If your child needs a filling, it’s completely normal to want to know what the appointment will actually involve — for their sake and for your own peace of mind. Many parents find that once they understand the steps, it’s much easier to explain the visit to their child in a calm, matter-of-fact way. Fillings are one of the most common treatments in paediatric dentistry, and most children manage them very well, especially when they know what to expect. Here’s a plain-English walkthrough of a typical filling appointment at Tooth Town.
Why a filling is needed
A filling is used when decay has created a small hole, or cavity, in the tooth. Once decay has broken through the outer surface of the tooth, it won’t repair itself, and the affected part needs to be cleaned out and sealed to stop it from progressing further and to protect the healthy tooth structure around it. Your child’s clinician will have already explained why a filling is the right next step for their tooth, and will talk you and your child through the plan again on the day.
Before we start: examination and explanation
Every filling appointment begins with a quick check of the tooth and a simple explanation of what’s about to happen. Our team uses a calm, child-friendly approach often called “tell-show-do” — we tell your child what we’re going to do, show them (using friendly, age-appropriate language and sometimes the instruments themselves), and only then do it. This helps children feel informed and involved, rather than surprised by each step. We’ll also check in with you about anything specific to your child, such as previous experiences, sensitivities or ways they like to be supported.
Making the area comfortable
Before working on the tooth, the area usually needs to be numbed so your child doesn’t feel the treatment. A numbing gel is often used first to make the injection more comfortable, and your child’s clinician will explain each step as they go, using gentle, honest language rather than surprising your child. Every child experiences this a little differently — some children barely notice, while others need a bit more reassurance and time. Our team is experienced in helping children through this part of the appointment at their own pace.
Removing the decay
Once the area is comfortably numb, the decayed part of the tooth is carefully removed. This is usually done with small, gentle instruments designed for this exact job. Your child won’t feel pain during this step, though they may notice some vibration, pressure, water, or sounds, which we’ll explain beforehand so nothing feels unexpected.
Cleaning and preparing the tooth
After the decay has been removed, the tooth is cleaned and prepared so the filling material can bond well and seal the tooth properly. This step helps make sure the filling lasts and the tooth is properly protected going forward.
Filling the tooth
The tooth is then filled using a tooth-coloured or other material appropriate for your child’s specific tooth and situation. Your child’s clinician will have already discussed which type of filling material is most suitable, based on the location and extent of the decay, when they explained the treatment plan.
Checking the bite
Once the filling is in place, your child’s clinician checks their bite to make sure the filling feels comfortable and sits at the right height when they close their teeth together. Your child may be asked to bite down gently on a small piece of paper a few times so this can be checked and adjusted if needed.
What your child might feel afterwards
It’s common for the numbness to last for a little while after the appointment, and your child may notice their lip, cheek or tongue feels strange or “puffy” until it wears off. Mild sensitivity around the filled tooth can also occur and is usually temporary. Every child recovers a little differently, and your child’s clinician will let you know if there’s anything specific to watch for based on their treatment.
Simple aftercare
While the numbness is still present, it’s best to avoid very hot food or drinks, and to keep an eye on your child so they don’t accidentally bite their cheek, lip or tongue without realising it — this is a common and easily avoidable mishap while the area is still numb. Once the numbness has fully worn off, your child can generally go back to eating and drinking normally, unless you’ve been given different instructions for their specific treatment.

A note on comfort options
Most children manage a filling appointment very well with the approach described above. For some children, additional comfort options such as happy gas (relative analgesia) may be discussed with families where appropriate. This isn’t offered as a standard part of every filling, and whether it’s suitable will depend on your child’s individual needs — your child’s clinician is happy to talk this through with you if it’s something you’d like to discuss.
Frequently asked questions
Will my child feel pain during the filling?
The tooth is numbed before treatment begins specifically so your child shouldn’t feel pain during the procedure itself. Some children feel a brief pinch or pressure during the numbing step, and our team works gently and explains each step as they go to help your child feel as comfortable as possible.
How long does a filling appointment usually take?
This depends on the tooth and the extent of the decay, so it’s best to ask your child’s clinician what to expect for your child’s specific appointment.
Can I stay with my child during the filling?
Yes. You’re welcome to stay with your child for their filling, and for any appointment at Tooth Town. The only time parents aren’t permitted to stay is during treatment under general anaesthesia, where this isn’t allowed in the hospital operating theatre, in line with national standards across all hospitals.
What if my child is very anxious about the appointment?
Please let us know beforehand so we can plan extra time, use additional reassurance techniques, and talk with you about options that might help your child feel more at ease.
Will the filling need to be replaced later on?
Fillings in baby teeth and permanent teeth can last for varying amounts of time depending on the tooth and how it’s cared for. Your child’s clinician will let you know if and when it should be checked again as part of their regular reviews.
What should I tell my child before the appointment?
Simple, honest language works best — for example, letting them know the dentist will look after their tooth and explain everything before it happens. Avoid words like “hurt”, “needle” or “drill” unprompted, as these can create worry that isn’t necessary. Our team is happy to help find the right words if you’re unsure.
