Dentistry has ventured into the new area of sleep medicine by helping snorers — and their exasperated sleeping partners — with custom-made anti-snoring devices. These oral appliances, which resemble orthodontic retainers or sports mouthguards, keep the snorer's airway clear and the bedroom quiet. To see how they work, you have to understand the mechanics of snoring.

Snoring occurs when the upper airway (back of the throat) becomes blocked by the tongue or other soft-tissue structures, such as large tonsils or a long soft palate. The vibrating of these obstacles creates the sound we call snoring.

Snoring is often worse when sleeping on one's back because that position encourages the lower jaw to fall back and the tongue to close off the airway. This is where Oral Appliance Therapy comes in. These custom-fitted devices are designed to keep the upper airway open during sleep by pulling the lower jaw forward, which in turn brings the tongue away from the throat. Dentists, and our office in particular, are the only source for Oral Appliance Therapy.

People who snore should have a thorough examination to rule out Obstructive Sleep Apnea (OSA), a potentially dangerous condition in which airflow can be cut off completely for 10 or more seconds (“a” – without; “pnea” – breath), reducing blood-oxygen levels. Chronic, loud snoring is a common finding with OSA.

Please remember that sleep is an integral part of health and well-being. In fact, we spend about a third of our lives doing it. If you are snoring or have any sleep-related breathing disorders that are waking you or your bed partner, be sure to tell our office. There are plenty of examples of the havoc wreaked by sleep-deprived individuals. Remember the Exxon Valdez?

Supermodel Christie Brinkley has a one-in-a-million smile, but she is just one of millions who have benefited from today's preferred tooth-replacement technique: the dental implant. In a wide-ranging interview, Brinkley told Dear Doctor magazine about a helicopter accident she suffered while back-country skiing.

“I fractured two molars in the back of my mouth and I had to get two dental implants,” Brinkley told the magazine. “I am grateful for the dental implant technology that feels and looks so natural.”

You might think it serves little purpose to replace a missing back tooth that was barely visible in your smile to begin with — especially if you don't spend a lot of time posing for magazine covers. But this is actually not the case. Your molars are extremely important for chewing and even for maintaining a more youthful appearance.

Dentists generally agree that losing posterior (back) teeth can have many consequences for the remaining teeth and their surrounding structures, i.e., bone and gums. If back teeth are missing, the front teeth end up bearing more stress than they were built for. And there are certain things that happen when any tooth is lost, whether front or back, that can affect function and appearance.

For one thing, when a tooth is lost the adjacent teeth tend to drift into the empty space or tip towards it. This can adversely affect your bite. Too much shifting can render a tooth basically useless and also leave it more vulnerable to gum disease.

Another complication is the loss of tooth-supporting bone that inevitably occurs when teeth are lost. When a tooth comes out, the bone under it actually begins to melt away. Since back teeth support the vertical dimension of the face, their loss can cause what's known as “bite collapse” — a reduction in facial height that becomes increasingly noticeable over time and can make you look older.

A dental implant can prevent all of these things, while providing you with a replacement that looks and feels just like the tooth you lost.

On the day when braces come off, most people feel that their orthodontic treatment is over. When they are then asked to wear retainers, they may wonder what this additional requirement will accomplish. Wasn't the work of moving their teeth to desired positions already completed? To understand the answer to this question, you need to understand how orthodontics works.

How does orthodontic treatment remodel your smile?

Although they give the appearance of being stable and unmoving, teeth and their surrounding structures (gums, jawbones, and ligaments) are living tissues and are actually in a constant state of change.

Teeth are rooted in bone and are attached by a fibrous tissue called the periodontal ligament (from peri meaning around and odont meaning tooth). One side of the ligament attaches to the cementum (part of the tooth's root) and the other side is attached to the bone, with the tooth suspended in between.

These tissues are constantly remodeling themselves, but pressure from the lips and cheeks on one side and from the tongue on the other create a balance that keeps the teeth suspended in the same location. When mild forces are placed on the teeth, such as the forces from the wires used in orthodontic treatment, the tissues slowly adapt and rebuild, resulting in a new position for the teeth.

