Tooth Sensitivity in Kids

In healthy teeth, a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin. Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). The American Dental Association explains that, when dentin loses its protective covering of enamel or cementum, these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

Causes of Tooth Sensitivity in Kids

There are a few different things that can cause tooth sensitivity in kids. Common causes can include:

Over-brushing

The most common is over-brushing. When kids brush their teeth too hard, it can actually wear down the enamel and make the teeth more sensitive. You should teach your child to brush gently, using circular motions and not applying too much pressure.

Tooth decay

Another common cause of tooth sensitivity is tooth decay. When cavities form, they can expose the inner layers of the teeth, which are more sensitive. This can lead to pain and discomfort when eating or drinking cold or hot beverages.

Teeth grinding

Teeth grinding (or bruxism) is another common cause of tooth sensitivity in kids. If your child grinds their teeth at night, it can wear down the enamel and make the teeth more sensitive. If you think your child may be grinding their teeth, talk to their dentist about it.

Gum Disease

If your child has gum disease, it can also cause tooth sensitivity. Gum disease is an infection of the gums that can damage the tissue and bone around the teeth. If not treated, it can lead to tooth loss.

Fractured teeth

If your child has a fractured tooth, it can also cause sensitivity. A fracture can expose the inner layers of the tooth, which are more sensitive. This can lead to pain and discomfort when eating or drinking cold or hot beverages.

Treating Tooth Sensitivity in Kids

Once you know the cause of your child’s tooth sensitivity, you can start treating it. Some common treatments include:

Brushing with a desensitizing toothpaste

If over-brushing is the cause of your child’s tooth sensitivity, you can try using a desensitizing toothpaste. These toothpastes contain ingredients that help to protect the enamel and reduce sensitivity.

Fluoride treatments

Fluoride is a mineral that helps to strengthen the teeth and make them more resistant to decay. If your child’s tooth sensitivity is caused by cavities, their dentist may recommend a fluoride treatment.

Wearing a nightguard

If your child grinds their teeth at night, their dentist may recommend that they wear a nightguard. A nightguard is a custom-fitted mouthguard that protects the teeth from grinding and clenching.

Treating gum disease

If your child has gum disease, they will need to see a dentist for treatment. Treatment options can include scaling and root planing (deep cleaning), antibiotics, and surgery.

Fractured teeth

If your child has a fractured tooth, they will need to see their dentist for treatment. Treatment options can include bonding, crowns, and veneers.
