Mouth ulcers are common and usually harmless, but they can be a real pain—literally! If you’ve ever dealt with a sore spot inside your mouth, you know how uncomfortable they can be. While most ulcers clear up on their own within a week or two, there are times when seeing a dentist is essential. So, how do you know when to make that appointment?
What Exactly Are Mouth Ulcers?
Mouth ulcers, also known as canker sores, are small painful sores that appear inside the mouth, often on the lips, cheeks, gums, or tongue. They can be caused by various factors, such as stress, minor mouth injuries, acidic foods, or even certain medications.

When Is It Time to See a Dentist?
While most mouth ulcers heal without treatment, there are situations where professional help is needed. If you experience any of the following, it’s time to see a dentist:
- Ulcer Lasts More Than Two Weeks: Most ulcers should heal within 7-10 days. If your ulcer sticks around for more than two weeks, it could be a sign of a more serious issue.
- Severe Pain: If the pain is intense, making it difficult to eat or talk, or if over-the-counter remedies aren’t providing relief, it’s best to consult a dentist.
- Recurring Ulcers: Frequent mouth ulcers could point to underlying health issues like nutritional deficiencies, gastrointestinal problems, or an autoimmune condition.
- Larger Than Usual: If the ulcer is unusually large or shows no signs of healing, it could indicate something more serious, such as an infection or oral cancer.
- Associated Symptoms: Ulcers accompanied by fever, fatigue, or swollen lymph nodes may require further investigation to rule out a systemic condition.
Why Should You See a Dentist?

A dentist can provide a thorough examination to determine the cause of the ulcer and recommend appropriate treatment. Whether it’s a prescription medication, lifestyle changes, or further testing, getting professional care can speed healing and ensure that no underlying condition needs attention.
Home Remedies: What You Can Do in the Meantime
Before visiting a dentist, you can try some of these home remedies to soothe your symptoms:
- Rinse with warm Salt Water: A warm saltwater rinse can help clean the ulcer and speed up healing.
- Apply Milk of Magnesia: Dab a bit of milk of magnesia on the ulcer to neutralize acid and reduce irritation.
- Avoid Irritating Foods: Spicy, salty, or acidic foods can worsen the pain, so it’s best to steer clear while healing.
Conclusion: Don't Ignore the Signs
While mouth ulcers are common, don’t hesitate to see a dentist if your symptoms persist or worsen. Ignoring the signs could lead to unnecessary discomfort or complications. Your mouth is a key indicator of your overall health, so listen to what it’s trying to tell you!
