For over a century now, health providers have depended on blood and urine samples to diagnose many forms of disease. Very soon, though, we may routinely use a different bodily fluid that's easier and cheaper to collect: saliva.
Secreted by six hundred or more glands in the mouth, saliva performs a number of important functions for digestion and overall oral health. Saliva lubricates the mouth to make food easier to swallow. Its enzymes begin the digestion process breaking down food even before we swallow. It also helps wash out food particles that could build up as plaque on the teeth and harbor disease-causing bacteria.
In terms of dental health, its greatest role is as a neutralizer of food acid. It's natural after we eat for the acid levels in the mouth to rise above normal. If acid remains in contact with enamel for an extended period of time it can soften the enamel's minerals and make it easier for them to erode. Within thirty minutes to an hour after eating, saliva neutralizes acid and restores the mouth's normal pH level. Saliva also contains calcium and phosphate materials, which helps restore some of the minerals the enamel may have lost from the acid contact.
But we're discovering saliva can do even more: we can now use it as an indicator for certain conditions in the body. Like blood or urine, saliva contains molecules that can serve as biological markers for different types of disease. By employing devices calibrated to detect these markers, we can use saliva to uncover cancer, diabetes or other systemic conditions.
As these particular devices are manufactured and become more available, the use of saliva for disease diagnosis will rise. In the future, you may not need a trip to the bathroom or wince at a needle stick — a swab of your saliva will do!

If you’re considering different options for tooth replacement, dental implants are likely high on your list. Implants have a proven reputation for both durability and life-like appearance that can restore mouth function and revitalize your smile.
There is one aspect concerning implants, however, which gives people pause — the surgical procedure required to place the implants in the jawbone. If you’re leery about undergoing this procedure we can put your mind at ease — for most patients implant surgery is a minor, pain-free process with little discomfort afterward.
While there are variations in style, implants generally have two major components: a titanium post that’s implanted into the jawbone and a permanent life-like crown that’s affixed 6 to 12 weeks after implant surgery. Titanium is the metal of choice because of its affinity with bone cells; over time bone will grow to and attach itself around the implant, a process known as osseo-integration. The metal post is normally spiral in shape, allowing it more surface area for bone to adhere to.
In the beginning of the procedure we administer local anesthesia to fully numb the area before proceeding. After accessing the bone through tiny incisions in the gum tissue, we create a small channel in the exposed bone. A surgical guide may be used to prepare the precise location for the implant with a series of drilling sequences that increases the channel until it matches the implant size. While this takes place, you should only feel a mild vibration and a little pressure from the drill.
The implants are then removed from their sterile packaging and placed immediately into the prepared site. The gum tissues are then sutured into place with self-absorbing sutures. Most people have only mild discomfort after the surgery that can be managed with a prescription-strength non-steroidal anti-inflammatory drug like ibuprofen. We may also prescribe antibiotics and other care instructions to ensure successful gum tissue healing.
With proper planning and precise implant placement by skilled hands, implant surgery is an easy and uneventful procedure. And, with your new crowns in place, your new, beautiful smile will make the experience a distant memory.

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.

Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.

Dental caries (tooth decay) is a leading cause of tooth loss. But with prompt diagnosis and care we can often stop it before it causes too much damage.
The traditional treatment approach is simple: remove all diseased tooth structure and then restore the tooth with a filling. But this otherwise effective treatment has one drawback: you may lose significant healthy structure to accommodate a suitable filling or to make vulnerable areas easier to clean from bacterial plaque.
That's why a new treatment approach called minimally invasive dentistry (MID) is becoming more common. The goal of MID is to remove as little of a tooth's natural enamel and dentin as possible. This leaves the treated tooth stronger and healthier, and could reduce long-term dental costs too.
Here's how MID could change your future dental care.
Better risk assessment. MID includes a treatment protocol called caries management by risk assessment (CAMBRA). With CAMBRA, we evaluate your individual tooth decay risk, including oral bacteria levels, the quality of saliva flow to neutralize mouth acid, and sugar consumption. We then use our findings to customize a treatment plan that targets your areas of highest risk.
New detection methods. The real key to fighting tooth decay is to find it before it can destroy tooth structure with the help of new diagnostic technology. Besides advances in x-ray imaging that provide better views with less radiation exposure, we're also using powerful dental microscopes, lasers and infrared photography to show us more about your teeth than we can see with the naked eye.
"Less is More" treatments. In contrast to the dental drill, many dentists are now using air abrasion rather than a dental drill to remove decayed tooth material. Air abrasion emits tiny material particles within a pressurized air stream that leaves more healthy tooth structure intact than with drilling. We're also using new filling materials like composite resin that not only resemble natural tooth color, but require less structural removal than other types of fillings.
Using MID, we can treat tooth decay while preserving more of your natural teeth. This promises better long-term outcomes for future dental health.
