Like the rest of healthcare, antibiotics have transformed dentistry. Advanced oral infections that once eluded successful treatment are routinely stopped with the use of these “wonder drugs.” But their overuse over the years has given rise to dangerous “superbugs” resistant to many antibiotics.
Antibiotics are one of the 20th Century's most significant healthcare achievements. Drugs like penicillin played a major role ending the global threat of tuberculosis, cholera and bacterial meningitis. Over the last few decades, more antibiotics have been developed to defend against an even wider array of bacterial dangers.
But along the way doctors and dentists began prescribing antibiotics for all manner of illnesses including viral infections like colds or flu for which they're less effective. They've also been increasingly used as a preventive measure, including inclusion in animal feed to fight disease.
But our tiny biological nemeses are adaptable. As bacterial strains come in contact with greater amounts of antibiotics, individual bacterium that survive transmit their resistance to subsequent generations. This can produce new strains like Staphylococcus aureus (MRSA) that are resistant to methicillin and other common antibiotics that once contained them.
There's deep concern that these new resistant strains, often recent incarnations of old diseases once thought defeated, will lead to higher rates of sickness and death. Increasing resistance could also make common procedures like those performed by dentists and oral surgeons, much riskier to undertake.
To combat this, pharmaceutical companies are racing to create new drugs to compensate. Recently, they've received an encouraging sign of hope in this battle from an unlikely source: viruses. Researchers in Tel Aviv, Israel have discovered an antagonistic protein to bacteria among a group of viruses called bacteriophages. The protein, injected into a bacterium, commandeers the cell's DNA function to aid virus reproduction, which kills the host.
In the words of one researcher, this makes these particular “enemy of our enemy” viruses our “friend.” Although the discovery is still a long way from practical use in antibiotics, harnessing it in future drug versions could help pack a greater punch against resistant bacteria.
In the meantime, providers and patients alike must practice and advocate for stricter protocols regarding the use of antibiotics. The viability of tomorrow's healthcare is on the line.
The amount of sugar your child consumes has a huge bearing on their tooth decay risk: The more they take in, the higher it is for this destructive disease. That's why you should moderate their intake of the usual suspects: sodas, candies and other sugar-laden foods. But you should also put the brakes on something considered wholesome and nutritious: fruit juices. And that includes all natural juice with no sugar added.
Sugar in any form is a prime food source for decay-causing bacteria. As bacteria consume leftover sugar in the mouth, they produce acid as a byproduct. With an ample source of sugar, they also multiply—and this in turn increases their acid production. Acid at these high levels can soften and erode tooth enamel, which leads to tooth decay and cavities.
Limiting or even excluding sugar-added foods and snacks can help minimize your children's risk for tooth decay. For designated snack times, substitute items like carrot sticks or even popcorn with a dash of spice rather than sweet snacks and candies. If you do allow occasional sweet foods, limit those to mealtimes when saliva, which neutralizes acid, is most active in the mouth.
As you manage sugary items your children may eat or drink, the American Academy of Pediatrics also advises you to moderate their consumption of fruit juices, including all-natural brands with no added sugar. Their recommended limits on daily juice drinking depend on a child's age and overall health:
- Infants (less than one year) or any children with abnormal weight gain: no juice at all;
- Toddlers (ages 1-3): 4 ounces or less per day;
- Younger children (4-6): 6 ounces or less per day; and
- Older children (7-18): 8 ounces (1 cup) or less per day.
As for the rest of your children's daily hydration needs, the most dental-friendly liquid for any of us is plain water. For older school-age children, low- or non-fat milk is also a sound choice.
Preventing tooth decay in your children is a continuous task that requires all of us, parents and dental providers, to do our part. Besides daily hygiene (brushing and flossing) and regular dental visits, keeping sugar at bay—including with juices—is an important part of that effort.
Bad news at your last dental visit: You have a decayed tooth. And not just in the enamel—the decay has invaded the tooth's inner pulp and the resulting infection is threatening the supporting bone structure.
You're thinking that tooth is toast. Then comes the good news: your dentist believes the tooth can be rescued with a root canal treatment.
But then you begin thinking about how often Uncle Sid says he'd rather undergo a colonoscopy than have a root canal. Is the procedure really as painful and uncomfortable as popular culture says it is? What is a root canal really like?
First step: Things go numb. Uncle Sid is wrong: A root canal treatment is painless because your dentist will first make sure the entire area involving the tooth is anesthetized. This does involve injecting the local anesthetic deep within the tissues, but you won't even feel the needle prick thanks to topical anesthesia applied to the surface gums.
Second step: Drilling deep. After applying a protective dam to isolate the infected tooth from its neighbors, your dentist will drill a small access hole through the enamel and dentin to reach the pulp and root canals. If it's one of the larger back teeth, the access hole is usually drilled in the tooth's biting surface; in a front tooth, the hole is usually located on the tongue side.
Third Step: Removing diseased tissue. Using special instruments, your dentist will remove the diseased tissue in the pulp and root canals, essentially stopping the infection and any tooth pain you've been experiencing. The empty pulp chamber and canals are often then disinfected with a special antibacterial solution.
Fourth Step: Protecting the tooth. After some shaping, the pulp chamber and root canals are filled with a special filling to prevent further infection. The access hole is then filled and sealed to complete the procedure. At some point in the future, the tooth typically will need a crown to add support and further protection.
You may have some minor discomfort afterward, but this can usually be managed with a mild pain reliever like ibuprofen or acetaminophen. After a week or so, you'll be good as new—and so will your tooth.
