There are several causes linked to juvenile periodontitis, a disease which may afflict as many as ten percent of teens. The main cause is a bacterial infection to which teens may be more susceptible because of hormonal changes. A genetic link through the X chromosome may explain why the disease is more prevalent in girls than in boys. Less-than-adequate oral care and too few dental checkups are other contributing factors.

Fortunately, when detected early, juvenile periodontitis can be successfully treated. When teens get regular x-rays, the disease can be discovered before it has caused significant damage. Once a diagnosis is made, scaling and root planing will probably be recommended. An antibiotic course is sometimes recommended as well.

Because gum disease in young people often exhibits no symptoms until the disease has progressed, early detection, through regular dental checkups and x-rays, is very important. Scrupulous home care is another factor. Encourage your teen to brush carefully and floss regularly, and bring him or her in for scheduled exams to eliminate periodontal disease before it gains a foothold.

Thinking about going the natural route with your toothpaste? Natural products do have their advantages, but consider what it is you really want out of a toothpaste before you decide to switch.

If preventing cavities is important to you, then you want a toothpaste that contains fluoride -- preferably one that's approved by the ADA. Some natural pastes will fill the bill for both these requirements, but others don't.

Being a careful label reader is the best way to make your decision. Most natural pastes are known for what they lack: preservatives, sweeteners, and artificial colors. Unfortunately, they may also lack fluoride.

Look for a paste that contains the recommended fluoride and bears the ADA seal. There are some natural brands that make the grade, and they shouldn't be too difficult to find.

Remember, any toothpaste can clean your teeth, since most contain similar ingredients. However, if you want the cavity protection that fluoride provides to both children adn adults, you'll want a toothpaste that contains adequate amounts of fluoride to do the job.
