Visit a dentist if you have any of the below issues or if you see your child having trouble chewing or complaining of soreness:

Problem One: Tooth Decay
Problem Two: Gum Disease (Periodontitis)
Problem Three: Tooth Infection (Root Infection)
Problem Four: Enamel Degradation
Problem Five: Dry Mouth
Problem Six: Temporomandibular Joint Disorder (TMJ)

Dental Problems should not be avoided at any cost. I recommend you to visit Absolute Smile Dentist in Philadelphia for more related information & knowledge.
