Question:

My 7-year-old boy (weighing 21kg) has a lower front baby tooth that is slightly loose, and I can see a permanent tooth trying to push through right behind it. He is complaining of a toothache. Is it okay to give him dexibuprofen syrup for the pain? If so, could you tell me the correct dosage for his weight?

Answer:

You must be worried as your child is experiencing discomfort while his baby tooth is loose and the permanent tooth is erupting.

【Current Situation】

7-year-old boy, 21kg, loose lower front baby tooth + permanent tooth erupting behind it + complaining of toothache.

【Reassurance Point】

It is a common process for a permanent tooth to erupt behind a baby tooth. In most cases, the baby tooth will fall out naturally, and the permanent tooth will move into its proper place. The pain is likely due to pressure on the gums.

【Dexibuprofen Syrup Dosage (based on 12 mg/mL concentration)】

• 21 kg × 5–7 mg/kg = 105–147 mg

• Converted to syrup volume: 8.8–12.3 mL → approximately 9–12 mL

• Give every 6–8 hours, up to a maximum of 4 times a day.

• Please make sure to measure accurately using a measuring cup or syringe.

【What You Can Do at Home】

• Have him hold cold water or an ice chip in his mouth (to soothe the gums).

• Provide soft foods (porridge, yogurt, fruit puree).

• Gargle with lukewarm salt water after brushing (optional).

• Even if the baby tooth is very loose, do not force it out; wait for it to fall out naturally.

【When to Visit a Dentist】

• The baby tooth remains loose for more than 2 weeks without falling out, and the permanent tooth continues to grow behind it.

• The gums are severely swollen, or there is pus/bleeding.

• The pain is not controlled by painkillers.

• The position of the permanent tooth looks significantly crooked.

→ In these cases, consider visiting a pediatric dentist for a baby tooth extraction or an orthodontic consultation.

For today, make him comfortable using the painkiller and monitor the natural shedding process of the baby tooth. If there is no change after 2 weeks, please consider visiting a dental clinic.
