If you cringe at the appearance of your less than pearly whites when you look in the mirror, you are not alone. A frequently requested cosmetic procedure, teeth whitening is a very successful and relatively inexpensive way to enhance your smile. We can determine which whitening treatment will work best for you after performing a basic oral examination in our office. When will it work and when won't it? Here's some background:

Teeth most commonly become stained or discolored due to surface (extrinsic) changes, the most common of which are dietary and smoking. Foods including red wine, coffee, and tea can cause extrinsic staining. Teeth can also commonly become discolored or stained due to intrinsic (internal) reasons, such as changes in the structure of enamel or dentin or by incorporation of chromogenic (color generating) material into tooth tissue during formation or after eruption.

1. Toothpastes that claim to whiten teeth are only effective in removing plaque and other surface stains. Although most of these products contain mild abrasives that remove the plaque, they aren't capable of changing the underlying color of stained teeth.
2. Tooth polishing by your dentist or dental hygienist is effective in removing superficial staining, but will not change tooth color.
3. Teeth whitening systems work by bleaching, generally with the use of hydrogen peroxide. Using bleaching gels in custom made trays or whitening strips can be done at home, but is slow and the changes are gradual. We can perform quicker and more effective “power bleaching” in our dental office when precautions can be taken to ensure safety due to the higher concentrations of bleaching gels used. Teeth with intrinsic (internal) staining may need internal bleaching to whiten them and this can only be done in the dental office.
4. Teeth whitening results fade over time, but optimally last from six months to two years. Taking care of your newly whitened teeth by avoiding the foods, beverages, and habits that cause staining will help them remain whiter for longer.
5. If you have had previous cosmetic dentistry performed, including the placement of composite restorations, porcelain veneers, or crowns, teeth whitening may not be for you. Bleaching agents have little to no effect at all on the materials used to create these restorative products.

Damaging the crown of a tooth (the part of the tooth that is visible above the gums) is the most common type of dental injury. The tooth may be broken or chipped. It is good to be prepared by knowing how such cases should be treated.

What is the first thing to do if my tooth is chipped or broken?
If fragments broke off the tooth, try to find and save them. They can probably be reattached to the tooth by bonding.

Does a chipped or broken tooth hurt?
The tooth may be sensitive to touch, hot and cold. Depending on the type of injury and how much of the tooth's inner surface is exposed, there may also be pain.

How long can I wait before getting treatment?
Get treatment right away, within 12 hours if possible. Teeth with crown fractures can be treated within 12 hours without affecting long-term outcomes.

What types of treatment may be used?
The treatment recommended depends on the tooth and the type and severity of the injury. Exposure of a tooth's inner pulp can be treated by a pulpotomy (partial pulp removal) technique. Front teeth can be temporarily restored with special cements, or the original tooth fragments may be reattached by bonding. Composite resin bonding may be used to restore the tooth's original appearance and function. Composites can be made in a wide range of tooth colors and can match the original tooth almost exactly.

Is treatment different if the damaged tooth is a primary (baby) tooth?
Chipped or broken primary teeth are generally treated similarly to permanent teeth. The treatment depends on the extent of the injury and damage to the tooth. Treatment of fractured primary teeth also depends on the proximity of the injured tooth to the permanent tooth beneath it, which will ultimately replace it. If a fractured primary tooth cannot be saved, it may be removed.

What if my tooth is loosened but not broken?
If the tooth is loosened but not cracked, broken or chipped, no dental treatment may be required. However, we will collect baseline clinical and x-ray information and keep an eye on the tooth or teeth in the future. We will need to check the tooth during recall visits to see whether the dental pulp is still living or whether it has died as a result of its injury. The latter condition can lead to a variety of problems and will require treatment.

Getting enough sleep is necessary for good health. We all know how energetic we feel when we are sleeping well at night. Yet, many of us do not feel rested, even after seven or eight hours of sleep. Let's answer some common questions about snoring and sleep apnea, problems that are often called sleep related breathing disorders (SRBD).

What is the purpose of sleep?
Scientists know we need sleep, at a particularly deep level, to be rested, but they are not sure why we need sleep. Sleep may have evolved as a way to conserve energy in the body, to conserve food supplies, or to reduce our risk during darkness. Sleep appears to give the brain a chance to store and organize its information and the body a chance to recuperate. Sleep studies have shown that in order to get the full benefits of sleep we need to sleep long and deeply enough to enter into a series of sleep cycles including Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM) sleep.

What kinds of problems get in the way of the type of sleep we need?
There are eight main categories of sleep disorders, but the ones affecting the largest numbers of people are insomnia, SRBD, and Circadian Rhythm Sleep Disorders. SRBDs include snoring and Obstructive Sleep Apnea (OSA), which is a serious health problem.

