Biting the tongue, whether in children or adults, is a common behavior that can be noticed daily. Sometimes, it is a normal response, but other times it may indicate an underlying issue that requires attention. Whether your child bites their tongue while playing, an infant frequently sticks out their tongue, or adults bite their tongue during stress or sleep, understanding the cause behind this habit helps you respond appropriately and minimize potential complications.In this Dalily Medical article, we will explore the main causes of tongue biting in children and adults, its types, symptoms, risks, diagnosis, and tips for management. We will also cover treatment options, including medications, exercises, surgery, and laser therapy, along with home remedies to relieve pain.
Normal biting: Intermittent, painless, and does not affect eating or speech.
Excessive biting: Persistent, causes sores or pain, and may interfere with eating or speaking → requires medical evaluation.
Rarely, some neurological disorders or genetic syndromes may cause repeated or persistent tongue biting.
If biting persists with other symptoms → a comprehensive medical evaluation is necessary, especially for children.
Yes, it is usually normal, particularly during early infancy or oral exploration.
However, if it is persistent or accompanied by injuries or difficulty breastfeeding → medical follow-up is needed.
Sometimes it is normal in children and adults due to teething, teeth grinding, or nightmares.
If it is frequent or causes tongue injuries → medical consultation is necessary.
Yes, in older children or adults, it often appears due to psychological stress or daily pressure.
Relaxation exercises and habit modification can help reduce this problem.
Usually not, especially if the biting is normal and temporary.
However, if associated with tongue-tie or oral abnormalities → it may affect pronunciation and require treatment.
Persistent sores or ulcers on the tongue.
Difficulty breastfeeding, eating, or speaking.
Continuous or excessive biting during sleep.
Oral infections or repeated bleeding.
Yes, most cases improve with exercises to strengthen the mouth and tongue muscles.
Some rare cases may require medication, surgery, or laser treatment depending on the cause.

Yes, if the child or adult has sores, oral infections, or thrush, they may bite to relieve discomfort.
In infants, it usually appears as part of oral motor development.
In adults, it may occur due to stress, daily habits, or sleep disorders.
Most cases improve by strengthening muscles and modifying habits.
Medical intervention is only necessary if accompanied by persistent ulcers, difficulty eating or speaking, or structural oral issues.
Yes, most cases improve as the child grows or adults adjust their habits.
Medical intervention is required only if the biting persists excessively or causes health problems.
Yes, in severe cases, it may cause:
Repeated sores and ulcers on the tongue.
Oral or gum infections.
Difficulty speaking or chewing in severe cases.
Yes, depending on the cause:
Normal biting: Exercises + habit modification.
Biting due to tongue-tie or abnormalities: Exercises + surgery or laser.
Biting due to pain or thrush: Exercises + medications.
