Do Baby Teeth Really Need Fillings if They’re Going to Fall Out?

It grows, and eventually it reaches the nerve. Enamel on a baby tooth is thinner than on an adult tooth, so decay travels through it faster than most parents expect. What starts as a small dark spot on a molar can reach the pulp chamber in a matter of months rather than years.

Once decay gets that far, the tooth becomes an active infection. Children with an abscessed primary tooth lose sleep, chew on one side, skip meals they used to ask for, and sometimes end up in an emergency visit for facial swelling that a small restoration would have prevented. The bacteria also do not stay put. They cross contact points into neighboring teeth, which is why one untreated molar so often turns into three or four cavities by the next checkup.

Yes, in two separate ways. Every permanent tooth develops directly beneath the primary tooth it will replace, which puts it uncomfortably close to any infection sitting above it.

An abscess at the root of a baby molar can disrupt enamel while the adult tooth is still forming, and the result is a permanent tooth that erupts with white or brown discoloration, soft spots, or pitted enamel that is cavity-prone from the day it arrives. The second problem is spacing. Primary teeth hold the arch open for the teeth coming behind them. When one is lost years early, the neighboring teeth drift into the gap and the permanent tooth has nowhere to go. That is a common route into orthodontic treatment that was never necessary. If a tooth does have to come out ahead of schedule, we plan for that space at the same visit we discuss pediatric tooth extraction.

Usually you cannot tell from the kitchen table, and that is the honest answer. Decay still confined to enamel often looks like nothing at all, while a tooth that already hurts is frequently past the point where a simple repair would have worked. Signs worth calling us about include:

• Chalky white or brown spots that do not brush away
• A reaction to cold drinks, ice cream, or anything sweet
• Chewing on one side, or suddenly refusing a food they used to eat
• Food packing into the same spot over and over
• A pimple-like bump on the gum above a tooth

At a routine checkup, Dr. Salmon inspects each surface and uses X-rays to see between the molars where decay hides. Early demineralization can sometimes be halted with fluoride and a tighter home routine. Once decay has broken through enamel into the softer dentin below, it will not remineralize on its own, and restoring the tooth is the only way to stop it.

We restore cavities with tooth-colored composite, a resin material that bonds directly to the tooth and contains no mercury. It matches the surrounding enamel closely enough that most children never notice which tooth was treated.

Composite handles small and moderate decay well, and with good home care a tooth-colored filling holds up for several years, which is often the rest of that tooth’s working life. When decay has taken out a larger share of the tooth, there is no longer enough healthy structure left to bond to. In those cases we place a pediatric crown instead, either stainless steel on a back tooth or a tooth-colored option where appearance matters more. A crown covers the whole tooth, so it resists a second round of decay far better than an oversized filling would.

Occasionally yes, and we say so when it is true. Removal makes more sense than repair in a few specific situations:

• The tooth is already loose and within months of coming out naturally
• Decay has destroyed so much structure that nothing is left to restore
• Infection has reached the root and threatens the permanent tooth
• An abscess is not responding to treatment

What we will not do is remove a tooth simply because it is the faster option. Every primary tooth we can reasonably save is one less gap to manage and one less reason for braces later. The full set of choices sits under our restorative dental care services, and Dr. Salmon walks parents through the trade-offs of each before anything gets scheduled.

Most fillings take under an hour, and we numb the tooth with local anesthetic so your child won’t feel the work. For most kids, we also use nitrous oxide. It helps them relax and sit comfortably, and it wears off within a few minutes after the mask comes off, so the rest of the day goes on as normal. For children who are very anxious, very young, or need several teeth treated in one visit, we also offer IV sedation and general anesthesia. We always choose the lightest option that will keep your child comfortable.

On cost, most dental plans treat restorative work on baby teeth as a covered benefit rather than an elective one, though coverage percentages and annual maximums vary widely from plan to plan. Our front desk verifies your benefits ahead of the appointment and puts an estimate in writing, so nothing on the statement is a surprise.
