Your Toothpaste May be Giving you Canker Sores (and bad breath)
Unfortunately, the public ends up creating their own "canker sore" problem, by using commercial toothpastes, which contain an ingredient that has been proven to be linked to canker sores. It's called Sodium Lauryl Sulfate (SLS), and is placed into toothpaste (and some mouthwashes) in order to create foaming. (Sodium Lauryl Sulfate is also the main ingredient in your shampoo).The harshness of this chemical has been proven to create microscopic damage to the oral tissue which lines the inside of your mouth, which then leads to Canker Sores. The Science of Canker Sores: For discussions sake, several terms are interchangeable. Canker Sores are also known as: Mouth Ulcers, Aphthous Ulcers, Recurrent Aphthous Stomatitis, or Oral ulcers. Some people (and doctors) confuse canker sores with "cold sores" (fever blisters). We know both are painful, annoying, and recurring. Here are the major differences:
|Canker Sores -only occur inside the mouth -not contagious -not viral (not caused by a virus -Caused by damage to oral tissue, often by Sodium Lauryl Sulfate, a common foaming agent ingredient in almost all toothpaste.||Cold Sores - Mostly on outside of mouth - sometimes on the inside of the mouth, but only on "hard" surfaces (palate). -Contagious -not viral -The first sign is appearance of small blisters (vesicles)|
What Causes Canker Sores ( Mouth Ulcers)? The latest research shows that certain chemical compounds trigger the production of canker sores. Among those items is something that may shock unsuspecting people. It's SOAP. Yes, but it's soap, inside your mouth. For many years the major pharmaceutical companies have used Soap (chemically known as Sodium Lauryl Sulfate) in order to create a foaming agent when one brushes their teeth. The reason? The foam does not provide any benefits to the toothpaste, but does "fool" the user (YOU) into thinking that a foaming action is related to a "cleansing" action. After speaking to many of these pharmaceutical companies, the following excuse is used: "We use Sodium Lauryl Sulfate as a surfactant, in order to blend all of our ingredients together and make them work more effectively." (A surfactant is a chemical agent, which allows other chemical molecules to get closer to each other. However, there are many surfactants out there that are not soapy or do not cause allergic reactions, resulting in canker sore production." One of the most exciting advances has been the establishment of the link between canker sores and an ingredient common to almost all toothpastes. The additive SLS or sodium lauryl sulfate may be a culprit in canker sore formation. SLS ( sodium lauryl sulfate ) acts just like a detergent. It is used in the laboratory as a membrane destabilizer and solubilizer of proteins and lipids. SLS is used in toothpaste to emulsify (mix) oil and water based ingredients together. In your toothpaste it creates the foam you get when brushing. Since it is classified as a soap, you will easily understand, why this ingredient can cause drying inside the mouth for many individuals. The dryness is one of several factors that will lead to bad breath. To avoid this, you must stop using toothpaste that contains SLS. Also, to avoid dryness and bad breath, I recommend toothpaste that oxidizes the mouth, and mouthwash that does not contain alcohol (a drying agent). The thought is that SLS may, in susceptible individuals, cause microscopic trauma or membrane disruption to the skin cells in the mouth. This along with trauma or actions of the immune system may lead to canker sore formation. Recent studies have shown a link between the use of toothpastes containing SLS and the occurrence of RAS (canker sores). The following is a synopsis of 3 European Scientific Studies: In a study at the University of Oslo in Oslo, Norway, Drs. Barvoll and Brokstad revealed a 60-70% reduction in the number of canker sores in patients who used SLS free toothpaste during the 3 month test period. Additional studies have since shown equally promising results. In the clinical studies, patients using SLS toothpaste displayed a greater amount of desquamation (loss of a layer of skin lining the inside of the mouth). This has led to the theory that SLS may contribute to RAS (canker sores) by causing injury to the oral epithelial cells (skin cells lining the inside of the mouth). SLS, by denaturing protective mucus proteins, may also disrupt the protective layer of mucus which lines the inside of the mouth (a denatured protein is a protein which has lost its three dimensional shape thereby becoming nonfunctional and useless). The denaturing of mucus proteins makes the cells lining the mouth more susceptible to injury and canker sore formation. References 1.

