What it is:
Pain or discomfort when teeth are exposed to hot, cold, sweet, or acidic foods.

Causes:

  • Grinding (bruxism)

Prevention Tips:

These painful spots can appear from stress, injury, biting the cheek, or certain foods. Most heal on their own, but recurring or long-lasting ulcers should be checked.

Stress or hormonal changes

Acidic or spicy foods

Vitamin deficiencies (especially B12, iron, folate)

Viral infections like herpes simplex

Ill-fitting braces or dentures

Crowding occurs when there’s not enough space in the jaw for teeth to align properly.

Problems it causes:

  • Jaw strain or bite problems
  • Lower self-esteem in children and teens

Causes:

  • Genetics
  • Early loss of baby teeth
  • Habits like thumb-sucking

Treatment options:

  • Braces or clear aligners (Invisalign)
  • Early orthodontic evaluation (ideal by age 7 )

Prevention is always better than cure. Most dental issues can be prevented with good oral hygiene habits, healthy food choices, and regular dental visits. If you’re experiencing any of the symptoms mentioned above, don’t wait — your smile is worth protecting.
