Scalloped Tongue

A scalloped tongue, also called crenated tongue, is a condition where the edges of the tongue appear wavy or ridged, resembling teeth imprints. It is often a sign of an underlying condition rather than a disease itself.

Causes of Scalloped Tongue

1. Tongue Enlargement (Macroglossia)

The tongue presses against the teeth due to its size.

2. Bruxism (Teeth Grinding)

Repeated pressure from clenching or grinding the teeth at night.

3. Sleep Apnea

Poor airflow during sleep causes tongue enlargement.

4. Vitamin or Mineral Deficiency

Low levels of iron, vitamin B12, or folate can contribute.

5. Dehydration

Leads to swelling and enlargement of the tongue.

6. Hypothyroidism

Reduced thyroid function can cause tissue swelling, including the tongue.

7. Allergic Reactions

Swelling due to food or environmental allergens.

8. Mouth Breathing

Can lead to tongue dryness and enlargement.

9. Temporomandibular Joint (TMJ) Disorder

Jaw misalignment or tension impacts the tongue's position.

10. Chronic Stress or Anxiety

May result in habitual clenching or pressing of the tongue against teeth.