Additionally, many of the visitors to this website have also found canker sore relief by using an SLS free toothpaste. Research is being conducted to determine what makes a person susceptible to canker sores in the first place as well as what actions and mechanisms trigger canker sore outbreaks. Among those things that may trigger an attack or make a person more susceptible are: A. SLS found in Toothpaste and some mouthwashes B. Allergies to Food Products and Certain Preservatives C. Trauma from Brushing your Teeth too vigorously D. Lip Biting E. Stress F. Trauma from Eating Hard, Rough Foods (Potato Chips, Pretzels) G. Deficiencies in Vitamin B12, iron, and folic acid. Current theories on the causes of canker sores have focused on the immune system. This research suggests that canker sores may be caused by the body's own immune system attacking the cells lining the inside of the mouth. The first canker sores usually occur between the ages of 10 and 20. During life, episodes usually, but not always, become less frequent and less severe. Interestingly, women often report increased susceptibility to canker sore formation during certain times of their menstrual cycle. Some women report complete relief from canker sores during pregnancy. Interestingly, canker sores ( mouth ulcers ) affect people to varying degrees of severity. Some people may get an occasional outbreak of canker sores once or twice a year while others may suffer near continuous overlapping episodes of canker sores ( mouth ulcers ). On the Subject of Preventing Canker Sores (Mouth Ulcers) The most important piece of advice we can give you is to stay away from toothpaste which contains Sodium Lauryl Sulfate. Examine your toothpaste's ingredient section and see if it contains SLS. You will be saving yourself a lot of pain in the long run. I recommend Therabreath, created in the California Breath Clinics, a clinic that has treated over 13,000 people with bad breath. It doesn't contain SLS (you'll notice that it doesn't create as much bubbles) but does a better job of cleaning your mouth. Avoiding SLS is avoiding canker sores, which no one wants to have. Secondly, trauma to the inside of the mouth may trigger the production of canker sores. This trauma includes overzealous tooth brushing, biting your cheek or tongue, and scraping the inside of your mouth with hard or sharp foods (like hard pretzels). Cut down on eating foods like potato chips, hard pretzels, cut apples, and hard candies which might nick, abrade, or otherwise traumatize the oral tissue. As far as overzealous brushing, most people can not consciously stop brushing so hard, because tooth brushing is such an ingrained habit. Find a soft nylon toothbrush and brush your teeth gently. One is available here. We know that many bite the insides of their cheeks while sleeping or out of nervousness and stress. We suggest that a mouth guard be worn during sleep. This is often very effective at preventing further oral trauma. Contact your dentist for more information. Reactions to certain food products may be responsible for many cases of canker sores. Among the foods that may cause canker sores in certain people are: nuts, peanut butter, sea food, wheat products, chocolate, and milk. Treatment of Canker Sores (Mouth Ulcers) Usually canker sores clear within 7-14 days without treatment. During this time, however, the canker sores can be painful especially when people eat or drink. Treatment helps ease the pain and may help reduce the amount of time it takes for the ulcers to go away. Other Viable Treatments: 1. Anti-Microbial Mouthwashes Surprisingly the use of anti-microbial mouthwashes has provided effective relief for many. Canker Sores are not caused by a bacteria or virus so the mechanisms by which these anti-microbial mouthwashes work remains unclear. Commonly used are anti-microbial Oxygenating mouthwashes. 2. Analgesic (Pain Relieving) and Protective Ointments and Gels: Your local drug stores stocks some pain relieving medications, including Zilactin or Oragel. After application, they create a protective cover over the sensitive areas. 3. Corticosteroid Rinses and Gels: These are prescription medications that must be authorized by your dentist or physician and should only be used for severe or painful cases. The application of these types of gels and rinses may be painful at first. The most common is a topical steroid gel (non-alcoholic) of lidex applied very gently to the ulcer 2-4 times per day. Systemic Conditions Associated with Canker Sores (Mouth Ulcers) In a very small number of cases, canker sores may be indicative of a bodily (systemic) disorder. A medical condition known as Behcet's Disease, for instance, has amongst its symptoms: canker sores, genital lesions, eye lesions, and dermal afflictions. Those infected with HIV may also develop "canker sore like" ulcers. Some digestive conditions display canker sores as part of their disorder. These include: Crohn's Disease, Celiac Disease, Ulcerative Colitis, and gluten hypersensitivity (wheat allergy). Consult your physician if any of the above sound like they may be part of your "canker sore" problem.
