Daytime Tooth Grinding
The short answer
Daytime tooth grinding (awake bruxism) is common in babies and toddlers and is usually a way of exploring new teeth, self-soothing, or expressing concentration or frustration. Unlike nighttime grinding, daytime grinding is often a conscious or semi-conscious habit. Most children outgrow it naturally. It rarely causes tooth damage in young children, and intervention is typically not needed unless it persists past age 5 or causes dental problems.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-3 months
Tooth grinding is not possible at this age since teeth have not yet erupted. Babies may rub their gums together, which can produce a clicking sound, but this is a normal exploratory behavior.
3-6 months
As the first teeth begin to erupt, some babies start grinding them almost immediately. This is a natural way of exploring the new sensations in their mouth. The grinding may coincide with teething discomfort and serves as a form of self-soothing.
6-12 months
Daytime grinding becomes more common as more teeth appear. Babies often grind when they are concentrating, exploring their mouth, or experiencing teething. The sound can be unpleasant, but the behavior is developmental and does not typically cause damage to baby teeth, which have thick enamel relative to their size.
12 months+
Toddlers may grind their teeth during the day when frustrated, anxious, or concentrating. As language and coping skills develop, daytime grinding often decreases. If your toddler grinds frequently and you notice wear on their teeth, mention it at the next dental visit. Stress-related grinding in older toddlers may benefit from addressing the underlying stressor.
What Should You Do?
When to take action
- Your baby grinds their teeth occasionally while playing or exploring
- The grinding happens in phases and is not constant throughout the day
- Your child does not complain of jaw pain and eats normally
- Your dentist sees no significant wear or damage on the teeth
- Daytime grinding is very frequent and seems compulsive rather than occasional
- Your child complains of jaw soreness, headaches, or ear pain
- You notice visible wear patterns or flattening on the biting surfaces of the teeth
- Grinding is accompanied by jaw locking, inability to open the mouth, or severe pain that interferes with eating
- Your child suddenly starts grinding teeth along with other new repetitive behaviors, facial asymmetry, or signs of a neurological change

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
Are Allergies Linked to Neurodivergence in Children?
Research has found statistical associations between atopic conditions (eczema, food allergies, asthma) and certain neurodevelopmental differences such as ADHD and autism spectrum disorder. However, having allergies does not mean your child will be neurodivergent, and most children with allergies develop typically. These conditions may share some underlying immune and genetic pathways, but one does not cause the other.