What are retainers?

Orthodontic retainers are devices usually made of a clear plastic section that is fitted to the roof of the mouth, with thin wires that fit over the teeth.

What is the purpose of retainers?

The remodeling process keeps going after the orthodontic treatment stops, so time is needed for the teeth to reach a new balanced state. The retainer stabilizes them in their new position so that bone and ligament can reform around the teeth and hold them there. This works well for adolescents, whose jaws are in a state of growth, but adults may need outside assistance to stabilize their teeth for a longer time. They may be asked to wear retainers indefinitely to make sure their teeth do not move from their new positions.

What happens if you don't wear your retainers?

If you don't wear your retainers, your teeth are likely to return to the positions they had prior to your orthodontic treatment. This can happen fairly rapidly, underscoring the importance of wearing retainers as instructed.

What are the different types of retainers?

Most retainers are removable devices as described above. For people who require long-term use of retainers, thin retainer wires can be bonded to the inside surfaces of their front teeth. Such wires are usually left in place for several years, relieving them of the need to remove and replace their retainers.

While the goal of restorative dentistry is to return all of the destroyed or lost dental tissues of the teeth to full form (shape) and function, when you blend this goal with the artistry of cosmetic dentistry, the results can be dazzling. Today's modern techniques and materials enable replacement of missing tooth structure that allows bonding directly to the tooth so that it not only is an exact color match but also actually strengthens the tooth. And tooth-colored fillings are not just for front teeth. They can dramatically improve the appearance of all teeth — even your back molars — so that it appears you've never had tooth decay at all!

All of this is accomplished through the use of either tooth-colored dental porcelain or composite resins. Porcelains are a form of ceramic material formed by the action of heat. They are available in many colors and shades made from a powder corresponding to the primary color of the natural tooth structure that is mixed with water and placed into an oven for firing (hence their ceramic nature). When built up in layers by highly trained dental ceramicists, they can be made to mimic the exact natural translucency, staining and contours of tooth enamel.

Dental composite resins are the most common materials used for tooth-colored adhesive restorations today and have properties similar to tooth structure. They consist of resin or special plastics and fillers that are made of silica, a form of glass. The fillers give the composites wear resistance and translucency (see through properties).

It is important to note that besides providing the appearance of beautiful teeth, properly restored teeth function and wear better. But most important to you, they appear indistinguishable from natural teeth! Furthermore, scientific studies and clinical experience have validated their use as both safe and predictable. In fact, these techniques are also suitable for children's teeth and can incorporate fluoride to reduce decay. Together, all of these changes have so significantly impacted the way modern dentistry is practiced that many believe we may have entered into the so-called “post-amalgam (silver metal-colored dental fillings) era.”

Temporomandibular Disorder (TMD), which was formerly known as Temporomandibular Joint Disorder (TMJ), is an interesting condition because it can be hard to diagnose and often mimics many other conditions. It arises when there are problems inside the temporomandibular joint, and the muscles attached to it, causing pain. When treating TMD, we typically start by relieving the symptoms of pain and discomfort with heat, mild pain medications, a diet of soft foods, and some simple jaw exercises. We feel that it is critical to address your pain issues as soon as possible before preceding any further with treatment.

Once we have provided some pain relief and after having completed a thorough history and examination, we can move to the next phase of treatment. This may include the introduction of a bite guard or some form of oral appliance therapy. A bite guard is an unobtrusive yet rigid plastic horseshoe-shaped appliance that fits snuggly over the biting surfaces of the upper teeth. When in place and properly adjusted, this custom-made appliance allows your muscles and therefore jaw joints to relax. And it will prevent you from grinding your teeth, another contributing factor to TMD. We will probably ask you to wear it when sleeping or in times when you are feeling stressed when clenching or grinding habits may be active. We may also suggest that you obtain some relaxation therapy and/or biofeedback from a licensed therapist, as this can prove helpful in treating TMD.

If you have suffered from frequent jaw pain in the past and suspect that you may have TMD, please let us know so that we can address it at your next appointment. Or if you are currently in constant or severe pain, contact us immediately to schedule an appointment.
