My child needs 8 fillings — should I get a second opinion?
Hearing that your child needs many fillings is overwhelming — and it's completely reasonable to ask questions, see the x-rays, and get a second opinion before deciding.

Hearing “your child needs eight fillings” at a routine visit is a lot to take in. Take a breath: this situation is more common than it sounds, you usually have time to ask questions, and wanting to understand the plan doesn’t make you a difficult parent.
Why a child can need several fillings at once
- Baby-tooth enamel is thinner than adult enamel, so decay moves faster once it starts.
- Decay spreads between touching teeth. One cavity between two molars often means a matching cavity on the neighboring tooth.
- Between-teeth cavities don’t show by looking. They usually appear only on x-rays — which is why a child with no visible spots and no complaints can still have a long treatment plan.
- It can happen despite good brushing. Tight contacts between teeth, frequent snacking or sipping, and each child’s individual cavity risk all play a role.
None of this means you did something wrong. It means the decay was found — and now you get to decide what to do about it.
It’s completely reasonable to ask questions
You’re entitled to understand the plan before agreeing to it. Good questions to ask:
- “Can you show me each cavity on the x-ray?” — ask to see the films or photos, tooth by tooth.
- “What’s the reason for each tooth?” — which cavities are deep, which are early?
- “What happens if we wait on some of these?” — which teeth need treatment now, and which could be monitored?
- “Are there alternatives for any of these teeth?” — for example, silver diamine fluoride or staged treatment.
- “How will my child be kept comfortable?” — and how many visits will this take?
A dentist who is confident in the diagnosis will be glad to walk you through it.
Getting a second opinion is normal
If the plan feels like more than you expected, a second opinion is a reasonable next step — not an insult to the first dentist.
- Ask for copies of the x-rays (you’re entitled to them) so the second dentist reviews the same evidence rather than re-taking everything.
- Don’t announce the answer you’re hoping for — just ask the second dentist what they see and what they’d recommend.
- Two honest dentists can differ on early cavities: one may recommend filling, another monitoring. Both can be defensible — the point is understanding the reasoning.
Your options, without judgment
Depending on what the x-rays show, the realistic paths usually include:
- Treat as recommended — sensible when cavities are established or deep, since decay in baby teeth can progress to pain or infection.
- Treat in stages — handle the most urgent teeth first and re-check the rest.
- Monitor early spots — some very early cavities can be watched at regular check-ins, with diet and hygiene changes to slow them down.
- Ask about silver diamine fluoride (SDF) — a liquid a dentist can apply to slow or arrest decay in some baby teeth. It darkens the treated spot, and it isn’t right for every tooth, but it can buy time for a young child.
There’s no shame in any of these choices. The goal is a plan you understand and your child can tolerate.
Why treating baby teeth matters
It’s fair to wonder why baby teeth need fillings at all if they fall out anyway. Baby teeth hold space for adult teeth, and untreated decay can cause pain, infection, and damage to the developing adult tooth underneath. Which teeth matter most, and for how long, depends on your child’s age — another good question for the dentist.
Preventing the next round
Whatever you decide about treatment, lowering future cavity risk helps:
- Water or plain milk instead of juice, soda, and sports drinks — frequent sugary sips are a major driver of early childhood decay.
- Help with brushing until your child can do it well on their own — most young kids need an adult to follow up.
- Floss where teeth touch — that’s where these surprise cavities form.
- Use a fluoride toothpaste in the amount your dentist recommends for your child’s age.
- Ask about sealants for the chewing surfaces of molars.

Frequently asked questions
Is it normal for a child to need 8 fillings?
It happens more often than parents expect. Early childhood decay can spread quickly between teeth, and cavities between teeth usually only show up on x-rays — so a treatment plan can come as a surprise even when nothing looked wrong. It's still reasonable to ask the dentist to walk you through each tooth.
Should I get a second opinion on my child's dental work?
If you're unsure, yes — getting a second opinion is a normal, reasonable step, and a good dentist won't be offended. Bring the x-rays from the first visit so the second dentist can look at the same evidence.
Are there options besides drilling and filling every tooth?
Sometimes. Depending on the tooth and how far the decay has progressed, a dentist may discuss monitoring early spots, applying silver diamine fluoride to slow decay, or treating in stages. Ask which teeth need treatment now and which could be watched.
