Here are some measures you can take to assist your child in case of a dental emergency:

Knocked-out baby tooth: If uncertain, contact your pediatric dentist promptly. Do not attempt to reinsert the baby tooth to prevent potential damage to the developing adult tooth.

Knocked out permanent tooth: Locate the tooth and rinse it gently with milk (avoid scrubbing or using soap). If possible, place the tooth back in the socket immediately and hold it in place with clean gauze or a washcloth. If reinsertion is not possible, store the tooth in a clean container with cold milk, saliva, or water. Call your pediatric dentist's after-hours number and make your way to the dental office as quickly as possible.

Chipped or fractured tooth: Contact your pediatric dentist for guidance. For significant fractures reaching the tooth nerve, quick action may help prevent infection and reduce the need for extensive dental treatment. Rinse the mouth with water and apply cold compresses to reduce swelling if there is a lip injury. If you find the broken tooth fragment, place it in cold milk and bring it with you to the dental office.

Toothache: Schedule an appointment with your dental office at the earliest availability. Administer over-the-counter children's pain medication according to your child's weight and age to alleviate symptoms. Applying a cold compress or ice wrapped in a cloth to the affected area may also help with pain relief, but avoid applying heat or aspirin.

Loose appliance, wire, or band: Contact your dental office to arrange an appointment. If the appliance completely comes out, avoid attempting to reinsert it. If it's loose on one side, advise your child to avoid chewing on that side to minimize discomfort and prevent further damage until they can be seen by a pediatric dentist.

A significant blow to the head or jaw: Seek immediate medical attention as a severe head injury can be life-threatening. Remember that emergency medical teams may arrive faster than your ability to reach the hospital. Contact your dental office when your child requires urgent dental treatment. If it is after-hours, utilize the emergency number provided by your dental office's answering service. 

Always consult with your pediatric dentist for specific instructions and guidance tailored to your child's dental emergency.
