Tooth sensitivity can be disheartening: you’re always on your guard with what you eat or drink, and perhaps you’ve even given up on favorite foods or beverages.
The most common cause for this painful sensitivity is dentin exposure caused by receding gums. Dentin contains tiny open structures called tubules that transmit changes in temperature or pressure to the nerves in the pulp, which in turn signal pain to the brain. The enamel that covers the dentin, along with the gum tissues, creates a barrier between the environment and dentin to prevent it from becoming over-stimulated.
Due to such causes as aggressive over-brushing or periodontal (gum) disease, the gum tissues can recede from the teeth. This exposes portions of the dentin not covered by enamel to the effects of hot or cold. The result is an over-stimulation of the dentin when encountering normal environmental conditions.
So, what can be done to relieve painful tooth sensitivity? Here are 3 ways to stop or minimize the symptoms.
Change your brushing habits. As mentioned, brushing too hard and/or too often can contribute to gum recession. The whole purpose of brushing (and flossing) is to remove bacterial plaque that’s built up on tooth surfaces; a gentle action with a soft brush is sufficient. Anything more than two brushings a day is usually too much — you should also avoid brushing just after consuming acidic foods or liquids to give saliva time to neutralize acid and restore minerals to the enamel.
Include fluoride in your dental care. Fluoride has been proven to strengthen enamel. Be sure, then, to use toothpastes and other hygiene products that contain fluoride. With severe sensitivity you may also benefit from a fluoride varnish applied by a dentist to your teeth that not only strengthens enamel but also provides a barrier to exposed dentin.
Seek treatment for dental disease. Tooth sensitivity is often linked to tooth decay or periodontal (gum) disease. Treating dental disease may include plaque removal, gum surgery to restore receded gums, a filling to remove decay or root canal therapy when the decay gets to the tooth pulp. These treatments could all have an effect on reducing or ending your tooth sensitivity.

Your nightly snoring has become a major sleep disturbance for you and other family members. But it may be more than an irritation — it could also be a sign of sleep apnea, a condition that increases your risk for life-threatening illnesses like high blood pressure or heart disease.
Sleep apnea most often occurs when the tongue or other soft tissues block the airway during sleep. The resulting lack of oxygen triggers the brain to wake the body to readjust the airway. This waking may only last a few seconds, but it can occur several times a night. Besides its long-term health effects, this constant waking through the night can result in irritability, drowsiness and brain fog during the day.
One of the best ways to treat sleep apnea is continuous positive airway pressure (CPAP) therapy. This requires an electric pump that supplies constant pressurized air to a face mask worn during sleep to keep the airway open. But although effective, many patients find a CPAP machine clumsy and uncomfortable to wear. That's why you may want to consider an option from your family dentist called oral appliance therapy (OAT).
An OAT device is a custom-made appliance that fits in the mouth like a sports mouthguard or orthodontic retainer. The majority of OAT appliances use tiny metal hinges to move the lower jaw and tongue forward to make the airway larger, thus improving air flow. Another version works by holding the tongue away from the back of the throat, either by holding the tongue forward like a tongue depressor or with a small compartment fitted around the tongue that holds it back with suction.
Before considering an OAT appliance, your dentist may refer you to a sleep specialist to confirm you have sleep apnea through laboratory or home testing. If you do and you meet other criteria, you could benefit from an OAT appliance. There may be other factors to consider, though, so be sure to discuss your options with your dentist or physician to find the right solution for a better night's sleep.

Lasers have transformed our everyday lives, especially in healthcare. These intense beams of light of a single wavelength have revolutionized all manner of diagnostics and treatments, from general surgery to cosmetic therapy.
Dentistry has also been influenced by the laser revolution. Here are just a few of the areas where they’re growing in use and popularity.
Early disease detection. Laser instruments can take advantage of “fluorescence,” the tendency of bacteria to “glow” when exposed to certain wavelengths of light. This is proving more effective in detecting early tooth decay in pits and fissures (very tiny areas in a tooth’s biting surface) than traditional needle-like probing instruments called dental explorers. Newer lasers can now detect the same fluorescent qualities in soft tissues, which may reduce the detection time for oral cancer and make the difference between life and death.
Dental caries treatment. Lasers have become an alternative to the dental drill in treating teeth with dental caries (decay). Although with larger cavities lasers are somewhat slower than the conventional drill, they truly shine when it comes to early enamel caries and small cavities because they can be quite precise in the amount of tooth structure they remove. This feature allows them to be less invasive than a dental drill.
Periodontal treatment. Periodontal (gum) disease is an infection caused mainly by bacterial plaque and calculus (hardened plaque deposits) that have adhered to tooth surfaces. Lasers are emerging as an alternative to conventional periodontal (gum) surgery to treat voids or spaces below the gum line called periodontal pockets that have formed because of gum tissue detachment as supporting bone is lost. With their ability to target and destroy infected tissue without damaging nearby healthy tissue, lasers can achieve similar outcomes as traditional techniques but with less tissue damage and discomfort to patients afterward.
Research and development into laser technology continues to perfect these and other applications that promise to make dental procedures less invasive and more comfortable for patients.
