How to Know if Your Baby Is Teething vs. Having Dental Pain

Your baby is fussier than usual, drooling constantly, and chewing on everything within reach, but is it teething, or is something more serious going on in that tiny mouth? For parents in Las Vegas, distinguishing between normal teething discomfort and actual dental pain can feel overwhelming, especially when your baby cannot tell you what hurts.

At All Star Kidz Pediatrics, Dr. Christopher Lamb and our team are dedicated to helping families in Centennial Hills and throughout the Las Vegas area navigate every stage of childhood dental development. As a Diplomat of the American Board of Pediatric Dentistry, Dr. Lamb provides board-certified care from infancy through adulthood. Learning about early dental care for your little one is one of the most important steps you can take as a new parent.

What Normal Teething Looks Like

Most babies begin teething around 6 months of age, though the timeline can vary from child to child. The process continues until all 20 primary teeth come in, typically by age 3. During this time, some degree of discomfort is expected as teeth push through the gumline.

According to a 2022 study published in BDJ Open via PubMed Central, the most commonly reported teething signs include gingival irritation, irritability, and drooling, with these symptoms documented in the majority of cases studied. Other typical signs to watch for in a teething baby include:

  • Excessive drooling: A surge in saliva production is one of the earliest and most reliable teething indicators, sometimes leading to a mild rash around the chin or cheeks.
  • Chewing on objects: Babies instinctively apply pressure to their gums to relieve discomfort, which is why they gnaw on toys, fingers, and anything else nearby.
  • Fussiness: A general increase in crankiness is expected, particularly in the days leading up to a new tooth breaking through.
  • Gum swelling: Mild redness or puffiness along the gumline where a tooth is emerging is completely normal.
  • Slight temperature rise: Teething can cause a very minor uptick in body temperature, but it should never reach true fever levels of 100.4°F or higher.

These symptoms typically appear a few days before a tooth comes in and resolve on their own once it breaks through the surface.

When It Might Be More Than Teething

Teething is a localized process and does not cause serious systemic symptoms. If your baby is running a high fever, crying inconsolably for extended periods, or showing signs of distress you cannot soothe, something beyond normal teething may be at play. Actual dental pain in infants can stem from early tooth decay, an oral infection, or mouth trauma.

Red Flags Worth Taking Seriously

Signs worth evaluating further include persistent inconsolable crying with no relief from typical soothing methods, visible dark spots or discoloration on newly erupted teeth, and swelling concentrated in one specific area rather than broadly along the gumline. Notable sensitivity when a particular spot in the mouth is gently touched is also a signal to watch for. 

A high fever accompanied by oral discomfort is another key warning sign, because a true fever is not a teething symptom. When these signals appear, reaching out about pediatric dental emergencies promptly is always the right decision.

How Early Cavities Can Look Like Teething

Early childhood tooth decay can develop quickly once the first teeth come in, and the fussiness it causes is often confused with routine teething irritability. Babies who fall asleep with a bottle or are frequently exposed to sugary liquids are at elevated risk for decay, even in their earliest teeth. Routine checkups and cleanings beginning around your child’s first birthday allow Dr. Lamb to detect decay early, before pain becomes a real problem.

How to Soothe a Teething Baby Safely

When teething is confirmed as the source of your baby’s discomfort, there are several safe and effective ways to help ease it. Gently rubbing the gums with a clean finger or a chilled (not frozen) teething ring can provide meaningful relief. Age-appropriate pain relievers like acetaminophen may also be used with guidance from your pediatrician. It is important to avoid benzocaine-containing teething gels and amber teething necklaces, as health authorities have raised safety concerns about both for use in infants.
