Fillings are a way of repairing cavities in teeth. Children are prone to cavities as they are still learning how to brush and floss effectively, making fillings common restorative dentistry procedures for kids. Occasionally fillings come loose and even fall out of the tooth, resulting in sensitivity and sometimes pain.
If your child loses a filling, the best thing to do is keep calm and contact your dentist. A filling can be replaced fairly easily in most cases, but prompt treatment is essential to keep the tooth healthy and avoid infection.
Why Fillings Can Fall Out in Children
Fillings can fall out due to a variety of causes, such as:
- Chewing hard or sticky foods. Sometimes chewing particularly hard or sticky foods can cause a filling to come out of a tooth.
- Teeth grinding. Children who grind their teeth may cause fillings to loosen and fall out.
- Normal wear. The force of daily chewing can wear on the teeth, potentially loosening a filling.
- Natural shedding. Baby teeth that are ready to fall out will sometimes lose a filling as the roots wear down.
Signs Your Child’s Filling Has Fallen Out
It is not always obvious that your child has lost a filling. Look for the following signs and symptoms so you can seek prompt treatment:
- A visible hole in a tooth
- Sensitivity to cold, heat, or sugar
- Pain that does not subside
- Food that keeps getting stuck in the same place
If you notice any of the above, check your child’s mouth carefully with a flashlight and a mirror. When in doubt, contact your dentist.
What Parents Should Do Right Away
If you suspect your child has lost a filling, remain calm. This is a common occurrence, and although prompt treatment is needed, it would not be considered an emergency. Have your child rinse their mouth with lukewarm saltwater to dislodge any food that may be stuck in the open cavity. Advise them not to chew on that side of their mouth and offer over the counter pain medication if needed until you are able to get to the dentist.
Don’t wait to seek professional dental care in case of a lost filling, even if your child is not in pain. The tooth is susceptible to infection due to the missing filling, which could lead to more severe pain and potential loss of the tooth. This is especially important for permanent teeth, as you only get one set in your lifetime.
