Crowns & Pulpotomies

Stainless steel and tooth-colored crowns for teeth too broken down for a filling, and pulpotomies for decay that has reached the nerve.

When does a baby tooth need a crown instead of a filling?

When too little healthy tooth is left for a filling to hold onto. A filling is glued into a hole; if the walls around that hole are thin or already fractured, the filling will fail and you will be back, usually at an inconvenient time.

A crown covers the whole tooth. It is more work up front and it lasts until the tooth falls out on schedule.

What is a pulpotomy?

A pulpotomy is the removal of infected pulp tissue from the top chamber of a tooth, leaving the healthy tissue in the roots intact. People call it a baby root canal, which is close enough, though it is a smaller procedure than an adult root canal.

It is done when decay has reached the nerve. A crown goes on afterward in the same visit.

Silver or white?

Both are available. Stainless steel crowns are stronger, cheaper, and nearly impossible to break, and they are what we recommend for back molars that no one sees. Tooth-colored zirconia crowns look far better and are what most families choose for front teeth. They cost more and are slightly more technique-sensitive to place.

We will show you both and tell you which we would pick for our own kids on that particular tooth.

Questions about this

Do baby teeth with cavities really need to be filled?

Usually yes. Baby teeth hold space for the permanent teeth behind them, and an untreated cavity in a baby tooth can cause pain, infection, and damage to the permanent tooth developing underneath it. A back molar that comes in at age two is not lost until age ten to twelve, so it has to last.

There are exceptions. A small cavity in a front baby tooth that is already loose in a six-year-old may not be worth treating. We will tell you when that is the case. When a tooth does need work, we will show you the photo or the x-ray on the screen and explain what we are seeing before you decide.

Is nitrous oxide safe for children?

Nitrous oxide, sometimes called laughing gas, is the most widely used and best studied form of sedation in pediatric dentistry, and it is safe for healthy children. Your child stays awake and able to talk the entire time. The effect wears off within about five minutes of breathing plain oxygen at the end of the appointment.

Children go back to school the same day and can eat normally. The most common side effect is mild nausea, which is why we ask for a light meal beforehand rather than an empty stomach. Nitrous is not appropriate for children with a blocked nose, certain respiratory conditions, or a recent middle ear surgery, so we go through health history before we use it.
