teeth you can see), the root is covered by a thin layer of material called cementum.
Although cementum offers less protection than enamel, this normally isn't a problem because the gums also act as a barrier against bacteria and other harsh aspects of the mouth environment. But without gum coverage, the root area becomes vulnerable to disease and is more prone to painful sensitivity.
Because gum disease is the main culprit, you can reduce your chances of gum recession by keeping your teeth clean of plaque through brushing and flossing, and regularly undergoing professional cleanings. If gum disease does occur, it's important to seek treatment as soon as possible: The earlier it's treated the more likely that any recessed gum tissues can regenerate.
If the recession is extensive, however, you may need clinical intervention to assist with its regrowth. This can be done by grafting tissue at the site that then serves as scaffold for new tissue to grow upon. Though effective, these microsurgical techniques are quite complex and involved.
So, if you suspect you have gum disease or recession, see your dentist as soon as possible for a full examination. It may be possible to restore your gums and enhance your smile.

Bite problems aren't limited to teeth simply out of position. The problem could be some teeth aren't there—visibly, that is. They still exist below the gums and bone, but they've been crowded out and blocked from erupting. We call this condition impaction.
Any tooth can become impacted and affect the bite, but a person's smile suffers more if it involves visible front teeth. This is especially so if the teeth in question are upper canines or "eye teeth"—the smile doesn't look normal without these pointed teeth on either side of the central and lateral incisors.
Impacted teeth can also contribute to more than a cosmetic problem: they're more susceptible to abscesses (pockets of infection) or root damage both to themselves or neighboring teeth. To minimize these potential health issues, we'll often remove impacted teeth surgically (as is often done with wisdom teeth).
But because of their important role in not only appearance but also bite function, we may first try to assist impacted canines to fully erupt before considering extraction. It takes a bit of orthodontic "magic," but it can be done.
Before we can make that decision, though, we want to precisely locate the impacted teeth's positions and how it may affect other teeth. This initial evaluation, often with advanced diagnostics like CT scanning or digital x-rays, helps us determine if the impacted teeth are in a workable position to save. If they're not, we may then need to consider removing them and ultimately replacing them with a dental implant or similar restoration.
But if their position is workable and there are no other impediments, we can proceed with helping them erupt. To do this we'll have to first expose them by creating a small opening in the gums through minor surgery. We then bond a small bracket to the tooth, to which we'll attach a small chain that we then attach to orthodontic braces. This enables us to exert continuous pressure on the tooth.
Over time, the pressure coaxes the tooth to erupt. We may still need to apply other forms of orthodontics and cosmetic procedures, but using this procedure to rescue impacted canines can produce a healthier and more attractive smile.
