What Is a Mouth Sore or Canker Sore and What Are the Causes?

People often use the terms "canker sores" and "cold sores" interchangeably. While both are very painful, a canker mouth sore is found on the inside of the mouth and is not contagious; cold sores are located on the inside or outside of the mouth and are contagious.

Canker Sores:

These sores are found inside the cheeks, on your tongue or the bottom of your mouth, and sometimes on your gums. They range from the size of a tiny pinhead to a penny. The sores are grayish-white in the center and circled with a red inflammation. Since it's an open mouth sore, it hurts when touched by anything, including saliva. They can burn and itch, too.

Canker sores might be called the "stress sores," because they are caused by different types of stress:

• Emotional stress;
• Physical stress, such as biting your tongue, burning your mouth, or an abrasion from braces or loose dentures; or
• Chemical stress producing changes in your body, perhaps resulting from an illness or change in eating habits (such as medications, or too much of acidic foods such as tomatoes, grapefruit, or lemons).

About one in five people get them. Women in the 20-to-50 year age group get them more often. Once you get them, you're likely to experience them again. However, they usually go away after seven to ten days, although some can be longer-lasting.

An antimicrobial mouth rinse may lessen the irritation. Temporary relief can be provided by over-the-counter topical anesthetics. Pain relief varies with different products. Some medications provide a protective film that physically blocks contact with food and saliva, lessening irritation.

Good oral hygiene and a healthy diet are preventive measures for reducing the frequency of outbreaks.

Cold Sores

Also known as fever blisters, cold sores are caused by the virus herpes simplex. These are painful blisters that usually break out around the lips and sometimes under the nose or chin and normally heal within one week. They are very contagious. The virus stays in the body, causing recurrent lesions prompted from a fever, sunburn, skin abrasions, or stress.

They can be treated by your dentist with the same topical anesthetics to relieve pain and irritation as for canker sores. Prescription antiviral drugs can be effective in reducing viral infections that cause flare-ups.

Additionally, there are new topical medications (ointments) now available that shorten the duration of a breakout, when applied immediately after the cold mouth sore is noticed. All antiviral medications work best in the prodromal or early stage of the lesion. If the wound is open and sore, these medications are of little use as the healing time is still the same.

Be sure to consult with your dentist when any mouth sores do not heal.

Family Dentistry: Dental Hygiene and Your Dental Care Team

The new dentistry brings together a unique complement of skills, knowledge, and capabilities with one primary focus: ensuring your dental health. Working as a team, your dentist and the dental team he or she has assembled wants to recruit you to join them in making sure this focus is maintained. The dental team has two major parts that you may hear referenced during your visits: the "back" and the "front." These terms refer to two very specific functions of your dental team. The front office handles all the administration, scheduling, and financial details, and the back office provides the treatment.

Your front office team makes sure you know about scheduling opportunities, handles finances, and keeps the administrative details under control to provide you efficient services and support. The back office team is thus free to do what they do best: provide the best care and service for you. You'll find the dentist, dental hygienist, and dental assistant ready to assist you during your appointments.

The key component for success of any team is each member's commitment to do their part. As a consumer and team member, your commitment involves three things:

1. Maintaining your commitment to your dental health through regular dental hygiene appointments and the daily practice of flossing and brushing.
2. Asking questions and getting the essential information you need about your teeth and gums or to understand any treatment plans.
3. Staying open to options and opportunities that the new dentistry offers you by thinking about the information and feedback that your dentist provides you about the status of your dental health.

You can maximize the benefits of the skills and expertise of your dental team by deciding for yourself what kind of relationship you want with your dentist and the dental team and how they can help you achieve a positive outcome for your dental future.

Bad breath, or halitosis, is a signal that something is not right inside your mouth. It may be as simple as the need to pay more attention to your daily dental hygiene, or it may indicate tooth decay, gum disease, or another medical problem. Whichever it is, bad breath is a red flag: take another look at your mouth!

Bad breath is a social problem; if you have bad breath, you may notice that people actually back away as you talk to them. Mouth odors are embarrassing, and they tell other people that you aren't taking care of yourself. Sometimes people are not aware that their breath smells bad; be alert to how other people react when they're close to you, and be grateful if a friend or family member lets you know about the problem.

Commercial products claim they will make your breath fresher, but the only way to make sure your breath permanently fresh is to practice good oral hygiene. In fact, too many breath mints and hard candies with sugar will lead to tooth decay. If you are constantly using breath mints, breath sprays, or mouth rinses in an effort to cover up your bad breath, realize that you may have a dental or medical problem that needs addressing.

There are a number of reasons you may experience a bad taste in your mouth, and even be able to smell your own breath. Food may be lodged between your teeth if you are not brushing at least twice daily and flossing regularly. Food particles can be very tiny and can wedge themselves between teeth and below the gum line; brushing after meals is important and flossing is imperative to get at the particles that the brush can't reach. Brush your tongue or use a tongue scraper. As odd as it will feel at first, bacteria collects on the tongue and can contribute to bad breath. If you wear removable dentures, take them out at night and clean them thoroughly before you wear them again.

If you neglect your daily dental hygiene over time, bad breath can become a symptom of more serious dental problems. Teeth that are not cleaned properly become a place for bacteria to reside as food particles stay in your mouth and decay. Bacteria attack your teeth and gums and cause cavities and gum disease. If this is happening, gum disease will cause an unpleasant odor.

Perhaps you believe that you are brushing and flossing on a regular basis, but are still experiencing bad breath. If you have teeth that are crooked or crowded, it may be hard for you to clean between them. If you wear dentures that are not fit properly, they may be trapping food or irritating your mouth. Or perhaps your bad breath is caused by another medical problem: drainage from your sinuses, gastrointestinal problems, kidney or liver problems, or other medical conditions.

Here's what you can do to "investigate" on your own. Write down what you're eating and notice whether your breath smells bad because of certain foods. Garlic and onions actually cause odor, but the odor is coming from your lungs as you breathe, not from your mouth itself. The odor from these foods is temporary, and will be gone once the food is out of your bloodstream.

Are you dieting? Hunger can contribute to bad breath, because of the chemical changes as your body turns fat and protein into the energy it needs. Taking prescription or over-the-counter medications? Add these to the record of what you're eating to see whether there's a relationship between your medications and your bad breath. And don't forget to tell your dentist if there's been a change in your overall health since your last visit.

Suffering from dry mouth? Saliva provides constant rinsing in our mouths and washes away food particles. Your dentist may recommend more liquids, sugarless candy to stimulate natural saliva, and perhaps some of the commercial products that are available to combat dry mouth.

If bad breath continues after you have done your best job of regular brushing and flossing, start with your dentist. He or she can tell you whether the odor is caused by an oral problem; if it is not, then your dentist will suggest you see your doctor for a physical check-up.

Regular dental check-ups will help keep your mouth healthy and working well. Your dentist can spot problems before they cause trouble, including problems that cause bad breath.
