Baby teeth have a limited lifespan, but “temporary” does not mean unimportant. An untreated cavity can progress from a small area of decay to deeper inflammation, infection, pain, and potentially early tooth loss. Getting the tooth checked early can make treatment simpler and help protect your child's developing smile. If you have noticed a cavity, dark spot, sensitivity, or swelling, talking to a pediatric dentist in Burlington is a much better option than simply waiting for the baby tooth to disappear. A little attention now can prevent a much harder dental problem later.
