Sensitive Teeth In Children

Sensitive Teeth In Children

Tooth sensitivity can be uncomfortable and affect kids in different ways. Having sensitive teeth could mean giving up certain foods, mood changes, and irritability in children. By understanding what causes tooth sensitivity and how to both prevent and treat it, you can help your child avoid these symptoms.

Causes of Tooth Sensitivity in Kids

Many of the causes of tooth sensitivity in children can be traced back to poor oral hygiene. This is why it’s crucial to help your child adopt healthy dental habits as young as possible. Here are some causes of tooth sensitivity in kids and what the tooth pain may be telling you:

1. Poor brushing habits

It’s important to establish proper brushing techniques from an early age, not only to prevent cavities but also to protect the gums and enamel. If your child brushes his/her teeth too hard, it could result in enamel and gum erosion, which makes their teeth more sensitive to hot and cold. To avoid this problem, teach your children how much pressure to apply as they brush their teeth with a soft toothbrush.

2. Cavities

If your child does not brush and floss his/her teeth often enough, then tooth decay begins to take effect, which will cause sensitivity and discomfort in your child’s teeth. To prevent this cause of tooth sensitivity, make sure your children brush their teeth at least twice a day for approximately two minutes.

3. Sinuses

Unfortunately, sinus infections can affect more than just the nose. If your child is prone to sinus problems, he/she may experience tooth sensitivity near the top of the mouth. This is due to the proximity of the sinuses to the roof of the mouth. As sinus pressure builds, it can cause your child to feel pain as though the mouth is infected too. Your dentist should check to make sure this symptom isn’t an actual cavity or abscess.

4. Teeth Grinding

This is a severely bad habit that negatively affects your child’s dental health and is likely to cause tooth sensitivity. Excessive tooth grinding can cause hairline cracks in the teeth that cause mouth pain when your child bites down on something or chews food. Misaligned teeth can also contribute to these hairline cracks.

5. Fillings

More specifically, it is a metal amalgam fillings that can cause unpleasant tooth sensitivity. This type of filling acts as a shortcut that conducts heat faster than your child’s regular tooth enamel.  Since this type of filling is extremely sensitive to changes in temperature, it also causes teeth to expand and contract quickly, putting more pressure on the tooth nerve. This occurrence can also contribute to more hairline cracks in your child’s teeth.

6. Losing Baby Teeth

When your child begins losing more baby teeth and growing permanent ones, it won’t take much to make them feel sensitive and painful. The emergence of new teeth can be miserable on its own, but other factors such as hot and cold temperatures, food, and air can make painful contact as well.

Treatments Available for Sensitive Teeth

Unfortunately, certain causes of tooth sensitivity cannot be prevented, but they can be treated to improve your child’s quality of life.

Improve Your Child’s Oral Hygiene

When it comes to preventing and treating sensitive teeth, it’s all about taking a proactive approach to your child’s dental health. Encourage your children to brush their teeth regularly and make it part of their daily routine. It’s also a good idea to monitor your children while they brush to make sure they are using the best techniques.

Use Products Designed for Sensitive Teeth

There is a multitude of high-quality toothpaste and toothbrushes made specifically for sensitive teeth available on the market. Toothpaste for sensitivity works by desensitizing the nerve within the tooth, so sensations from the tooth’s surface do not reach the nerve. You should also take care when choosing a toothbrush for your child’s sensitive teeth and ask your dentist for recommendations.

Fluoride Treatments

Fluoride is another option, and these treatments involve applying a clear liquid varnish to the teeth in the dentist’s office. Fluoride helps to strengthen and protect teeth, so you’ll find that your child has fewer issues with sensitivity than before. If your child has not seen a dentist for a while or has not gotten a fluoride treatment before, it’s time to be your child’s advocate and make an appointment.
