What is the reason for mouth ulcers, and how can they be prevented or treated? - #14760
I’ve been getting painful mouth ulcers for the past few weeks, and I don’t know why they keep occurring. I’ve tried over-the-counter gels, but they don’t seem to fully help. What exactly causes mouth ulcers, and why do some people get them more frequently than others? I know stress, diet, and minor injuries can lead to them—are there other common triggers, like certain foods, medications, or hormonal changes? I also want to know how to prevent mouth ulcers from recurring. Are there lifestyle changes, such as avoiding acidic foods or improving oral hygiene, that can help reduce the frequency of these painful sores? What natural remedies or Ayurvedic treatments can promote healing and prevent new ulcers from forming? If anyone has had frequent mouth ulcers, what worked best for you in terms of prevention and treatment? Did changing your diet or using specific remedies help manage the pain and reduce their occurrence?

Doctors’ responses
Mouth ulcers, also known as canker sores, are often triggered by factors such as stress, hormonal changes, a weak immune system, vitamin deficiencies (especially B12, folate, and iron), or food sensitivities. Certain acidic or spicy foods, as well as mechanical injury to the mouth from braces or biting, can also provoke them. To prevent recurrent ulcers, maintaining good oral hygiene, avoiding irritating foods, and managing stress are helpful. Ayurvedic remedies like turmeric, aloe vera, and triphala mouth rinses can aid in healing and reducing inflammation. Additionally, strengthening the digestive fire (Agni) with warm water, a balanced diet, and herbs like ashwagandha may support overall oral health and reduce recurrence.
Mouth ulcers, or aphthous ulcers, can really be a nuisance. You’re right on track with stress, diet, and minor injuries being some triggers. They often occur because of imbalances in your body, reflecting in Ayurveda as dosha imbalances, particularly Pitta. When Pitta is high, it can cause inflammation, showing up as these painful sores. So let’s break it down a bit.
Well, apart from the obvious ones like stress and injuries, certain foods can definitely worsen them. Spicy, salty, or very acidic foods, citrus fruits and even chocolate can irritate your oral tissues. Hormonal changes or nutritional deficiencies especially B12, folate, or iron, also contribute. Even certain medications might be sneaky culprits.
To prevent these ulcers, maintaining balance in your body is key. Ayurveda emphasizes good oral hygiene too, so consider using a soft-bristled toothbrush and a tongue scraper. Avoid any harsh mouthwashes that contain alcohol. Stress management is biggie — yoga, meditation, and pranayama can help calm your mind and body.
Consider dietary choices too–– steer clear of those trigger foods I mentioned. You might benefit from eating more cooling foods like cucumbers, melons or coconut. Shifting towards a Pitta-pacifying diet can help (things that are sweet, bitter, and astringent)
For treatment, there are some excellent Ayurvedic home remedies–try rinsing your mouth with a decoction of Triphala or applying a paste of turmeric and honey directly on the ulcer. Drinking aloe vera juice or chewing licorice root can help soothe and promote healing as well.
Ultimately, it’s about listening to your body, assessing what works for you and the lifestyle you lead. Everyone might respond a bit differently. Don’t overlook seeing a healthcare prof if they become too frequent or severe though!
