Are the following statements true or false?
Thumb sucking in children may cause problems with their teeth later on.
Prolonged thumb sucking may be responsible for many problems with the bite. The constant pressure of the thumb itself can create a gap between the top and bottom teeth in front, a condition called an “open bite.” It also reinforces the habit of using the “tongue thrust” motion in swallowing, where the tongue is positioned between top and bottom teeth. This habit may also block full eruption of the front teeth.
Infants and young children swallow exactly the same way that adults do.
When they swallow, young children use what is called the “infantile swallowing pattern.” In this method, which begins before their teeth have erupted, the tongue is thrust forward in the mouth, sealing and supporting the lips. In adult swallowing, the tongue touches the roof of the mouth, behind the front teeth. The transition from the infantile method usually happens naturally, by around age 4.
Most open bites result from the habit of positioning the tongue too far forward.
Failure to transition between the infantile and adult swallowing pattern is believed to be the cause of most open bites. The tongue's position alone may prevent the front teeth from fully developing. Allowing the thumb to rest between the teeth has the same effect — and it can also push the front teeth forward. Other causes of an open bite are skeletal or jaw-related problems.
It is harder to cure open bites caused by thumb sucking or bad tongue position than those from other causes.
Open bites that are caused by skeletal factors (patterns of bone growth, etc) are often difficult to resolve. Those caused by dental factors (tongue position, tooth eruption, etc) are generally easier to fix. However, the pressure exerted by the thumb over a long period of time can influence bone growth in the jaw.
There is a dental appliance that can help discourage thumb sucking.
A thin metal “tongue crib” placed behind upper and lower incisors discourages the thumb-sucking habit. It also helps to “re-train” the tongue, keeping it from going between upper and lower teeth. To successfully treat an open bite caused by dental factors, and to prevent its reoccurrence, it is essential to eliminate the unhelpful habits of both the thumb and the tongue.

Not long ago, Jane Fonda gave a British interviewer a clue as to how she manages to look so young at her advanced age. During the 2011 Cannes Film Festival, the septuagenarian actress and fitness guru said to a journalist from the London-based Daily Mail, “See these teeth? They cost $55,000. It was teeth or a new car — and I opted for the teeth.”
We think she made the right choice — though she might have overpaid just a tad. Most people don't have that kind of cash to spend on either a car or new teeth. But luckily, you can get either for a lot less — particularly the teeth!
The truth is, at a reasonable cost, cosmetic dentistry really can make you look a lot younger while giving your self-esteem a tremendous boost. It's an investment in both your emotional and oral health as we will never implement a smile makeover without first making sure we've addressed any underlying dental disease. Best of all, it doesn't have to cost anywhere near what you'd pay for the latest-model Jaguar, the price tag of Fonda's smile notwithstanding. Here is a list of the more common cosmetic dental techniques used to enhance a person's smile:
- Whitening — a peroxide-based bleach is applied directly to the teeth to remove minor staining and discoloration.
- Bonding — an acrylic material is applied to a tooth, colored and shaped to match the person's other teeth. Primarily used for chipped, broken or decayed teeth.
- Enamel Shaping — the removal of very tiny amounts of enamel, the tooth's outer layer, for a more pleasing tooth shape.
- Veneers — a thin shell of custom-designed tooth-colored material, usually porcelain, affixed to the front surface of the teeth.
- Crowns and Bridgework — a technique that covers heavily damaged teeth or replaces missing teeth by capping them, or using capped teeth to support one or more false teeth.
- Dental Implants — a small titanium post is surgically implanted in the jawbone to replace the root-part of a missing tooth. A lifelike crown is attached to the implant above the gum line and is the only part of the whole tooth restoration that is visible in the mouth.
- Gum Contouring — a minor surgical procedure altering the position of the gum tissue to improve the look and regularity of the gum line around the teeth.

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?
