Your Care Instructions

Parts of the mouth

Mouth injuries are common in children. They may involve the teeth, jaw, lips, tongue, inner cheeks, or gums. A mouth injury can also affect the roof of your child's mouth, neck, or tonsils.

Your child may injure his or her teeth during a fall. An injury can crack, chip, or break a tooth or make a tooth change colour. A tooth also may be knocked out, loosened, moved, or jammed into the gum.

An injury to the roof of your child's mouth, the back of your child's throat, or a tonsil can injure deeper tissues in your child's head or neck. These injuries can happen when a child falls with a pointed object, such as a pencil, in his or her mouth. Make sure that your child doesn't walk or run with objects in his or her mouth. This will help keep your child safe.

Your child also may bite his or her tongue because of a seizure, a car crash, or another injury.

A cut or tear to the tongue can bleed a lot. Small injuries may often heal on their own. If the injury is long or deep, it may need stitches that dissolve over time.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Apply a cold compress to the injured area. Or have your child suck on a piece of ice or a flavoured ice pop.
  • Rinse your child's wound with warm salt water right after meals. Saltwater rinses may relieve some pain. To make a saltwater solution for rinsing the mouth, mix 1 tsp of salt in 1 cup of warm water.
  • Have your child eat soft foods that are easy to swallow.
  • Avoid giving your child foods that might sting. These include salty or spicy foods, citrus fruits or juices, and tomatoes.
  • If a jagged tooth or orthodontic wire or bracket is poking your child, roll a piece of melted candle wax or orthodontic wax and press it onto the part that is poking. Use a pencil eraser to press a broken wire toward the teeth. These are only short-term measures to use until you can see your child's dentist or orthodontist to fix the problem.
  • Be safe with medicines. Give pain medicines exactly as directed.
    • If the doctor gave your child a prescription medicine for pain, give it as prescribed.
    • If your child is not taking a prescription pain medicine, ask the doctor if your child can take an over-the-counter medicine.
  • If the doctor prescribed antibiotics for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
  • Try using a topical medicine, such as Orabase, to reduce mouth pain. If your child is under 2 years of age, ask your doctor if your child can use this medicine.
