Long ago dental work could be painful and stressful—often for both patient and practitioner. Thankfully, that time is long past: today, most procedures are painless in large part due to local anesthesia.
Local anesthetics are numbing substances applied to specific areas of the body like the teeth and gums to temporarily block pain during a procedure. And because they only affect a localized area of the body, you remain conscious and alert throughout the procedure.
To achieve the level of numbing necessary for dental work, we often need to deaden the gums using a needle to deliver the anesthetic. But then this poses a secondary pain concern—the needle stick itself.
Again, topical anesthesia comes to the rescue in the form of a swab, patch or spray applying an anesthetic directly to the top layer of the gums at the injection site. This numbs the area and prevents you from feeling the needle stick. It's highly probable, therefore, that from start to finish you won't feel any discomfort during your dental work except perhaps for a little pressure.
Local anesthesia truly is a game changer for dental care—and not just for the patient. A dentist who's concerned about their patient's comfort level may work hurriedly to complete a procedure. But if their patient is relaxed, the dentist can work calmly and methodically. The result is better, more focused care.
For all its improvements in the patient experience, though, there has been one consistent complaint—the numbness that often lingers for a while after the procedure is over. But there have been advances in recent years that have helped reduce this irritation: new anesthetic agents (even some that can reverse the anesthetic effect) and fine-tuned dosages can help keep residual numbing to a minimum.
Not all procedures like routine teeth cleanings or enamel shaping require anesthesia. But when it's appropriate, local anesthesia can make your next dental visit much more pleasant.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

For whatever reason, you’ve put off replacing a missing tooth for awhile. Now you want to fill that empty gap in your smile with a dental implant restoration.
But if your tooth’s been missing for a long time, there could be a problem with space. This is because the teeth on either side of the space may have gradually drifted into it, leaving no room for the implant. You could need orthodontic work first to return these teeth to their proper position.
We could use braces, metal orthodontic devices with wires threaded through brackets bonded to the teeth that are then anchored, usually to back teeth. The orthodontist uses elastics or springs as well as possibly incrementally tightening of the wire against the anchors. These techniques create pressure or tension on the teeth for the desired direction of movement. The teeth’s natural mechanism for movement does the rest.
But while effective, braces can be quite noticeable, an embarrassing thought for many adults having to wear them over several months of treatment. But there may be an alternative: clear aligners, a succession of slightly different plastic trays usually worn in two-week intervals. Sequentially wearing each tray gradually moves the teeth to their desired positions.
Though not appropriate for all bite situations, clear aligners have a number of benefits when they can be used. They’re nearly invisible to others and can be removed for hygiene tasks or rare special occasions. What’s more, the orthodontist may attach a temporary prosthetic (false) tooth to the trays to camouflage the missing space during treatment.
There’s one other issue you may have to deal with: if your tooth loss was related to periodontal (gum) disease, the gums and underlying bone may be in poor condition. In fact, substantial bone loss could rule out an implant altogether. But we may be able to remedy both gum and bone deficiencies through grafting or plastic surgery. It may be possible to regenerate enough bone to support the implant; and surgically repairing your gums will help ensure the implant appears natural.
If you have problems like these, don’t give up on your restoration goal just yet. With some orthodontic and dental work ahead of time, we may still be able to make implants a reality for you.
Dental veneers, thin layers of porcelain bonded to chipped, stained or slightly crooked teeth, are an effective and affordable way to transform your smile. Their color, translucence and shape blend so well with the rest of your teeth that it's often difficult to tell them apart.
But traditional veneers have one drawback: although they're less than a millimeter in width, they can still appear bulky on unprepared teeth. To help them look more natural, we often have to remove some of the enamel layer from the tooth surface. Enamel doesn't grow back, so this alteration is permanent and the prepared teeth will require a restoration from then on.
But you may be able to avoid this—or at least keep the alteration to a minimum—with no-prep or minimal-prep veneers, two new exciting choices in cosmetic dentistry. About the width of a contact lens, we can bond these much thinner veneers to teeth with virtually no preparation at all or, in the case of a minimal-prep veneer, needing only an abrasive tool to reshape and remove only a tiny bit of the enamel.
These ultra thin veneers are best for teeth with healthy enamel, and can be placed in as few as two appointments. And besides being less invasive, the procedure is reversible—we can remove them and you can return to your original look without any follow-up restoration. One caveat, though: because of the strong bonding process used, it's not always easy to remove them.
Although their thinness makes it possible to avoid or minimize alterations, there are some dental situations like oversized teeth that may still require extensive tooth preparation. With some poor bites (malocclusions) orthodontic treatment to straighten the teeth may also be needed first.
All in all, though, no-prep or minimal-prep veneers could help you avoid the permanent tooth alteration that usually accompanies their thicker cousins. What's more, you'll have the beautiful, transformed smile that veneers can achieve.

There are an assortment of techniques and treatments in an orthodontist's toolkit, braces being the most common and best known. Of course, there wouldn't be any tools at all if teeth couldn't move naturally.
Teeth aren't directly connected to the jawbone. An elastic tissue called the periodontal ligament lies between each one, with tiny fibers attaching to the tooth on one side and to the bone on the other. The ligament's elasticity and other qualities allow micro-movements of the teeth as we bite.
The ligament can also adapt to changes in the mouth and teeth by allowing the teeth to move to different positions. That's the basic concept behind braces: we thread a thin wire through brackets attached to the teeth, which we then attach to anchor points (usually back teeth not intended to move) and apply tension to it. Gradually over time, the target teeth move.
But what if your malocclusion (poor bite) is more complicated or the back teeth can't supply enough anchorage for moving the intended teeth? That's where we take advantage of other sources of anchorage.
One such source is the patient's skull, which we can make use of through special headgear worn a few hours a day. The device consists of a strap under tension that runs around the back of the head or neck to a wire housing attached to brackets on the target teeth. If you want to “pull” the teeth forward, the strap would come over the chin, forehead or a combination of both.
We may sometimes want to isolate some teeth to move without moving nearby teeth, such as moving front teeth backward to close a space without affecting teeth further to the rear. We can create a separate anchor point in the jaw with a TAD or temporary anchorage device.
TADs are tiny screws made of stainless steel inserted temporarily into the bone. We loop an elastic band over the TAD on one end and to a bracket or tension wire attached to the target teeth on the other. When we've achieved the teeth's new position we can easily remove the TAD from the bone.
These various tools make it possible to correct difficult or complex malocclusions. They may not always look attractive, but they'll help ensure the final result is.
