A lisp is a speech defect in which a person mispronounces letters such as “s”, “z” and “dz”. So what causes a lisp, and what should you do? Keep reading to find out.

Key takeaways:

  • Lisps can be caused by an improper bite or misaligned teeth.
  • Children with a tongue tie can also develop a lisp. Others develop a lisp because they learnt to pronounce words incorrectly. 
  • Treatment mainly depends on what caused the lisp. Your dentist can use surgery, orthodontics or speech therapy to promote correct pronunciation.

Talk to your dentist or orthodontist about a lisp. Early treatment helps ensure the best results.
