If you have a tooth that just doesn't look good because of decay or injury, a porcelain laminate veneer is probably a good way to make it look as good as it ever did — and maybe even better! Dental veneers are composed of thin layers of dental ceramic material. They essentially replace the original tooth enamel and require preparation of the tooth by removing a small amount of enamel to allow room for the placement of the veneer.

Recently, more and more dentists have been using minimal prep or prepless techniques that do not require this preparation. In such cases, the porcelain is bonded directly to the outer layer of the tooth's enamel. Highly skilled dental technicians can design a custom-fit veneer that feathers into the tooth just short of the gum line.

Prepless techniques cannot be used in all situations, but when they are used appropriately the results are beautiful and very stable. Should you get prepless veneers? The following is a list of advantages and disadvantages of prepless veneers.

Advantages of prepless veneers include:

• Tooth preparation or reduction is not needed, leaving the original tooth whole.
• They are not placed under the gum tissue, eliminating the possibility that the restorations negatively impact the gum tissue.
• They can be used to change the appearance of teeth that are too small or misshapen making the teeth look larger and eliminate unwanted spacing.
• They can be used to “lengthen” teeth that have been worn down by grinding.
• Since the underlying tooth has not been reduced, prepless veneers are reversible and practically risk-free.

Disadvantages include:

• There are many cosmetic situations in which they cannot be used, and traditional veneers (requiring preparation) must be used instead.
• Prepless veneers cannot be used in cases in which orthodontic treatment is recommended to move the teeth, such as improper tooth position, poor bite, or a poor facial profile.
• Since they are added on to existing tooth structure, they do not work for teeth that are relatively large or in a forward position in a smile.
• They do not usually work for lower teeth because of space restrictions.
• They cannot replace lost or damaged enamel.

Working with prepless veneers requires special skills and training. Please discuss our credentials and experience with us when you inquire about this technique. We can assess your specific situation and let you know whether restoration without the drill is appropriate for you.

The term “root canal” strikes fear into many dental patients. But rest assured that this procedure is the best solution to many severe dental problems. It can be pain-free and will actually relieve pain and suffering from infections and dental injuries.

Why would you need root canal treatment? This procedure becomes necessary when the pulp, the nerve tissue on the inside of a tooth's root, becomes inflamed or infected because of deep decay, or when it has suffered a severe injury as a result of an accident or blow to the mouth. The pulp is composed of living tissues including nerves and blood vessels.

Root canal treatment may be necessary if you have a wide variety of signs or symptoms. The pain can feel sharp or intense when biting down, or linger after eating hot or cold foods. Sometimes it can be a dull ache or there may be tenderness and swelling in your gums near the site of the infection.

After trauma, the pulp of a tooth can be exposed or damaged because a tooth has fractured or cracked, necessitating root canal treatment. And the procedure is often needed for permanent teeth that have been dislodged or knocked out.

What exactly is root canal treatment? Root canal treatment is also called endodontic treatment, from the Greek roots “endo” meaning “inside” and “odont” meaning “tooth.” During the procedure, the area is numbed to relieve pain. A small opening is created in the chewing surface of the tooth and very small instruments are used to remove dead and dying tissue from the inside. The pulp is needed during a tooth's growth and development, but a mature tooth can survive without it. The canal is disinfected and then sealed with filling materials. Sometimes root canal specialists use microscopes to work at an intricate level of detail on these tiny areas of the tooth's root.

By having root canal treatment, you prevent inflammation and infection from spreading from the root of a particular tooth to other nearby tissues. Infection can result in resorption, an eating away of the root and its anchoring bone, and you could lose your tooth or teeth. So please don't hesitate when we recommend this treatment. It's not as bad as you think, and you will feel significantly better afterwards.

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.

As the Boy Scouts say, it's best to be prepared. You may never have a traumatic injury to your teeth. But what if you do? Here are four questions and answers about such injuries and their treatment that may be helpful some day.

What are traumatic injuries?
We are talking about physical damage caused by a fall, an accident, or a blow to the face. The word trauma comes from the Greek root meaning “wound.”

A traumatic injury can also cause broken, cracked, or split teeth, or a fracture to the root of the tooth. A tooth may be dislodged from its proper position, pushed sideways, out of or deeper into its socket. It may even be completely knocked out of your mouth.

What should you do if your tooth is knocked out?
With proper treatment, the tooth can be restored to its original place. You must handle the tooth gently and seek professional help as soon as possible. Rinse the tooth in cold water if it is dirty, but do not use any cleaning agent. Avoid touching the root. While hurrying to your dentist, keep the tooth from drying out by keeping it in a container of milk or of your saliva, or by holding it in your mouth between gum and cheek. It is vital to keep the tooth's living tissues moist until it can be professionally assessed and replanted in its socket. If a tooth has been dislodged but not knocked out, it must be repositioned in its socket and may be stabilized with a splint.

Who can treat a tooth that is damaged by a traumatic injury?
A general dentist, an oral surgeon or an endodontist is trained to treat such injuries. An endodontist is trained to treat the root canal(s) inside a tooth. The word comes from “endo” the Greek word for “inside,” and “odont,” the word for “tooth.” After a tooth is replaced in its socket and stabilized, root canal treatment is often needed.

What is root canal treatment?
A tooth is composed mostly of dentin, a living tissue. The top part or crown is covered by hard mineralized enamel. The soft tissue inside the tooth, the pulp, contains blood vessels, nerves and connective tissues. It extends from the crown to the tip of the roots. Treatment of dental pulp injuries is called root canal or endodontic treatment and is usually needed to treat teeth that have been dislodged or fractured.

Even with all the medical know-how we possess at the dawn of the 21st century, complete tooth loss is still a big problem. In this country, more than a quarter of all adults between ages 65 and 74 have lost all of their teeth. For these individuals, removable full dentures are often still used as an affordable and effective way to replace missing teeth.

Success with dentures originates from a collaboration among dentist, laboratory technician, and, of course, the denture-wearer. Creating false teeth that look natural is as much an art as it is a science. We take a number of steps to make sure you will get the best results. These include:

• Positioning the teeth. Using facial landmarks and photographs of how you used to look before your teeth were lost helps us determine where to place each tooth and how the upper and lower teeth should line up in relation to each other. For example, we will consider what size the teeth should be; how close to the lip they should be; and how much space should exist between the upper and lower teeth when they are at rest.
• Simulating natural gums. If you are someone with a “high lip dynamic” (a lot of gum shows when you smile), it is particularly important to simulate real gum tissue in a set of full dentures. Fortunately, there are many colors and textures available to create a realistic effect. Again, photographs can be helpful in achieving this.
• Balancing the bite. We must make sure that your upper and lower dentures come together in a way that facilitates normal biting, chewing, and speech.

As a denture wearer, you will need to visit our office regularly to make sure the gum tissue and bone upon which your dentures rest stay healthy. It's common to see a gradual loss of bone in people who wear dentures at a rate that varies from person to person. This bone loss can affect the fit of your dentures and lead to other health problems, which we can address if we are monitoring you on an ongoing basis.
