NotGettingaGoodNightsSleepYourDentistMayBeAbletoHelp

If you live an average lifespan, you'll spend more than 200,000 hours in blissful slumber. It's not a waste, though: You absolutely need this much sleep to maintain optimum physical and mental health. That's why the National Sleep Foundation recognizes each March as Sleep Awareness Month to highlight the obstacles to a good night's sleep. One such obstacle is obstructive sleep apnea (OSA)—and if you have it, we may be able to help you reduce the harm it may be causing you.

OSA is the blockage of the airway during sleep, usually when the tongue relaxes against the back of the throat. As the oxygen level falls, the brain arouses the sleeper to restore airflow. This only takes a few seconds before the person slips back into sleep, but it can occur several times an hour.

As this scenario repeats itself night after night, the person becomes deprived of the deeper stages of sleep they need to stay healthy. The long-term effect can even be life-threatening: Besides chronic fatigue and “brain fog,” there's also an increased risk of high blood pressure, disease or other serious health conditions.

But there are ways to reduce chronic OSA, the most common being a therapy known as continuous positive airway pressure (CPAP). A CPAP machine, prescribed by a medical doctor, consists of a small pump that streams pressurized air into the mouth through a hose and facemask; the increased air pressure in the mouth helps keep the airway open. It's a proven method, but not always a favorite with some patients who find it uncomfortable and restrictive to wear every night.

If you're in that camp regarding CPAP therapy, an alternative may be possible: oral appliance therapy (OAT), which dentists can provide. Worn in the mouth during sleep, this custom-fitted mouthguard-like appliance repositions the tongue so that it doesn't block the airway. There is a variety of mechanisms, but most involve a hinge that positions the lower jaw forward, which in turn pulls the tongue away from the back of the throat.

These less invasive OAT devices may be an alternative to CPAP therapy for people who have mild to moderate OSA and find CPAP machines difficult to use. If you've been diagnosed with OSA and CPAP therapy hasn't been a good fit for you, speak with us about an OAT device. It could help you overcome this common disorder and get the deep sleep you need for a healthy mind and body.

ThisOrthodonticDeviceCouldStopaPoorBiteFromDeveloping

“Orthodontic treatment” and “braces” almost seem like synonymous terms. But while braces certainly are orthodontic, it isn't the only tool in an orthodontist's toolkit.

A good example is a device is known as a Herbst appliance. It's used in situations where the upper jaw is outpacing the growth and development of the lower jaw during childhood. If not corrected, this could cause the top teeth to protrude abnormally beyond the lower teeth.

The Herbst appliance gently and gradually coaxes the lower jaw to grow in a more forward direction, thus “catching up” with the upper jaw. The top part of the device consists of two metal tubes hinged to small elastic bands, which are cemented to the cheek side of the upper back teeth (molars), one on either side of the jaw.

Two smaller tubes are attached in like fashion to the lower teeth, and then inserted into the larger tubes. As the lower jaw moves, the smaller tubes move within the larger to create pressure that gently pushes the jaw forward. Over time, this can sync the growth progress of both the upper and lower jaws, and reduce the chances of a poor bite.

For best results, a Herbst appliance is usually placed to coincide with a child's most rapid period of jaw growth, usually between 11 and 14. They could be placed as early as 8 or 9, however, in situations where the front teeth are already protruding well beyond the lips. In any event, the goal is to positively influence the growth of the lower jaw to alleviate or at least minimize the need for future orthodontic treatment.

As a fixed device, there's no need for a child or parent to tend to it as with other methods, like orthodontic headwear worn in conjunction with braces. A Herbst appliance can, however, alter the normal sensations associated with eating, swallowing and speaking, which may take a little adjustment time for the child. Wearers will also need to be extra vigilant with daily brushing and flossing because of a higher risk of tooth decay.

These, though, are minor inconveniences compared with the benefit of improved bite development. As such, a Herbst appliance could be a positive investment in your child's dental future.

Unless you're 6 years old and on speed dial with the Tooth Fairy, a loose tooth isn't a good feeling. It's also a sign something is wrong in your mouth. If you don't take prompt action, you may lose that tooth for good.

To begin with, teeth are held in place by an elastic tissue known as the periodontal ligament. The ligament lies between the tooth and bone and attaches to both through tiny fibers. The thing to note about the ligament is that it does allow for tooth movement, which serves as a “shock absorber” against the forces generated while biting and chewing.

But that movement is normally so slight, you won't perceive it. If you do, chances are there's a problem with the ligament attachment, which may have been damaged due to trauma or disease.

A hard blow to the face could certainly damage both the teeth and their attachments. But it can also happen if one tooth extends out farther than the rest and absorbs more stress during chewing. You could encounter similar damage if you attempt DIY orthodontics or wear tongue jewelry.

The more common source of ligament damage, though, is periodontal (gum) disease, usually caused by dental plaque, a thin film of bacteria and food particles left on tooth surfaces. If not treated, the infection can advance deeper into the gum tissues (and eventually the supporting bone), causing the ligaments to weaken and detach. In fact, a loose tooth is often a sign of well-advanced gum disease.

If you notice a loose tooth, you should make an appointment with us as soon as possible. Our first step is to ascertain the underlying cause and initiate any needed treatment. We may also want to splint a loose tooth to adjacent teeth to prevent excessive movement while the ligaments heal and reform their attachment to the tooth.

There will be times when a loose tooth is beyond repair. In that case, it may be best to remove the tooth and install a life-like replacement like a dental implant. But that's not inevitable. If at all possible and practical, we'll try to save your loose tooth.
