In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

Do you wake up in the morning still feeling tired? Are you drowsy, irritable or have difficulty concentrating? And is your snoring habit a running joke around your household?
If you mostly answered yes, you may have obstructive sleep apnea (OSA). This condition is more than an irritation—it could also have major health implications if not addressed.
OSA occurs when the airway becomes temporarily blocked during sleep. The tongue (or other mouth structures like tonsils or the uvula) is often the cause as it relaxes and covers the back of the throat. Although you’re asleep, the brain notices the drop in oxygen and initiates arousal to unblock the airway. As this action usually only takes a few seconds, you may not fully awake every time; but because it can occur several times a night, it can rob you of the deep sleep you need for well-being.
If you’re diagnosed with OSA, your doctor may recommend continuous positive airway pressure therapy (CPAP). This treatment uses a pump device to supply continuous pressurized air through a hose connected to a face mask worn during sleep. The elevated pressure helps keep the airway open.
While this approach is quite effective, many people find wearing the equipment uncomfortable or confining, and may choose not to use it. If that describes you, a qualified dentist may be able to provide you with an alternative called oral appliance therapy (OAT).
OAT uses a custom-made plastic oral appliance you wear while you sleep. The most common snaps over the teeth and uses a hinge mechanism to move the lower jaw (and the tongue with it) forward.
OAT is recommended for people with mild to moderate OSA, or those with severe symptoms who can’t tolerate CPAP. If you’d like to see if an OAT appliance could help you, contact us for a complete oral examination. Either treatment can improve your sleep and daily lifestyle, as well as help prevent certain health issues in the future.

Your gums aren’t just for show—they also play an important role in supporting and protecting your teeth. Healthy gums are essential for healthy teeth.
Your gums can take a lot from daily chewing or other environmental factors. Unfortunately, disease or trauma can weaken their resilience. This weakening could lead to gum recession.
Gum recession occurs when the tissues covering a tooth begin to lose their attachment and shrink back (recede). As a result, the tooth appears “longer” as more of it that’s normally below the gum line becomes visible. Not only is gum recession unattractive, it also exposes more of the tooth to disease-causing bacteria.
The most common cause for gum recession is periodontal (gum) disease, an infection arising from the accumulation of a thin bacterial biofilm on the teeth called plaque. Infected gums become inflamed, a normal defensive response to isolate diseased or damaged tissues from the rest of the body. Chronic inflammation, however, weakens affected tissues over time and results in bone loss.
Other factors can also contribute to gum recession. A tooth that didn’t erupt properly and has come in away from the center of its protective bony housing can impede adequate gum coverage. Your gum tissue thickness, which you genetically inherit, can also increase the risk of gum recession. People with thinner gum tissues are more susceptible to recession than with thicker tissues.
You can also damage your gums (ironically) while trying to care for them. Over-aggressive brushing over time may traumatize the gums to the point that they recede. While it’s essential in removing disease-causing dental plaque, brushing only requires a gentle scrubbing action covering all portions of tooth surfaces. The brush bristles and mild abrasives in the toothpaste do most of the work of plaque removal.
To minimize the chances of gum recession, you should practice proper oral hygiene and visit your dentist regularly for professional cleanings and checkups. And you might also consider orthodontics for improperly positioned teeth that could not only improve your smile, but also your gum health.
And by all means see your dentist if you notice any signs of gum infection like swollen, reddened or bleeding gums. The sooner you begin gum disease treatment, the less likely your gums will recede in the future.
