After a Filling
What to expect after your child’s filling — numbness, sensitivity, eating, and when to call.
- Protect your child’s lip, cheek, and tongue until all numbness is gone
- Avoid very hot foods and drinks while the mouth is numb
- Mild tooth or gum sensitivity can occur after treatment
- Resume normal brushing and flossing unless we told you otherwise
- Call us if the tooth hurts when your child bites, or pain is worsening
What to expect
If local anesthetic was used, your child’s tooth, lip, cheek, or tongue may stay numb for a while after treatment. The tooth or nearby gum may also feel mildly sensitive — sensitivity should generally improve over the following days rather than get progressively worse. A new filling can feel slightly different to the tongue at first; that fades as your child gets used to it.
Protect the numb lip and cheek
Children sometimes bite, chew, scratch, or suck on a numb lip or cheek without realizing they are injuring it. Until feeling has completely returned: remind your child not to chew the lip, cheek, or tongue; hold off on chewy foods if your child cannot reliably feel the area; skip very hot foods and drinks, since temperature is hard to judge while numb; and keep younger children supervised.
The area can swell and develop a white or yellow sore over the next day or two. It can look alarming, but it is usually a bite injury to the soft tissue rather than an infection. Call us if you are unsure what you are looking at, or if swelling or discomfort is significant.
Eating and drinking
Once your child can safely feel and control their mouth, normal eating can usually resume unless we gave you different instructions. If the tooth feels sensitive, softer foods may be more comfortable for the rest of the day.
Pain or sensitivity
Mild sensitivity to chewing or temperature can occur. If pain medicine is needed, use what is appropriate for your child’s age, weight, medical history, and other medications — follow the instructions we gave you and the product’s weight-based dosing directions. Never give aspirin to children.
Brushing and flossing
Continue normal twice-daily brushing with fluoride toothpaste and regular cleaning between the teeth. A filling repairs the damaged part of the tooth — it does not remove the risk of future cavities, so the daily routine matters as much as ever.
Call us if…
- Discomfort is increasing rather than improving
- The tooth hurts every time your child bites, or the filling feels “too tall”
- Spontaneous or nighttime pain develops
- Swelling appears
- The filling breaks or comes out