How do I know if I have OSA or another SRBD?
Often, your bed-partner will tell you that you snore. Chronic loud snoring is an indicator of OSA. To make a diagnosis your physician must take a thorough sleep and medical history. The diagnosis may then be confirmed by a study in a sleep lab.

What causes sleep apnea or OSA?
Snoring and OSA happen when your tongue and other soft tissues in the back of your throat collapse backwards and block airflow through your upper airway or windpipe. You may briefly awaken as many as 50 times per night because of these breathing lapses. These brief awakenings, called micro-arousals, keep you from reaching the deep stage of sleep your body needs.

What are the treatments for sleep apnea?
Treatments include CPAP therapy, in which patients wear a mask while sleeping. The mask pushes air through the airway, keeping it open. In Oral Appliance Therapy (OAT) patients wear a device that moves the lower jaw forward, allowing more room for air to move down the airway. Oral surgical procedures and orthodontic approaches also have the goal of moving the tongue away from the throat. These are all treatments that can be carried out by a dentist who has training and experience in treatment of sleep disorders.

Periodontal (gum) disease, though it may be invisible to everyone but your dentist, can have a powerful effect on your entire body. Not only is it dangerous to your teeth and jaws, but it can increase your risk of heart attack and stroke, cause preterm births in pregnant women, and affect blood sugar control in diabetics.

Diabetics are our subject for today. Symptoms of diabetes include abnormally high levels of glucose (a form of sugar) in the blood, leading to frequent urination, excessive thirst, blurred vision, unexplained weight loss, and loss of energy. The disease can also cause severe complications in various parts of the body.

Normally, glucose, your body's main energy source, is kept under control by a hormone called insulin, which is made by an organ called the pancreas. In type 1 diabetes, a person's pancreas does not produce enough insulin to deal with all the glucose in his or her blood. In type 2 diabetes — a condition related to increased age, physical inactivity, overweight, and heredity — the pancreas may produce enough insulin, but the body is not able to use it effectively. This condition is called insulin resistance.

People with type 1 diabetes need insulin to survive. Type 2 may be treated with exercise, diet, medications, and insulin supplements.

Serious complications of diabetes range from kidney failure, blindness, and nerve damage to infections that do not heal, gangrene and amputation of limbs.

Diabetes and periodontal disease seem to have reciprocal effects on each other. Diabetics are more likely to have periodontal disease than non-diabetics; and those with periodontal disease are likely to face worsening blood sugar control over time.

Periodontal disease (from “peri”, meaning around and “odont”, meaning tooth), is caused by dental plaque — a film of bacteria that settles on your teeth and gums every day. It's what you remove with daily brushing and flossing. Any bacteria that remain cause inflammation, which can lead in the worst cases to loss of bone and eventual loss of teeth.

The close relationship of diabetes and periodontal disease probably results from changes in the function of immune cells responsible for healing. Inflammation is a part of normal wound healing — but chronic or prolonged inflammation can destroy the tissues it was meant to heal. This may be a major factor in the destructive complications of diabetes.

Many of these complications begin in the blood vessels. Like the eyes and the kidneys, gum tissues are rich in blood vessels. Gum tissues are also under constant attack from bacteria. If you are a diabetic, effective plaque control, along with regular professional dental cleaning, can have positive effects not only on periodontal disease, but also on control of your blood glucose level.

There's a lot to like about dental implants, today's state-of-the-art tooth-replacement system. We consider them the best choice for replacing missing teeth because implants are:

Healthy
You may not realize this, but when a tooth is missing, the bone underneath it begins to melt away. That's because bone needs constant stimulation to rebuild itself and stay healthy, and it receives this stimulation from teeth. It's a delicate balance that's disrupted by the loss of even one tooth. Because implants are made of biocompatible titanium, they actually fuse to the bone and prevent bone loss.

Strong
The fusion of implant to bone is an extremely solid connection. Not only does it offer a strong replacement for a missing tooth, but it can also offer support to other tooth-replacement methods such as fixed bridges or dentures. By themselves, these other methods would not preserve bone and might even hasten its loss in the case of dentures. But with implants, bone-loss is prevented — as is embarrassing and uncomfortable slippage of dentures.

Aesthetically Pleasing
When you receive your implant, it is left alone for a few months to complete the fusion process described above. Then it is topped with a crown made of a realistic tooth-like material. The result is so convincing as a tooth replacement, only you and your dentist may be able to tell it's not a natural tooth.

Long-Lasting
Dental implants have an amazing success rate — over 97%. And once they fuse to the jawbone, they should never need replacement. In fact, they will likely outlast the crowns to which they are attached, but this is not a problem. Implant crowns are precision components that detach for easy replacement, should the need arise.

Economical
Implants have a higher initial cost than other forms of tooth replacement, but when you consider how long they last, they are very economical. Consider it an investment in your health, appearance and self-confidence.

If you have any questions about dental implants, contact us today to schedule an appointment for an implant consultation.
