Infant teeth grinding, medically known as bruxism, is a common behavior in babies and toddlers. It involves clenching or rubbing teeth together, often producing a noticeable sound. This habit is typically a normal, temporary part of development and usually resolves on its own. While the sound can be alarming, it is generally not a serious concern.
Why Babies Grind Their Teeth
One common explanation relates to teething discomfort. As new teeth emerge, babies experience pressure and soreness, and grinding may alleviate this sensation. This behavior often begins when first baby teeth appear, typically around 5 to 7 months.
Another factor is the exploration of jaw and oral sensations. Babies learn to control jaw movements and discover new textures and sounds with developing teeth. As baby teeth erupt, the jaw is still developing, and grinding might help infants adjust their bite or find a comfortable resting position.
Stress or anxiety can also play a role, though less common than in older children. Changes in routine, new environments, or sleep disruptions might lead a baby to grind teeth as a coping mechanism. A consistent, calming routine can sometimes mitigate this. Underlying issues like ear infections or allergies might also contribute to jaw discomfort, prompting grinding, as ear and jaw nerves are connected.
When to Talk to a Doctor
While infant teeth grinding is often harmless, certain signs indicate professional medical advice may be beneficial. If grinding is persistent, frequent beyond toddler years, or unusually intense, it warrants evaluation. Parents should also look for visible signs of wear, chips, or fractures on the baby’s teeth, as continuous grinding can lead to tooth damage.
If the baby appears to be in pain, shows difficulty eating, or exhibits signs of jaw soreness, a consultation with a pediatrician or pediatric dentist is important. These symptoms could suggest that the grinding is causing discomfort or affecting oral function. Additionally, if grinding is accompanied by other concerning symptoms, such as difficulty sleeping, excessive fussiness, or indicators of an ear infection, a medical professional can help identify any underlying issues. Parents should feel comfortable consulting a healthcare provider for peace of mind, even if no alarming symptoms are present.
Ways to Help Your Baby
Parents can implement several practical strategies to help their baby if they are grinding their teeth. Offering safe teething aids, such as rubber teethers, rings, or a cold, wet washcloth, can help alleviate the discomfort associated with emerging teeth. The pressure from chewing on these items may provide relief and reduce the urge to grind.
Providing gentle comfort, such as a soft jaw massage or cuddling, can also be soothing for the baby. If stress is suspected to be a contributing factor, maintaining a consistent daily and bedtime routine can be beneficial. A calming routine before sleep, including activities like a warm bath or reading a book, can help reduce anxiety. Regular dental check-ups are also important to monitor oral health and tooth development, allowing a pediatric dentist to assess any potential impact of grinding. It is important to avoid using any remedies or devices that have not been recommended or approved by a healthcare professional.
