Coconut oil may be the latest craze in the foodiesphere, but it could also function to prevent cavities, a new study suggests.

Researchers from the Athlone Institute of Technology in Ireland found that enzyme-treated coconut oil -- similar to what would happen to coconut oil after it's been digested -- was able to stop the growth of cavity-causing bacteria.

The finding, presented at the Society for General Microbiology's autumn conference, could lead to a new approach to dental care products, study researcher Dr. Damien Brady said in a statement.

"Incorporating enzyme-modified coconut oil into dental hygiene products would be an attractive alternative to chemical additives, particularly as it works at relatively low concentrations," Brady said in the statement. "Also, with increasing antibiotic resistance, it is important that we turn our attention to new ways to combat microbial infection."

The researchers conducted their study on untreated coconut oil and the enzyme-treated coconut oil. They put the oils up against Streptococcus bacteria, including the tooth decay-causing Streptococcus mutans strain, and found that the enzyme-treated oil stopped its growth.

If untreated, tooth decay can lead to tooth loss and infection, according to the Mayo Clinic. It's caused when plaque -- which is formed from bacteria, bits of food, saliva and acid from the bacteria -- breaks down tooth enamel, eating away the tooth layer by layer.

  • Your 30s: Heed Your Hormones

    If you're pregnant, you might not feel like dragging yourself to the dentist, but you should do it. Higher levels of estrogen and particularly progesterone can result in puffy, tender gums that are vulnerable to minor infection. Flossing is especially important, experts say, because it helps cut the risk of periodontitis, a more serious gum infection that can endanger more than your teeth: some studies have linked untreated periodontal disease to preterm and low-birth-weight babies.

  • Perfect Your Stroke

    Many adults never learned how to brush and floss properly, says Irwin Smigel, D.D.S., president of the American Society for Dental Aesthetics. Use a soft brush that has rounded nylon bristles and make gentle circular motions at a 45-degree angle to your gum line. If flossing hurts or makes your gums bleed, keep working at it. "The more you floss, the tougher your gums become," explains Paula Jones, D.D.S., immediate past president of the Academy of General Dentistry. <em>Flickr photo by <a href="" target="_hplink">Ken Wilcox.</a></em>

  • Kick Those Butts

    "Smokers get periodontal disease at two to three times the rate of nonsmokers," says Sally Cram, D.D.S., a periodontist in Washington, D.C., and a consumer advisor for the American Dental Association. Smokers also don't heal as well after getting treatment for these gum infections. <em>Flickr photo by <a href="" target="_hplink">tiffa130</a></em>

  • Ditch The Diet Cola

    Even sugar-free soda can destroy your pearly whites, thanks to the high acid content of most carbonated beverages. "Acid weakens enamel and makes it softer," Jones says. A fluoride rinse can help strengthen it. <em>Flickr photo by <a href="" target="_hplink">Steve Parker</a></em>

  • Your 40s: Book Your Appointment

    No matter how busy you are, make time for the dentist because he can spot signs of serious illness that shouldn't be ignored. For example, gum disease can be a sign of uncontrolled diabetes. Plus, oral cancer is more common after 40; your dentist will look for symptoms, such as unusual swelling or sores, as well as painless lesions.

  • Get Off The Daily Grind

    Grinding or clenching your teeth (which can intensify if you're stressed) can cause excessive wear and even cracking and chipping. "A lot of tooth wear starts to show up in the late 30s and 40s," Jones says. "Your dentist can see if you're grinding, because areas of the tooth enamel will be worn smooth." If your teeth show these signs, your dentist can give you a mouth guard. Stress-management techniques can also help you keep from clenching.

  • Consider A Renovation

    Dental work you had done in your teens may need to be replaced. "If you've had lots of fillings or crowns, get them checked, because they do wear out," Cram says. A cracked or chipped filling can create a space for bacteria to collect, causing decay.

  • Beware Of Overbleaching

    "Once you achieve the shade you want, you can touch up once or twice a year," Jones says. "Any more than that can be damaging." While evidence that bleaching erodes enamel is inconclusive, it may increase sensitivity. And, the truth is, there's a limit to how much whitening you can achieve as you get older.

  • Your 50s+: Bone Up

    Bone loss is one of the main reasons people lose teeth, Smigel says. A healthy diet with enough calcium and vitamin D can help you maintain strong bones. And if you have a family history of osteoporosis or periodontal disease, dental checkups are a must. "Dental X-rays can show the progression of osteoporosis," Jones says. If you do lose a tooth, try to get an implant, Smigel advises. "It stabilizes the jaw so the bone doesn't shrink and make your face look older."

  • Wet Your Whistle

    Many medications (including antidepressants and heart or pain meds) can dry out your mouth, which ups the risk of tooth decay. If you have dry mouth, Jones recommends using a fluoride rinse at night, which can help protect the enamel. Drinking lots of water or chewing sugarless gum can also help. <em>Flickr photo by <a href="" target="_hplink">OiMax</a></em>

  • Take Heart

    Studies show that people with periodontal disease may have higher risks of heart attack and stroke, possibly because the infection increases inflammation throughout the body. "I can't say that you're going to have a heart attack if you don't take care of your teeth," Cram says. "But if you have a family history of heart disease or other heart disease risk factors, it's a good idea to pay extra attention to your oral health."
