Understanding Your Recovery
Most children's visits are a cleaning, an exam and a fluoride treatment, sometimes with sealants on the back teeth, and occasionally a filling. The care afterward is simple, but one rule matters more than the rest: if your child was numbed, watch their lip and cheek until the feeling returns. Young children often chew or suck on a numb lip without feeling it. In a study of children treated with local anesthesia, about one in eleven children without a disability bit themselves afterward, most often children six and under and most often on the lower jaw (Bagattoni et al., European Archives of Paediatric Dentistry, 2020).
A bite like that looks alarming, with a swollen, white or raw patch on the lip, but it heals on its own in a week or two with gentle cleaning and soft foods. Keep your child from chewing until the numbness is gone, usually one to two hours, offer only cool drinks and smooth foods in the meantime, and remind them not to bite or suck the lip. Call us if the area is large, bleeding, or not healing after a week.
Fluoride varnish and sealants need almost nothing from you. Varnish is painted on and sets on contact with saliva; for the rest of the day keep to soft foods and cool drinks, and wait until the next morning to brush, unless we give you different instructions for the product we used. The teeth may look a little yellow or dull until that first brushing. Sealants are hardened in the chair, so your child can eat right away; if a sealed tooth feels 'high' when they bite for more than a day or two, call us and we will smooth it.
The visit is also when we reset home habits, and the guidance is consistent across the American Dental Association, the American Academy of Pediatric Dentistry and the NHS: brush twice a day with a smear of fluoride toothpaste the size of a grain of rice under age 3 and a pea-sized amount from 3 to 6, floss as soon as two teeth touch, help with brushing until at least age 7, keep sugary drinks out of bottles and bedtime, and come back every six months.
After the Visit, Step by Step
The First Few Hours
If Your Child Was Numbed
- Keep an eye on the lip and cheek until feeling returns, usually one to two hours; children often chew a numb lip without noticing.
- No chewing until the numbness is gone. Cool drinks and smooth foods such as yogurt or applesauce are fine.
- Remind your child not to bite, suck or pull at the numb lip, and keep fingers out of the mouth.
- If they do bite the lip, it may swell and turn white; clean it gently and keep to soft foods. It heals in a week or two.
What to expect: A puffy, tingly lip and cheek on the treated side, and sometimes drooling or slurred speech until the anesthetic wears off.
The Rest of the Day
After Fluoride Varnish or Sealants
- After fluoride varnish: soft foods and cool drinks for the rest of the day, no brushing until the next morning, unless we told you otherwise for the product we used.
- The varnish can make the teeth look slightly yellow or feel sticky until the first brushing; that is the varnish, not stain.
- After sealants: your child can eat normally right away.
- If a sealed or filled tooth feels high when your child bites, give it a day or two to settle, then call us for a quick adjustment if it still does.
What to expect: No discomfort from varnish or sealants. A new filling may be mildly sensitive to cold for a few days.
The First Week
After a Filling or an Extraction
- Mild sensitivity after a filling should fade over a few days; children's acetaminophen or ibuprofen, dosed by weight as the package or your pediatrician directs, is enough if anything is needed.
- If a baby tooth was removed, follow the extraction instructions we gave you: gentle pressure on gauze for bleeding, soft foods, and no straws or vigorous rinsing the first day.
- Brush the other teeth as usual and gently around the treated tooth from the next day.
- Call us about pain lasting more than two days, swelling, fever, or a filling that falls out.
What to expect: Children usually bounce back within a day. Sensitivity that fades is normal; pain that grows is not.
Every Day
Home Care by Age
- Under 3: brush twice a day with a smear of fluoride toothpaste the size of a grain of rice; you do the brushing.
- Ages 3–6: a pea-sized amount of fluoride toothpaste, twice a day; your child can start, you finish, and they should spit rather than rinse.
- Floss between any two teeth that touch, and keep helping with brushing until at least age 7.
- Water or plain milk only in bottles and at bedtime; keep juice and sweet drinks to mealtimes, and come back every six months.
What to expect: Habits set now carry into the adult teeth. We will adjust the plan at each visit as your child grows.
Do’s and Don’ts
Do
- Watch a numb lip and cheek until feeling returns, and keep chewing off the menu until then
- Offer soft foods and cool drinks for the rest of the day after fluoride varnish, and brush the next morning
- Use a rice-grain smear of fluoride toothpaste under age 3 and a pea-sized amount from 3 to 6
- Help with brushing until at least age 7, and floss where two teeth touch
- Give children's acetaminophen or ibuprofen dosed by weight if your child is sore
- Keep water as the only drink in bottles and at bedtime
- Book the next visit six months out before you leave
Don’t
- Do not let your child chew, bite or suck on a numb lip or cheek
- Do not give hot drinks or foods that need chewing until the numbness is gone
- Do not brush right after fluoride varnish; wait until the next morning unless we said otherwise
- Do not give aspirin to children for dental pain
- Do not put juice, milk or anything but water in a bedtime bottle
- Do not try to put a knocked-out baby tooth back in its socket; call us instead
Diet Guidance
While Numb
Safe to Eat
- Cool water
- Smooth foods that need no chewing: yogurt, applesauce, a smoothie without a straw if a tooth was removed
Avoid
- Anything chewy or crunchy
- Hot foods and drinks
- Gum and candy
Rest of the Day After Fluoride Varnish
Safe to Eat
- Soft foods: pasta, eggs, bananas, soup that is warm rather than hot
- Cool drinks
Avoid
- Hard, crunchy or sticky foods
- Hot drinks
- Brushing until the next morning
Every Day

- Water and plain milk as the main drinks
- Fruit, vegetables, cheese and whole foods as snacks
Avoid
- Juice and sweet drinks outside mealtimes
- Sticky sweets and dried fruit between meals
- Anything but water in a bedtime bottle
Pain Management
Most children's visits need no pain relief at all
If your child is sore after a filling or extraction, children's acetaminophen or ibuprofen dosed by weight as the package or your pediatrician directs is enough; never give aspirin to a child
A cold compress on the cheek for 10–15 minutes at a time eases swelling after an extraction
A bitten lip heals with gentle cleaning and soft foods; a little petroleum jelly on the outside keeps it from cracking
When to Contact Us
Contact us immediately if you experience
- A bitten lip or cheek that is large, bleeding, or not healing after a week
- Swelling of the face or jaw, or a fever
- Pain lasting more than two days after a filling or extraction
- Bleeding after an extraction that does not stop with 20 minutes of firm pressure on gauze
- A filling or sealant that has come out, or a tooth that still feels high after two days
- A knocked-out or badly chipped permanent tooth: find the tooth, hold it by the crown, keep it in milk and call us immediately
Emergency note: Children's visits rarely cause emergencies. Call us right away for facial swelling, fever, bleeding that does not stop with 20 minutes of pressure, or a knocked-out permanent tooth. For swelling that affects breathing or swallowing, or a head injury, go to the nearest emergency room.
