Your Child's Dentist Says They Need Treatment — Should You Get a Second Opinion?

Few statements from a dentist make a parent's heart drop like hearing that their child needs dental treatment under sedation, multiple fillings, or extraction of baby teeth.Few statements from a dentist make a parent's heart drop like hearing that their child needs dental treatment under sedation, multiple fillings, or extraction of baby teeth.

The statistics on paediatric dental overtreatment are sobering. A landmark study published in *Community Dentistry and Oral Epidemiology* found that when 6- to 12-year-old children were examined by multiple dentists, the treatment recommendations varied so widely that some dentists recommended no treatment at all while others recommended multiple restorations on the same child PubMed: 21317586.

This diagnostic variability means that a significant number of paediatric dental treatment recommendations may be unnecessary — and when the treatment involves general anaesthesia, pulpotomies ("baby root canals"), or stainless steel crowns, the stakes are both medical and financial.This diagnostic variability means that a significant number of paediatric dental treatment recommendations may be unnecessary — and when the treatment involves general anaesthesia, pulpotomies ("baby root canals"), or stainless steel crowns, the stakes are both medical and financial.

Why Paediatric Dentistry Has Such High Variability

The Diagnostic Challenge

Diagnosing cavities in children's teeth is genuinely difficult. Baby teeth are smaller, the enamel is thinner, and children are less able to cooperate with the examination.Diagnosing cavities in children's teeth is genuinely difficult. Baby teeth are smaller, the enamel is thinner, and children are less able to cooperate with the examination.

A 2018 study in the *Journal of the American Dental Association* compared radiographic diagnosis of proximal caries in primary teeth among six paediatric dentists. The agreement between dentists was only moderate, with kappa values ranging from 0.41 to 0.63 depending on tooth type and surface PubMed: 29961619.

This means that whether your child "needs" treatment may depend more on which dentist examines them than on the actual condition of their teeth.This means that whether your child "needs" treatment may depend more on which dentist examines them than on the actual condition of their teeth.

The Watch-and-Wait Gap

For adult patients, there is a well-established category of "watchful waiting" for small enamel-only lesions. In paediatric dentistry, the threshold for treating versus monitoring varies enormously between practitioners.For adult patients, there is a well-established category of "watchful waiting" for small enamel-only lesions. In paediatric dentistry, the threshold for treating versus monitoring varies enormously between practitioners.

Some dentists recommend filling any visible decalcification, citing the rapid progression of caries in children. Others argue that these early lesions can remineralise with fluoride and dietary changes. A Cochrane review of sealants versus fillings for initial caries in children found that sealants were effective at preventing progression of early lesions, with no clear advantage of invasive restorative treatment Cochrane: 2016.

The Treatment Recommendations Most Likely to Be Unnecessary

Stainless Steel Crowns on Baby Teeth

Stainless steel crowns (SSCs) on primary molars have become one of the most controversial topics in paediatric dentistry.Stainless steel crowns (SSCs) on primary molars have become one of the most controversial topics in paediatric dentistry.

Evidence from the American Academy of Paediatric Dentistry (AAPD) supports SSCs as the treatment of choice for multi-surface caries in primary molars AAPD Guidelines. However, research shows significant variation in their use. Some practitioners fit SSCs for cavities that could be treated with a filling, and the rate of SSC placement varies by geographic region by as much as 400%.

A 2017 study in *Pediatric Dentistry* found that 23% of stainless steel crowns placed in a Medicaid population showed no radiographic evidence that a filling was insufficient — suggesting potential overtreatment PubMed: 28659160.

Before agreeing to SSCs, ask whether a large filling or composite crown is an alternative.Before agreeing to SSCs, ask whether a large filling or composite crown is an alternative.

Pulpotomies (Baby Root Canals)

A pulpotomy involves removing the infected portion of the pulp from a primary tooth while leaving the healthy root pulp intact. It is indicated when decay has reached the pulp chamber.A pulpotomy involves removing the infected portion of the pulp from a primary tooth while leaving the healthy root pulp intact. It is indicated when decay has reached the pulp chamber.

A 2019 study found that inter-dentist agreement on when a pulpotomy was needed ranged from poor to moderate, even among paediatric dentists PubMed: 31545790.

If your child's dentist recommends a pulpotomy, ask to see the X-ray evidence of pulp involvement before proceeding.If your child's dentist recommends a pulpotomy, ask to see the X-ray evidence of pulp involvement before proceeding.

General Anaesthesia for Simple Fillings

The recommendation for general anaesthesia (GA) for routine paediatric dental treatment is perhaps the most controversial area. GA carries real medical risks and adds $1,500 to $5,000 to the cost of treatment.The recommendation for general anaesthesia (GA) for routine paediatric dental treatment is perhaps the most controversial area.

How to Get a Reliable Paediatric Second Opinion

1. Choose the Right Provider

The ideal second-opinion provider is a paediatric dentist not affiliated with the original practice. Paediatric dentists complete two to three years of additional residency training focused on child development and treatment of primary teeth.The ideal second-opinion provider is a paediatric dentist not affiliated with the original practice.

FAQ

When should I seek a second opinion for my child's dental treatment?

Consider a second opinion if the recommended treatment includes stainless steel crowns for primary teeth, extractions, pulpotomies, treatment under general anaesthesia, or multiple fillings (four or more). Also seek a second opinion if you cannot see the cavities on the X-ray yourself.Consider a second opinion if the recommended treatment includes stainless steel crowns for primary teeth, extractions, pulpotomies, treatment under general anaesthesia, or multiple fillings (four or more).

Can baby teeth with cavities fall out without treatment?

Baby teeth with small, non-painful cavities in children under 6 may sometimes exfoliate before the cavity causes problems. However, cavities in baby molars that will remain for 2-4 more years can progress to abscesses, risking damage to the developing permanent tooth.Baby teeth with small, non-painful cavities in children under 6 may sometimes exfoliate before the cavity causes problems. However, cavities in baby molars that will remain for 2-4 more years can progress to abscesses, risking damage to the developing permanent tooth.

Is general anaesthesia safe for my child's dental treatment?

General anaesthesia is generally safe for healthy children when administered by a qualified anaesthetist. However, regional variation in its use far exceeds clinical need, so ask whether less invasive approaches are feasible alternatives.General anaesthesia is generally safe for healthy children when administered by a qualified anaesthetist.

When Extraction of a Baby Tooth Is Actually the Right Call

There are situations where extracting a primary tooth is genuinely the best option:There are situations where extracting a primary tooth is genuinely the best option:

1. The decay has destroyed too much tooth structure to support a crown 2. There is an abscess that antibiotic treatment alone will not resolve 3. The baby tooth is preventing the permanent tooth from erupting (over-retained primary tooth) 4. The permanent successor is close to erupting (within 6 months radiographically) 5. Severe infection that threatens the permanent tooth bud1. The decay has destroyed too much tooth structure to support a crown 2.

Silver Diamine Fluoride: The Drill-Free Alternative

Silver diamine fluoride (SDF) is a minimally invasive treatment option that is transforming paediatric dentistry. In 2014, the FDA cleared SDF for treating dentin hypersensitivity, and it is now widely used off-label for arresting caries in children.Silver diamine fluoride (SDF) is a minimally invasive treatment option that is transforming paediatric dentistry.
