One of the biggest concerns we hear from parents is about their child's thumb sucking habit. Our advice: if they're under age 4, there's no need for concern — yet. If they're older, though, you should be concerned about the possible effect on their bite.
Thumb sucking is a universal habit among infants and toddlers and is related to their swallowing pattern during feeding. As they swallow, their tongue thrusts forward to create a seal with the lips around the breast or a bottle nipple. Many pediatricians believe thumb sucking replicates nursing and so has a comforting effect on infants.
Around age 4, though, this swallowing pattern begins to change to accommodate solid food. The tongue now begins to rest at the back of the top front teeth during swallowing (try swallowing now and you'll see). For most children, their thumb sucking habit also fades during this time and eventually stops.
But for whatever reason, some children don't stop. As the habit persists, the tongue continues to thrust forward rather than toward the back of the top front teeth. Over time this can place undue pressure on both upper and lower front teeth and contribute to the development of an open bite, a slight gap between the upper and lower teeth when the jaws are shut.
While late childhood thumb sucking isn't the only cause for an open bite (abnormal bone growth in one jaw is another), the habit is still a prominent factor. That's why it's important that you start encouraging your child to stop thumb sucking around age 3 and no later than 4. This is best accomplished with positive reinforcement like rewards or praise.
If they've continued the habit a few years after they should have stopped, we may also need to check to see if their swallowing mechanism has become stunted. If so, we may need to use certain exercises to retrain their tongue to take the proper position during swallowing.
While you shouldn't panic, it's important to take action to stop thumb sucking before it becomes a long-term problem. A positive, proactive approach will help avoid costly orthodontic problems later in their lives.

You would love to replace your missing teeth with dental implants. And for good reason — they're the best way to restore life-like, functional teeth. But there's one problem — implants and fixed bridgework (the next, best option) are financially out of your reach.
There's another viable option, though, that might fit your budget — removable partial dentures (RPDs). Similar to full dentures, RPDs replace only the missing teeth in a dental arch. And they're much less expensive than implants or bridgework.
RPDs are custom made to fit an individual patient and their particular missing teeth locations. Their frameworks are usually made of vitallium, a strong but lightweight metal alloy. With vitallium, the frame can be made thin enough not to be noticeable but still conduct sensation.
A pink resin or plastic that mimics gum tissue covers the frame, to which we attach prosthetic (false) teeth made of porcelain, glass-filled resin or plastic to precisely match the missing teeth locations. The RPD is held in place with small metal clasps that fit around remaining natural teeth.
RPDs are designed to minimize movement and avoid undue pressure on the gum ridges, which could accelerate underlying bone loss. In certain situations, though, the location of some missing teeth could complicate matters. If you're missing a tooth in the back where the appliance coverage ends, the RPD may not be as stable.
The solution, ironically, could be a dental implant placed strategically at the end of the RPD, where it connects securely with the appliance. You would only need one or two implants, which won't dramatically increase costs.
One thing to remember with an RPD: they tend to accumulate bacterial plaque, the trigger for both tooth decay and periodontal (gum) disease. That's why it's important to practice daily effective hygiene by cleaning the RPD and your remaining teeth and gums, as well as taking the RPD out at night.
A well-maintained RPD could last for many years. With this appliance you can still have functional teeth and a winning smile, even without implants.

Thanks to treatments like chemotherapy and radiation, your chances of surviving cancer are greater than ever. These treatments, however, often produce unwelcome side effects. Treating throat or oral cancer, for example, could damage your mouth's salivary glands or bone.
Saliva is essential to oral health, providing antibodies to curb the growth of disease-causing bacteria and neutralizing acid, which can erode enamel. But salivary glands damaged during cancer treatment may not be able to produce enough saliva. The resulting “dry mouth” creates an environment conducive to bacterial growth and elevated acid levels.
You can help reduce the effects of dry mouth during your treatment (and after, if the damage is permanent) by drinking more water or by using substances that stimulate saliva. Cutting back on acidic foods and beverages will also help lower your mouth's acidity. And be sure to keep up daily oral hygiene and regular dental visits.
The more ominous threat to oral health during cancer treatment, though, is osteoradionecrosis. This occurs when radiation targets specific areas of bone. The bone can lose blood supply and living cellular tissue, which inhibit its ability to heal or replenish itself. If this occurs in the jawbone of teeth that may be lost, the bone tissue could be adversely affected during healing.
Depending on your treatment needs, your risk for osteoradionecrosis might be unavoidable if teeth are to be lost. It's important we discuss that risk because it could impact future dental treatment. In the worst case, before cancer treatment, we may not be able to save affected teeth and your restorative options might be limited.
If your risk of osteoradionecrosis is minimal, though, we may be able to restore any resulting damaged or missing teeth with a wide range of options like dental implants or crowns before or after your cancer treatment.
As with other aspects of health, taking care of your teeth and gums while undergoing cancer treatment can be challenging; some problems may be unavoidable. But with a proper dental treatment plan during and after chemotherapy and radiation, we can minimize those problems and help to eventually restore your smile.
