Finding out that your child needs a filling can be worrying for parents. Cavities are common in children, but treating them early prevents pain, infection and problems with adult teeth. Understanding what is involved helps you prepare your child and feel confident about treatment.
Baby teeth help children chew, speak and hold space for adult teeth. Untreated cavities can cause pain, infection and early tooth loss. Treating decay early keeps children comfortable and protects their developing smile.
Tooth-coloured composite fillings are commonly used because they look natural. Glass ionomer fillings release fluoride and may be used in certain situations. Your dentist will choose the most suitable material.
Dentists use numbing gel and local anaesthetic, along with child-friendly explanations and distraction techniques. Treatment is usually quick.
Use positive language and avoid words like hurt or needle. Explain that the dentist will clean the tooth and make it strong again.
Your child may feel numb for a few hours. Watch that they do not bite their lip or cheek. Soft foods are best until numbness wears off.
Brush twice daily with fluoride toothpaste, limit sugary snacks and drinks, and attend regular check-ups.
If decay is extensive, a crown or nerve treatment may be needed.
Early cavities often cause no pain, which is why regular check-ups are so important. As decay progresses, children may complain of sensitivity to sweet, hot or cold foods, avoid chewing on one side, or have food getting stuck in a particular tooth. Parents may notice white chalky spots, brown or black marks or small holes, especially on back teeth or near the gumline of front teeth. If you see any of these signs, book a dental visit rather than waiting for pain.
The dentist first explains each step in simple, friendly language. Numbing gel is applied to the gum before a gentle local anaesthetic if needed. The decayed part of the tooth is removed, and the cavity is cleaned and filled with tooth-coloured material, which is shaped and hardened with a light. The bite is checked so the filling feels comfortable. Most fillings take only a short time, and children are praised throughout for their cooperation.
If your child is nervous, let the clinic know in advance. Short familiarisation visits, tell-show-do techniques, distraction with music or cartoons and plenty of praise can make a big difference. Stay calm yourself, as children pick up on parents' anxiety. For very anxious children or extensive treatment, your dentist may discuss alternatives such as silver diamine fluoride or sedation options.
Fillings in baby teeth usually last until the tooth falls out naturally, provided the child keeps up good brushing and limits sugary snacks. Your dentist will check fillings at each visit and repair them if needed.
