Yes. If a fracture exposes the inner tooth or allows bacteria to reach vulnerable areas, infection may develop even when there is little initial pain. A dentist can check the damage and determine whether a filling, crown, or additional treatment is needed. 

 Yes, but be gentle around the damaged area. Use a soft-bristled toothbrush and avoid pressing against any loose or sharp sections. Keeping your mouth clean is important while you wait for treatment. If brushing causes significant pain, contact your dentist for advice. 

 You can usually eat soft foods if chewing is comfortable, but avoid biting with the damaged tooth. Hard, sticky, or very hot and cold foods may increase discomfort or cause further damage. If your dentist has given you specific instructions before treatment, follow those instead. 

A fracture extending below the gumline may require more involved treatment. Your dentist will assess how far the break extends and whether enough healthy tooth remains for a restoration. Some teeth can still be repaired, while others may require extraction if the damage is too extensive.
