Understanding Pediatric Pulp Therapy
The “pulp” of a tooth is not visible to the naked eye. Found at the center of each tooth, it consists of nerves, tissues, and blood vessels that provide essential nutrients and oxygen to the tooth. However, the pulp can become damaged in various ways, especially in children. Most commonly, tooth decay or traumatic injury leads to painful pulp exposure and inflammation.
Pediatric pulp therapy, which includes procedures such as root canals, pulpotomies, pulpectomies, and nerve treatment, aims to treat, restore, and save the affected tooth.
At Sky Pediatric Dentistry in Glasgow, KY, our pediatric dentists perform pulp therapy on both primary (baby) teeth and permanent teeth. Even though primary teeth will eventually be replaced, they are vital for proper speech, chewing, and guiding the alignment and spacing of permanent teeth.
Signs of Pulp Injury and Infection
When the pulp becomes inflamed or injured, the pain can be severe. While the cause may not always be visible, it is clear that the child needs to be evaluated by a pediatric dentist. Other signs to look for include:
- Constant unexplained pain
- Pain at night
- Sensitivity to hot or cold food and drinks
- Swelling or redness around the affected tooth
- Unexpected looseness or mobility of the affected tooth
When Should Your Child Receive Pulp Therapy?
Every case is unique. The pediatric dentist will evaluate factors such as the child’s age, the tooth’s position, and overall health before determining whether to extract the tooth or attempt to save it with pulp therapy. Here are some potential consequences of premature tooth extraction:
- Shortened arch length
- Lack of space for permanent teeth to emerge
- Permanent teeth may grow in improperly or be misaligned
- Opposing teeth may grow abnormally
- Premolars may become impacted
- Remaining teeth may shift to fill the gap
- Abnormal tongue posture
How is Pulp Therapy Performed?
To begin, the pediatric dentist will conduct a visual exam and review X-rays of the affected area. Based on the extent and location of the pulp damage, treatment will be determined. The most common pulp therapy treatments are pulpotomies and pulpectomies.
- Pulpotomy: If the root pulp remains unaffected by injury or decay, the pediatric dentist may only remove the damaged pulp and decay from the pulp tip. The remaining healthy pulp and tooth structure are left intact. The empty space is then filled with a biocompatible material to prevent infection and soothe the pulp root. Typically, a crown is placed over the tooth to restore strength and reduce the risk of fractures.
Pulpotomy is versatile and can be used as a standalone treatment for both primary teeth and growing permanent teeth or as the first step in a full root canal procedure. - Pulpectomy: In more severe cases of decay or trauma, the entire pulp, including the root canals, may need to be removed. The pediatric dentist will clean the root canals and fill them with a biocompatible material. Multiple office visits may be required. For primary teeth, resorbable materials are used, while non-resorbable materials are used for permanent teeth. Once the pulp has been treated, a crown is placed on the tooth for added strength and support. We offer both traditional stainless steel crowns and white crowns made of zirconium for those concerned about aesthetics.
