What Types of Fillings Are Best for Children
What Types of Fillings Are Best for Children?
Your child has a cavity. It happens – tooth decay is one of the most common chronic conditions in children, and even kids with solid brushing habits can develop cavities. The important thing is treating it promptly with the right material. But many parents are surprised to learn that not all fillings are the same, and the best choice for a child’s tooth depends on several factors that differ from adult dentistry.
At Little Teeth Big Teeth Pediatric Dentistry in Chicago, Dr. Linda Ruan helps families navigate these decisions every day. This guide breaks down the most common filling types used in pediatric dentistry, when each one is appropriate, and what parents can expect.
Do Baby Teeth Really Need Fillings?
This is the most common question parents ask – and the answer is yes. Even though baby teeth eventually fall out, leaving a cavity untreated creates real problems. Decay spreads, causes pain, and can lead to infection that puts the developing permanent tooth at risk. Premature tooth loss also disrupts spacing, which can cause crowding and alignment issues that may need orthodontic treatment later.
A simple filling, placed early, is almost always faster, less invasive, and less costly than the treatment required once decay has been left to progress. In more advanced cases, a cavity that reaches the inner pulp of the tooth may require a pulpotomy – a procedure sometimes called a “baby root canal” – followed by a crown. Catching decay at the filling stage prevents that escalation.
The Main Types of Fillings for Children
Tooth-Colored Composite Resin
Composite resin is the most widely used filling material in pediatric dentistry today. It is a blend of plastic and fine glass particles that is matched to the natural shade of the tooth, making it virtually invisible. Because it bonds directly to the tooth structure, less healthy tooth material needs to be removed during preparation compared to older metal alternatives.
Composite is a good choice for both front and back teeth. It is particularly preferred for teeth that show when your child smiles. The one practical consideration is that it requires a dry field during placement – which can be more challenging with very young or anxious children. In those situations, Dr. Linda may recommend an alternative material that is easier to work with.
Glass Ionomer Cement
Glass ionomer is a tooth-colored material with a useful property that composite lacks: it slowly releases fluoride over time, providing ongoing protection to the surrounding enamel. It also bonds without needing a completely dry surface, which makes it an excellent option for very young children, for cavities in hard-to-reach areas, or where moisture control is difficult.
It is not as durable as composite under heavy chewing forces, so it tends to be used for smaller cavities, for teeth closer to the front of the mouth, or as a longer-term temporary restoration. Your child’s comfort and cooperation – as much as the clinical picture – guide this decision.
Stainless Steel Crowns
When decay is extensive – covering a large portion of a back molar or following a pulpotomy – a stainless steel crown is often the most reliable option. These prefabricated metal caps fit over the entire prepared tooth, restoring it fully in a single visit. They are exceptionally durable and typically last until the tooth falls out naturally.
They are silver in color, which some parents find unsightly, but their longevity makes them the most cost-effective choice when a large restoration is needed on a baby molar. Research consistently shows that large fillings in primary back teeth have a high failure rate; crowns avoid that problem entirely. For front teeth where appearance matters more, tooth-colored crown options may also be available.
General Dental Fillings Options at a Glance
| Material | Appearance | Best Used For | Key Consideration |
|---|---|---|---|
| Composite Resin | Tooth-colored | Front & back teeth; moderate cavities | Needs dry field during placement |
| Glass Ionomer | Tooth-colored | Small cavities; young children; hard-to-reach areas | Less durable under chewing pressure |
| Stainless Steel Crown | Silver metal | Extensive decay; after pulpotomy; back molars | Visible but extremely durable |
How Dr. Linda Decides Which Filling to Recommend
There is no single right answer that applies to every tooth or every child. Dr. Linda considers the full picture before recommending a material after she evaluates your child’s unique needs and medical history.
The location of the cavity matters. Front teeth that are visible when your child smiles almost always call for a tooth-colored option. Back molars, which take the most chewing force, may need a sturdier restoration.
The size of the cavity is equally important. A small cavity caught at a routine dental check-up can usually be treated with composite or glass ionomer. A cavity that has taken over a large portion of the tooth structure needs a more robust restoration – and often that means a crown.
The child’s age and cooperation also play a role. A cooperative seven-year-old can usually sit still for a composite filling without difficulty. A toddler who is very anxious may benefit from a simpler, faster technique. This is one of the advantages of seeing a specialist – Dr. Linda has the training and experience to select the approach that will produce the best long-term result given the individual circumstances.
Finally, how long the tooth needs to last matters too. A baby molar that will not fall out for another five or six years needs a more durable restoration than one that will exfoliate in six months.
What If a Filling Is No Longer Enough?
Sometimes a cavity is caught too late for a simple filling to be the right solution. If decay has reached the pulp – the inner tissue of the tooth containing nerves and blood vessels – a filling alone will not resolve the problem. In that case, Dr. Linda may recommend a pulpotomy, which removes the affected pulp tissue and seals the tooth before a crown is placed over it.
If decay has progressed so severely that the tooth cannot be saved, a tooth extraction may be the only option. In those cases, Dr. Linda will also discuss whether a space maintainer is appropriate to hold the gap until the permanent tooth comes through.
This progression – from filling to pulpotomy to extraction – is exactly why early treatment matters so much. A small cavity found at a routine check-up is almost always the simplest, least invasive scenario.
Reducing the Risk of Cavities
The best filling is the one that never needs to happen. A few consistent habits at home, combined with regular dental visits, go a long way:
- Brush twice daily with a fluoride toothpaste appropriate for your child’s age
- Floss once a day as soon as two teeth are touching side by side
- Limit sugary drinks and snacks, especially between meals
Ask Dr. Linda about dental sealants – a thin protective coating applied to the grooves of back teeth that can prevent cavities from forming in the first place
Keep up with six-monthly check-ups and professional cleanings
Frequently Asked Questions
No. Dr. Linda uses a topical numbing gel before administering a local anaesthetic, so the tooth preparation should be completely comfortable. Most children are surprised at how straightforward the experience is. Some mild sensitivity in the area is normal for a day or two afterwards.
For baby teeth, a well-placed composite filling is designed to hold until the tooth naturally falls out. Stainless steel crowns are extremely durable and almost always outlast the tooth itself. For permanent teeth, composite fillings typically last five to ten years or more with good oral hygiene.
Absolutely. The team at Little Teeth Big Teeth Pediatric Dentistry is experienced in working with anxious children. Dr. Linda takes a gentle, patient approach and explains each step before it happens. Nitrous oxide (laughing gas) is available for children who need extra support along with possible other sedation options.

Not necessarily. Composite resin looks natural and works well in many situations, but for heavily decayed back molars, a stainless steel crown is clinically superior – more durable, more predictable, and less likely to need retreatment. Dr. Linda will always recommend the material that gives your child the best long-term outcome.
