Once in our lifetime, almost all of us have observed open and shallow sores in our mouth, and we consider it normal, but then we take some acidic or citrus drink. Taking that drink is so pathetic that you will start hating your favorite beverage.
Also termed aphthous ulcers, canker sores are whitish to reddish small shallow lesions formed on the soft tissue of the oral cavity or at your gums. The most common side of canker sores is the cheeks, but it is sometimes also formed in other areas. They are not contagious like cold sores. Canker sores can be so painful that your eating routine will be disturbed.
Most of the time, canker sores are healed over time. You can take over a counter pain reliever during this time so your pain doesn’t exaggerate during eating or speaking.
In addition to nutritional care and taking over-the-counter medicine, be careful when you brush your teeth. Brushing with toothpaste with harsh ingredients will prolong the healing process and exaggerate your pain.
Most the Toothpaste contains Sodium Lauryl Sulfate, a foaming agent used in soaps and detergents.
While brushing the SLS-based toothpaste, you may feel clean because of the foaming.
But SLS is declared a high hazard for causing irritation and organ toxicity by EWGs. If you develop canker sores, make sure that you use SLS-free toothpaste. If you are someone with canker sores, we have prepared a list of the best toothpaste for canker sores for you.
