Your dentist can help diagnose and treat common dental problems in kids, including: Tooth Decay – can lead to sensitivity, pain, and gum issues. Keep track of when and how well your child brushes. Gingivitis – is a precursor to gum disease. Speak to your dentist if your child’s gums bleed when brushing and flossing. Thumb Sucking – if long-term, can cause an open bite and problems with eating and talking. Broken/Chipped Teeth – ensure your child wears a mouth guard when playing sports and seek treatment for broken/chipped teeth. Orthodontic Issues – your dentist may refer you to an orthodontist for these issues.
