As children’s teeth develop and change, they are more likely to experience tooth sensitivity. On the other hand, certain types of pain may indicate more significant problems. To locate the best remedy, you must first figure out what is causing the pain.

Here are the five common reasons for tooth sensitivity to be aware of.

Untreated Cavities

Cavities are unpleasant for everyone, but especially for youngsters. Your child may have a cavity if they have sensitivity on one tooth or in a specific place. If left untreated, these microscopic patches of tooth rot originate at the enamel and appear as white spots that darken with time. As the inner nerve is exposed, a hollow gets increasingly sensitive as it expands.

Cavity prevention and treatment require good dental hygiene habits and regular visits to your child’s dentist for routine checks.

Cracked Teeth

Some children, like adults, grind or clench their teeth at any time of day or night. Teeth can be harmed by this behavior, resulting in microscopic cracks or fractures. Chewing food might be difficult and uncomfortable as a result of this.

Infection of the Sinus

Teeth sensitivity can sometimes have nothing to do with the mouth. Sinus infections and allergies, believe it or not, can produce tenderness on the roof of your mouth. Sinus pressure or build-up can irritate your child’s nerves or gums, making them sore.

Teeth Replacement

There can be extreme pain associated with new teeth coming in, whether your toddler is growing baby teeth or your kindergartener lost their first tooth. Sensitivity is sometimes caused by the pain of the tooth breaking through the surface. Hot or cold meals and even the air might irritate these new, more sensitive chompers.

Too Much Sugar Consumption

Although sugar is safe in modest amounts, too much sugar combined with insufficient brushing might cause your child’s teeth to become sore. Excessive sugar causes the enamel that protects your teeth to break down, exposing your teeth to sensitivity.

Avoid sugary snacks like cookies and candies, and keep in mind that typical children’s drinks can comprise a lot of sugar, so watch out for what your children ingest.

Tooth Sensitivity in Children: What to Do?

Although some tooth sensitivity is unavoidable as your child grows older, there are some things you can do to relieve the pain and safeguard their teeth.

Dental Sealants

Dental sealants may provide much-needed comfort if your child has a lot of cavities, which are the core cause of tooth sensitivity. Sealants operate as a barrier to cavity-prone areas, preventing plaque build-up and subsequent cavities. This long-lasting treatment will keep your child’s teeth safe for many years.


Fluoride is an effective treatment option to avoid tooth decay and strengthen tooth enamel. Consider incorporating fluoride mouthwash or toothpaste into your child’s oral hygiene routine. It can help your youngster prevent sensitivity by strengthening and protecting teeth throughout time.

Many children’s dentists give fluoride treatments in the form of a foam, gel, or varnish that contains a higher dose. To make the experience more fun, kids can choose one of their favorite tastes.

Make The Switch to Sensitive-Tooth Products

Try switching out the goods you’re using if your youngster is experiencing mild sensitivity. There are numerous sensitive-friendly goods available for both children and adults. Choose sensitive-tooth toothpaste or soft-bristle toothbrushes instead of hard or medium bristle toothbrushes.

Visit A Dentist For Kids

You can lessen sensitivity by ensuring that your youngster brushes, flosses, and has frequent dental checkups with the best dentist in Dundas. These consistent oral hygiene routines can help your child avoid tooth sensitivity now and in the future.


Don’t overlook your child’s tooth sensitivity the next time they complain. Even if it’s a simple fix like switching toothpaste, you want to be sure it’s not something more serious.
