Canker sores are small, painful ulcers that develop inside the mouth, often appearing on the gums, inner cheeks, or tongue. These open sores can make eating and drinking uncomfortable, as certain foods and beverages can irritate them further. Understanding which drinks are gentle and which to avoid can significantly improve comfort and promote healing.
Soothing Beverages
Water, whether lukewarm or cool, is a primary choice for maintaining hydration without causing irritation. Staying well-hydrated supports the body’s natural healing processes. Gently sipping water throughout the day helps keep the mouth moist and can rinse away food particles that might otherwise aggravate the sore.
Lukewarm herbal teas like chamomile and ginger can offer soothing properties. Chamomile contains compounds that may help reduce inflammation, while ginger possesses natural anti-inflammatory qualities that could contribute to comfort.
Diluted fruit juices, such as apple, pear, or grape juice, can be consumed cautiously. Diluting these juices with water reduces their acidity and sugar concentration, making them less likely to irritate the sore. This allows for flavor without the harshness of undiluted, acidic options.
Milk or non-dairy alternatives like almond or oat milk can provide a protective coating over the sore. Their smooth texture and neutral pH can make them easier to swallow. Smooth, non-acidic smoothies made with ingredients like banana, avocado, or spinach blended with water or milk are also good options.
Beverages to Avoid
Highly acidic beverages are best avoided when experiencing canker sores, as they can cause irritation and delay healing. This category includes citrus juices such as orange, lemon, and grapefruit, along with tomato juice. The high acid content in these drinks can sting the open sore, exacerbating pain.
Hot beverages, including coffee, teas, and hot chocolate, can increase pain and inflammation around the sore. The elevated temperature can cause discomfort to the sensitive tissue. Allowing hot drinks to cool significantly before consumption can help, though it is often safer to choose lukewarm or cool alternatives.
Carbonated drinks, such as sodas and sparkling water, should be avoided. The fizziness, combined with the high acidity present in many soft drinks, can irritate the canker sore. This combination of carbonation and acidity can lead to a burning sensation upon contact with the ulcer.
Alcoholic beverages can irritate the mucous membranes in the mouth and cause drying, which can worsen the discomfort of a canker sore. This dehydration can interfere with the healing process. Drinks with high caffeine content can also contribute to dehydration, which is counterproductive when the body is trying to heal.
