TheTypeofMouthrinseyouuseCouldbeDoingMoreThanFreshenBreath

As a regular part of your daily hygiene you may be using a mouthrinse — or “mouthwash” — mainly to keep your mouth feeling fresh and clean. Some mouthrinses, though, do more than give you fresher breath.

While there are countless mouthrinses available, we can place all of them into two broad categories: cosmetic and therapeutic. The first refresh your mouth and breath, usually with a mentholated or minty taste and smell that masks unpleasant odors. How well they work is mainly subjective: if you feel better after using them, they’ve done their job.

Therapeutic rinses have a different role, intended to improve oral health in some way. We can divide these into anti-cariogenic (decay prevention) or anti-bacterial rinses. You can find fluoride-based anti-cariogenic rinses over-the-counter in retail or drug stores, usually containing about .05% sodium fluoride per volume. Numerous studies have shown these rinses highly effective in preventing tooth decay when used with daily brushing and flossing.

Likewise, over-the-counter antibacterial rinses have proven somewhat effective in reducing bacteria that leads to dental disease. Formulated usually with triclosan, sanguinaria extract, zinc or essential oils, they can also help reduce the incidence of gingivitis (inflammation of the gums), but only if used in conjunction with brushing and flossing.

Perhaps, though, the most widely studied and substantiated therapeutic mouthrinse is chlorhexidine, a prescription-only rinse. Chlorhexidine inhibits the formation of bacterial plaque on tooth surfaces, the main trigger for both tooth decay and periodontal (gum) disease. It’s often used as a post-surgery rinse when brushing and flossing may not be possible, but dentists will often prescribe it for patients who have a high propensity for dental disease.

Using a mouthrinse depends on your current oral health and personal preferences. Therapeutically, most people gain some added tooth strength protection from using a fluoride rinse in their daily hygiene. If fresh breath and the way your mouth feels are important to you, you should consider such a rinse that also has a pleasant taste and effect for you. We can further discuss with you whether a different type of rinse, or a prescription-strength formula, might be best for your particular needs.

MargotRobbieKnowsAGreatSmileIsWorthProtecting

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.

“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”

Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.

Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.

A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.

Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.

So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

If you have questions about teeth grinding or orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Teeth Grinding” and “The Importance of Orthodontic Retainers.”

ThingsyouShouldKnowaboutOralCancer

Last year, over 1.5 million people heard the words no one wants to hear: “You have cancer.” While only a small portion of those — about three percent — were diagnosed with oral cancer, their survival rate isn’t as good as with other types of cancers: 58% five years after diagnosis.

Here, then, are some things you should know about this deadly disease.

Oral cancer is an “equal opportunity” disease. People from all walks and stations of life experience oral cancer. The disease has caused the untimely deaths of Ulysses S. Grant, Babe Ruth and George Harrison, one of the original Beatles. However, you don’t have to be prominent or famous to acquire oral cancer: it can strike anyone at any age, especially people 40 years and older.

Oral cancer is difficult to detect early. Oral cancer usually appears as a small, scaly-shaped sore known as a squamous cell carcinoma. Appearing in the lining of the mouth, lips, tongue or back of the throat, the early stages often resemble other benign conditions such as cold or canker sores, so they’re easily overlooked in the early stages. To increase your chances of an early diagnosis, you should see your dentist about any mouth sore that doesn’t heal in two to three weeks; it’s also advisable to undergo a specific oral cancer screening during your regular dental checkups.

Tobacco and heavy alcohol use are strongly linked to oral cancer. Tobacco smokers are five to nine times more likely to develop oral cancer while snuff or chewing tobacco users are roughly four times more likely than non-tobacco users. People who are moderate to heavy drinkers are three to nine times more likely to develop oral cancer than non-drinkers.

You can reduce your risk for oral cancer. Besides quitting tobacco use and moderating your alcohol consumption, there are other things you can do to reduce cancer risk: a nutritious diet rich in fresh fruits and vegetables; limited sun exposure with adequate sunscreen protection and clothing; and safe sexual practices to avoid contracting Human Papilloma Virus (HPV16), strongly linked to oral cancer. And above all, practice effective, daily oral hygiene with regular dental cleanings and checkups.
