Mouth ulcers, or canker sores, can appear on the gums, roof of the mouth, cheeks and tongue. According to the National Health Service (NHS), you may develop a mouth, cheek or tongue ulcer from biting the inside of your mouth. Genetics, stress, broken teeth, spicy and acidic foods or a burnt tongue may lead to mouth ulcers. Make sure you're getting enough vitamin B12, zinc and iron in your diet because a tongue ulcer may develop when you lack these nutrients. This type of sore on your tongue typically goes away on its own within two weeks. You may want to rinse your mouth with a mouthwash for ulcers to soothe the sore and reduce irritation.
People often wonder ‘Are ulcers contagious?’ – but you’ll be relieved to know they’re not. However, it’s worth noting that recurrent mouth ulcers are thought to be hereditary as up to 40% of people who experience them report it runs in their family, as noted by NI Direct. So, if you get this type of sore regularly, your children are likely to get them too. Limit the acidic or rough-textured foods that you or your child eats – and note, that mouth ulcers occur more often in women. If the problem is recurring, consult your doctor about the medications you take or the food you eat that may lead to frequent mouth ulcers.
