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.

It’s hard to imagine, but little more than a century ago today’s “minor” bacterial and viral infections were often deadly. This changed with the advent of antibiotics, drugs which kill disease-causing microbes. Decades after the development of penicillin and similar antibiotics, we routinely rely on them for treating infection. They’re quite prominent in dental care in treating advanced forms of periodontal (gum) disease or reducing bacteria that cause tooth decay.
But the age of antibiotics may be in danger: their overuse in medicine and the food industry has led to the rise of resistant microbial strains — “superbugs” — that no longer respond to first line antibiotics or, in some cases, to second or third line drugs. The U.S. Center for Disease Control (CDC) estimates more than two million people annually will contract one of these superbugs of which more than 20,000 will die. If current practices continue, the growth of resistant strains (as well as allergic reactions among users of antibiotics) will increase. The answer is a more modified use of antibiotics.
For healthcare providers, this means adopting new protocols in which we attempt to prescribe antibiotics that specifically target an identified microbe (which we’ve determined through more rigorous diagnostic testing), and in limited amounts. We must also rein in the practice of antibiotic use in the food industry, routinely administered to livestock to prevent disease or to enhance growth. Many countries, including the U.S., are now moving toward a more limited practice in which only animals that are demonstrably sick receive antibiotics. This will limit their release into the greater environment, which is a contributing factor to growing microbial resistance.
Patients also play a role in the better use of antibiotics. We must first change the perception that antibiotics are a “cure-all” — the answer to every illness. It’s also important for patients who’ve been prescribed antibiotics to complete the course of treatment, even if after a day or two they feel better; stopping antibiotic treatment prematurely increases the chances targeted microbes develop a resistance to that particular drug.
Altering our perception and use of antibiotics will require a tremendous effort for all of society. But making these changes will help ensure antibiotics continue to serve humanity as an important health benefit well into the future.
Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.
