With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.
But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.
The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.
The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.
Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.
So, what should you do if you’re a smoker and wish to consider implants?
First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.
It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.

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.
