My dentist says my child needs a crown or a root canal on a baby tooth. What are these and are they really necessary?

Children are not just little adults and so we can’t treat them as such. Baby teeth are shaped much different than adult teeth, which causes some need for modification when treating them. Because of the shape of baby teeth, we cannot place anything but a very small filling in them, otherwise the filling will break and a new cavity will be created.

The guidelines for treating baby teeth are that if a cavity is of moderate or larger size, a procedure called a “stainless steel crown” is done. This little, silver crown or “cap” is glued down over the existing tooth (after it is specially prepared for it). By having this fairly strong metal covering the entire surface of the tooth, the underlying tooth and filling is protected from breaking from the forces of chewing. As mentioned earlier, a filling or stainless steel crown is usually only needed on a baby tooth which is not due to fall out on its own any time soon. The dentist will evaluate the extent of root development on the underlying permanent tooth with an x-ray. This information, combined with the patient’s age, will be used to determine the approximate amount of time until the baby tooth would likely fall out on its own. If the dentist feels that it will be less than six to nine months, they may recommend no treatment of the tooth unless there is infection present. In this case, they may elect to proceed with the crown (and baby root canal) or simply extract the baby tooth.

This stainless steel crown is similar to a crown or “cap” that an adult may have, except that it is cheaper and meant to come out when the baby tooth falls out. They are usually silver but occasionally for cosmetic reasons can be tooth-colored when needed on front teeth. If your child needs a crown on a baby tooth in the front, be sure to tell your dentist BEFORE the start of the procedure if you want it tooth-colored. They won’t always ask and once it is placed it is usually not easily removed.

 
A stainless steel crown may or may not also have a root canal done at the same time. Yes-baby teeth can have a root canals done on them. Once again though, the concept is different from an adult tooth. Your dentist may call the root canal by several names (each meaning something slightly different to the dentist but making no real difference to you as a parent). Some of those names you may hear are: root canal, pulpotomy, pulpectomy, pulpal debridement and pulp therapy. There are others, but these are the most commonly used.

A root canal in simple terms is the removal of nerve or pulp tissue from the inside of the tooth. It can be removed for many reasons, but for children it is usually done because of a cavity that extends into the pulp/nerve tissue or because of a dead nerve/pulp that is causing an abscess. Baby tooth root canals are different from adult teeth in a few ways. Unlike permanent teeth root canals, those performed on baby teeth do not usually have the rubberized material placed in the canals afterward. They usually only receive a sedative paste which hardens inside the tooth and keeps the infection away. This material is also easily deteriorated by the body as the roots of the baby teeth resorb away and prepare for eruption and loss. They are not as exact of a procedure as root canals on permanent teeth and take much less time. They are not painful and nowhere near as expensive.

So, we can see that sometimes both procedures may be done simultaneously or independently, depending on the child’s unique situation. Your dentist should discuss options with you and don’t be afraid to ask questions. You are your child’s advocate and so you should always attempt to keep yourself informed of any procedure being done

So, what happens if you don’t have the root canal or don’t treat the tooth in any way? Well, if you refuse treatment and also refuse then to have the baby tooth taken out, many things can happen, most of which are bad. The child can end up in the hospital with an infection, particularly if the child is diabetic. I have been unfortunate to have been witness to this and it is truly heartbreaking for me. Not only is this sad for the child, but it puts the dentist in an uncomfortable situation regarding appropriate care and treatment of a child. Proper authorities have to be notified if the child is put in danger. Thankfully this is not extremely common but it does occur.

If hospitalization does not occur, then the abscess will find a way to drain, usually by a small hole made in the gum to relieve pressure and drain puss-right into the mouth. This can cause bad breath and an upset stomach, not to mention it is just disgusting. The other major concern is that an infection left in the tooth can cause damage to the permanent tooth below the offending tooth. Damage may appear as a misshapen, malformed or discolored permanent tooth. It can also cause defects to the underlying developing jaw bone. The affected permanent tooth may then need treatment when the child is older to correct cosmetic problems which may arise as a result.
