Mouth Ulcers

Most mouth ulcers heal within a week or two, but recurring or unusually large ulcers are worth having checked.

01 — Why it matters
Most ulcers heal on their own.

Mouth ulcers are very common and usually clear up within a couple of weeks. They often appear after a minor knock, a bite, or during times of stress or hormonal change.

However, ulcers that keep coming back, last for several weeks, or appear alongside other symptoms should be checked by a dentist. In rare cases, persistent ulcers can be linked to something that needs further investigation.

02 — Symptoms

Obvious. And often painful.

The signs vary, but most people notice one or more of these:

  1. 01A painful sore on the cheek, tongue or gum
  2. 02A white or yellow centre with a red border
  3. 03Discomfort eating or brushing near the area
  4. 04Ulcers that recur in the same spot
03 — Causes

Where it comes from.

The most common culprits:

Accidental biting or injury
A sharp edge or minor trauma inside the mouth.
Stress or hormonal changes
Common triggers for outbreaks.
Certain foods
Particularly acidic or spicy ones.
Vitamin or mineral deficiencies
Iron, B12 or folate shortages in some cases.
04 — When to see a dentist

Don't wait it out.

Speak to your our practice dentist if you're experiencing any of the following — book an appointment as soon as you can:

  • An ulcer lasting more than 2-3 weeks
  • Ulcers that keep recurring
  • Unusually large or painful ulcers
  • Ulcers alongside other unexplained symptoms
05 — What to do about the pain

In discomfort right now?

Salt water rinses and avoiding spicy or acidic food can ease discomfort, but ulcers lasting beyond a couple of weeks should be checked.

06 — What's next

A plan, not a quick fix.

Most ulcers need no treatment beyond time, but persistent or unusual ulcers are worth a proper look to rule out other causes.
