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!

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.Â Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.
Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.
A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.
Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.
If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

Lifting weights helps to strengthen your muscles; calcium strengthens your bone density. Did you know that at Hibbeln & Kowal in Rochester Hills, MI, you can also strengthen your teeth? Dr. Debra Hibbeln and Dr. Mark Kowal offer crowns as a way of strengthening teeth for a number of their patients. The details of dental crowns are explained here.
What are dental crowns?
Sometimes called "caps," dental crowns are used as a way to restore form and function to a damaged or weakened tooth. Made from porcelain or various types of metals, crowns are hollow on the inside and fit over a natural tooth with a bonding cement to hold them in place. Dental crowns are a tried-and-true method of restoring teeth that have thousands of years of use. According to a reference book by Charles W. Dunn, scientists discovered hollowed out tooth-shaped pieces of gold, ivory and bone from the 8th century B.C. in what is now modern Tuscany. Amazingly enough, gold is still used as a crown material today!
Why do my teeth need crowns?
There are several reasons why your Rochester Hills dentist may recommend a crown. The most common reason is to strengthen a tooth after receiving a large filling or root canal. These treatments can remove enough of the tooth's structure that it can be vulnerable to more damage, so a crown covers the tooth to prevent any further problems. Natural teeth also receive crowns when a bridge is made to replace a missing tooth; the crowns bolster these teeth to keep the bridge stable. Cosmetic flaws, such as discoloration from medication, might also warrant the use of a crown to restore the appearance of the tooth.
You can be sure that at Hibbeln & Kowal, you'll receive "the royal treatment" when getting a crown or any other dental procedure. Contact our office in Rochester Hills, MI to learn more or schedule an appointment.
Moving your teeth to a more functional and attractive alignment is a big undertaking. You can invest months — even years — and a lot of expense to correct a bad bite. But all that effort could be for nothing if your teeth return to their original positions.
The very aspect of dental physiology that makes orthodontics possible can work against you in reverse. Your teeth are not actually rigidly fixed in the bone: they're held in place by an elastic gum tissue known as the periodontal ligament. The ligament lies between the tooth and the bone and attaches to both with tiny fibers.
While this mechanism holds the teeth firmly in place, it also allows the teeth to move in response to changes in the mouth. As we age, for example, and the teeth wear, the ligament allows movement of the teeth to accommodate for the loss of tooth surface that might have been created by the wear.
When we employ braces we're changing the mouth environment by applying pressure to the teeth in a certain direction. The teeth move in response to this pressure. But when the pressure is no longer there after removing the braces or other orthodontic devices, the ligament mechanism may then respond with a kind of “muscle memory” to pull the teeth back to where they were before.
To prevent this, we need to help the teeth maintain their new position, at least until they've become firmly set. We do this with an oral appliance known as a retainer. Just as its name implies it helps the teeth “retain” their new position.
We require most patients to initially wear their retainer around the clock. After a while we can scale back to just a few hours a day, usually at nighttime. Younger patients may only need to wear a retainer for eighteen months or so. Adults, though, may need to wear one for much longer or in some cases permanently to maintain their new bite.
Although having to wear a retainer can be tedious at times, it's a crucial part of your orthodontic treatment. By wearing one you'll have a better chance of permanently keeping your new smile.
